276. Epilobium obscurum (Schreb.) Roth var. c. herminium Sampaicv 

 1. C, p. 187. 



Planta debil, de caules finos, simples ou divididos na base; folhas 

 pequenas, oppostas, glabras, ovaes ou ovaes-lanceoladas, arredondadas na 

 base, quasi rentes e inteiras ou muito obscuramente denticuladas; flores 

 com as petalas de 7 — 9 mm de comprido.

Caules notavelmente ramosos desde a base, com 10 — 22 cm de com- 

 prido; folhas bem desenvolvidas e muito pecioladas; fructos bastante 

 pubescentes, mesmo na maturacao. 



Portugal: Serra da Estrella: Covao da Metade, Fonte do Canariz e

 Perreira!). 



278. Aster microlonchus Edw. L. Greene in Ottawa Naturalist. XV 

 (1902), p. 278. 



Stems about two feet high, very erect, divested of all lower leaves 

 at flowering time, parted from below the middle into numerous leafy and 

 flowering branches forming a somewhat contracted and subpyramidal 

 panicle; the reddened bark of stem and branches glabrous or obscurely 

 pubescent: leaves of the panicle narrowly lance-linear, two inches long 

 more or less, entire, sessile by a broad more or less perceptibly auricled 

 base, thin, delicately scaberulous above, scabrous on the margin, glabrous 

 beneath, marked by a delicate midnerve only, spreading or slightly de- 

 flexed: heads few and subracemose on the branches, or solitary at the 

 ends of them, nearly and inch broad measuring the rays, the involucre 

 short-campanulate, its bracts in about three series, narrowly spatulate- 

 lanceolate, scaberulous, at least marginally and spreading or recurved at 

 tip: rays many and showy, apparently pale violet. 



British Columbia: The types of this strikingly handsome new 

 Aster are Mr. Macoun's number 26384 and 26385 from the Chilliwack 

 Valley, collected 18 Aug,, 1901. 



Its immediate allies are A. longifolius Lam., A. hesperius Gray, and 

 A. ensatus Greene. Prom all of these it differs not only in aspect, but 

 in its foliage which, though sensibly roughened above, is yet of a texture 

 so delicate that all the lower and properly cauline ones fade and fall 

 before the time of flowering. It is perhaps more elegant and beautiful 

 than any of its near relations, and rather smaller in stature, though 

 growing in generous soil, and a climate abundantly moist and not severe. 



279. Gnaphalium Macounii Greene, 1. c, p. 278. 



Apparently biennial, the stems rigidly erect, about two feet high, 

 rather loosely leafy and clothed with a somewhat hirsute and viscid 

 glandular-pubescence: leaves narrowly oblanceolate. acute, 3 inches long, 

 the upper decurrent, all white-woolly beneath, light green and merely 

 glandular-pubescent above; branches of the subpyramidal close panicle
