Liu. SYST. Pentdndria, Monogynia. Calyx 5-parted ; seg- 

 ments lanceolate-oblong, acute. Corolla funnel-shaped ; with 

 a narrow tube : and a swollen, large, inflated limb, which is 5-

 4-5 in a whorl, broad-oblong, acuminated, rusty beneath. I? . 

 S. Native of Guiana, Cayenne, Maranham, Surinam ; and in 

 the Island of Arrowabish, near Essequibo ; and on the banks of 

 the Orinoco, near Carichana. A. cathartica, Roem. et Schultes,

 rather hairy beneath, especially on the nerves, as well as the young 

 branches. Flowers large, yellow. We have seen this species 

 growing wild in Maranham; but it did not appear to us to be 

 in any way scandent.

6 A. VEETICII,LA V TA (Desf. tabl. de fecol. ed. 2d. p. 93. Pohl, 

 bras. 1. p. 75. Spreng. syst. 1. p. 584.) leaves usually 6 in a 

 whorl, ovate-oblong, obtuse, quite glabrous. J? . S. Native of 

 South America. Flowers large, yellow. 



If'horled-leaved Allamanda. Shrub. 



Cult. All the species of Allamanda, are worth cultivating, in 

 every collection of stove plants, for the sake of the beauty of 



12 



their large, yellow flowers, and whorls of showy foliage. A 

 mixture of loam, sand, and peat, is the best soil for them ; and 

 cuttings strike root freely in the same kind of earth, under a 

 hand glass, in heat. They require a strong, moist heat to make 

 them flower freely. 



LIX. ASPIDOSPEHMA (from a<nrtc ainrtooc, aspis aspidos,
