Interesting genus. These four plants give some idea of the remarkable range of shape, structure, and coloration of the inflorescence in the genus, but they all belong to the group of species with a single trilobed leaf. In other species which have a single leaf, the blade may be cut radially or pedately into five to many segments, whilst some species have two (rarely three) leaves. Over a hundred species are known, but, as Dr. Stapf has already pointed out, t. 9212, our knowledge of many of them is still very incomplete. A. candidissimum appears to be referable to section Auriculata of Engler's monograph (Pflanzenreich, IV. 23 F.), and to be nearest to A. Fargesii S. Buchet. The latter differs primarily in the colour of the inflorescence, the spathes being purplish with paler lines, but it also differs in having smaller and elliptic lateral leaflets, in its male flowers being scattered over the axis (not contiguous as in our plant), and in the connective being produced into a shining white apiculus. A. candidissimum was discovered and introduced into cultivation by Forrest who collected it originally in June 1914 in the Fengkow Valley (about 15 miles west of Yungning),.
