COMMELINACEAE. 
Four species were collected, all of wide Philippine distribution: Gommelina 
nudiflora Linn., 9215: Gyanotis capitata (Blume) C. B. Clarke, 690 4 : Forrestia 
philippinensis Merr., 6935, 10387: Pallia sumatrana Hassk., 9275. 
PONTEDERIACEAE. 
Represented by the common Monochoria vaginalis Presl, local name calabua; 
9022, 10338. 
LILIACEAE. 
Dracaena sp. 
This seems to be the species figured by Sarassin 2 under the name of It. 
multiflora Warb., to which I can find no other reference, and so believe to be still 
undescribed. The Celebes plants, found in different localities there, grew in 
similar situations to those of Polillo, arid coral-rocks; the habit is very much 
the same, except that the Celebes trees were larger and more widely branched 
than those of Polillo, but they were no larger than those from which Merrill 
5402, Ubian Island (Sulu Archipelago), was obtained. The latter can only be 
distinguished from the Polillo collection, 10407, by its slightly narrower leaves; 
not even this avails to separate Bur. Sci. 10635 McGregor, sterile, from Dalupiri, 
one of the Babuyanes Islands. D. rnaingayi Hook. f. is very closely allied, but 
its fruits are much larger. 
Other species: Dracaena angustifolia Roxb., 69.80, 10364': Dianella caerulea 
Sims, 9206, 1039J,. 
AMARYLLIDACEAE. 
Curculigo glabra Merr. in Philip. Journ. Sci. 2 (1907) Bot. 297. 
Otherwise known from Mindoro; 10366. 
Other species: Grinum asiaticum Linn., 9091, fairly frequent along the coast, 
local name bacon; G. zeylanicum Linn., 10331, cultivated in gardens. 
DIOSCOREACEAE. 
There are 3 collections of Dioscorea, 6971 in fruit, 9068 and 10403 with 
staminate flowers; vegetatively all three might be the same, but the inflorescence 
of the staminate numbers is quite different, 9068 having fascicled axillary spikes, 
while in 10403 the fascicles are numerous, separated by about 2 cm on an axillary 
peduncle. Both belong to the group with entire leaves and 6 fertile anthers. 
The fruiting specimen, belonging to the section Eudioscorea, is probably the same 
species as 9068. 
IRIDACEAE. 
Belamcanda chinensis (Linn.) DC. grows in waste places in the town of 
Polillo; it has doubtedl ess been introduced but is as well established as almost 
any weed in the place; 9050. 
MUSACEAE. 
No collections were made. Musa par.adisiaca Linn, and M. textilis Nee are 
both cultivated.
