Cochin-China and the Andaman Islands. 
I identified two of the above plants with a species from the Aru Islands ( as 
yet unpublished) ; but Merrill 1. c. says the Philippine plants cited above are 
all one species, and I consider that he is correct. 
3. Hypolytrum viridinux C. B. Clarke, ms. (1895) hb. Kew. 
Spicis parvis ; stylo 2-fido ; mice parva, matura viridi, reticulato- 
rngosa, rostro vix ullo albescente. 
Luzon, Montalban, (775 Loher)-, Benguet, (6223 Elmer). 
Borneo. 
This species is allied to H. latifolium L. C. Rich., but has much smaller spikes 
and nuts. In the type (from Sandakan) the nuts are remarkably green. 
4. Hypolytrum Philippense C. B. Clarke, ms. (1887) hb. Kew. 
Panicula composita, spiculis parvnlis, numerosis, brnnneis ; ceteroquin 
nt H. latifolium L. C. Rich. 
Luzon, Isabela, (3987 Vidal) ; Union, (779 Loher) ; Laguna, (5126 Merrill) ; 
Rizal, (77 Foxworthy) . Palawan, (744 Merrill). 
Endemic. 
This differs from E. viridinux in the very copious panicle; in the type (No. 
3987 Vidal) there are about 600 spikes. I have not seen the fruit. 
21. MAPANIA Aubl. 
1. Mapania humilis F.-Vill. Nov. App. (1883) 309. 
Leaves as though petioled, 30 to 45 mm. broad, flagellate at the tip.
