16. Grubovia Freitag & G. Kadereit, Taxon 60(1): 72 (2011)

Grubovia dasyphylla (Fisch. & C.A.Mey.) Freitag & G.Kadereit (Type).

Description.

Annuals, usually with tumble-weed habit. Stems and leaves with white, simple multicellular hairs that are appressed and obliquely orientated and with scattered yellow short hairs mostly located in the leaf axils. Leaves terete, green, obtuse, with water-storage tissue and C3-type anatomy. Flowers in leaf axils, solitary or in pairs. Perianth of 5 at least half-way concrescent segments, usually pilose; all or three of five segments develop wing-like or spiny projections. Stamens 5, with small anthers. Fruit with hyaline pericarp adherent to the seed coat. Seed embryo horizontal. Perisperm abundant.

Here, we indicate for the first time that the presence of short yellow hairs is the remarkable morphological characteristic of Grubovia that is important for the delimitation of this genus. Grubovia comprises three species mostly distributed in Central Asia. Grubovia dasyphylla has the largest distribution that also includes Tibet and North Himalaya.
