504 COMPOSIT.1:. SoLiDAGO. 



mont ! — Two states were collected ; the one connecting this variety with var. 

 minuta and var. alpina ; the other larger, with a stout glabrous stem. 



25. S. ihyrsoidea. — Abundant in woods from the base of the Notch to the 

 alpine region of the White Mountains of New Hampshire, and also sparingly 

 found on the exposed alpine summits, far above the limit of trees I Also 

 Indian Pass, and sides of Mount Marcy, Northern New York, Mr. Macrae! 

 Plant 1-3 feet high, mostly with an elongated virgate or thyrsoid leafy ra- 

 ceme. — Add syn. S. Virgaurea, Pursh ! fl. 2. p. 542. (Labrador, Kohl- 

 meister !) 



26. iS. glomerata (Michx.). — Our plant is certainly the species of Michaux, 

 the specimen of his herbarium having been compared with ours by Mr. 

 Decaisne. The state with a strict glomerate inflorescence, as described by 

 Michaux, has recently been collected on the ^jlack Mountain, North Caro- 

 lina, by Mr. Buckley. a '. 



31. S. Riddellii. — Add syn. S. amplexicaulis, iWariens / in hull, acad.- 

 Brux. 8 (1841),^. 66. 



39. iS. neglecta, is not found in N. Carolina ; the specimens received from 

 thence prove to have been collected in Massachusetts. It extends northward 

 to Montreal, Mr. Macrae ! 



40. S. patula. — The phrase ' leaves very scabrous above,' was acciden- 

 tally omitted in the specific character. 



49. S. amplexicaulis. — The reference to Martens under this remarkable 

 species must be erased, his S. amplexicaulis being S. Riddellii, as above 

 noted. 



SILPHIUM, p. 274. 



3. S. pinnalifidum (Ell.) must be reduced to a variety (/3. pinnatifidum) 

 of S. terebinthinaceum ; Mr. Sullivant having noticed that they pass into 

 each other, as we suspected, like the varying forms of S. compositum. In 

 specimens from Alabama, collected by Mr. Buckley, the leaves vary from 

 sinuate-toothed to somewhat bipinnatifid. 



IVA, p. 286. 



4. /. microcephala. — Middle Florida, Dr. Chapman! — Heads larger than 

 in the original description, 6-8-flowered. Leaves filiform-linear, often an 

 inch long, with smaller ones fascicled in their axils, punctate, and, like the 

 branches, &c. sparsely strigose with minute hairs. 



HELIANTHUS, p. 318. 



13. H. occidentalis (Riddell). — Add var. 



y. Dowellianus : nearly smooth and glabrous ; stem often stout (2-5 feet 

 high) and more leafy, simple or corymbose-paniculate at the summit ; leaves 

 larger, varying from broadly ovate, or even slightly cordate, to oval-oblong. — 

 H. Dowellianus, M. A. Curtis! in Sill. jour. 44. p. 82. 



Around Franklin, Macon County, North Carolina, Mr. Curtis! Mr. 

 Buckley ! with var. P., which connects it to the ordinary state of the species. 

 — Limb of the lower leaves 3-6 inches in length, 2-5 broad, rather coria- 

 ceous, in outline, &c., resembling those of some forms of H. atrorubens. 

 Heads and flowers as in the ordinary form of the species.
