valves. Seeds flat, transverse, with membranous margins.—

those of the sweet chestnut, elliptic, coriaceous, acute, feather- 
nerved, petiolate, with serrated edges, clothed with copious 
stellate tomentum beneath, 5-7 inches long, and 2-3 broad, gla- 
brous above. Flowers terminal, numerous, spicately panicled, 
reddish purple, size of those of Jacaránda. Style slender,

D. Don, in edinb. phil. journ. 1823.—Bignónia species of Pav. 
Lin. syst. Didyndmia, 4ngiospérma. Calyx campanulate, 
3-lobed, coriaceous. Corolla funnel-shaped, with a dilated 
throat, and a spreading, bilabiate limb ; lower lip 3-lobed; 
upper lip shorter, and 2-lobed; lobes broad, roundish, 
flat. Stamens 4, didynamous, that is, 2 long and 2 short; 
with the addition of a short fifth sterile, glabrous one. 
Lobes of anthers parallel, equal. Stigma broad, bilamel- 
late. Capsule lanceolate, compressed, 2-celled; valves coria- 
ceous, rather fleshy : dissepiment parallel with the valves. Seeds 
flat, transverse, with broad, membranous edges.—Frondose 
trees, natives of Peru. Leaves simple, opposite, elliptic, pe- 
tiolate, bluntly acuminated. Flowers terminal, spicately race- 
mose, large, rose-coloured. The campanulate, 3-lobed calyx, 
the figure of a corolla; the parallel lobes of the anthers ; and 
the structure and form of the capsule; are the marks which par- 
ticularly characterize this genus.

XI. ASTIA'NTHUS (from aarevoc, asteios, beautiful; and 
av3oc, anthos, a flower ; in allusion to the brilliant flowers.) D. 
Don, in edinb. phil. journ. 1823. 
Lin. syst. Didynamia, Angiospérma. Calyx tubular; limb 
equal, 5-toothed. Corolla tubular at the base, but with a dilated, 
campanulate, ventricose throat; limb 5-lobed, bilabiate ; lower 
lip 3-lobed, the middle lobe large; the superior lip 2-lobed, and 
reflexed. Stamens 4, didynamous; with a shorter, glabrous 
rudiment of a fifth sterile one. Stigma bilamellate. Anthers 
naked ; lobes equal, confluent. Capsule very long, siliquose, 2- 
celled. Dissepiment parallel with the valves, thick, placentife- 
rous on both sides. Seeds transverse, compressed ; with winged 
margins, and pappose from numerous villi.— An erect, branched, 
frondose shrub, native of Mexico. Branches terete, glabrous. 
Leaves simple, tern, elongated, broad-linear, coriaceous, quite 
entire, glabrous, 6-10 inches long, 1-nerved, attenuated at both 
ends. Flowers terminal, numerous, panicled. Corolla larger 
than that of Digitalis purpürea, reddish purple. Lobes of 
the limb of the corolla broad, round, with curled and erose 
edges. This genus is distinguished from Bigndnia, in the con- 
fluent lobes of the anthers, by its seeds being furnished with 
a villous pappous, and by its habit. It differs from Técoma, 
besides the characters above enumerated, in having a parallel,

and not a transverse dissepiment; and from Spathddea, with 
some species of which it agrees in habit; but is readily distin- 
guished by the structure of its capsule, in having seeds furnished 
with a villous pappous, and lastly, in the lobes of the anthers 
being confluent.

XII. CHILO'PSIS (from xewoc, cheilos, a lip; and ow, ops, 
resemblance; on account of the calyx being furnished with a 
distinct lip.) D. Don, in edinb. phil. journ. 1823.—Bignonia 
species, Cav. 
Lin. syst. Didyndmia, Angiospérma. Calyx membranous, 
oblong, ventricose, cleft on the lower side, even to the base; 
limb oblique, tridentate on the upper side. Corolla with a 
tubular base, and a dilated campanulate throat; limb 5-lobed, 
bilabiate ; lobes oval-roundish, with curled, crenated edges ; 
lower lobe large, oblong. Stamens 4, didynamous ; besides the 
rudiment of a fifth sterile, glabrous one. Stigma bilamellate. 
Anthers naked; lobes equal, divaricate. Capsule short, sili- 
quose, 2-celled: dissepiment contrary, placentiferous. Seeds 
transverse, with membranous margins.—An erect, branched 
shrub, native of Mexico; with terete, downy branches. 
Leaves alternate, linear, flat, elongated, 3-5 inches long, 
glabrous, coriaceous, attenuated at both ends. Racemes ter- 
minal, short, dense, tomentose; pedicels short, furnished with 
2 linear-lanceolate bracteoles each. Lobes of stigma replicate. 
Corolla dark purple, size of those of Cheldne. This is a well- 
marked genus, readily distinguished from Spathddea, in the 
structure of its capsule, and by having simple, alternate leaves.
