92 Plants Collected in Paraguay. 



Cassia oMongifolia, Vog., Syn. Cass., 23. 



Asuncion (350); Pilcomaj^o River (1097). December-January. 



This merits the specific name bestowed upon it by Yogel, for the 

 leaflets of 4 pairs are decidedly oblong, being 3j cm. long by Ij cm. 

 broad. It is a much branched shrub, 1^-2 m. in height, with a 

 terete stem, downy on the young branches. Flowers large, con- 

 spicuous, in terminal, leafy racemes, the corolla often 4 cm. in 

 diameter when expanded, and spread wide open rotately. Glands 

 large, thick, one between each of the 2 lowest pairs of leaflets, or 

 one only. Fruit a cylindrical pod 6-10 cm. long and some 6 or 7 

 mm. in breadth. Common in thickets. 



Cassia occidentalis, L., Sp. PL, 377. 



Asuncion (41). November-December. 



A shrub 12-15 dm. in height, common both in the streets of 

 Asuncion and in fields on the outskirts of the town. Stem smooth, 

 terete or angled above. The whole plant rather ill-smelling. Leaf-

Cassia pilifera, Vog., Syn. Cass., 23. 



Near Jaquaron (665). April. 



A Cassia with the lowest stems and the largest flowers of any 

 that I have seen in Paraguay. Stems not over 3 dm. in height, 

 shrubby, with long, scattered white hairs, angled, often prone or 

 bending over towards the ground. Leaflets in 2 pairs, large, oval, 

 mucronate, ciliate on the margins and hairy on the veins beneath. 

 Flowers very showy, bright yellow, often 6 cm. in diameter when 

 expanded, frequently lying upon the ground from the bending of 

 the stems. Fruit a narrow, linear, downy pod, 25 or more cm. in 

 length. A large patch of this was found in the clearing around a 

 native's house on the road betw^een Pirayu and Jaquaron, some 30
