 shoots.

 Cult. For culture and propagation see Dischidia, above. 



XXXIV. TRIPLOSPE'RMA (rptrrXooe, Iriploos, triple; and 

 arTEp^a, sperma, a seed ; the seeds are disposed in 3 ranks or

 Stapelia Cochinchinensis, Lour. coch. 114. 



Cochinchina Triplosperma. Shrub creeping.

XXXV. HARRISO'NIA (named by Hooker, in compliment 

 to Mrs. Harrison, of jEgburgh, near Liverpool, who was the 

 first to introduce the plant from Brazil.) Hook, in bot. mag. 

 vol. 53. t. 2699. 



LIN. SYST. Pentandria, Digynia. Corolla urceolate, 5-toothed ; 

 with a naked throat. Stamineous corona. 5-leaved ; leaflets 

 simple at top, furnished with a fleshy scale or process inside. ? 

 An erect, glabrous shrub. Leaves opposite, decussate, be- 

 tween fleshy and coriaceous, 2-3 inches long, elliptic-cordate, 

 obtuse. Umbels pedunculate, terminal. Corollas fleshy, fine 

 red ; limb a little spreading. Hooker describes the pollen 

 masses as erect ; but we much doubt the correctness of this ; 

 but should it be so, it is a very remarkable genus among the 

 tribe of Asclepiadeous plants, in which the pollen masses are 

 erect, and the anthers terminated by a membrane.
