ON THE FLOEA OF BOENEO. 77 



3 mm. longis, quam fertilibus distincte longioribus, obscure 5- 

 nerviis, apicem versus ciliato-setosis, marginibus inflexis ; glumis 

 fertilibus oblongo-ellipsoideis, rottmdatis,- 2 mm. longis, leviter 

 apprese pilosis. 



A rather rigid ascending, scarcely tufted plant, the culms 

 glabrous, attaining a length of about 20 cm., below prostrate 

 and rooting at the nodes. Leaves rigid, lanceolate, acuminate, 

 1.5 to 3.5 cm. long, 4 to 8 mm. wide, base rounded, somewhat 

 clasping the stem, the lower surface with few, long, white, 

 spreading hairs or glabrous, the margins rather prominently 

 denticulate, the minute sharp teeth distinctly visible to the 

 naked eye, below often ciliate-pilose with long white hairs; 

 sheathes overlapping, ciliate-pilose with long, spreading, white 

 hairs ; ligule none. Panicles terminal, exserted, few-flowered, 

 glabrous, 3 to 4 cm. long, the branches few, solitary, spreading, 

 at most 1 cm. long, each bearing 2 or 3 spikelets, the pedicels 

 of the lateral spikelets about 1.5 mm. long, of the terminal one 

 longer. Empty glumes equal, oblong, obtuse, 3 mm. long, 

 margins inflexed, somewhat spreading, obscurely 5-nerved, 

 toward the apex sparingly ciliate-setose, distinctly exceeding 

 the flowering glumes. Flowering glumes two, oblong-ellipsoid, 

 rounded, 2 mm. long, sparingly appressed-pilose.

In many characters approaching Isachne pangerangensis, 

 Z. & M., but not densely tufted, much taller, with larger leaves, 

 and quite different spikelets. In its empty glumes distinctly 

 exceeding the flowering glumes it approaches Isachne Icun- 

 thiana, W. & A., but is not otherwise closely allied to that 

 species. 



Isachne kinabaluensis, sp. nov. 



Laxe caespitosa, erecta, rigida, usque ad 45 cm. alta, culmis 

 simplicibus, nodis barbatis, vaginis margine ciliatis, cetero 

 glabra vel subglabra; foliis lanceolatis, rigidis, subcoriaceis, 

 acuminatis, usque ad 8 cm. longis, margine cartilagineis, in- 

 tegris vel minutissime ciliato-denticulatis ; paniculis longe 

 exsertis, usque ad 9 cm. longis, paucifloris, ramis patulis, in- 

 ferioribus usque ad 5 cm. longis; spiculis 2 mm. longis, longe 

 tenuiterque peclicellatis ; glumis vacuis orhiculari-ellipticis, 

 rotundatis, glabris vel apice obscurissime ciliatis, 7- vel 9- 

 nerviis; glumis fertilibus ellipticis, 1.7 ad 2 mm. longis, basi 

 et apice et margine parcissime ciliatis. 



A laxly tufted, erect, simple, rigid, nearly glabrous grass 

 attaining a height of about 45 cm., the culms smooth, glabrous, 

 the nodes bearded. Leaves rigid, subcoriaceous, acuminate, 

 base somewhat rounded, 3 to 8 cm. long, 5 to 9 mm. wide,
