@ARTICLE{TreeBASE2Ref17382, author = {Hanno Schaefer and Alexander Kocyan and Susanne S Renner}, title = {Linnaeosicyos (Cucurbitaceae), a new genus for Trichosanthes amara, the sister species to all other Sicyeae}, year = {2007}, keywords = {}, doi = {}, url = {}, pmid = {}, journal = {Systematic Botany}, volume = {}, number = {}, pages = {}, abstract = {The Old World genus Trichosanthes has flowers with strikingly fringed petals, and Linnaeus therefore placed a species from Hispaniola that he only knew from an illustration (showing the fringed petals) in that genus. The species remained hidden from the attention of subsequent workers until acquiring new relevance in the context of molecular-biogeographic work on Cucurbitaceae. Based on molecular data, it is the sister to all Sicyeae, a New World clade of about 125 species in 16 genera. We here place this species in a new genus, Linnaeosicyos, describe and illustrate it based on new collections, and discuss its phylogenetic context using molecular and morphological data. Judging from Dominican amber, elements of the flora of Hispaniola date back at least 30 my, and the occurrence on the island of five endemic species of Cucurbitaceae (Linnaeosicyos amara from Benincaseae, Melothria domingensis from Sicyeae, Sicana fragrans from Cucurbiteae, and the sister species Anacaona sphaerica and Penelopeia suburceolata also from Cucurbiteae) points to its long occupation by Cucurbitaceae.} }
