Utricularia multicaulis (Sikkim, India, 7000 to 11,000 feet). 
—The bladders, attached to rhizomes, are remarkable from 
the structure of the antennæ. These are broad, flattened, 
and of large size; they bear on their margins multicellular 
hairs, surmounted by glands. Their bases are united into a 
single, rather narrow pedicel, and they thus appear like a 
great digitate expansion at one end of the bladder. Inter- 
nally the quadrifid processes have divergent arms of equal 
length. The bladders contained remnants of articulate 
animals. 
| Utricularia cornuta, Michx. (United States).—This species 
has been studied by A. Schimper in America, and is the sub- 
ject of a short paper in the ‘ Botanische Zeitung.’ * It grows 
in swampy ground, and presents a remarkable appearance ; 
the aerial part of the plant seems at first sight to consist of 
nothing but almost naked flower-stems a foot in height, 
bearing from two to five large yellow flowers. U. cornuta 
has no roots, its underground stem or rhizome is much 
branched and bears numerous minute bladders. The 
branches of the rhizome throw up here and there grass-like 
leaves which cover the ground without having any apparent 
connection with the flower-stem. The structure of the blad- 
ders is not in any way remarkable, resembling in its general 
features that of the European species. The bladders generally 
contain organic remains; out of 114 only 11 contained no 
débris. The contents include diatoms and small animals,— 
worms, rotifers, small crustaceans; and the hairs lining the 
inside of the bladders give evidence of having absorbed 
matter from the decaying mass.—F. D. | 
PoLYPOMPHOLYX. 
This genus, which is confined to Western Australia, is 
characterised by having a “quadripartite calyx.” In other 
respects, as Prof. Oliver remarks,t “it is quite a 
Utricularia.” i 
Polypompholyx multifida.—The bladders are attached in 
whorls round the summits of stiff stalks. The two antennæ 
are represented by a minute membranous fork, the basal 
part of which forms a sort of hood over the orifice. This
