THE DICTIONARY 
OF GARDENING, 
PITCHER. A name commonly applied to the tubular 
petioles of the Sarracenias, and also to the urn-like ex- 
pansion in Nepenthes. Sir Joseph Hooker has shown 
that, in the latter genus, the Pitcher is not the dilated 
petiole, but a special organ, represented by a gland at 
the top of the costa of the young leaf.

genus comprising about a score species of stove, often 
tomentose-pubescent or lepidoted, sometimes glabrous, 
climbing shrubs, natives of tropical America, extending 
from Brazil to Mexico, Flowers white or violet, rather 
large, disposed in simple, or rarely sub-thyrsoid, branched 
racemes; calyx broadly tubular-campanulate, truncate or . 
minutely five-toothed ; corolla tube cylindrical and enlarged 
above the base, often incurved ; limb sub-bilabiate; lobes 
five, round, spreading. Leaves opposite, trifoliolate, or 
with the terminal leaflet changing to a tendril, or defi- 
ciently bifoliolate; leaflets entire, petiolulate. Very few 
species are now grown. For culture, see Bignonia.

l, conjugate ; leaflets cordate, acuminate, slightly pubescent, 
h. 10ft. Plant slender, glabrous, (B, R. 1844, 54, under name of 
Bignonia Caroline.) 
PITHECOLOBIUM (from pithecos, an ape, and 
Tobos, the lobe of the ear; in allusion to the native name, 
shaped; peduncles solitary or sub-fasciculate, _ 
axillary or racemose, or fasciculate at the tips — 
of the branches; heads globose, or rarely in 
oblong or almost cylindrical spikes. Pods com- 
pressed or flat, either spirally twisted or much 
mrved, bivalved or rarely indehiscent. Leaves 
bipinnate ; leaflets sometimes small and many- 
jugate, sometimes large and few-jugate, occa- 
sionally tergeminate, bigeminate, or geminate 
(pinne one-jugate, three, two, or one-foliolate) ; 
_stipules sometimes small or inconspicuous, 
sometimes persistent, hard or spinescent. Few 
of the species have been introduced. For cul-
