22 Rhodora [FEBRUARY 
The following synopsis will serve to indicate the relation of C. 
Grimesti to other groups in the genus. 
a. Corolla normally white, rarely and exceptionally pink; 
bracts usually not evidently ciliolate; leaves short- 
petioled or sessile; pubescence, if present, of short, com- 
paratively stiff, mostly unicellular hairs............... C. glabra. 
C. Cuthbertit. 
a. Corolla pink or purple; bracts usually evidently ciliolate. b. 
b. Leaves long-petioled; plant (except the bracts) glabrous 
or sparsely pilose with weak, pluricellular hairs.......... C. obliqua. 
C. Lyoni. 
b. Leaves closely sessile; stem and midribs of the leaves 
beneath minutely granular-puberulent................. C. Grimesü. 
GNAPHALIUM OBTUSIFOLIUM L., var. micradenium, n. var., plerum- 
que gracile, caule breviter glanduloso-puberulo non tomentoso; foliis 
linearibus acutis vel obtusiusculis, 1.8-5:3 cm. longis, 1.5-7 mm. 
latis, rarius majoribus et tum oblanceolatis, subtus tomentosis supra 
glandulosis; involucri squamis plerumque acutis. 
Usually slender; stem glandular-puberulent, not tomentose; leaves 
linear, acute or obtusish, 1.8-5.3 cm. long, 1.5-7 mm. wide, rarely ex- 
ceeding these dimensions and then oblanceolate, the lower surface 
tomentose, the upper glandular; scales of the involucre mostly acute.

The plant here described is apparently the northern and more 
inland representative of var. Helleri (Britton) Blake, which seems 
to be confined to the coastal plain from Virginia to Florida. In most 
of the specimens seen, the small, narrow leaves are very characteristic, 
increasing very little or not at all in size even when the stem attains 
a height of 4.5 dm. as in the Grimes specimen. This foliar character, 
though generally useful, is more or less inconstant, even in the same 
colony. 'The characters of the glandular pubescence, however, 
appear to correlate perfectly with natural geographic ranges.
