up two distinct though very closely allied species of this genus, but 

 which the possession of more perfect materials now enables me to define 

 satisfactorily. As regards the foliage of the two species, the slightest 

 diflference can scarcely be detected, but the following characters^ derived 

 from the flowers, show them to be abundantly distinct : 



1. Prosorus indica^ Dalz., Hook. Journ. of Bot. vol. iv. p. 345 ; Thw. 

 loc. cit. vol vi. p. 298. t. 10. a fig. 3, 4, 5, 6, C.P, No. 3099, c?. 

 No. 2155, ? , in Herbario Peradeniensi. — FL mas, numerosissimi, 

 1-^ lin. lati ; disco convexo, gibbo, ruguloso ; pedicellis 3-4 lin. longis, 

 Fl-fcem, terni; pedicellis 4—5 lin. longis. 



Not uncommon in the southern and central parts of the Island, at 

 no great elevation. — The native name is ^^ Carrou-gassj'^ 



2. Prosorus Gcertneri^ Thw. P. indica, Thw. loc. cit. Jiff. 1, 3, 7, 8, 

 9, 10. Croton? cyanospermum, Gcertnery Be Fruct, vol. ii. p. 130. 

 /. C. 7, C.P. No. 2601 in Herbario Peradeniensi.— J'Z. mas, numerosi, 

 3 lin. lati ; disco concavo, Isevi, cum calycis tubo adnato ; pedicelhs 

 4-5 lin. longis. Fl.fosm. solitarii; pedicellis 5-8 lin. longis. 



This differs from the preceding species in having larger and less nu- 

 merous flowers and longer pedicels, and in the shape of the glandular 

 disc in the male flowers. It occurs at an elevation of 500 to 1000 

 feet in the Ambagamowa and Eatnapoora districts. — The native name 

 is '^ SooddoO'leyang-gass.^^ .
