 Northern Luzon to Mindanao, in most islands and provinces. In shallow- 

 fresh water of lakes, pools, and slow streams. India through Malaya to 

 tropical Australia. 



A species presenting great variation in its vegetative characters, which 

 largely depends on the depth of the water In which it grows, whether 

 stagnant or not, and whether the plants are crowded or scattered. Two 

 additional synonyms are Ottelia javanica Miq. and O. ovalifolia L. C. Rich., 

 credited to the Philippines by Naves, Novis. App. (1880) 214, as distinct 

 species.

TRIURIDACEAE 



1. SCIAPHILA Blume 



SC1APHILA CLEMENSAE Hemsl. in Hook. Ic. IV 9 (1907) t. 2850, f. 7-W, 

 Fedde Repert. 5 (1908) 265. 



Mindanao (Lanao), Clemens 775. In damp primary forests at low alti- 

 tudes. Borneo. 



This species seems to be closely allied to S. tenella Blume. Dr. J. J. 

 Smith states that B. S. 63U7 Robinson, F. B. 9350, 9U9 Whitford & Hut- 

 chinson, and Clemens 775 p. p. are very similar to Blume's species. 



SCIAPHILA M AC U LATA Miers in Trans. Linn. Soc. Bot. 21 (1852) 48, 

 t. 6, f. 19-36; Vidal Phan. Cuming. Philip. (1885) 154, Rev. PL 

 Vase. Filip. (1886) 282. 



Luzon (Bataan), Mindanao (Butuan, Zamboanga), F. B. 5537 Curran, 

 9126 Whitford & Hutchinson, Weber 11*62. In damp primary forests at 

 low and medium altitudes. Endemic. 



In addition to these two species what may be Sciaphila tenella Blume 

 occurs in our collections, as noted above, as well as fragmentary material 

 representing two other distinct species.
