User:Rupert Clayton/Draft of List of Sisyrinchium species

From Wikipedia, the free encyclopedia

Approximately 211 species are currently accepted within the genus Sisyrinchium.[1][2] Botanists have divided the genus using several schemes in the past, but the current division into 10 sections is rooted in phylogenetic analysis and mapped to consistent morphological characters.

This list shows currently accepted species, subspecies and varieties of Sisyrinchium for each section. Unless otherwise stated, this article follows Plants of the World Online (POWO) for accepted taxa and synonyms.[1] The foundation for placement of species into sections is a 2017 study by Camila Dellanhese Inácio and collaborators that analyzed 171 samples from 110 Sisyrinchium taxa (96 published species, 3 infrataxa, and 11 unpublished taxa from south and southeast Brazil).[3] That study identified 10 distinct clades within the genus, into which 108 of the 110 taxa could be placed with confidence.[4] Two species, S. chilense and S. elegantulum, showed conclusive indications of reticulate evolution, with parentage from more than one section.[5]

Beyond the assignments explicitly made by Inácio et al, there are several reasons that other species can be confidently assigned to one of the 10 sections. Some sections are practically identical to a section or subgenus proposed by previous writers. An example is Inácio's Section Sisyrinchium, which corresponds to Section Bermudiana sensu Benth. & Hook and includes all the North American species placed in Section Sisyrinchium by Pierfelice Ravenna.[6] There are also some scenarios where Inácio's paper provides sufficient information to confidently assign taxa to sections, such as assigning an infrataxon to the same section as its parent or sibling taxon. Section assignments can also be made for undescribed taxa studied by Inácio that have since been formally described. And several papers describing new taxa since 2017 have used Inácio's terminology to determine the appropriate section for the new species.

Section Hydastylus

[edit]

Phylogenetic analysis by Inácio et al identified Section Hydastylus as the first lineage to diverge from the genus, and thus as a sister to all the other sections.[7] Morphologically, plants in this section can be distinguished by the combination of having inflorescences with a single terminal rhipidium, and basal leaves but no cauline leaves. Species in Section Hydastylus are similiar to those in Section Segetia in many respects, but lack any bract below the spathes of the inflorescence and have stems that are obviously winged.[8] They have yellow, disk-shaped flowers without trichomes (in common with many other sections). Species within Section Hydastylus are found across a wide area from the Páramo and Puna regions of the northern Andes, through Central America and the mountains of Mexico to western North America as far north as Vancouver Island. One species, S. acre, grows in Hawaii.[9]
