in 5’s, the pedicels are intermediate in length between those of the other two 
groups, and are nearer the type in thickness, the inflorescence is usually lax, the 
bases of the petals rather conform to the second type. 
The plants, in spite of very considerable individual variations, can not be 
distinguished by any vegetative characters. 
The collections which seem to conform to the first type are Cuming 1686, 1126 
(type), without definite locality, but supposed to be from the Island of Samar: 
Luzon, Province of Ilocos Sur, San Quintin, For. Bur. 5646 Klemme (fruiting; 
probably) : Province of Laguna, Los Banos, Elmer 8294-' Province of Tayabas 
(Infanta), Anoling, For. Bur. 6692 Kobbe ; between Casihan and Gumaca, For. 
Bur. 10262 Curran; Lucban, Elmer 9195, Atimonan, For. Bur. 6703 Kobbe: Prov- 
ince of Camarines, Mount Isarog, For. Bur. 10503 Curran ; Pasacao, Ahern IS: 
Ticao, For. Bur. 1087 Clark: and presumably the following sterile specimens 
from Tayabas Province; between Paete, Laguna, and Piapi, For. Bur. 10135 
Curran; Malicboi, Ritchie; between Dagutan and Pitogo, For. Bur. 10218 Curran. 
To the second type belong the following, all from Mindanao : District of Zam- 
boanga, Sax Biver, Williams 2196 ; Lake Lanao, Camp Keithley, three sheets, 
Mrs. Clemens, without number; Province of Misamis, Mount Malindang, For. 
Bur. 4692 Mearns & Hutchinson. 
The linking type includes the following; Mindanao, District of Cotabato, 
Balugu, For. Bur. 6559 Hutchinson ; Lake Lanao, Camp Keithley, Mrs. Clemens 
616 and 4 unnumbered sheets; District of Zamboanga, Tetuan, Ahern 376: 
Basilan, Isabela, For. Bur. 3958 Hutchinson, DeVore <£- Hoover 97; with only 
insular locality, Hallier. 
Two sheets, Whitford 1684, Aroroy, Masbate, and For. Bur. 7 403 Danao, 
Occidental Negros, are unfortunately sterile. 
The stamens in this species are always described as free. They also vary in 
this respect. In the extreme development there is a short but perfectly definite 
androgynophore at the summit of which arise the stamens followed by the stami- 
nodes with a very short-stalked ovary; but the ovarian stalk may be entirely 
wanting; more commonly the bases of the filaments form a tube 2.5 mm or more 
in length, sometimes they are entirely free to the base. I have failed to correlate 
these variations with the types noted above; they more probably indicate age. 
This staminal arrangement is very similar to that of Gretoia stylocarpa Warb., 
an even commoner Philippine plant, ranging from Benguet in northern Luzon 
to Davao in southern Mindanao. The latter is, however, a true Grewia, having- 
capitate cymes paniculately arranged, each head surrounded by sepaloid bracts 
and containing 3 or 4 flowers. The sepals are separate to the base, much 
exceeding the petals, the anthers are not confluent, and mature flowers show 
a short but definite gynophore, which is not evident in very young flowers. 
It is not contended that Diplodiscus should be united with Grewia, as the 
sepals in the former never split to the base, and the anthers are confluent, even 
in buds. 
Pierre 3 has reduced Diplodiscus to Brownlowia, but if the separating char- 
acters cited' in the Pflanzenfamilien hold good for the latter, it seems preferable 
to hold them apart.
