y. flexicaulis (S. flexicaulis. P.) ; stem flexuous, angular ; leaves ovate- 

 lanceolate ; racemes axillary. Leaves hardly 2 inches long, and half an inch

 obtuse. In woods and dry hills. A species remarkably distinguished among 

 the solidagos by having white rays. Stem generally simple, 2 feet high, a 

 little hairy. Leaves hairy on both sides, mostly entire, gradually reduced in 

 size upwards. Flowers in numerous close, short, axillary clusters, forming a 

 long terminal, interrupted spike. Rays about 8, very short, yellowish-white,
