 acute at each end, remotely serrate ; the radical and lower cauline ones broader, tapering 

 into a petiole ; heads glomerate, or in short racemes from the axils of the upper leaves, and

Stem 2-3 feet high, often purplish, clothed with villous hairs, sometimes a little branching 

 at the summit. Leaves pale green, more or less hairy on both sides ; radical ones 3-5 

 inches long and 1-2 inches wide, the petiole long and narrow ; upper cauline sometimes 

 entire, sessile, but acute at the base. Heads of flowers rather large, the glomerules forming 

 an elongated compound spike or terminal leafy raceme. Involucre oblong, the scales oblong- 

 lanceolate, with greenish midrib and tips, the margin scarious and minutely ciliate. Rays 

 rather short. Disk-flowers 9 - 14. Achenia smooth, narrowly sulcate. 



Woods, copses, etc. ; frequent. Fl. August - September. 



3. SoLiDAGO LATiFOLiA, Linn. Broad-leaved Golden-rod. 



Stem angled and usually flexuous, smooth ; leaves broadly ovate or oval, coarsely and 

 acutely serrate-toothed, conspicuously acuminate at both ends, or abruptly attenuate into a 

 short petiole, mostly hairy on the veins underneath ; heads in (usually short) axillary racemes 

 or clusters, and racemose or paniculate at the summit of the stem ; scales of the involucre 

 nearly smooth, obtuse ; achenia silky-pubescent. — Linn. sp. 2. p. 789 ; Torr. compend.

 shorter, but sometimes longer than the leaves. Peduncles pubescent. Exterior scales of the
