Lamium galeobdolon, the yellow archangel, is a species of flowering plant in the mint family Lamiaceae. It is native to Europe and western Asia but it is widely introduced in North America and elsewhere. It is the only species in the genus Lamium with yellow flowers. Another common name for this species is golden dead-nettle. In New Zealand, it is called the aluminium plant or artillery plant. The common names archangel and dead-nettle have been in use for hundreds of years, dating back to at least the 16th century.

Contents

Lamium galeobdolon comprises four closely-related subspecies that are sometimes considered to be four separate species, one of which, the variegated yellow archangel (Lamium galeobdolon subsp. argentatum) from central Europe, is widely present as an invasive subspecies in several European countries outside of its native range and also in New Zealand, Canada, and the United States.

Description

Lamium galeobdolon sensu lato is a perennial plant with square stems growing from 15 to 60 cm (6 to 24 in) tall. The paired opposite leaves are stalked with toothed margins. The leaves are 4 to 7 cm (2 to 3 in) long, and may or may not have silvery markings (an important character used to distinguish subspecies). The inflorescence is a pseudo-whorl of 4–16 flowers (called a verticillaster) clustered around the axil of a leaf-pair. Each flower has bilateral (zygomorphic) symmetry. The calyx is five-lobed and the corolla is yellow with a prominent hood. The flower's lower lip has three lobes with the central lobe often streaked with orange. There are two short stamens and two long ones. Flowering is in late spring to early summer, typically May–June in Britain. A pair of fused carpels give rise to a four-chambered schizocarp. [7] [8] [9]

Identification

Subspecies of Lamium galeobdolonsensu lato are the only taxa in the genus with yellow flowers. All of the subspecies are stoloniferous except subspecies flavidum. The invasive subspecies argentatum is readily distinguished by its silvery white variegated leaves. The two subspecies galeobdolon and montanum can be difficult to distinguish but assuming the plant in question is in full flower, subspecies galeobdolon has a maximum of six (rarely seven) flowers per verticillaster while subspecies montanum averages ten flowers per verticillaster. [10] The hairiness of the lower stems is also a useful clue, with subspecies galeobdolon having hairs on the four ridges only, while subspecies montanum is more uniformly hairy across the faces as well as the ridges. [7] [11]

Lamium galeobdolon subsp. flavidum is notable for the lack of stolons, frequently branched fertile stems with upright flowering lateral shoots, and 10–16 small flowers per verticillaster. [8] [12] An identification key for the remaining taxa follows: [13] [7]

Identification Key
Lamium galeobdolonsensu lato in central and western Europe
(excludes subspecies flavidum)
1a. Leaves and bracts (except for the uppermost) with a distinct silvery pattern (two flexuous bands along the midrib) persisting year around, bracts with wide apical teeth; flowers relatively large
Lamium galeobdolon subsp. argentatum
1b. Leaves generally without silvery pattern (if present, then never forming two continuous flexuous bands along the midrib); apical teeth of bracts mostly narrower; flowers relatively smaller

2a. The uppermost bracts ovate, generally less than twice as long as wide, with more-or-less equally distributed marginal teeth, apical tooth short and obtuse, lowermost bracts narrower or only slightly wider than the uppermost ones; the uppermost leaves shortly petiolate; verticillasters few-flowered (maximum number of flowers usually 4–7); hairs on the lower half of the stem almost entirely confined to the angles
Lamium galeobdolon subsp. galeobdolon
2b. The uppermost bracts lanceolate, more than twice as long as wide, marginal teeth towards the apex more separated, apical tooth long and acute; lowermost bracts mostly distinctly wider than the uppermost ones; the uppermost leaves with longer petioles; maximum number of flowers in verticillasters generally (6–)10–14; hairs on the lower half of the stem more or less equal distribution on the faces and the angles
Lamium galeobdolon subsp. montanum

Other taxa in the group can have marked leaves but those of subsp. argentatum are distinctive: [14]

Permanent silvery pattern on leaf lamina in L. argentatum always forms two flexuous bands along the midrib, mostly not interrupted by the lateral veins. They are distinctive particularly from the late autumn to the early spring when a contrast brownish-maroon colouring develops on the abaxial side and extends to the midrib-zone of the upper leaf side. Although variegated leaves were frequently observed in all other taxa in our study, they never matched the description above. Silvery-grey markings constituted merely separate splashes or flecks (small-sized in L. montanum and L. flavidum, larger in L. galeobdolon), not merged into continuous bands. Thus, a combination of two distinct silvery flexuous bands together with a strong chocolate-maroon zone along the midrib in winter can be regarded as specific L. argentatum markers.

