URCEOLA. 



very elastic, scentless, and possessing all the qualities of the best 

 samples of that substance. 



PLUMIEKIA. 



Calyx obtuse, very small, with 5 obsolete teeth. Corolla 

 funnel-shaped, with a long tube enlarging by degrees ; limb 

 5-parted, somewhat erect, with ovate-oblong, oblique segments. 

 Filaments on the middle of the tube; anthers converging. 

 Stigma double, acuminate, nearly sessile. Follicles long, acu- 

 minate, ventricose. Seeds numerous, oblong, with a large, ovate, 

 toothed membrane. — Small trees with succulent branches, and 

 showy fragrant flowers.

 — Jamaica and Surinam. 



Leaves ovate-oblong ; flower-stalks downy. Flowers very large, 

 fragrant, white outside, yellow inside, and stained with red at the ends 

 of the segments. — Milk excessively corrosive. 



1138. P. acutifolia Poir. enc. meth. suppl. ii. 667. — P. acu- 

 minata Ait. Kew. ed. 2. ii. 70. Bot. Reg. ii. t- 114. P. obtusa 

 Lour, cochinch. 117., not of Linn. (Rumph. iv. 85. t. 38.) — 

 Malay Archipelago, and Cochinchina. 



Leaves lanceolate, flat, acuminate. Flowers very fragrant, in com- 

 pact cymes. Corolla white with a yellow throat ; the segments linear- 

 oblong, obtuse. — The root is used as a cathartic in Java. 



1139. P. drastica Martius, is said to be a powerful Brazilian 

 purgative. 



CAMERARIA. 



Calyx 5-toothed. Corolla between funnel-shaped and hypo- 

 crateriform, with the segments of the limb oblique. Stamens 

 inserted in the tube ; anthers acuminate, converging, extended 

 at the point into a thread. Styles scarcely any. Follicles re- 

 flexed, lobed on each side at the base. Seeds roundish, obtusely 

 pointed, compressed. 



1140. C. latifolia Jacq. amer. 37. t. 182. f. 86. Bot. Repos. 

 t. 261. R. and S. iv ; 421. — Meadows in Jamaica, Cuba, and 

 St. Domingo. (Bastard Manchineel tree.) 



A tall elegant tree, with a branching head ; yielding a most copious 

 supply of white coagulable milk. Leaves roundish-ovate, cuspidate, 

 with parallel transverse streaks, very shining, rather stiff, stalked. 

 Peduncles 1-flowered or many-flowered, slender, long, axillary, or in 

 the forks of the twigs. Flowers white. — It is probable that this 

 plant, which is very abandant in Cuba, might prove a valuable source 

 of Caoutchouc, as the milk gushes out at the smallest wound, and 

 readily thickens. It is however said, I know not upon what authority, 

 to be so poisonous as to be used by the West Indian natives to en- 

 venom their arrows. Jacquin mentions nothing of it, and in Lunan's 

 compilation the juice is merely said to be acrid.
