Alliumheterophyllum (Amaryllidaceae), a new species from Henan, China
Alliumheterophyllum D.F.Xie & X.J.He, sp. nov. (Amaryllidaceae), is a new species from Henan, China and is described based on morphological and molecular evidence. It is morphologically most similar to A.dumebuchum in the rhomboid scape in cross-section. However, distinctive differences were det...

description | Alliumheterophyllum D.F.Xie & X.J.He, sp. nov. (Amaryllidaceae), is a new species from Henan, China and is described based on morphological and molecular evidence. It is morphologically most similar to A.dumebuchum in the rhomboid scape in cross-section. However, distinctive differences were detected in perianth color, leaf shape and cross-section, flowers’ density as well as flowering season. Similarly, the karyotype of A.heterophyllum is 2n = 2x = 16 and in A.dumebuchum is 2n = 4x = 32. Phylogenetic analysis based on nuclear ribosomal Internal Transcribed Spacers (ITS) and three cpDNA regions strongly supports that A.heterophyllum is a member of Allium section Rhizirideum and sister to the other species of this section (e.g. A.senescens, A.spirale, and A.prostratum). Currently, only one population and approximately 120 individuals were discovered; the development of scenic spots in this region may affect its growth and threaten this population. Therefore, this new species is preliminarily considered as Near Threatened (NT) according to criteria of the IUCN Red List. |
