COMPOSITACEAE. 



AHicr JacviH L. One of our commonest as well as one of the most elegant 

 of asters and very variable. In the type, the plant is often 3 or 4 feet in

 of the plant. Stem leaves clasping by an auriculate base, the lowermost taper- 

 ing into a winged petiole, the others sessile ; the median lanceolate, often 4 or 

 5 inches long by 1 inch wide, the small sidiulate leaves of the branches and 

 branchlets strongly auriculate and abruptly contracted above the auricles, 

 thence tapering into an accumination. Near Rochester, Oct. 10, 1918, No. 

 5205. 



Aster laevis var. laevigatus (Hooker) A. Gr. Somewhat similar, stem- 

 leave often broadly lanceolate (1^/^-2 inches wide) and thinner, the small leaves 

 of the branches and branchlets subcordate and oblong-lanceolate, not contracted 

 above the base but usually nearly uniform in width for most of their lengths ; 

 I)anicle often .shorter and more ovate. Oxford, Oct. 11, 1917, No. 4721a;

 median stem leaves u.sually broadest at the auriculate base, linear — or oblong 

 — lanceloate, under % incii wide and often (! inches long, some of them fal- 

 cate; small subulate loaves as in the preceding variety. Rochester, Oct. 10, 

 1918, No. 520(;. 



Axtcr laevis var. PANnruATrs n. var. Panicle and subulate leaves as in
