ArtsToLocHta macradenia ; scandens glaberrima, foliis sublonge petiolatis cor- 
dato-hastatis, sinu profundo lato lobis rotundatis, pedunculo axillari soli- 
tario unifloro petiolo sublongiore, perianthii unilabiati tubo basi inflato

magnis globosis stipitatis. 
This curious plant flowered, im a warm greenhouse of the 
Royal Gardens of Kew, in the spring of 1849, and there our 
drawing was made. It had bloomed the year before with John 
Taylor, Esq., of Sheffield House, Kensington, to whom we 
are indebted for the possession of the plant. That gentleman 
imported it from Real del Monte. It is one of the most re- 
markable and distinct of the many species of the genus. 
Dezscr. Cultivated in a pot, with a balloon trellis, this forms 
a suffruticose, climbing plant, with long, slender, terete stems. 
Leaves alternate, four to five inches long, petiolate, between 
cordate and hastate, tapering to an acute point, glabrous, with 
about seven principal nerves and several connecting nervelets, 
the sinus deep and broad, the lobes large, rotundate, spreading. 
_ Petiole about an inch and a half long. Peduncle longer than 
the petiole, axillary, solitary, single-flowered. Flower rather 
large, somewhat drooping, including the germen, almost as long 
as the leaves. Ovary slightly downy, inferior, club-shaped, 
furrowed. ude greenish, striated, the lower half much inflated, 
then contracted, at the summit again dilated and extending into 
a single declined, large, ovate Jip, the sides always revolute, the 
upper surface rich brown, with yellow reticulated veins, and 
beset with large stipitate, globose glands, looking almost like the 
fructification of some Calicium. The tube inside is slightly hairy, 
and there is a scale at the summit of the inflation. Co/wmn oval, 
SEPTEMBER lst, 1849.
