A. caudigerum, Hance in Journ. Bot. vol. xix. (1881) p. 142. 
The genus Asarum, of which up to very recent times only 
five representatives were described, has of late received 
many remarkable accessions, especially from China and 
Japan, raising the number of known species to upwards of 
a dozen. Though not so striking a plant as the dA. 
macranthum figured at Plate 7022 of the volume for 1888, 
A. caudigerum is sufficiently remarkable for the caudate 
tips of the three perianth-lobes, recalling those of Masde- 
vallia Carderi, the figure of which accompanies this in the 
present number of the Magazine. Its nearest allies are 
A. Hookeri, Field. & Gard. (Sert. Plant. t. 32), a North- 
west American species, and A. himalaicum, H. f. & T., of 
the Sikkim Himalaya. Of these two the former has tails 
to the perianth-lobes, but the lobes themselves are not 
connate, as in A. caudigerum, but are separate nearly to the 
base, and the connectives have longer subulate tips. In 
Herbarium specimens of A. caudigerum from the Hong 
Kong Gardens the leaves are more hastate than in those here 
figured, the flowers larger, of the shape of Fig. 1 of the 
plate, and the anthers have much longer points. Hance, 
on the other hand, describes the anthers of native spe- 
cimens as crowned with a small globose process, the 
ovarium as subinferior, and the throat of the corolla as 
not constricted. Possibly more than one species 18 1n-
