 tubercles. Leaves ovate, acute. Corolla red, ending in long 

 tail each.

 rambling. 



2 S. LAURIFOLICS (D. C. 1. c. Desf. 1. c. p. 411.) erect; 

 leaves opposite, and 3 in a whorl ; flowers glomerate, terminal 

 and lateral, rising after the leaves have fallen. (? . S. Native 

 of Sierra Leone, by the sea side. We have seen this species 

 growing by the sea side, near Cape Shilling, where it forms a 

 bush, about 6 or 8 feet high, covered with blossoms, before the 

 leaves rise. Flowers red and white. Very nearly allied to 

 S. sarmentosus, but the stems are erect, and the corollas less 

 spreading.

 -.le, ovate-lanceolate, glabrous ; peduncles terminal, few- 

 flowered, becoming lateral, or in the forks of the branches ; 

 tails of the segments of the corolla ensiform ; stamens inserted in 

 the base of the tube, fj . E. Native of China. Nerium Chi- 

 nensis, Hunter, in Roxb. fl. ind. 2. p. 9. S. divergens, Graham ? 

 S. dichotomus, Ker. bot. reg. 469 ? Dr. Roxburgh could not 

 find any scales in the tube of the corolla.

 scandent ; peduncles terminal, many-flowered ; leaves ovate- 

 oblong, a little acuminated, glabrous ; tails of the segments of 

 the corolla long. Ij . ^. S. Native of Cochinchina, among 

 bushes. Nerium scandens, Lour. coch. p. 116. Calyx tubular, 

 with fleshy, erect segments. Corolla funnel-shaped ; having 

 the lower part of the tube cylindrical, and the superior part ur-

 repand. Corona of the tube of many acute segments; anthers 

 ending in a long, thread-like tail, each. Follicles thick, obtuse, 

 horizontal. 



Climbing Strophanthus. Shrub cl. 



8 S. ALTERMFLORUS (Spreng. syst. 1. p. 637.) scandent;

 rous. 17.^.6. Native of China, in small islands near Canton. 

 Apocynum alterniflorum, Lour. coch. 168. Flowers pale. Co-

9 S. nisriDA (D. C. 1. c. Desf. 1. c. p. 412.) corollas funnel- 

 shaped : with long, acuminated segments ; anthers acute. Ij . S. 

 Native of Sierra Leone. Shrub hispid, almost with the habit of 

 a Justicia. Leaves sessile, ovate-oblong. Flowers fasciculate, 

 on peduncles, which are repeatedly trichotomous. Corollas red : 

 having the tails of the segments 7 inches long. 



Hispid Strophanthus. Shrub. 



Cult. Shrubs of easy culture. A mixture of peat, loam, and 

 sand, is the best soil for them ; and cuttings strike root readily 

 in sand, under a hand glass, in heat. The species are worth cul- 

 tivating for the singularity as well as beauty of their flowers. 



Tribe II. 



WRIGHTIFJE. Fruit of 2 follicles. Tuft of hairs at die 

 lower end of the seed, or at that end contrary to the umbilicus. 

 Embryo with involute cotyledons. 



XXIV. WRIGHTIA (named after the late William Wright, 

 M.D. F.R.S. F.L.S. and Edinb., whose ardour in the pursuit of 

 botanical knowledge, even while engaged in extensive medical 

 practice in the island of Jamaica, has long entitled him to this 

 mark of distinction.) R. Br. in mem. wern. soc. 1. p. 73. 

 Nerium species, Lin. 



LIN. SYST. Pentdndria, Monogynia. Calyx 5-parted. Co- 

 rolla salver-shaped; throat crowned by 10 divided scales. Sta- 

 mens exserted ; filaments inserted in the throat ; anthers sagittate, 

 cohering by their middle to the stigma. Ovaria 2, cohering. 

 Style 1 , filiform, dilated at top ; stigma narrower. Scales 5- 10, 

 inserted at the base of the calyx, outside the corolla. Follicles 

 distinct or combined, with adnate placentas. Erect shrubs, or 

 small trees. Leaves opposite. Corymbs almost terminal. 

 Flowers white. Albumen none. Cotyledons longitudinally in- 

 volute, white, but immersed in hot water they become rose- 

 coloured. 



1 W. AXTIDYSESTE'RICA (R. Br. 1. c. p. 74.) leaves obovate- 

 oblong, short-acuminated, glabrous ; corymbs nearly terminal ; 

 tube of corolla 6 times longer than the calyx ; follicles distinct.

 47. ? Flowers white, sweet-scented, form of a species of Jasmi- 

 num. The wood being white, of a fine grain, is useful for the 

 turner, and to make cabinets, and other elegant furniture. The 

 bark is reputed to be a specific in dysentery, and most complaints 

 of the bowels, and is the Conessi bark of the Materia Medica. 



Anti-dysenteric Wrightia. Clt. 1778. Shrub 6 to 10 feet. 



2 W. ZEYLA'XICA (R. Br. 1. c.) leaves oblong-lanceolate, 

 sub-acuminated, glabrous ; corymbs terminal ; tube of corolla 

 4-5 times longer than the calyx ; follicles distinct. I? . S. Native 

 of Ceylon. Nerium Zeylanicum, Lin. amcen. acad. 4. p. 309. 

 Burm. zeyl. 23. t. 12. f. 2. W. divaricata, Herb. madr. Very 

 nearly allied to W. antidyscnterica, from which it differs, in the 

 figure of the leaves, which are also rather smaller.
