in an advanced state of growth, the chief difference between 
the description of his plant and that of S. and W. being the 
lobate upper segment of the calyx of the former. I find, in one 
or two Utricularie of this group, that this lobe of the calyx, ori- 
ginally entire, or at most retuse or emarginate, often splits more 
or less towards maturity, thus presenting quite a bilobate form. 
The appendaged seeds are very remarkable; but in this respect 
they differ from other Himalayan species of the same series 
(including the well-known U. orbiculata of Wallich) merely in the 
form of the produced epidermal cells of the testa, which, as noted 
by Dr. Wight, in this latter species are glochidiate or capitate, 
while in the Kumaon plant they are elongated hairs from the 
extremities. 
The Sikkim and Khasia collections of Dr. Hooker include two 
or three new species belonging to the same group with these 
plants; but I have not been fortunate enough in every case to 
meet with matured seeds, the further examination of which is 
very desirable. "These singular Utricularias constitute a most 
interesting section of the genus, characterized by small stature, 
orbiculate, reniform, or obovate-spathulate leaves, very unequal 
calyx-lobes, the lobed, more or less plane, lip of the corolla, and 
(во far as sufficiently matured specimens enable me to speak) the 
appendaged seeds; perhaps, too, the dehiscence of the capsule, 
and the ultimately more or less reflexed inferior lobe of the calyx, 
may be common to them. Although these characters confer a 
striking individuality, yet I do not discover that the species pre- 
senting them are entitled to a rank superior to that of a sub- 
genus. They are, too, so essentially Utricularia, that by separating 
them we should open a door yet more widely to a destruction of 
the genus as interpreted in books—already, indeed, impending 
from the separation, by some writers, of certain South American 
forms. It is perhaps possible that a carefully conducted series of 
observations upon the embryo and structure of the seed may lead 
to a different conclusion; but until such observations are forth- 
coming, the more correct course is undoubtedly to retain them as 
a section of the genus. Dr. Wight, in his valuable ‘Icones’ 
(vol. iv.), figures and describes twenty-three species. Some of 
these, in most cases identified in his herbarium, after examination 
and comparison with other series, I have thought it quite im- 
possible to maintain, and have accordingly reduced them. Dr. 
Wight particularly observed the characters afforded by the surface 
and form of the seed in certain species, resting, in some cases,
