HYOPHILOPSIS, A NEW GENUS OF POTTIACE.E 139 



Aug. 7, 1883; leg. Duthie, no. 4099" in Herb. Mitt., c. fr. An 

 unnamed specimen with the above labelHng, sent from Mitten's 

 herbarium unnamed, agrees quite well with an original specimen 

 of A. hicolor (Sikkim ; leg. G. A. Miller, 1901), kindly sent me by 

 Mons. Cardot ; Duthie's plant being only a little more slender 

 and laxer in foliation. 



A. DuTHiEi Broth. {Molendoa Duthiei Broth, olim). Among 

 some unnamed Indian specimens of Ancectangium put into my 

 hands for study from Mitten's herbarium, were three labelled as 

 follows: — "6342a, Ancectangium versicolor, Pahang Gadh, India, 

 July 19, 1886; leg. J. Duthie " ; " 63426, Ancectangium ohtusatum, 

 India; leg. J. Duthie"; "6242c" (probably a slip for 6342c), 

 " Ancectangium, ln(\.\?i,; leg. J. Duthie." The two specific names 

 are no doubt MS. names of Mitten's. The numbering, together 

 with the absence of particulars in the labelling of the last two, 

 would seem to imply that they were collected all at one time. At 

 first sight there is a considerable difference between {a) and (b), 

 the latter being of denser growth, and the leaves being, as the 

 name implies, for the most part obtuse. Closer examination, 

 however, shows that too much dependency must not be placed on 

 this character, for the leaves in {h) are often acute and are very 

 variable, while in [a) they are equally variable, and if more fre- 

 quently acute are also at times quite obtuse ; and the structure 

 and form of capsule, &c., being identical, they must be held to 

 belong to one species. 



The plant marked (c) is certainly closely allied, and, I think, 

 without doubt identical, although the areolation is a little larger 

 and much more pellucid. The capsule agrees, and is marked in 

 all three specimens by a tendency to an asymmetrical form, 

 especially in the immature condition. The lid, which is extremely 

 long-beaked in (a), is usually shorter in (h) and (c), but varies, 

 and apparently the shortness is, in some cases at least, due to 

 accidental causes. A further plant of Mitten's labelled " India ; 

 leg. Duthie," is also a still more compact and obtuse-leaved form 

 of the same thing. 



I have compared these with Ancectangium Duthiei Broth. 

 (Alampi-la, coll. Duthie, no. 12,717) in the British Museum, 

 original specimens of this species, and I have little doubt that 

 they are all referable to that species. The leaf structure agrees 

 exactly, but the Alampi-la plant has shorter, denser leaves than 

 the laxer forms. The basal cells, the basal margin regularly re- 

 curved (almost always on one side only), the somewhat asymme- 

 trical capsule, all agree, and there is really no difference between 

 A. Duthiei and any of the above plants, except in the habit, 

 which in Mitten's (c) is indeed almost if not quite identical ; and 

 in the pointing of the leaves, which, as I have stated, is quite a 

 variable feature. 



The fruiting characters would seem to support the view that 

 it is an Ancectangium rather than a Molendoa. 



This extends the distribution of A. Duthiei, as I suppose, some 

 distance eastward, and also shows it to be a variable plant. In
