Description

The perennial plants with bulbs [6] produce 5-7 linear leaves [7] with a prominent mid vein, [8] which form a pseudo-stem of up to 30 cm in length. Each leaf may reach lengths of up to 50 cm and widths of 2–4 cm. [6]

The bisexual, radially symmetrical flowers are intensely fragrant. [9] [10] [6] They resemble the flowers of Pancratium . [11] [3] They are produced in groups of 2-4 flowers, which have a 12–25 cm long perianth tube with three nectariferous channels. These features could suggest moth pollination. The pedicel is 1.5–3 cm long. With 8 cm of length, the outer tepals are slightly longer than the 7 cm long staminal cup. [8] The incurved stamens with dorsifixed anthers are inserted in deep notches of the staminal cup, or corona. [6]

Reproduction

Generative reproduction

Pamianthe is presumed to be moth pollinated based on their floral morphology. [12] Specifically sphingid moths come into question. [8] The plant is self compatible. The fruit takes 12–15 months to mature. [11] [6] [10] Rapid germination occurs under humid conditions at 16-21 °C. [13] [6] Seedlings reach maturity within four to five years. [11] [14]

Vegetative reproduction

Pamianthe peruviana can also reprocuce asexually through stolons. [15] [16]

Cytology

The diploid chromosome count of Pamianthe is 2n = 46. [17] [18]

Etymology

The generic name Pamianthe refers to Major Albert Pam. [19] [20] [8] [21] The specific epithet peruviana references this species origin in Peru.

History

Pam discovered the species in 1926 on a bulb collecting expedition in Peru. [20] Other sources state he received bulbs from Peru in 1928. [16] [8] Pam, who introduced the species to horticulture, was a friend of the horticulturalist Edward Augustus Bowles (1865 - 1954), [21] [19] to whom he gave a Pamianthe peruviana specimen in the 1930s. [22] He also donated Pamianthe peruviana to the Royal Botanic Gardens, Kew in 1937. [23]

Habitat

It was found along streams in the warm to temperate northern region of Peru at elevations of 1800 m above sea level. [24] [25]

Taxonomy

Taxon authorship

There is conflicting information on the taxon authorship of this species. One source claims it to be anonymous, [26] whereas most give Otto Stapf as the taxon author. The type specimen, which was cultivated by Albert Pam in the United Kingdom, is associated with Stapf as the taxon author. [27]

Role as type species

Pamianthe peruviana is the type species of the genus Pamianthe. [8]

Synonym status of Pamianthe cardenasii

Despite being the same taxon, [2] [8] it has been reported that Pamianthe cardenasii were a bulbous geophyte, and Pamianthe peruviana were an epiphyte. [28]

Phylogeny

Some degree of possible hybridization was identified between Pamianthe peruviana and Pamianthe ecollis . According to a molecular clock analysis, both species shared a common ancestor 18.22 million years ago. This means Pamianthe peruviana diverged in the early Miocene. [1]

Conservation

It is presumed to be extinct in the wild. [29] [30] [31] It is not known when it was last recorded. [32] According to the Cambridge Botanic Garden the conservation status has not been evaluated. [33] Under its synonym Pamianthe cardenasiiTraub it has also been classified as not evaluated by the national herbarium of Bolivia in 2005. [34]

Ex-situ conservation is ensured in several living collections, such as the living collection of the Gothenburg Botanical Garden, the Royal Botanic Garden Edinburgh Living Plant Collections, [35] the Oxford Botanic Garden, [4] as well as private collections.

Horticulture

Despite it being very rare in cultivation, [36] it can be easily cultivated as a houseplant if kept in a well aerated substrate, [37] because it is intolerant of waterlogged conditions, which rapidly induce root rot. [11] Ideally, it should be cultivated under moderately bright, humid conditions at temperatures of 18-30 °C. [36] Seeds can be sown all year round. The optimal time is March–August. The remaining months are less optimal. The germination temperature should not be below 20 °C. [38] Pamianthe makes a good greenhouse or container display. [39] It is also suitable as a long-lasting cut flower. [16]

<span class="mw-page-title-main">Asparagales</span> Order of monocot flowering plants

Asparagales is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985 and then the APG in 1998, 2003 and 2009. Before this, many of its families were assigned to the old order Liliales, a very large order containing almost all monocots with colorful tepals and lacking starch in their endosperm. DNA sequence analysis indicated that many of the taxa previously included in Liliales should actually be redistributed over three orders, Liliales, Asparagales, and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. In the APG circumscription, Asparagales is the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species.

<span class="mw-page-title-main">Clinantheae</span> Tribe of flowering plants

Clinantheae is a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was described in 2000 by Alan Meerow et al. as a result of a molecular phylogenetic study of the American Amaryllidoideae. This demonstrated that the tribe Stenomesseae, including the type genus Stenomesson was polyphyletic. Part of the tribe segregated with the Eucharideae and were submerged into it, while the other part formed a unique subclade. Since the type species of Stenomesson was not part of the second subclade, it was necessary to form a new name for the remaining species together with the other genera that remained. This was Clinanthus, the oldest name for these species, and consequently the tribe Clinantheae.
