CHLORIS Swartz 



CHLORIS INCOMPLETA Roth Nov. Sp. PI. (1821) 60; Hook. f. Fl. Brit. 

 Ind. 7 (1897) 290. 



Mindanao, District of Zamboanga, Merrill 8279, December 6, 1911, 

 along roadsides near Calarian, and on dry hills back of Zamboanga, ascend- 

 ing to at least 200 meters altitude. Palawan, Taytay, Merrill 9275, sandy 

 seashore; Silanga, Merrill 9616, Phil. PL 1308 Merrill, open places near the 

 seashore. Luzon, Province of Zambales, Gates. 



Not previously reported from the Philippines, India, Formosa, and 

 Malaya. In addition to the Philippine specimens, cited above, I have 

 before me also Henry 1151 from Formosa, and Koorders 21237 from Java. 

 Chloris mearnsii Merr., from Luzon, is allied, but is much smaller, with 

 much narrower leaves, fewer, slenderer, and shorter spikes, and smaller 

 spikelets.

Coix heteroclita Roxb. Fl. Ind. ed. Carey 3 (1832) 572.

Mindanao, Bukidnon Subprovince, Tongkulan, C. F. Baker 3616, June,

The first representative of the genus to be found in the Philippines, here 

 recorded under its oldest specific name; India to Burma, Tonkin, and Java. 



CYPERACEAE 



CLADIUM Schrader 



CLADIUM RIPARIUM (Nees) Benth. Fl. Austral. 7 (1878) 405; C, 

 B. Clarke 111. Cyp. (1909) t. 85, fig. 5-8. 

 Chapelliera riparia Nees in Lehm. PI. Preiss. 2 (1846-48) 76. 

 Baumea riparia Boeckl. in Linnaea 38 (1874) 246. 



Mindanao, Lake Lanao, Camp Keithley, Mrs. Clemens 916, January, 

 1907, in swamps. 



In attempting to identify the above specimen, it was suspected that it 

 might represent the species described by Gaudichaud as Baumea glomerata, 

 and accordingly a duplicate was sent to the Museum of Natural History, 

 Paris, for comparison with Gaudichaud's type. Dr. E. G. Camus, who 

 kindly made the comparison, reports that it is not Gaudichaud's species, 

 but is manifestly the same as Cladium riparium Benth., in which identifica- 

 tion I concur after studying the description of Bentham's species and 

 fragments supplied me by Doctor Camus for comparison. A distinct 

 Australian type.
