In view of the facts that the Compositae is a family represented 
in the Philippines and in the Malayan region generally by com- 
paratively few genera and species; that few of the genera are 
confined to this particular region; and that a high percentage 
of the species are manifestly introduced ones here, it is rather 
surprising that our recent collections should present two appar- 
ently undescribed generic types from the Philippines. There are 
recorded to-day from the Philippines about one hundred forty 
species of Compositae, of which but about 35 per cent are en- 
demic. In this family it is now comparatively rare that either 
new species or those previously described from extra-Philippine 
material are discovered in the Archipelago. 
In the present paper I present descriptions and figures of two 
new genera, while for convenience I add the descriptions of two 
other new species in the well-known genus Gynura and record 
two representatives of other genera as new to the Philippine | 
flora. The drawings accompanying the present paper were made 
by Mr. J. K. Santos, assistant in the botanical department, Col- 
lege of Liberal Arts, University of the Philippines.
