Letti. — This species is a favourite cultivated plant in the tropics on account of the 

 delightful fragrance of its flowers ; and it also exists in a wild state in nearly all warm 

 countries. Eespecting its distribution, Mr Bentharn, loc. cit., says : " Widely spread 

 over the tropical and subtropical regions of the New and the Old World, but so generally 

 cultivated for the perfume of its flowers, and so frequently established as an escape from 

 cultivation, that it is difficult to determine where it is really indigenous. It appears, how- 

 ever, to be so in Western America, from Northern Chili to Texas, not, perhaps, in Brazil 

 nor in Guiana ; abundant in tropical and subtropical Northern-Central Australia, and in the 

 interior of North-Eastern Australia, and perhaps also really indigenous in Tropical South 

 Africa, but introduced only into the East Indies, Northern Tropical Africa, and the Medi- 

 terranean region." Jouan (in Mem. Soc. Sci. Nat. Cherbourg, xi., 1865, p. 107) and H. 

 Mann (in Proc. Amer. Acad., vii. p. 1G5), both treat it as certaiuly introduced in Eastern 

 Polynesia. 



Acacia numbers nearly 450 species, generally spread over the warmer parts of the 

 world, but most numerous in Australia and Africa ; in the former there are nearly 300, 

 and, with the single exception of Acacia farnesiana, they are endemic. 



ROSACEA. 

 Parinarium sp. 



Wettee. — Parinarium is a genus of about forty arboreous species, generally spread in 

 tropical countries ; the seed-vessel has a hard woody endocarp. 



Rubus glomeratus, Blume. 



Rubus glomeratus, Blume; Miq., Fl. Ind. Bat., i. 1, p. 381 ; Hook, f., El. Brit. Ind., ii. p. 328. 

 Dammar. — Also found in Java, Borneo, the Philippines, and in Penang. This is allied 

 to the very variable Rubus moluccanus, which is exceedingly common and generally spread 

 in Tropical Asia. Genus very widely dispersed, though very few species are found in south 

 temperate regions. 



CRASSULACEiE. 



Bryophyllum calycinum, Salisb. 



Bryophyllum calycinum, Salisb. ; Hook, f., Fl. Brit. Ind., ii. p. 413 ; Oliver, Fl. Trop. Afr., ii. p. 390. 



Ki ; Timor Laut. — This plant is now very widely dispersed in tropical and sub- 

 tropical countries, except Australia, but it is probable that it is only indigenous in Africa. 

 It has been carried from place to place as a curiosity, from the fact that a very small
