200 COMPOSITiE. Solidago. 



gined petioles ; the uppermost oblong or lanceolate, sessile, mostly entire ; 

 racemes loose, paniculate, or rarely somewhat corymbose, sometimes slightly 

 recurvef] ; scales of the nearly glabrous involucre linear-lanceolate ; rays 

 10-12, large; achenia pubescent. 



Open sandy pine woods, near Wilmington, and Lenoir County, North Ca- 

 rolina, Mr. M. A. Curtis! (Florida, Herb. Ra fines que .') May-June. — 

 Stem about 2 feet high, almost villous when young. Kadical and lowest 

 cauline leaves 2-3 inches long, and often 2 inches wide, usually somewhat 

 triple-veined, abruptly contracted into winged or margined petioles which 

 vary in length from 1 to 5 inches ; the other cauline nearly similar but only 

 narrowed at the base and seldom petioled ; the upper very few and reduced 

 in size. Heads middle-sized, about 30-flowered, loosely racemose on the 

 slender naked branches, the summits of which are sometimes a little spread- 

 ing or recurved. Pedicels slender. Rays linear-oblong, golden yellow. 



22. S. TerrfB-Novre: stem erect, smooth, paniculate-corymbose and some- 

 what pubescent at the summit; leaves glabrous; the cauhne lanceolate, 

 tapering to the base, nearly entire ; the lowest and radical spatulate-oblong, 

 tapering into a margined petiole, somewhat serrate-; racemes numerous, 

 short, loose, forming a large expanding and mostly fastigiate compound pani- 

 cle ; heads (small] about 12-fiowered ; scales of the involucre glabrous, ob- 

 long-linear; rays 5-6, small ; achenia nearly glabrous. 



In bogs, Newfoundland, Pi/laie ! MissBrcnton! [in herb. Hook.) — Plant 

 1-2 feet high. Leaves smooth, minutely veiny ; the lowest about 3 inches 

 long, an inch wide near the apex, mostly obtuse ; the uppermost narrow, en- 

 tire. Panicle open, 4-5 inches broad at the summit ; the paniculate irregu- 

 lar racemes more or less spreading, but not secund. Heads as large as in 

 S. stricta; the scales of the involucre membranaceous and much narrower. 

 — The specimen from Miss Brenton consists of the panicle, with only the 

 summit of the stem, the former so much expanded that it was referred by 

 Hooker to S. serotina : but it appears rather to belong to the present division. 



23. S. humilis (Herb. Banks) : glabrous ; stem simple, erect ; radical 

 leaves oblanceolate or spatulate, obtuse, crenate-serrate at the apex, tapering 

 into a petiole ; the cauline lanceolate, acute, narrowed at the base ; the up- 

 permost linear and entire ; raceme simple, or compound and paniculate, 

 elongated, strict; scales of the involucre oblong (somewhat glutinous,) mostly 

 obtuse ; rays C-8, short ; achenia minutely canescent. — Pursh ! jfi. 2. p.

 country between lat. 54° and 64°, Richardson ! Limestone cliffs on the 

 banks of the Onion River &c. Vermont, Dr. Robbins ! 13. Carlton House 

 on the Saskatchawan &c. Drummond! Aug.-Sept. — Stem 6-15 inches 

 high, nearly or quite glabrous, but more or less glutinous, as also the leaves 

 in the fresh plant: the raceme simple and slender, or more or less compound; 

 the branches strict ; the middle-sized heads rather crowded, in (i. much so. 

 Leaves of a firm texture ; the radical often coarsely toothed at the apex; the 

 cauline about 2 inches long, 3-4 lines wide, serrulate above ; the uppernar- 

 rower and entire. — Differs" from S. Virga-Aurea in its more rigid foliage, 

 smaller heads, with the scales of the involucre more appressed, rigid, obtuse, 

 and appearing somewhat glutinous. 



24. S. Virga-Aurea (Linn.) : stem erect, terete ; cauline leaves lanceo- 

 late, tapering to each end, serrate ; the lower elliptical, petioled ; raceme
