through winter). (Natal, from Eurasia) Fig. 1017. 
Var. holosteoIdes Fries (resembling I-Iolostcum). ~ Plant glabrescent or with lines of 
mi nute hairs on the stems; leaves elliptic or oblong, dark green, round-tipped, ciliate - —

5. C. arvense L. (of cultivated ground), Fncim-C. - - Matted or tufted perennial with de- 
pressed, or trailing tough based branches bearing murcescent firm leaves and abundant and conspicu- 
ous axillary fascicles or leafy tufts; flowering branches ascending, simple to freely branched 
0.2-4 dm. high; leaves linear-subulate to narrowly ovate, 0., 5-6.5 cm. long, 0.5-13 mm.' broad’ 
mostly confined to lower two-thirds of branch; bracts scarious-margined; sepals 4. 5-8.5 mm.’ 
long, petals twice or thrice length oj sepals, the broad lobes spreading in anthesis, the claw glabrous- 
capsule cylindric, equaling to much exceeding calyx; seeds reddish, 0.35-0.7 mm. in diameter’ 
the testa close and tuberculate. — A heteromorphous species of cold and temp. reg. of N. and 
S. Hemisph. Ours are tentatively placed as follows: 
a.Internodes of flowering stem villous or pilose with reflexed non-glandular 
hairs. . < b. 
b. Leaves linear to oblong or lanceolate; those of the flowering stems mostly 
0.5-3.5 cm. long and 0.5-4 (-5) mm. broad, tapering to base C. arvense 
7 t i . (typical) . 
o.Leaves lanceolate to ovate, those of the flowering stems often more rounded 
at base, mostly (2-) 3-6.5 cm. long and (3—) 5-13 mm. broad. 
Stems and leaves more or less pilose or the leaves glabrous above, their 
blades mostly lanceolate, up to 0.5 cm. long and 3-10 mm. broad. . Var. villosum. 
Stems and leaves very densely velvety- or tomentose-villous with long 
white pubescence; leaves oblong-lanceolate to lance-ovate, 2-4 cm. 
long and 0.8-1. 3 cm. broad V ar. villosissi- 
mum. 
a. Internodes all glandular-hispid, the gland-tipped short hairs often intermixed 
with glandless ones. . 
Var. viscidulum. 
arvense (typical). Plant compact or lax; leaves densely pilose or the upper surface 
glabrate. (Inch C. ccvmpestre and several other proposed spp. of

Var. vill6sum (Muhl.) Rollick & Britt, (long-hairy). — Mostly

C. toment6sum L. (tomentose), Snow-in-Summer, 
a depressed and matted perennial with stems, leaves 
and calyx densely white-woolly or tomentose, is cult, 
in rockeries and borders, and sometimes spreads to 
wild habitats. (Introd. from Eurasia)
