Panicula 10-25 cm. longa, ex anthelis 2 vel 3 magis minusve distantibus 
omposita, multiflora, anthelæ infimee bractea late vaginante laminant brevem 
ensiformem gerente 1—3 cm. longa, cæteræ bracteis similibus sed brevioribus 
at sepe valde reductis suffultee ; anthelarum rami pauci vel numerosi, valde 
insequales, longiores ad 8 em. longi et ad 6 em. indivisi, superne magis minusve 
ramulosi; ramuli fasciculati et inzquales, uti rami pubescentes, longiores

subdistichæ, infima spiculam dimidiam æquans vel paulo brevior vacua (in 
spicula pedunculata terminali bracteæ par subtendenti homologa et eam 
sæpe forma pubeque magis minusve appropinquans), secunda tertiaque fertiles, 
tertia secundam paulo superans, quarta brevior ut quinta minuta vacua, 
secunda a latere visa oblique lanceolata, subacute vel acute acuminata, 5 mm.

tertia a latere visa suboblique oblonga, obtusiuscula vel minutissime mucro- 
nulata, 5*5 mm. longa, cæterum secundæ consimilis, quarta forma tertie sed

interdum solus fructum maturans. — Perianthemum nullum, Stamina 3 rarius

I am inclined to refer to this species a plant collected by Beccari on 
Mt. Singalan, Sumatra (n. 213) and Merrill’s Cladium latifolium, described 
in * Philippine Journal of Science,’ ii. (1907) 262, of which I have seen the 
following specimens: R. S. Williams, no. 2614, from Mt. Apo, Mindanao,
