Calyx 5-clcft, the lobes nearly equal, slender. Stamens diadolphous (9 & 1) :

 Perennials with pinnately 3-foliolatC leaves, not stipellate. Stipules and bracts 

 minute. Flowers often polygamous (Dedicated to Lespedez, the Spanish

«= Flowers of two sorts, the larger {violet-purple) perfect, but seldom fruitful, panicled 

 or clustered; with smaller pistil/ate and fertile but mostly apclalous ones intermixed, 

 or in subsessile little clusters. 



1. Li. pi'OCUmbcaiS, Michx. Sof -downy, except the upper surface of 

 the leaves, trailing, slender; leaflets oval or elliptical ; peduncles slender, mostly

 flowers; this runs into, 2. sessiliflora, with the flowers principally on pe-
