It was on specimens Nos. 10, 84 and 338 Cuming that BaJccr based his 
imperfect description, and of these I have before me a specimen of the second 
mntiher. Based on this number, and the abundant material collected by the 
American botanists in the Philippines, the following detailed description is given:
