(_With a Plate._) The plant, which is the subject of the following observations, is found growing abundantly on the sandy plains east of Cedar Hill, in New-Haven. It is locally associated with the asclepias viridiflora and verticillata. When this species of asclepias was first noticed by me, it was supposed to be a variety of viridiflora of Rafinesque and Pursh; but after examining a great number of specimens, it was found that the varieties did not blend themselves. The leaves of the viridiflora being uniformly oblong and obtuse, the leaves of the other uniformly lanceolate and acute. To this new species I purpose to give the name Lanceolata. _Specific character of the asclepias lanceolata_:--Stem decumbent, hirsute; leaves opposite, lanceolate, acute, sub sessile, hirsuit umbels lateral, solitary, sessile, nodding, subglobose, dense-flowered; appendage none.
