Plants Collected in Paraguay. 55 



MALYACEJE. 



This order is very prolific of species and individuals in Paraguay. 

 Indeed, some of the species run so closely together that it is not 

 easy to separate them. In a radius of 3 or 4 miles, on the Pilco- 

 mayo River, I found no less than 12 or 15 species of the small, 

 shrubby forms which insensibly graded into each other, and even 

 the genera were hard to distinguish,

Malvastrum tricuspidatum, A. Gray, PI. Wright, ii, 16. 



Asuncion (57 a) ; Pilcomayo River (995). November-April. 



A small shrub about 6 dm. high. The fruit is striking, being a 

 broad, flat pod of 10-12 peculiar carpels with grooves between them. 

 A row of short, stiff hairs stands on each carpellary edge, and at 

 the commencement of the curve of the point there are 2 minute pro- 

 jections, the point ending in 2 similar projections, each of which is 

 tipped with a weak spine. In the perfectly mature fruit, these rows 

 of hairs make the carpels quite rough. Each carpel contains a sin- 

 gle large, flat, smooth seed which perfectly fills it.
