sulcate ones; in both we have entirely glabrous to very pubescent 
species. While many authors have recognized Grumilea as a 
valid genus, most recent botanists have followed Bentham & 
Hooker f. in placing the species with ruminated seeds under 
Psychotria. K. Schumann,‘ however, has retained Gaertner’s 
genus, and has described many African and Malayan species. 
He has been followed by S. Moore, Hiern, Krause, and to a less 
degree by Valeton. Examination of the seed characters of our 
Philippine forms has shown that the bulk of our species that 
have previously been referred to Psychotria are in reality re- 
ferable to Grumilea, and it is suspected that a high percentage 
of the Malayan species are Grumilea rather than Psychotria. 
While I have examined all of our rather abundant Malayan 
material, I am at present concerned only with those forms that 
are found in the Philippines. Below is given a list of those 
species, described under Psychotria, which are definitely refer- 
able to Grumilea, followed by the descriptions of a few ap- 
parently undescribed forms. 
GRUMILEA ARBORESCENS (Elm.) comb. nov. 
Psychotria arborescens Elm. Leafl. Philip. Bot. 3 (1911) 1080. 
MINDANAO, Elmer 11263. 
This species is apparently very closely allied to Psychotria celebica Miq. 
GRUMILEA URDANETENSIS (Elm.) comb. nov. 
Psychotria urdanetensis Elm. Leafl. Philip. Bot. 5 (1913) 1983. 
MINDANAO, Elmer 13708. 
GRUMILEA RIZALENSIS (Merr.) comb. nov. 
Psychotria rizalensis Merr. in Philip. Journ. Sci. 8 (1912) Bot. 57. 
Luzon, Loher 6845, 6405. 
GRUMILEA MICROPHYLLA (Elm.) comb. nov. 
Psychotria microphylla Elm. Leafi. Philip. Bot. 2 (1908) 522. 
NeGros, Elmer 9505, 10191. PALAWAN, Bur. Sci. 705 Foxworthy. 
GRUMILEA VERSICOLOR (Elm.) comb. nov. 
Psychotria versicolor Elm. Leafl. Philip. Bot. 4 (1912) 1852. 
PALAWAN, Elmer 12768. MINDANAO, Elmer 13740 (as P. luzonensis). 
TINAGO, Ahern 472. 
Valeton cites Ahern 472, and Elmer 8200 (err. 82000) sub Psychotria 
aurantiaca Bl., with doubt; cfr. Ic. Bogor. 3: 227, but I do not think that 
Ahern 472 can be so referred, although Blume’s species is a Grumilea. 
GRUMILEA MINDANAENSIS (Merr.) comb. nov. 
Psychotria mindanaensis Merr. in Philip. Journ. Sci. 8 (1913) Bot. 54. 
MINDANAO, Merrill 8084, 8096. 
‘Engl. & Prantl. Nat. Pflanzenfam. 4* (1891) 115.
