Dickoré, W. B. & Kriechbaum, M.: Oxytropis iridum (Leguminosae), a new species from SE Tibet (Xizang, China), including phytogeographical notes. — Willdenowia 36: 857–865.-ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem. doi:10.3372/wi.36.36216 (available via http://dx.doi.org/)
Oxytropis iridum is described as a species new to science from the Inner E Himalaya of the Xizang Autonomous Region. The new species is well defined by its morphological traits, geographical distribution and habitat preferences and belongs to the largest and probably most controversial, typical subgenus of Oxytropis. It is apparently most closely related to the circumarctic O. deflexa (Tibet, N Asia, W North America) and to the W Himalayan endemic O. mollis.
