W. Tibet, Camp CCXI, East of the lake Manasarovar, 4654 m., 24th July 1907 (flow.).

Geo, r. area: (of the var.) : Tibet and Himalaya. In the Kew Herb. I have only seen one specimen of it; it lies amongst plants of the following species and was collected by J. D. HOOKER at Sikkim, 24th July 1849.

That A. flaccia'us Bunge and A. laetes-ocheeta Benth. are the same species I feel convinced after examination of the ample material in the Kew Herb. But under the latter name is also found another plant, which perhaps is DE CANDOLLE'S original Heteroclueta asferoides. In Kew Herb. there are several sets of specimens collected by ROYLE, and DE CANDOLLE'S plant was founded on material given him by ROYLE, but as ROYLE'S sets are mixtures of several species and as DE CANDOLLE'S description is quite insufficient, I dare not use his name for a species which I am going to describe below and which has been mixed up with A. flaccidus (A. helerockeeta), from which it seems fairly distinct.

A. Hednii Ostf. nov. sp.; A. heterochuela Benth. pro min. parte; (?) Heteroch(eta as/eroia'es De Cand. Prodr. V (I 8 3 6) 2 8 2 .

Sect. Alj5ig eni. Planta perennis, ± hirsuta, monocephala; rhizoma breve (praemorsum) radicibus + numerosis, tuberosis fasciculatis instructum. Folia rosulata oblonga vel oblongo-obovata, integra, obtusa ; folia caulina minora, oblonga, basi semiamplectente. Brateae involucri lineares vel oblongo-lineares, acutæ, subtus pilis + glanduliferis atratisque tectae. Capitula magna (diametro 2.5-3 mm.); corollae florum exteriorum angustae purpureo-lilacinæ, interiorum flavae; achenia dense pilis albis adpressis tectae. Ceterum ut A. fiaccidus cui proxime.

This plant is easily distinguished from the other species by its tuberous adventitious roots and the silky-hairy achenes. It differs further from A. Jiaccidus in the more even hairiness of the stem and stem-leaves, the latter usually being more numerous and larger.

The silky-hairy achenes point towards the Heterochceta asteroides D. C., which is described as having »achaenio villoso« , while CLARKE when transferring it to Aster under the name of A. heterockeeta says: »achaenium pilis tenuibus patulis inspersumcc. DE CANDOLLE has only had the upper part of a plant and has consequently no description of the tuberous roots. But also if we admit that DE CANDOLLE'S description covers our plant, it still needs a new name when transferred to Aster.

This plant is in HEDIN'S collection:

S. W. Tibet, on the way between Camp CCIII, Dara-sumkor, 4931 m., and Camp CCIV, Bak-gyäyorap, 4870 m., the northern foot of Himalaya, I 6th July 1907 (flow.)