— Rosenbaumová, Plačková & Suda (2004)

In particular, a cultivar of subspecies flavidum known as 'Herman's Pride' has silver-spotted leaves, [15] [ additional citation(s) needed ] but even though the markings are unlike those of subspecies argentatum, the two taxa are sometimes confused.

The base chromosome number of taxa in genus Lamium is x = 9. [16] Lamium galeobdolon subsp. flavidum and subsp. galeobdolon are diploid (2n = 2x = 18) while subsp. argentatum and subsp. montanum are tetraploid (2n = 4x = 36). A few triploid individuals have been reported. [17] The triploids are thought to be natural hybrids between diploid subsp. galeobdolon and tetraploid subsp. argentatum. [18]

Taxonomy

Lamium galeobdolon was first described as Galeopsis galeobdolon by Carl Linnaeus in 1753. [19] Linnaeus himself transferred the species to genus Lamium in 1759, and therefore the correct name in Lamium is Lamium galeobdolon(L.) L. [1] [20] The latter has six homotypic synonyms, [2] one of which, Lamiastrum galeobdolon(L.) Ehrend. & Polatschek, is widely used.

The name galeobdolon (or Galeobdolon) has a long history. [21] It was used by Pliny the Elder in the first century AD. [22] Johann Jacob Dillenius referred to genus Galeobdolon in 1719, followed by Michel Adanson (1763), William Hudson (1778), and dozens of others. [23] George Bentham used Galeobdolon as the name of a section in 1848. [24] Later, in 1864, Paul Friedrich August Ascherson used it as the name of a subgenus. [25] From the time of Linnaeus, numerous authors have used the specific epithet galeobdolon in the names of species. Altogether there are dozens of botanical names that use galeobdolon (or Galeobdolon) at least once. [26] [27] Most of them are synonyms for just a few taxa.

Most authorities with a global scope accept four closely-related taxa, either as subspecies of Lamium galeobdolon(L.) L. [2] [28] [29] [30] or as full species in LamiumL. [31] [8] Other authorities accept one or more taxa in LamiastrumHeist. ex Fabr. or GaleobdolonHuds. [32] [33] [21]

Lamium galeobdolon subsp. argentatum was first described as Galeobdolon argentatum by Miroslav Smejkal in 1975. [34] In a comprehensive and influential treatment of genus Lamium published in 1989, [35] Jacob Mennema reduced the species to forma and placed it in synonymy with Lamium galeobdolon subsp. galeobdolon. Hence subsp. argentatum was neglected for a long time and its invasion history is poorly documented. [36]

Based on nuclear DNA data, Lamium is monophyletic whether L. galeobdolon sensu lato is included or not. Based on chloroplast DNA data, however, the same study found Lamium to be paraphyletic if L. galeobdolon is segregated to genus Lamiastrum. [37] [38] Subsequent studies have found Lamiastrum to be nested within Lamium, [39] [40] [41] that is, a separate genus is not warranted. The recognition of full species in Lamium is likewise not supported by molecular analysis. [42]

Etymology

Both the generic name Lamium and the specific epithet galeobdolon were used by Pliny the Elder in the first century AD. [43] The name galeobdolon has several possible origins. [44] It may come from the Latin words galeo meaning "to cover with a helmet" and dolon meaning "a fly's sting", or it may come from the Greek words galen meaning "weasel" and bdolos meaning "foetid smell". The latter interpretation is likely the source of the old common name 'yellow weasel-snout'. [45]

The common names archangel and dead-nettle have been in use for hundreds of years. In 1578 Rembert Dodoens observed that "Dead nettell groweth every where". [46] John Gerard used the word "archangel" in 1633. [47] Gerard believed the dead-nettles were so-named because their leaves resembled those of the true nettles in the family Urticaceae. [48] The names "Arch-Angel" and "Dead Nettle" appear in the book The English Physitian (also known as the Complete Herbal) published by the English botanist and herbalist Nicholas Culpeper in 1652. Both Dodoens and Gerard believed the name "archangel" referred to members of genus Lamium with "clusters of hooded flowers at the nodes rising along the stems like a choir of robed figures". [49] Others believe the name refers to the wing-like shape of its paired opposite leaves. [44]

