Herbe alternifolie foliis pinnatis bipinnatifidisve: racemi terminalis laxi pedicellis tribracteatis. 
Rudimentum filamenti quinti (primum in Amphicome detectum a D, Royle). Genus Bignoniaceis 
adjiciendum, in sectione tamen propria ob habitum et semina pendula, radicula supera (v, Prodr. Flor. 
Nov-oll. 1. p. 471.) locandum et in duo subgenera dividendum. Horum alterum Incarvititea Juss.

loco membranaceis emarginatis ; seminibus obovatis margine lato membranaceo indiviso cinctis. 
Alterum, AmpuicomrE, (Cyrtandraceis quodammodo accedens) ex Indiz septentrionalis montibus ; 
foliis pinnatis foliolis incisis ; calyce 5-dentato sinubus ml aoe : seminibus fere subulatis utrinque

Incarvillea (Amphicome) arguta ; suffrutex, 3-pedalis, diffusa ; foliia sian: foliolis oppositis breve

(i) capsule with persistent style; (4) capsule ripened; (%) a portion of the same, with the dissepiment 
protruding, and of arounded form when covered with seeds, but is in direction opposite to the valves ;

~ This elegant species is the second of its genus, which has been found in the Himalayas, and has been 
drawn (from specimens brought me from Lower Kunawur) by Mr. Wilson Saunders, who has succeeded 
in giving a good general idea of the plant. It is most probably like the kindred species, J. Emodi, 
provided with a subterranean perennial stem, from which shoot the annual, striated, leafy stalks. 
Leaves alternate, petioled. Racemes long, few, or many-flowered, somewhat secund. Pedicels long, 
slender, with two or three small subulate bracts, more or less near to the flower, according to the 
elongation of the pedicel. Calyx tubular, pentagonal, angles stiffer than the membranous ciliate sides, 
terminating in 5-narrow subulate, slightly hairy teeth. Corolla hypogynous, monopetalous, irregular, 
tubular near the base, ventricose above, limb 5-lobed, lobes short, rounded, ciliate, imbricated in 
estivation. Stamens 4 didynamous inserted into tube of corolla, with the rudiment of a fifth stamen 
(not represented in the figure.) Anthers 2-lobed, lobes converging towards apex, one.a little longer 
than the other, each furnished about its middle with a small tail-like process, filament terminated above 
the anthers in a bruad membranous process. Germen oblong, with its base surrounded by a small 
cup-like disk. Style long, slender, persistent. Stigma composed of two thin lamellar plates. Capsule 
long, slender, silique-like, somewhat twisted when ripe, 2-valved, but the valves remain permanently 
united on one side, and open on the other, as in Wightia gigantea. Dissepiment thin, free, opposite 
to the valves, covered on both sides along the margins with suspended seeds, which are oblong, rough 
externally, slightly winged at both ends, and terminating in a much-divided coma of fine hairs. 
Embryo exalbuminous, straight, almond-like ; radicle above. Cotyledons foliaceous. 
123. ACANTHACEZ. 
As in several of the preceding, so in this family many of the species have a general 
resemblance to some of the Scrophularinee, though the order is more closely allied to 
Bignoniacee. This might be inferred from Blume having united the Cyrtandracee with 
the latter, while Bartling has placed them under Acanthace@. These are, however, 
distinguished from Bignoniacee by their seeds, though exalbuminous, being without 
wings. Resembling the last-named family in structure, they do so also in geographical 
distribution, for they are found in the equinoctial regions of both the Old and New 
_ World, with a few species extending north into the south of Europe, Pennsylvania, and 
Japan, and southwards to the Cape of Good Hope and the southern coast of New Holland. 
In India the Acanthacee are found every where in the plains, and also at considerable 
elevations in the mountains : the distribution of the genera, and even of some of the 
species,
