450 ACANTHACEJ3. 



2-lipped. Stamens didynamous : anther-cells diverging-pendulous. Ovary 2-celled. Stigma 

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

 — Shrubby climbers; leaves opposite, 2-Z-foliolate ; flowers in terminal racemes; peduncles 

 often 2-3-fid. 



25. A. paniculatum, Kth. Scaly with minute points; rusty down on the angles of 

 the branchlets and petioles, and on the leaflet-ribs beneath, stellate none ; leaflets 2, ovate, 

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

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



11. ADENOCALYMNA, Mart. 



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

 climbers ; leaves 2-i-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 Miei's {Ann. 

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

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



26. A. alliacea, Mrs. Glabrous ; leaflets 2, large, elliptical ; corymbs axillary, 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., Su>. 

 —Leaflets 8"-4", calyx 3'", corolla 2"-3" long.— Hab. West Indies (Sw.), probably Jamaica ; 

 [Haiti!; Guiaua !]. 



12, TAN^CIUM, Sw. 



Calyx campanulate, closed in the bnd. Corolla infundibular : tube elongated, filiform- 

 clavate. Stamens didyuamous : anther-cells diverging. Ovary 2-celled, Stigma 2-lamel- 

 late. " Fruit indehiscent, pulpy ; seeds wingless." — Shrubby climbers ; leaves 2-i-foliolate; 

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



The character of the fruit is taken from Sloane and Swartz : 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-chartaceons, ovate or elliptical, with a 

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

 truncate ; corolla white, wholly puberulous : lobes ovate, blunt, undulate ; 2 anthers 

 exserted ; style as long as the tube. — Sw. Fl. t. 20. /. 1 : the flower. — T. albiflorum, DC 

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

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

 maica!, Dist., March, Wullschl. ; [Guiana!, Brazil!]. 



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

 axillary and terminal ; calyx tubular-campanulate, subtruncate ; Corolla wholly puberulous : 

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

 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 !, Guild. 



29. T. exsertum, Gr. (n. sp). Leaflets membranaceous, ovate or oval, blunt, glabrous ; 

 corymbs many-flowered ; calyx tubular-campanulate, 5-mucronulate-truncate; corolla wholly 

 pubendous : lobes ovate-oblong, bluntish, undulate ; 2 anthers shortly exserted ; style long- 

 ezserled. — Corolla half as long as in the two preceding species. Leaves 4"-8", calyx 6 , 

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



CXV. A.CANTHACE.E. 



Stamens inserted into the sympetalous, usually 2-lipped corolla, didynamous or two. 

 Ovary superior, mostly syncarpous, 2-cclled : ovules along the axis, usually definite, ascend- 

 ing, Fruit mostly capsular, elaslically locnlicide : dissepiment usually 2-partite, often bearing 

 hooked appendages (the retiiiacula) along the margin of each seed- Embryo exalbuminous.
