DESCRIPTIVE LIST OF NEW PLANTS. 
neria faucialis and the G. Suttoni should be united with G. bul- 
bosa, which is evidently a highly variable plant, and one that has 
apparently an extensive geographical range, extending from Brazil 
to New Grenada. In the latter country, about Santa Martha 
the present singular variety of this species, for such I take it to 
be, was detected and sent to Kew by our collector, Mr. Purdie. 
It first produced its blossoms, &c., at Sion House, under the 
skilful management of Mr. Carton. At first sight it is distin¬ 
guished from the true G. bulbosa by its pale brick-coloured 
flowers and by the drooping racemes. The arrangement of these 
flowers, in the raceme, on simple pedicles, would rather induce 
me to refer this to G. faucialis than to bulbosa , could I persuade 
myself they are really distinct; but, as far as I can find, the 
leaves and flowers are alike in both, and the only difference dis¬ 
cernible is in the large and more divided raceme or panicle of 
the true G. bulbosa. — Bot. Mag. 4240. 
Gesneria elliptica , var. lutea. Another of the results of Mr. 
Purdie’s mission to the mountains of St. Martha, New Grenada. 
The flowers of this species, however, exhibit much variation in 
hue; and we have chosen the most unusual of these colours in 
the genus, namely, the yellow. Others are brick-coloured, and 
some bright red; all are graceful in their growth, and handsome 
in their flowers. As a species it will rank near G. rutila, and 
especially that variety of it called A. atrosanguinea ; but the 
shape of the upper part of the corolla and the relative size of 
the lips afford distinguishing characters. It flowers in a warm 
moist stove in May, and through most of the summer months.—

Bromeltace^e. —Hexandria Monogynia. 
Pitcairnia undulatifolia. A native, probably, of Brazil; but 
of the history of which we know nothing, save that it was sent to 
the Royal Gardens of Kew, from Liverpool, by our obliging- 
friend, Mr. Shepherd, under the name here adopted. It is a 
very showy plant, and no stove collection should be without it. 
The leaves are handsome, and of a light green; the lower brac- 
teas are furfuraceous below, red, tipped with green, and the long, 
protruding corollas are quite white. It flowers in May, and easily 
bears parting at the root.— Bot. Mag. 4241. 
Gentiane.e. —Pentandria Monogynia. 
Leianthus umbellatus. A rare and little known species, hand-
