78 ON THE FLOEA OF BORNEO. 



glabrous, or the margins very minutely ciliate-denticulate, 

 often, however, entire, cartilaginous; sheaths generally over- 

 lapping, glabrous except the prominently ciliate margins; 

 ligule none. Panicles lax, pyramidal, long-exserted, up to 9 

 cm. in length, few-flowered, the branches solitary, spreading, 

 the lower ones up to 5 cm. in length, quite smooth and glabrous, 

 the pedicels slender, 6 to 15 mm. in length. Spikelets 2 mm. 

 long; empty glumes equal, orbicular-elliptic, rounded, 7- or 

 9-nerved, glabrous or the apex very obscurely and sparingly 

 ciliate; flowering glumes elliptic, 1.7 to 2 mm. long, rounded, 

 the base, apex, and margins sparingly ciliate, otherwise glabrous. 



British Korth Borneo, Mount Kinabalu, Paka Cave to 

 Lobang, between the altitudes of 1450 and 3000 meters, 

 Clemens 10704, (type) Xovember 15, 1916; near Kiau, alti- 

 tude about 930 meters, Clemens 10029, mixed with Panicum 

 cordatum, Biise. 



Probably as closely allied to Isachne beneckii, Hack., as 

 any other species, differing, however, in numerous characters.

This species has previously been reported only from Java ; 

 the Bornean specimen agrees closely with the original descrip- 

 tion, and agrees with Javan specimens kindly supplied by Mr. 

 Backer of Buitenzorg. As noted by Mr. Backer Agrostis in- 

 firma, Biise, is not clearly distinguishable from the widely dis- 

 tributed Agrostis alba, Linn. 



Agrostis -canina, Linn., var. borneensis, Stapf, is represented 

 by Clemens 10630, from the same locality as A. infirma, Biise, 

 while a third species, much more delicate than either of the 

 above, is represented by Clemens 10632, from the same general 

 altitude, a single specimen.
