450 ACANTHACEiE. 



2-lipped. Stamens didynamous i anther-cells diverging-pendulous. Ovary 2-eelled. Stigma 

 2-lamellate. Capable " elliptical, pointed at both ends : seeds imbricate, winged at both sides." 

 — Shrubby climbers ; leaves opposite, %-i-foliolate ; flowers in terminal racemes ; peduncles 

 often Z-S-jm. 



' 35. A. pauiculatniu, KtA. Scaly with minute points; rusty down on the angles of 

 the branohlets and petioles, and on the leaflet-ribs beneath, stellate none ; leaflets 3, ovate, 

 pointleted; corolla " whitish-blue." — Jacq. Amer. Pict. ^.175. — Bignonia, Jacq. — Hab, 

 Dominica !, imc. ; [Guadeloupe !, Mexico to Peru !]. 



11. ADBNOCALYMNA, Mart. 



Character of Bignonia, but capsule cylindrical, woody, and seeds wingless. — Shrubby 

 climbers ; leaves ^S-foliolate ; calyx usually glandular below the margin. 



The fruit of the West Indian species is unknown to me, but perhaps the woody, cylin- 

 drical capsule, described from a Jamaica specimen in the British Museum by Miers (Ann. 

 Nat, Hist. iii. 7. p. 167) may belong to its for though he referred that fruit to Tancecium, 

 it disagrees with Sloane's'description of the latter genus. 



36. A. alliacea, Mrs. Glabrous ; leaflets 3, large, elliptical ; corymbs axillaiy, few- 

 flowered, exceeded by the leaves ; calyx truncate or minutely 5'denticulate : glands obsolete ; 

 corolla white ; narrow part of the tube much longer than the calyx. — Bignonia, Lam., Sm. 

 — Leaflets 8"-4", calyx 3'", corolla 3"-3" long. — Hab. West Indies (Sw.), probably Jamaica ; 

 [Haiti 1; Guiana!]. , 



13; TAN^ClUM, Sw, 



Calyx oampanulate, closed in the bud. Corolla infundibular : tube elongated, filiform- 

 clavate. Stamens didynamous ; anther-cells diverging. Ovary 3-celled, Stigma 2-lamel- 

 late. " J^wHndehisoent, pulpy ; seeds wingless." — Shrubby climbers ; leaves 2-3^o/JoW«; 

 flowers corymbose ; corolla wholly or on the lobes powdery-puberulous. 



The character of the fi-uit is taken from Sloane and Swarta i from Miers's recent obser- 

 vations (I. c. iii. 8. p. 116) it would appear, that the fruit is a capsule, analogous to that of 

 Adenocalymna, a statement not compatible with the descriptions of the authors quoted 

 below. 



27. T. Jaroba, Sw. Leaflets membranaceous-chartaceous, ovate or elliptical, with a 

 bluntish point, glabrous ; corymbs axillary, few-flowered j calyx tubular-campanulate, sub- 

 truncate ; corolla white, wholly puberulous ; lobes ovale, blunt, undulate ; 8 anthers 

 exserted ; style as long as the tube. — Sw. Ft. t. 30./. 1 : the flower. — T. albiftorum, BO. 

 —Pith of the branches cylindrical ; leaflets 5"-3", calyx 5"'-8"', corolla 6"-8" long ; 

 " berry exactly like a calabash, only smaller " (5^.), "oblong, 1' long" (/Sw.). — Hab. Ja- 

 maica !, Bist., March, Wullschl. ; [Guiana !, Brazil 1], 



38. T. crucigerum, Seem. ! Leaflets leathery, oval, glabrous ; racemes few-flowered, 

 axillary and terminal ; calyi tubular'campanulate, snbtrunCate ; corolla wholly pubei-ulous : 

 lobes deltoid, pointed, undulate ; 2 anthers exserted ; style as long as the tube. — Plum. Bd. 

 Burm. t. 58.— Bignonia L. Pith of the branches cross-shaped ; leaflets 3"-*4", calyx 6'", 

 corolla 6"-7" long. — Hab. Dominica !, Imr., S. Vincent I, Guild. 



39. T. exsertunt, Gr. {n. sp). Leaflets membranaceous, ovate or oval, blunts glabrous; 

 corymbs many-flowered; Calyx tubular-campanulate, 5-mucronulate-truncate; cOroWa wholly 

 puberulous : lobes ovate-oblong, bluntish, undulate ; 3 anthers shortly exserted ; style long- 

 exsCrled.-—Com'ib, half as long as. in the two preceding species. Leaves 4"-3", calyx 6'"; 

 corolla 4"-3"j style 5"-4" long.— Hab. Jamaica !, March, 



CXV. ACANTHACE^.
