 stoma, a mouth ; in allusion to the wide mouth of the flower.) 

 D. Don, in edinb. phil. journ. 1823. Bignonia species of Pav. 



LIN. SYST. Didynamia, Angiosperma. 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 aarnog, asteios, beautiful ; and 

 ctvSoe, anthos, a flower ; in allusion to the brilliant flowers.) D. 

 Don, in edinb. phil. journ. 1823. 



LIN. SYST. Didynamia, Angiosperma. 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 purpurea, reddish purple. Lobes of 

 the limb of the corolla broad, round, with curled and erose 

 edges. This genus is distinguished from Bignonia, in the con- 

 fluent lobes of the anthers, by its seeds being furnished with 

 a villous pappous, and by its habit. It differs from Tecoma, 

 besides the characters above enumerated, in having a parallel, 



and not a transverse dissepiment ; and from Spathbdea, 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.

 resemblance ; on account of the calyx being furnished with a 

 distinct lip.) D. Don, in edinb. phil. journ. 1823. Bignonia 

 species, Cav. 



LIN. SYST. Didynamia, Angiosperma. 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 Chelone. This is a well- 

 marked genus, readily distinguished from Spathbdea, in the 

 structure of its capsule, and by having simple, alternate leaves.
