Paspalum notatum var. satjrae 

 Parodi. A more hardy form, 40 to 70 

 cm. tall, with blades to 35 cm. long, 

 the racemes 2 or 3, rarely to 5, sub- 

 erect, the spikelets 2.8 to 3 mm. long, 

 is showing promise of becoming an 

 important forage and erosion-control 

 grass in the Southern States. This has 

 been found in lawns at Wilmington, 

 N. C, Pensacola, Fla., and in several 

 localities in Texas. It has been called 

 the "Pensacola strain." An introduc- 

 tion from Paraguay belongs to this 

 form and has come to be known as the 

 "Paraguay strain." It has been con- 

 fused with Paspalum minus Fourn., a 

 distinct species that occurs in a few 

 localities in Texas. Ql — Paraguay 

 and Argentina.

10. Paspalum minus Fourn. (Fig. 

 871.) Resembling P. notatum, com- 

 monly in denser mats; culms rarely 

 more than 30 cm. tall; racemes more 

 slender; spikelets 2 to 2.5 mm. long, 

 less shining than those of P. notatum. 

 % — Open slopes and savannas, 

 eastern Texas; Mexico to West Indies 

 and Paraguay. 



11. Paspalum almum Chase. 

 Combs paspalum. (Fig. 872.) Culms 

 in very dense tufts; blades flat, 2 to

3 mm. wide, long-hirsute on the upper 

 surface at base, papillose-hirsute on 

 the lower surface toward the ends, 

 the margins stiffly ciliate toward 

 base; racemes slender, approximate, 

 scarcely paired, occasionally 3, as- 

 cending, 5 to 9 cm. long; rachis 1 

 mm. wide, minutely wing-margined; 

 spikelets 3 mm. long, 1.8 to 2 mm. 

 wide, obovate-elliptic; sterile lemma 

 slightly concave. % — Sandy or 

 silty clay loam, Jefferson County, 

 Tex.; Brazil, Paraguay, and Argen- 

 tina. An excellent forage grass. 

 5. Setacea. — Culms compressed from 

 a knotted base or very short rhi- 

 zome; blades mostly flat; inflo- 

 rescence terminal and axillary, the 

 axillary sometimes hidden in the 

 sheaths; racemes 1 to few, slen- 

 der, subcylindric; spikelets in 

 pairs, crowded. Species closely 

 related with frequent intergrades. 

 12. Paspalum longepedunculatum 

 LeConte. (Fig. 873.) Culms slender, 

 ascending or suberect, 25 to 80 cm. 

 tall; leaves mostly aggregate at the