Distribution

Lamium galeobdolon sensu lato is native across Europe, western Asia, and portions of the Middle East. It ranges from Ireland and Spain eastward across Europe as far as the West Siberian Plain and southeastward to Iran. [2] Subspecies flavidum is native to the Alps, northern Italy, and the mountain ranges northeast of the Adriatic Sea. The two subspecies galeobdolon and montanum have broadly similar distributions, but the latter extends further west and south than subspecies galeobdolon, which itself has a more northeast distribution. [12] Within Britain and Ireland, subspecies montanum is widespread across England and Wales and locally in southern Scotland and eastern Ireland, [50] while subspecies galeobdolon is restricted to a small area in Lincolnshire in eastern England. [11]

Lamium galeobdolonsensu lato is widely introduced in several European countries outside of its native range, and also in New Zealand, Canada, and the United States, [2] [51] but authorities disagree about the distribution of introduced subspecies. As of April 2024, Plants of the World Online (POWO) claims that subspecies argentatum has been introduced in Great Britain, Ireland, and Italy, [3] but since it is elsewhere reported to be introduced in the Netherlands and Switzerland, [52] [53] the list is incomplete. POWO also claims that subspecies galeobdolon has been introduced in Madeira, New Zealand (both North Island and South Island), and the United States, [5] but iNaturalist data show that subspecies argentatum is the most widespread subspecies in all of these areas. [54] Since authoritative sources based in North America implicitly refer to Lamium galeobdolonsensu lato, [55] [33] [32] [51] [56] POWO's claim is unsubstantiated. The list of U.S. states where Lamium galeobdolonsensu lato is said to occur varies dramatically depending on the source.

Ecology

Lamium galeobdolon sensu lato has been widely introduced as a garden plant (often under the name Lamiastrum galeobdolon), especially in New Zealand, Canada, and the United States where it has escaped cultivation and become an invasive species. In New Zealand, it is listed by the 2020 National Pest Plant Accord and therefore banned from sale, propagation, and distribution throughout the country. [57] [58] [59] It is also listed by the Invasive Species Council of British Columbia in Canada. [60] In the U.S. state of Washington, it is listed as a Class B Noxious Weed and therefore banned from sale by state law. [61] [62] [63] It is also a B-listed Noxious Weed in the state of Oregon. [64]

The variegated yellow archangel (Lamium galeobdolon subsp. argentatum) has become an invasive subspecies in several European countries. In the Netherlands, subspecies argentatum was introduced as an ornamental ground cover, and by 1985 it had become naturalised and recorded in more localities than the native subspecies galeobdolon. [52] It is also invasive in Britain where it spreads by stolons at the rate of 1–2 metres (3 ft 3 in – 6 ft 7 in) per growing season. [65] In western England, it is found far from human habitations, which suggests it did not originate from garden waste and must therefore be spreading by other means. [66] In Switzerland, subspecies argentatum tripled its occurrence in four decades (1980–2020) while exhibiting "a higher growth rate and regeneration capacity" than the native subspecies galeobdolon. [53]

Outside of its native range, the invasive subspecies of Lamium galeobdolon in particular areas is largely unknown. In the Lower Mainland of British Columbia, the invasive entity is said to be a cultivar of subspecies montanum called 'variegatum' (also known as 'Florentinum'). A cultivar of subspecies argentatum called 'Florentinum' (also known as 'variegatum') has invaded the Seattle area in Washington State. [62] [67] [68] [69]

Based on morphological characters, number of chromosomes, pattern of geographical distribution, and phytochemistry, early botanists hypothesized that the tetraploid subsp. montanum originated as a hybrid between the two diploid taxa, subsp. flavidum and subsp. galeobdolon. [70] However, more recent phylogenetic data suggests that subsp. montanum originated from subsp. flavidum alone. Similarly, there is conflicting evidence regarding the origins of the tetraploid subsp. argentatum suggesting that it may or may not have originated from subsp. galeobdolon alone. [71]

Current opinion gives S. blancoana distinct species status, even while some botanists consider it a subspecies of its two close relatives. It differs from S. officinalis subsp. lavandulifolia and S. candelabrum in being prostrate, as opposed to merely low-growing. It also has whorls of 2–6, compared to 6–9 in S. officinalis subsp. lavandulifolia.
