The style morphologies of Astragalus subgenus Pogonophace (Leguminosae) were examined using the scanning electron microscope. The results showed that in most species, there are erect and upwardly pointed trichomes on the style. This kind of structure is exactly a pollen brush. The style of A. craibianus Simps. is glabrous, and there are finger-like projections formed by the epidermal cells only on the stigma. A. hoantchy Franch. has a penicillate stigma. The three types of styles are not… Expand

Intense uplift of the Qinghai-Tibetan Plateau triggered rapid diversification of Phyllolobium (Leguminosae) in the Late Cenozoic
TLDR
Phyllolobium is characterised as a recently diversified genus adapted to the cold and dry habitats of the QTP and its environs, and rapid diversification was likely triggered by consecutive phases of QTP uplift in the Late Pliocene and the Early-to-Mid Pleistocene. Expand

A Preliminary Phylogenetic Study of the Subgenus Pogonophace ( Astragalus ) in China Based on ITS Sequence Data
TLDR
The results of phylogenetic analyses suggest that the subgenus Pogonophace is not a monophyletic group, and the species of sections Bibracteola, Phyllolobium and Trichostylus compose a monophical group with a close relationship to subtribe Coluteinae instead of Astragalus. Expand
MOLECULAR PHYLOGENY OF THE "TEMPERATE HERBACEOUS TRIBES" OF PAPILIONOID LEGUMES: A SUPERTREE APPROACH
TLDR
Hologalegina is the sister group to the clade comprising Millettieae and the other predominantly Old World tropical tribes Phaseoleae, Abreae, Desmodieae, Psoraleeae, and Indigofereae, contrasting with the traditional view that the largely temperate, herbaceous tribes that form HologaleGina are derived from within Milletieae.

Evidence on the monophyly of Astragalus (Fabaceae) and its major subgroups based on nuclear ribosomal DNA ITS and chloroplast DNA trnL intron data
TLDR
Preliminary estimates of the absolute rate of species diversification in Astragalus suggest it may be higher than in some other, often cited, continental or insular adaptive radiations in angiosperms. Expand
