 1004; (100 DeVore d Hoover) April, 1903.

Perhaps only a variety of Setaria glauca, distinguished from the typical state 

 of that species, especially in the decidedly smaller Bpikelets.

LUZON, .Manila {Merrill) July, L905. A single specimen found along a city 



street, introduced. 



(4) Setaria laxa Merrill, sp. nov. 



Culmis debilibus, erectis, glabris, ramosis, at 1 m. altis; vaginis quam 

 internodiis multo brevioribus, glabris vel sparse pilosis, margine sursum 

 ciliato-pilosis ; laminis linearilms vcl anunsto-lanceolatis, membranaceis, 

 7—16 cm. longis; paniculis I axis, elongato-pyramidatis, ad 20 cm. longis, 

 paucifloris, rami's ramulisque interdum pedicellis in setam productis, seta 

 scabra, 8—4 nun. longa; spiculis paucis, solitariis vcl binis, glabris, 3—2.2 

 mm. longis. 



A slender, erect branched, Qearly glabrous grass about 1 m. high, the 

 culms 1.5 to 2 nun. thick, glabrous; nodes glabrous. Sheaths much 

 shorter than the internodes, glabrous or Blightly pilose, the margins 

 above ciliate-pilose : ligule ciliate; blades linear or narrowly lanceolate, 

 membranaceous, acuminate, 1 to l<i cm. long, 3 to 5 nun. wide, glabrous 

 or beneath along the nerves with few long white hairs, the margins and 

 nerves scabrous. Panicles lax, elongate or elongate-pyramidal, erect, 

 aboul 20 cm. long, the branches slender, erect-spreading, aboul 8 cm. 

 long, few-flowered, scabrous, the branches, branchlets, and sometimes the 

 pedicels produced into a '3 to 1 mm. long scabrous awn. Spikelets few, 

 purplish, solitary or in pairs, glabrous, narrowly ovate, acute, 2 to 2.2 

 mm. long, the first glume 3-nerved, ovate, acute. 0.6 mm. 1 on g ; "second 

 glume 5-nerved, ovate, acute, l.l mm. long; third glume 5-nerved, '* mm. 

 long; flowering glume 2 mm. long, narrowly ovate, acute, minutely 

 rugose. 



Lr/.ox, Province of l.ayima. Los Pafios {llnllier) December, 1003. 



A species characterized by its lax habit and panicle, narrow leaves, and com- 

 paratively few spikelets. The panicle branches are slender and branched from 

 the base, usually solitary, alternate. Perhaps as near Panicum S Ptycophyllwn 

 as Setaria, but the narrow leaves are not at all plicate and the pedicels usually, 

 hut not always, end in a single bristle subtending the spikelet. No. 21157 \i 

 Koordera from Java is very nearly the same, but in that specimen the leases are 

 tuberculate hispid or pilose.
