Sea-shore at Palisadoes Plantation, Jamaica. 



The fruit and seeds of this are rather smaller than those of Carapa moluccensis, and 

 although the seeds are not albuminous, the large embryo is very oily. This species 

 inhabits the West Indies, Central America, and Eastern Tr.opical South America, mostly 

 crowing in maritime districts. 



ANACARDIACE.E. 

 Spondias sp. 



Sea-shore at Palisadoes Plantation, Jamaica. 



This is probably the Hog-plum [Spondias lutea, Linn.), which is common, both wild 

 and cultivated, in many parts of Tropical America and the West Indies, and also on the 

 western coast of Tropical Africa. The fruit is drupaceous, with a bony endocarp. 



LEGUMINOStB. 

 Mucuna urens, DC. 



Mueuna urens, DC. ; Griseb., Fl. Brit. W. InJ., p. IDS; Oliver, Fl. Trop. Afr., ii. p. 185 ; Mann in

Sea-shore at Palisadoes Plantation, Jamaica. 



This species is widely dispersed in Tropical America, yet Grisebach states that it is 

 uncommon in Jamaica; it is also recorded from the Sandwich and Marquesas Islands; 

 and there are specimens in the Kew Herbarium from various points on the western coast 

 of Tropical Africa. We have seen no Polynesian specimens, but there seems no reason to 

 doubt the records, for the species is easily distinguished. Jouan states that he found a 

 few plants of it in the island of Hiwaoa, Marquesas, but he never saw it in Nukahiva. 



Mucuna pruriens, DC. 



Mueuna pruriens, DC; Griseb., Fl. Brit. W. Ind., p. 198; Oliver, Fl. Trop. Afr., ii. p. 1S7 ; Seem., 

 Fl. Vit., p. 59 ; Foist., Fl. Ins. Austr. Prodi., p. 50. 



Sea-shore at Palisadoes Plantation, Jamaica. 



This is one of the Leo-uminosse sometimes washed ashore on the western coast of 

 Europe. It is much more widely dispersed than Mucuna urens, though hitherto it has 

 neither been found in Australia, nor in Polynesia, so far as we are aware ; and Seemann 

 states that there is no specimen or drawing in the British Museum of the plant from the 

 Tongan Islands named " Dolichos pruriens, Linn. ?" by Forster.
