opportunity of finally determining, rather than that а 
separate generic group should be founded on them. Be- 
sides the expressed difference, however, the anthers vary 
in form from those of all the described species of Сохого- 
Bus, and the stamineous crown, instead of growing dis- 
tinctly upon the filaments, is grown to the bottom of the 
faux, while its connexion with the filaments can only be 
traced by attentive dissection. | 
The drawing was made from a specimen kindly sent us 
by Sir Abraham Hume, from his hothouse at Wormley- 
bury. The species was introduced some few years ago from 
Mexico, by Mr. Lambert, who raised it at Boyton House 
from seed. 
A twining shrub, 15 feet high or higher; stem corky 
and furrowed at the lower part; branches round, with a 
tawny fur; hairs articulated. Leaves distant, membranous, 
roughishly furred, elliptically oblong, lanceolately acumi- 
nate, contractedly cordate at the base, the lobes meeting 
together, from 2 to 3 inches long, and from an inch and a 
half to two inches broad, nettedly veined underneath: pe- 
tioles thickish, bent, 2 or 3 times shorter than the blade; 
interpetiolar fringe but slightly distinguished from the ge- 
neral pubescence. Umbels in our specimen 3-5-flowered, 
capitately contracted, with an involucre or ruffle of lanceo- 
Jate leaflets: common peduncle thick, shorter than the pe- 
tioles, pedicles about the length of the calyx, separated by 
narrow bractes. Flowers greenish yellow, about an inch in 
diameter. Calyx equal to the faux, campanulate, villous, 
of five ovately lanceolate leaflets. Corolla coriaceous, urceo 
Jately rotate with darker veins, smooth, opaque on the 
inside, shining without; limb fiatly extended, five-parted 
to below the middle, segments rounded: faux short, urceo- 
lately tubular: stamineous crown light purple, grown to the 
bottom of the faux, of five squarish scutiform contiguous 
laminz which ascend without adhesion along the wall of 
the faux to a little above its orifice, and are repand at the 
upper margin with a very faint triple indentation. Sta- 
mineous column equal to the crown. Stigma depressed, 
whitish. 
а The calyx. 5 Corolla, с Stamineous crown detached from the faux. 
d One pair of the pollen-masses, as they appear when suspended from the 
proper appendicle of the stigma.
