solid as ivory. From these kernels are manufactured the 

 toys, knobs, &c., which are whiter than animal ivory, and 

 equally hard if not put under water ; if they are, they be- 

 come white, and hard again when dried. 



Both the male and female plants have been introduced to 

 Europe, and each have flowered ; the male at Schonbrun, 

 and the female at Kew, both in 1855. Their immense leaves 

 render them ornamental objects in the palm-house. (Bot. 

 Mag., 1856, pi. 4913 and 4914, for May.) 



326. CoFFEA Benghale'nsis Roxh. Bengal Coffee. (Ara- 



biaceas.) India. 



A hothouse plant ; growin? three fe^t high; with white flowers; appearing in spring; increased 

 by cuttings ; grown in light rich soil. Bot. Mag., i85li, pi. 4917. 



A beautiful species of the real coffee of Arabia, of inferior 

 quality for its fruit, but conspicuous for the number and 

 beauty of its white flowers. It has a foliage similar to the 

 Coff'ee plant, and flowers resembling somewhat the Single 

 Cape jasmine, but larger, and produced in far greater profu- 

 sion. It is a pretty addition to hothouse collections. [Bot. 

 Mag., May.) 



327. Perne'ttya fu^rens Klotzsch. Maddening Pernet- 



TYA. (Ericaceae.) Chili. 



A half-hardy evergreen shrub; growing two feet high; with white flowers; appearing in 

 spring; increased by layers and cuttings ; grown in heath soil. Bot. Mag. 1856, pi. 4920. 



A beautiful shrub, with light foliage, producing dense ra- 

 cemes of white, waxy, heath-like flowers, which appear in 

 March in the open ground in England. With us it would 

 probably require the protection of the greenhouse or frame, 

 as it is a Chilian plant. The leaves are small, ovate and ser- 

 rated. (Bot. Mag., June.) 



328. Aristolochia Thwa'itesii Hooker. Mr. Thwaite's 



Aristolochia. (Aristolochiacese.) Ceylon. 



A hothouse plant ; growing six inches high; with yellowish flowers; appearing in spring; in- 

 creased by cuttings; grown in leaf mould, peat and sand. Bot. Mag., 1856, pi. 4918. 



A remarkable species of the curious Aristolochia, or Dutch- 

 man's pipe, with a tuberous stem, from which fleshy roots 

 are emitted, and bearing above, a cluster of several erect
