458 ^ SYNGENESIA [Astkboili* 



flowers rather large, in sccund spreading paniculate racemes ; branches and perf. 

 icels roughish pubescent ; involucre minutely pubescent, green, the leaflets lance* 

 oblong, keeled, rather acute, sometimes obtuse ; rays oblong, middle-sized. Ak. 

 tnes slightly puberulent and bristly, 



Hab. Low grounds ; thickets, Sec frequent. Fl. August— Sept. Fr. October. 



Obs. This is the S. patula, of Muhlenberg's Herbarium ; and is remarkable for 

 the shagreen-like roughness on the upper surface of the leaves, —a circumstance 

 not noticed in any description which I have seen. It is the plant intended by s, 

 tcabra, in my Catalogue,— and is there erroneously and unaccountably described 

 as having the leaves "scabrous beneath. 11 



9. S. aiig vta, Jlit. Stem smooth ; leaves elliptic-lanceolate, acu- 

 minate, acutely and unequally serrate, smooth, the radical ones spatu- 

 late-ovate ; racemes paniculate. Beck, Bot. p. 190, 



SiiARr (notched) Solidago. 



fiNfll 2 to 3 feet high, sulcate-striatc, smooth, simple, or virgately branched. 

 Radical leaves nearly of the size and form of those in the preceding species, but 

 more sharply serrate, thinner, and smooth on both sides ; stem-leaves gradually 

 smaller, elliptic-lanceolate, acuminate, sharply serrate, narrowed at base, subscs- 

 sile, tko uppermost ones lanceolate, entire,— all thinnish, chartaceous, smooth, 

 and minutely scabrous on the margin. Heads of flowers rather large, racemes 

 secund, in an elongated and rather slender panicle ; branches and pedicels some- 

 what pubescent; involucre smoothish, the leaflets lance-oblong, scarious on the 

 margin, and very minutely ciliatc-serrulate ; rays spatulate-oblong, middle-sized. 

 Akenes nearly smooth, or very minutely puberulent. 



Hab. Low, shaded grounds ; Brandy wine : frequent. Fl. August. Fr. Sept. 



Obs. This was collected in 1829, by D. Townsknd, Esq. It has considerable 

 general resemblance to the preceding ; but is a more delicate plant, with the 

 leaves thinner, more acuminate, very smooth, and sharply serrate. 



•(■ f Racemes erect. 



10. S. BicoLon, L. Stem and leaves hairy; leaves elliptic-lanceo- 

 late, acute, the lower ones serrate ; racemes erect ; leaflets of the in- 

 volucre obtuse. Beck, Bot. p. 191. 

 Mso, S. erecta. Florul. Cestr. p. 89. Not of Pursh, JVutt. Ell. &c. 



Two-colored Solidago. 



Stem 1 to 3 feet high, striate, hairy, mostly simple, sometimes branched at sum- 

 mit, with the branches leafy. Radical leaves 2 to 6 inches long, and 1 to 2 

 inches wide, elliptic-oblong (the young ones often spatulate), acute, serrate, 

 tapering at base to a petiole nearly as long as the leaf; stem-leaves elliptic-lance. 

 olate, gradually smaller, and less serrate as they ascend, the upper ones entire, 

 all hairy, tapering at base, sessile, or subsessile. Heads of flowers rather large, 

 in short axillary racemes, forming altogether a kind of spike, or long dense 

 compound leafy terminal raceme (when the stem is branched at summit, forming 

 a terminal raceme on each branch); involucre smoothish, the leaflets oblong, 

 m »stly obtuse, scarious on the margin, and minutely ciliate-serrulate, sometimes 

 a little spreading at apex; rays middle-sized, whitish, or ochroleucous. Akenes 

 striate, sparsely pubescent, finally smooth. 



Hab. Woodlands, clearings, & low grounds: frequent. Fl. Aug- Sept. FV. Octo. 



Obs. The S. erecta, of my Catalogue, is nothing but a variety of this.
