1 6e. F. OVINA MAGELLANICA (Lam.) Hack. (F. magellanica Lam.) 



Rhizome branching, its branches long-filiform, producing fertile and 

 sterile culms to 20 cm. high. Leaves shorter than culm, convolute-fili- 

 form, pubescent inside, smooth outside ; ligules short, ciliolate. Panicle 

 simple, slightly unilateral, rigid, 5-7 cm. long; its spikelets 7-10 mm., 

 oval, 4-5-flowered. Glumes unequal, acute, the lower i -nerved, linear, 

 the upper 3-nerved, lanceolate, half as long as the spikelet. Flowers 

 spreading, not purplish but olive, shortly awned. Ovary glabrous. Vary- 

 ing much, foliage always rigid.

 plane, rarely half as high as the culm ; ligules long. Panicle contracted, 

 linear ; pedicels scabrid. Spikelets 7 mm. long, 4-flowered ; glumes sub-

Culm stout, erect, 45-60 cm., glabrous. Leaves thickish, lanceolate, 

 rigid-acuminate, 7-17 cm. by 8 mm. at base; ligules short, laciniate ; the 

 lowest sheaths often ending in short lanceolate appendages. Panicle

 purplish ; floral glume with minute setulae.

 much shorter, smooth, convolute. Panicle lax, cernuous, its rays rather 

 short, suberect. Glumes lanceolate, mucronate, purplish, the lower 

 scarcely more 3-nerved than the upper. Flowers 2-3, scarcely exsert,
