ASCLEPIADACEAE. 
Cynanchum schlechterianum Warb, in Perk. Fragm. FI. Philip. (1904) 121. 
Fruiting material, 9231, probably represents this species, otherwise known 
from Tayabas, the only apparent difference being shorter petioles. 
Dischidia hirsuta (Blume) Decne. in DC. Prodr. 8 (1844) 632. 
The Polillo collection, 101/08, agrees fairly well with material from Masbate, 
identified by Schlechter, but is less hirsute. The identifications in this genus 
are somewhat approximate only, as the rather scanty material is reserved for 
dissection, by a specialist on the family. 
Dischidia oiantha Sehltr. in Perk. Fragm. FI. Philip. (1904) 127. 
Probably represented by 921/0 ; type locality Cagayan, apparently a species of 
fairly wide Philippine distribution. 
Dischidia platyphylla Sehltr. in Philip. Journ. Sci. 1 (1906) Suppl. 300. 
Probably represented by 10337 ; type from Mindanao. 
Dischidia sp. 
A species with great general resemblance to the last but with different flowers 
is represented by 921/1/, well matched by Merrill 5219, from Borongan, Samar. 
It is possibly the same as a named but undescribed species from Mindanao, our 
specimen of which has no flowers. 
Hoya incrassata Warb. in Perk. Fragm. FI. Philip. (1904) J30. 
Represented by 10336 ; other distribution Rizal, Tayabas, Mindoro, Mindanao. 
Hoya merrillii Sehltr. in Perk. Fragm. FI. Philip. (1904) 131. 
Represented by 9013, 101/31 ; other distribution Tayabas, Bohol, Mindoro, 
Mindanao. 
Other species: Asclepias curassavica Linn., 9051, 10378: Centrostemma multi- 
florum (Blume) Decne., 6975, 10362. 
CONVOLVULACEAE. 
This family was represented by very few species, the only two collected being 
Ipomoea pes-caprae (Linn.) DC., 6963, and Merremia hast at a Hallier f., 9153; 
one other was seen. 
BORAGINACEAE. 
Cordia subcordata Lam. 111. 1 (1794) 421. 
Represented by 10351; other distribution Tayabas, Camarines, Batangas, Bu- 
rias, Mindoro, Palawan, Mindanao, Basilan, East Africa, Madagascar, southern 
Asia, Malaya, to Australia and Hawaii. 
Other species: Tournefortia sarmentosa Blume, 9212. 
VERBENACEAE. 
Callicarpa subalbida Elmer Lead. Philip. Bot. 1 (1908) 337. 
Represented by 6861, 10269 ; otherwise known only from Tayabas. 
Clerodendron minahassae Teijsm. & Binnend. in Tijdschr. Ned. Ind. 25 
(1863) 409. i
