STNGEKiESIA. SUPERFLUA. 161 



To add to the error of Michaux, Mr. Pursh says that tlie 

 leaves are very entire. In any other species, less sinj^ular, 

 the identity would have been impossible. S. humilis ap- 

 pears to be a variety of this species. 



33. * pulvendenta. Stem tall, perfectly simple, and ia 

 common with the leaves and peduncles pulverulently pu- 

 bescent; leaves sessile, impunctate, lower ones elliptic, 

 serrate, the upper much smaller, obovatc and entire, mar- 

 gin scabrous; raceme erect, solitary, compound, spiciform; 

 scales of the calix thickish, partly acute; rays elongated, 

 about 10. Hab. In Georgia and Florida. — Dr. Baidwyn. 

 — A species which might almost be confounded with tlie 

 preceding, though quite distinct. Stem 3 or 4 feet high, 

 attenuated, sometimes reddish. The lower leaves are 

 acute, and somewhat resemble those of Spiraa saUcffoua. 



34. erecta? Herb. Banks, mss. Stem simple, 1 or 2 

 feet high, partly villous in common with the peduncles 

 and under side of the leaves; leaves all nearly equal, en- 

 tire, elliptic-lanceolate, subpetiolate, acute, and strongly 

 veined; racemes erect, axillar and terminal, 3 or 4 indies 

 long, peduncles filiform, pubescent, naked; scales of the 

 calix acute. Haf. In open swamps near Wilm.ington, 

 North Carolina. It may possibly be distinct from S. erec- 

 ta, as nothing certain can be tierived from such vague 

 descriptions. This species is remaikably low, and singu- 

 lar for the equality of the leaves, which arc 2 or 3 inches 

 long, scarcely an inch wide, and subpetiolate. 



35. livida. 36. hirta- 37. Uthospermifolia. 38. hispida. 

 39. cicsia. Stem glaucous. 40. jftexiccmlis. 41. macro- 

 phijlla. Scarcely distinct from the following. 42. glome- 

 rata. Lower leaves broad oval, and acuminate, serrate. 

 Nearly allied to Asier. 



43. * squarroi-a. Robust; stem thick and pubescent 

 above; leaves smooth, lower ones very broad, spathulate- 

 oval, serrate, acute, marg-in scabrous, the upper sessile, 

 lanceolate-elliptic, entire; racemes glomerate, rigid and 

 pubescent; calix squarrose! man\ -flowered, rays elongat- 

 ed, 10 or 12. Hab, On the rocky banks of the Ilariton, 

 near New Brunswick, (New Jer:.ey,) &c. According to 

 Muhlenberg's Catalogue, it exists also in Pennsylvania 

 and Georgia. Allied to S. strlcta. — Stem thick, 2 to 3 

 feet high, always simple; lower leaves dilated, upper 

 much smaller, very acute, subacuminate, someti.mes 

 slighUy scabrous on the upper side alung the mid-rib. 

 I'lowers nearly as large as those of S. risnda: racemes 

 axillary, thick and crowded, forming a compound spike. 

 Seeds smooth. This is one of the finest species, and dis- 

 tinguished from all others by its squvirrose calix.
