UMBELLIFERAE 

 1. HYDROCOTYLE Tournefort 



HYDROCOTYLE BENGUETENSIS Elm. Leafl. Philip. Bot. 2 (1909) 628. 



Luzon (Lepanto, Bontoc, Benguet), Mindanao (Lanao), Elmer 8903, 

 6496, Merrill 7657, 4516, Phil. PI. 764, Clemens 919. In cool open swampy 

 places, altitude 650 to 2,200 m. Formosa! 



Perhaps only a form or variety of H. sibthorpoides Lam. with deeply 

 lobed leaves. 



HYDROCOTYLE DELICATA Elm. Leafl. Philip. Bot. 2 (1909) 629. 



Luzon (Bontoc, Benguet, Laguna), Negros, Mindanao (Davao), Elmer 

 8895, Merrill 4352, 6989, Vanoverbergh 1093, Clemens 9101, B. S. 9782 

 McGregor. In open wet places, on damp rocks, etc., altitude 800 to 2,300 

 m. Endemic. 



This seems to be matched by Riu Kiu material referred to H. rotundifolia 

 Roxb. It may be referable to H. sibthorpoides Lam. 



Local name: Sigbut-ta-bato (Bag.). 



HYDROCOTYLE JAVANICA Thunb. Diss. Hydrocot. (1798) No. 17, t. 2; 

 Hook. f. Fl. Brit. Ind. 2 (1879) 667; F.-Vill. Novis. App. (1880) 

 100; Vidal Phan. Cuming. Philip. (1885) 116, Rev. PI. Vase. Filip. 

 (1886) 144; Elm. Leafl. Philip. Bot. 2 (1909) 629. 



Luzon (Benguet, Sorsogon), Mindanao (Lanao), Merrill 4420, Phil. PI. 

 752, Clemens 577, 669, B. S. 23452 Ramos. In ravines along streams, on 

 wet cliffs, etc., altitude 650 to 1,600 m. India to southern China and 

 Malaya. 



The identity of the Philippine material with Thunberg's species is un- 

 certain. The specimens are much smaller than Indian and Chinese ones 

 so named.
