Rhodolirium andicola

Rhodolirium is a small South American genus in the tribe Hippeastreae of the family Amaryllidaceae. Although originally described by Philippi in 1858 [1] it has long remained buried in other taxa, principally Hippeastrum and more recently Rhodophiala . Only in recent years has it been rehabilitated. [2] [3]

Contents

Restoring the genus was first proposed by Naranjo & Poggio (2000), [4] and accepted by Ravenna in 2003, [5] although he used the name Rhodolirion , originally used by Baker (1878) in his very broad construction of Hippeastrum including both Rhodophiala and "Rhodolirion". He also renamed Rhodolirium andinum as Hippeastrum rhodolirion. [6] Later he elevated Rhodolirion to the status of subgenus, with H. rhodolirion (subsequently Rhodophiala rhodolirion ) [7] as the type species . [8] Subsequently the genus has been treated as part of Rhodophiala. [9] [2]

Description

Flowers single or pluriflor, perigone infundibular (funnel shaped) with elongated floral tube. Paraperigonium, if present, has free segments. Stigma capitate. [2]

Taxonomy

For early treatment of Rhodolirium, see Taxonomy of Hippeastrum. The rehabilitation has yet (as of February 2016) to be recognised by the World Checklist of Selected Plant Families, [10] but is by the Missouri Botanical Gardens, with six species. [11] The ability to resolve phylogenetic relationships based solely on morphological data is limited in the Amaryllidaceae, necessitating the use of molecular methods in addition. In their study of the American amaryllidaceae, Meerow et al. (2000) noted that Rhodophiala was polyphyletic. [12] [2]

Subsequently Munoz et al. undertook a detailed study of Rhodophiala/Rhodolirium species and related genera and confirmed the genus as circumscribed was indeed polyphyletic with three species segregating as a sister group to Phycella which they proposed to resurrect as genus Rhodolirium, while the remainder of the species segregated in a separate clade more closely associated with Hippeastrum, which they proposed as Rhodophiala sensu stricto . When the morphology of the two groups thus identified was examined they were distinguishable by Rodophiala having a trifid stigma compared to capitate for Rhodolirium, by the nature of the paraperigon segments, and by their chromosome numbers (2n=18 for Rhodophiala and 16 for Rhodolirium) and their chromosome symmetry. Both groups appeared to be monophyletic and their differences sufficient to justify separation into two distinct genera. Rhodophiala and Hippeastrum appeared sufficiently close to explain their treatment as a single genus in older classifications, but their separation was consistent with the study by Meerow et al. [2]

The proposal to separate the two genera supports Ravenna's morphological studies, with Rhodolirium montanum (formerly Rhodophiala rhodolirion) as the type species for the new genus. Subsequent phylogenetic analysis by Garcia et al. (2014) confirmed this distinction between the genera and proposed dividing Hipppeastrea into two subtribes, Hippeastrinae and Traubiinae, placing Rhodophiala in the first and Rhodolirium in the second. [3]

Subdivision

Five to six species. [2] [9]

Distribution and habitat

From northern Chile, in coastal vegetation zones to Osorno province in the south, at altitudes of 150–2500 m. Also in Argentina. [2]

Habranthus (copperlily) was a formerly recognized genus of tender herbaceous flowering bulbs in the subfamily Amaryllidoideae of the family Amaryllidaceae.

Ammocharis is a small genus from sub-Saharan Africa, in the family Amaryllidaceae which includes seven species distributed in Africa. The plant grows as above-ground bulb, preferring seasonally wet, hot, sandy soils and full sun.

<i>Rhodophiala</i> Former genus of flowering plants

Rhodophiala was a genus of herbaceous, perennial and bulbous plants in the Amaryllis family. It consisted of about 30 South American species distributed in southern Brazil, Argentina, and, specially, in Chile. Most of the species are known colloquially as añañuca. It has now been submerged in Zephyranthes.

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

The tribe Griffineae includes 2 genera with 22 species from South America which are actually endemic to Brazil. A typical character of the representatives of the tribe are the flowers - They are with blue or lilac color collected into an umbel. Only the members of this tribe and the genus Lycoris are able to form flowers with such color in the whole family Amaryllidaceae. The plants in this group are typical perennial flowers which are producing bulbs. The leaves are green, with elliptical form in the most of the cases but in some members as in Worsleya they are sword-shaped.

The tribe was originally described by Traub in his monograph on the Amaryllidaceae in 1963, as Stenomessae based on the type genus Stenomesson. In 1995 it was recognised that Eustephieae was a distinct group separate from the other Stenomesseae.
