2T2 Plants Collected in Paraguay. 



iiiayo. Culms 1-1^ m. in height. Distinguished by its numerous 

 finger-like, soft-haired spikes which are 10-15 cm. in length. Some- 

 times as many as 25 of these spring from the apex of the stem. 

 The fleecy hairs and the needle-like awns of the flowering glume 

 and palet impart a fuzzy appearance to the spikes. 



Tricllloris fascicillata, Fourn., Enum. Mex. PI. Grram. 142. 



Pilcomayo River (984). April. = C. Wright, Texas Y64. 



This grass occurs in Mexico and crosses the boundary into Texas. 

 It is quite common along the banks of the upper Pilcomayo. The 

 flowers are in densely crowded verticillate spikes at the top of the 

 culm. The plant appears in the Paraguayan form to have much 

 longer spikes (12-18 cm.) and a stouter and taller (1^-2|- m.) culm 

 than in any of the Mexican specimens that I have seen. The very 

 slender awns are sorhetirties 15 mm. long. 



Eleusine Indica (L.), Gsertn., Fruct et Sem., i, 8. 



Asuncion (61). November-January. 



£leusine Indica (L.), Gsertn., var. brachystachya, Trin., Sp., t. 72. 



Asuncion (68). 



Both of these forms grow in the streets of Asuncion, as well as 

 in grassy places in the suburbs. The variety has much shorter and 

 broader panicles, the spikelets closely crowded, and 1-3 spikes, while 

 the type has 3-5 narrowly linear spikes. Sometimes erect and 20-30 

 cm. high, but usually prostrate with ascending culms 6-15 cm. high.

This grass has a hard, smooth, reed-like culm l-lj m. high. 

 Panicle 15-30 cm. in length. Spikes drooping, slender, 5-12 cm. 

 long, 1-3 rising together from the rachis. Glumes and palets 

 often purple-tinged. Culm occasionally branching, thickened at the 

 branch nodes. Panicle sometimes on long naked peduncles, some- 

 times sheathed by a leaf. 



Tricuspis latifolia^ Griseb., PI. Lorentz., 211.
