Taxonomic note.

Both Kochia dasyphylla and Echinopsilon divaricatus were described in the same year (1841). The priority of the name Kochia dasyphylla (now Grubovia dasyphylla ) is based on the publication date of the book by Fischer and Meyer (22 July 1841) against the name Echinopsilon divaricatum published by Karelin and Kiriloff in the Bulletin de la Société Imperiale des Naturalistes de Moscou, vol. 4 (8 September 1841).

Description.

Annuals up to 30 cm with tumble-weed habit. Stems red or green, pilose at younger stage and moderately glabrescent at fruiting (white or greyish hairs often turning fulvous after drying). Leaves 1.0-4.0 × 0.1-0.3 cm, with appressed or spreading white hairs up to 6-7 mm long. Perianth segments 5, pilose (Fig. 44B ), sometimes glabrescent at fruiting stage with spiny (subulate or acicular), star-like projections up to 3.0 mm long that can be glabrous or with simple white hairs. Stamens 5. Fruit ovoid.

Habitat.

Rocky or sandy areas at elevations of 3000-4600 m. A rare plant in North India ( Hartmann 1983, sub Basssia fiedleri ).

Phenology.

Flowering: July-September; fruiting: August-October.
