diameter, the lower branches often 1 cm lung, closely apprest^ed, the 

 rachis and branches glabrous, the pedicels 0.3 to l..") una long. Spikelets 

 numerous, ovate to oblong-ovate, 3 mm long, usually dark-purple, some- 

 times greenish. Kmpty glumes subequal, 7-nerved, glabrous except for 

 few long hairs on the apical parts. Third glume elliptic-oblong, 1.8 

 mm long, with very few, obscure, short hairs, the margins obscurely 

 ciliate, the palea as long as the glume, inclosing a d" flower. Fourth 

 glume similar to the third, slightly shorter, containing a $ flower. 



Xegkos, Canlaon Volcano, Merrill 6975, April, 1910. 



Abundant in tlie old crater, on bare slopes and on debris wasiied down from 

 the new cone, forming dense tufts or mats, altitude 1,800 to 2,100 m. A species 

 well ciiaracterized by its dense panicles, short, rigid, densely caespitose habit, 

 rigid. crowdcMJ leaves, and dark-purple spikelets. 



MISCANTHUS Anderss. 



Miscanthus depauperatus sp. nov. 



I'ulmis erect is vel suberectis, usque ad GO cm altis, deusissime caes- 

 pitosis, vi.x 3 mm diametro; foliis 3 ad 6 mm latis, margine scabridis; 

 spiculis purpureis, 6 mm longis; paniculis laxis, racemis paucis, race- 

 moso-dispositis, solitariis vel inferioribus binis, usque ad 15 cm longis. 



A densely caespitose perennial, forming tufts up to 1 m in diameter, 

 the culms erect or ascending, usually about 40 em high, often sliorter, 

 rarely GO cm in lieight, simple or very rarely branched, terete, 2 to 2.5 

 mm in diameter. Ficaves nunu'rous, those of the culm up to 30 cm long, 

 G mm wide, the basal ones inueli shorter and usually luirrower, scabrid 

 on the nuirgins, long- and slenderly acuininate; sheatlis exceeding the 

 internodes, the lower ones usually purplish ; ligules broad, about 2 mm 

 long, margins ciliate. Panicles exserted or not, glabrous, the rachis and 

 branches angled, purple, minutely scabrid on the angles, the rachis always 

 less than 5 cm in lengtli, the branches rather slender, erect or somewhat 

 spreading, solitary, or the lower ones in ])airs, 3 or 4 to about '.» in 

 number, 4- to 15 cm in lengtli. Spikelets purple, lanceolate, acuminate, 

 about G mm long, the; shorter pedicels about 2 mm long, the longer ones 

 5 to G iMiii Ioiil;-. the iiiNolucral hairs slendei", about as long as the spike- 

 lets, usually inirplish, unequal in length, numerous. First two glumes 

 lanceolate, sharply acuminate, equal, about G mm long, when spread 2.3 

 unn wide, [)urple, shining, glabrous, or the margins with very few ciliate 

 hairs, the first obscurely 5-nerved. the second obscurely 3-nerved. Third 

 glume oblong-lanceolate, hyaline, 5 mm long, 2 mm wide, acuminate, 

 1-nerved, margins slightly ciliate, empty. Fourth glume liyaliiu'. lanceo- 

 late, acuminate, 4 mm long, 1 mm wide, apex cleft into two slender 

 te(!tli and bearing between them a slender, scabrid, twisted awn about 1 

 cm in length. I'alea ovale, hyaline, 1 luin long. Lodicules truncate, 

 al)out 0..S tnin long. Anthers 3. 2.5 to 3 iniu buig.
