about 4 mm. long, oblong, 1 -nerved, cleft at the apex, awned from the 

 hack at the lower J. the awn straight, scabrous, about 6 mm. long; third 

 flowering glume broadly-ovate, obtuse, hyaline, glabrous, nerveless or 

 nearly so, hermaphrodite, inclosing a very narrow palea. Anthers nar- 

 rowly oblong, about 2 mm. long.

In the same locality and with the same associates as Poa luzoniensis, and 

 like that species a very interesting northern type. Hackel, who lias kindly 

 examined specimens, states that this species is apparently related to the British 

 Indian plant described by Hooker as Hicrocliloa clarkei, judging from the descrip- 

 tion. The present species differs from the well-known and widely distributed 



,t nthomani hum odoratum Linn., in its glabrous outer glumes and especially in 

 the very short awned first-flowering glume. It has the same characteristic odor 

 and much the appearance of that species.

This species is enumerated here only to call attention to the reduction of 

 Danthonia luzoniensis Steud. On receipt of a specimen of No. 1415 Cuming, 

 from the British Museum, I found the number to be an Arundinella and not a 

 DanthoniO: A fragment was sent to Dr. Hackel, who pronounced it to be identical 

 with Arundinella setosa Trim The genus Danthonia can therefore be excluded 

 from the Philippines. 



CALAMAGROSTIS Adans. 



Calamagrostis filifolia Merrill sp. nov. S Deyeuwia. 



A densely tufted, erect grass 150 to 60 em. high, with filiform leaves, 

 and strict, densely flowered panicles. Culms glabrous, many in each 

 tuft, erect, straight, glabrous; nodes dark, glabrous; sheaths, at least the 

 lower ones, shorter than the internodes, the upper one often inclosing the 

 immature panicles; ligule about '1 mm. long, subhyaline, irregularly cleft 

 or lacerate; blades 10 to 20 cm. long, numerous at the base of the culms 

 and on the innovations, erect, somewhat stiff, revolute, 1 mm. wide or less. 

 Panicles at length e.xserted. pale green or slightly purplish, many 

 flowered, the lower branches appressed, often 4 cm. long, forming a 

 narrow somewhat spikelike, uninterrupted panicle. Empty glumes sub- 

 equal, lanceolate, acuminate, about (i mm. long, both 1-nerved, scabrous 

 on the keel. Flowering glume lanceolate, 5 mm. long, minutely scabrous, 

 l-nervcd. the nerves green, entire or very obscurely 'I to .*i toothed at 

 the apex. Palea equaling the glume. Anthers 1.2 to 1.5 mm. long. 

 Lodictiles 1 mm. long. Callus hairs 1 mm. long or less; rhachilbi about
