5. M N N I N A, Ruiz & Pav. 



1. MONNINA MACROSTACHYA, Ruiz & Pav. 



Var. pumila; racemis breviusculis ; foliis caulinis inferioribus et radi- 

 calibus obovatis; fructu puberulo. 



Hab. Peru : common below Obrajillo. 



The same form was gathered near Lima and at Purruchuca by 

 Matthews. It appears to differ from M. herbacea, DC. only in having 

 a manifest wing to the fruit. Our specimens are small, 3 to 7 inches 

 high, from an annual root; the radical and some of the lower cauline 

 leaves broadly obovate; and the racemes are only an inch or two in length. 

 The wing of the fruit is glabrous or nearly so, but its disk is tornentose- 

 puberulent. 



2. MONNINA ANGUSTJFOLIA, DC. 

 Monnina angusti/olia, DC. Prodr. 5, p. 840; Presl, Rel. Hsenk. 2, p. 103. 



Hab. Peru; on a mountain ridge, between Lima and Yanga. 



Plant 2 or 3 feet high, with diffusely spreading and slender 

 branches. Fruit 2 or 3 lines in diameter, including the broad and 

 membranous wing, either glabrous or minutely tomentose, deeply 

 emarginate at both ends. — Perhaps not distinct from M. pterocarpa. 



3. Monnina linearifolia, Ruiz & Pav.
