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

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.
