  • Cheiranthus albiflorus T. Anderson
  • Christolea albiflora (T. And.) Jafri
  • Ermania albiftora (T. And.) Schulz

    Perennial, 3-10 cm tall, clothed with minute, stellate, soft hairs, leafy. Radical leaves narrowly spathulate or oblanceolate, 10-20 mm long, 2-4 mm broad, entire or obscurely 1-3-lobulate; cauline leaves linear or oblanceolate, smaller. Racemes 10-15-flowered, sometimes bracteate below. Flowers 5-6 mm across, white; pedicels up to 5 mm long in fruit, ascending or erect. Sepals c. 3 mm long. Petals 7-8 mm long, 3-3.5 mm broad. Stamens c. 3: 3.5 mm long. Siliquae (very young) c. 5 mm long, 1 mm broad, linear, densely pubescent with minute stellate hairs; style c. 1 mm long, glabrous with short, sub-bibbed stigma; seeds not seen.

    Fl. Per.: June-July.

    Type: W. Tibet. Zanskar, 3600-4800 m, Thomson (K).

    Distribution: Endemic to W. Tibet.

    Incompletely known from the type gathering only. It occupied an odd place under Christolea Camb. (Ermania Cham. ex Schulz) because of its stellate hairs and narrow, almost entire leaves. It is very close to the previous species except for the small size, leafy stem and smaller leaves. Phaeonychium surculosum (Busch) Botsch. (in Nov. Syst. Lening. 17:177.1955; Parrya surculosa Busch in Kom., Fl. U.R.S.S. ed 2, 8:647. 1939; Wakilia qfghanica Gilli l.c. 221) from C. Asia and Afghanistan, do not seem to be different from it.
