xi, c, i Merrill: Plants from Sorsogon Province, Luzon 17 



Among the Philippine species with pinnate leaves this one is well 

 characterized by its rather small, entire leaflets, its very large, brown- 

 pubescent panicles, and sessile flowers.

TRICHOSPERMUM Blume 



TRICHOSPERMUM ERIOPODUM (Turcz.) comb. nov. 



Grewia eriopoda Turcz. in Bull. Soc. Nat. Mosc. 31 ' (1858) 231;

Samab, Cuming 1680 (type number). Luzon, Province of Sorsogon, 

 Bulusan Volcano, Bur. Sci. 28658 Ramos, September 6, 1915. 



This species was described from flowering specimens collected in about 

 the year 1838, and has not appeared in our recent collections until the 

 year 1915, when Ramos discovered it in Sorsogon Province. The recently 

 collected material is in fruit, which enables me definitely to remove the 

 species from Grewia and transfer it to Trichospermum. The capsules are 

 2-valved, somewhat compressed, about 2 cm wide and 1 cm long, very 

 broadly ovoid or somewhat reniform, slightly apiculate, clothed with long, 

 brownish, shining, soft hairs. The species is very closely allied to Trichos- 

 permum leytense Merr., the latter being distinguished especially by its 

 somewhat pubescent leaves.
