March 27, 1915] Two Hunprep Twenty Six New SpPrecies—I 2681 
usually strigose from its base, truncate. Spikes terete, 1.5 
mm thick, ascending and curved, terete, green except the 
reddish brown glumes, dark brown when dry, varying from 
3 to 8 em in length; inflorescence slenderly elongated, 3 
to 3.5 dm long, alternatingly branched from the base but 
bearing more spikes toward the top, the younger spikes well 
enclosed by the uppermost leaf sheath; the branches much 
ascending, 3 to 5 or even 8 cm long, very slender, oc- 
casionally provided with a sharply pointed bract-like leaf; 
the outer or protecting glumes at least 3 mm long and 1 
mm wide, straw brown, thick and very rigid, glabrous, 
distinctly truncate at the base, apex obtusely rounded, only 
slightly scabrid on the back, not ridged or punctate, in 
anthesis separating at the apex from the rachis, not exceed- 
ing the internodes, the edges well curved over the ventral 
side; the glume next to the rachis subhyaline or the mar- 
gins somewhat thickened, 2 mm long or nearly so, deeply 
folded on the ventral side, ovately elongated, subacute at 
the apex, about 1.5 mm wide below the middle, the other 
inner glumes or palea increasingly smaller and all hyaline; 
flowers apparently 2; fertile stamens 8, their filaments very 
fine and hyaline; anthers somewhat curved and a trifle wider 
toward the base, otherwise linear, 2 mm Jong, dark brown, 
subterete, well bifid at the base and less so at the apex, 
0.5 mm wide; ovary obelongated, styles filamentous, stigmas 
long and feathery. 
Type specimen number 10984, A. D. E. Elmer, Todaya 
(Mt. Apo), District of Davao, Mindanao, June, 1909. 
Discovered in a hardpan ground among the cogon grass 
at 1500 feet altitude or along the upper limit of the true 
cogonal. The Bagobos call it “Girun.” Named after Datu 
Tongaling, the Bagobo chief who has taken quite an interest 
in the collecting work and who has given me material 
assistance in my exploration. 
Apparently nearest to Rottboellia ophiuroides Benth. Num- 
ber 2617 of Mr. Williams from the same general region is 
the same species. Number 11817 of my own distribution 
from Dumaguete (Cuernos Mts.), Negros is also identical 
although it was years ago sent out under Rottboellia ophiuroides 
Benth.
