 y. Tampa Bay, Florida, Dr. Burrows!— 'Stem scarcely more than a span

Sandy soils, Georgia, Lijon (ex Pursh) ; South Carolina, Elliott. July- 

 Aug. — I1 1 Stem 12-lR inches high, branching, stellately tomentose rather 

 than hispid. Leaves somewhat rhomboidal, a little hairy on both surfaces: 

 petioles 1-2 lines long. Stipules subulate, hairy, longer than the peduncles 

 or petioles. Flowers on small axillary branches, so crowded and so nearly 

 sessile that they appear fascicled. Calyx angular, hairy. Petals yelloAv, a 

 little longer than the calyx. Fruit not seen. — There is no exterior calyx, 

 but the stipules are very often found adhering to the calyx, as if connected 

 with it. Elliott. — We have not seen this species.
