this species is drawn, and here HEMSLEY has added: „This may prove to be specifically the same as A. flaccidus Bge«.
Neither BUNGE nor HEMSLEY tell if the pappus is single or double (uniseriate or biseriate). If specimens from Alatau (KARELIN and KIRILOFF) and from alpine Turkestan (A. REGEL, 18 7 9) are rightly named as A. flaccidus Bge — what I believe they are —, this species has biseriate pappus, but the outer rays are usually few and short, often difficult to discover. On the other hand the figure of A. Boweri in Hook. Icon. shows only uniseriate pappus, and the plant, which I have seen at Kew, looks on the whole so different from what I take as A. flaccidus Bunge, that I do not think it possible that they are one and the same species.
Besides the difference with regard to the pappus the species of the Alj5ia-eni are said to be distinguished by the hairiness of the achenes, by the shape and hairiness of the involucral bracts and by the size of the stem and its being monocephalous or pluricephalous.
If we take the species with uniseriate pappus at first we have:
A. altinus L., monocephalous; narrow-lanceolate involucral leaves, ± covered with short, rather stiff hairs; achenes adpressed-pilose. Not found in Himalaya, but ill Pamir, Alatau etc.
A. kirnalaicus Clarke, monocephalous; invol. leaves broadly elliptic-lanceolate, ± leafy and long, pubescent ; achenes densely pilose. Himalaya.
A. tricephalus Clarke, usually tricephalous ; invol. leaves narrow-lanceolate, pubescent; achenes densely pilose. A taller plant than the others. Himalaya.
A. Straclaeyi Hook. f., monocephalous; invol. leaves linear-oblong; foliage leaves (which in all the other species are entire) coarsely serrate or laciniate; achenes »pubescent or silkycc. Himalaya.
A. Boweri Hemsley, usually monocephalous, but with many branches from the same rhizome ; invol. leaves linear-lanceolate, pilose-hairy; achenes sparingly hirsute and with black points. Tibet.
None of these were in the main part of Hedin's collection, but in the small collection from 1896-97, which was presented to Kew Herbarium, HEMSLEY and PEARSON identified some specimens with A. Boweri, which we therefore have to enumerate here:
Aster Boweri Hemsley, in Journ. Linn. Soc. vol. 3o (1895) 113; Icon. plant., pl. 2495, Hemsley and Pearson, in Peterm. Mitteil. Ergänzungsbd. 28 (I 900) 374 ; Hemsley, in Journ. Linn. Soc. 35 (1902) I 81.
Northern Tibet, Sarik-kol, Kwen-lun, 3469 m., 5 th Aug. 1896; Camp X, 5362 m., 23rd Aug. 1896.
Geogr. area: Tibet.
