and the 2? followintr producing a single chaffy scale from 

 the centre. 2. reniformis. Common on the banks of th« 

 Susquehannah and Potomac rivers. 



3. * taberosa. Hoot tuberous, stem herbaceous; leaves 

 petiolate, ovate, obtuse, 5-nerved, entire; flowers corym- 

 bose, sabfastigiate; calix 5-flowered, naked, 5-leaved, leaf- 

 lets carinate. Hab. On shady hills near Natchez, on the 

 banks of the Missisippi, and also around St. Louis, where 

 it was discovered by Mr. J. Bradbury, F. L. S. Obs. Root 

 a round tuber, nearly similar to a small turnip. Siem 4 to 

 t3 feet high. Lower leaves thickish, all entire on the mar- 

 gin. Flowers nearly white. The plant not glaucous. 

 'J'his species flowered in the garden of Messrs. Frasers 

 in London, in the summer of 1813. trom roots which I 

 iiad collected at Natchez. 



4. * lanceolata. Herbaceous; stem and leaves on the un- 

 der side glaucous; leaves ovate-lanceolate, acute, nearly 

 entire, and 3-nerved, lower ones petiolate, the upper ses- 

 sile, corymb few-flowered; calix 5-leaved, naked, leaflets 

 flat; flosculi 5. Hab. In Georgia and Florida. — Dr. Bald- 

 '\vyn. Obs. Stem simple and slender, about 3 feet high. 

 Leaves gradually diminishing in size upwards, the larger 

 ones now and then producing 1 or 2 dentures on eiiher 

 side about the middle. Corymb simple. Probably this is 

 the species mentioned in Mlchaux's note under C. atripU- 

 cifolia. Fl. Am. 2. p. 96, as growing in the Illinois lerrito- 

 ly. It approaches very near to the preceding; but is a 

 much smaller plant and glaucous, besides the specific dif- 

 ference. 5. suaveolens. A Senecio. Flowers ochroleucous. 

 Tube of the florets globose at the base. Seed small. 



All the species in this Catalogue, except the last, ap- 

 pear properly referrible to the genus KlemiUy having a 

 simple, equal, 5-leaved calix. At the same time the as- 

 pect of K. poropkyUum appears to be very different. 



546. SPARGANOPHORUS. Gcertner. 



Calix subglobose, imbricate, scales recurved 

 at the point. Bcceptacle naked. Seed crowned 

 with a small subcartila,e:in()us cup. 



Anheteromorphous and probably unnatural genus, con- 

 taining only 3 species. In S. Struchiimi of Jamaica the 

 flowers are glomeratcd, axillary and sessile, with the flo- 

 rets all trifid, and the cup of tiie seed quadricrenste; in 6'. 

 VaiUantii of India, tht; flowers are sessile and lateral, and 

 the cupula of the seed perfectly entire. S. verticillattis, 

 wiiich is aquatic, produces setACeously linear leaves ver-
