the free portion short, triangular, acuminated into an elongated 
setaceous point applied to the petiole ; uppermost leaves opposite, 
close to the head of flowers, with greatly dilated stipules. Flower- 
heads sessile, terminating the stem and branches, at first sub- 
globular, at length ovoid. Calyx-tube 10-nerved, hairy exteriorly, 
and hairy and with a slight callous ring at the throat; teeth very 
slender, subulate-setaceous, with a slender central nerve, the 4 
upper ones about equal to the calyx-tube, the lower one exceeding 
it by one-half, undergoing very little alteration in fruit. Corolla 
generally longer than the calyx. Plant pubescent or sub-glabrous. 
Var. a, sativum. 
T. sativum, Mil. Reich. Fl. Excurs. p. 494. 
Stem erect and robust, furrowed, hollow. Leaflets ovate-oval, 
nearly entire. Stipules very large. Calyx-teeth a little shorter

Stem ascending, rather slender, striated, usually solid. 
Leaflets oval or elliptical-oval, usually denticulate. Stipules much 
smaller than in-var.«. Calyx-teeth about equal to the tube, and 
spreading when in fruit. Corolla longer than the calyx-teeth. 
Var. y, parviflorum. 
Stem arched, ascending. Leaflets elliptical or oval-elliptical,

or exceeding the corolla. 
Var. a, by the borders of fields; escaped from cultivation. Var.

Var. « (which is the cultivated red clover) has the stems 1 to

1 to 2 inches long, those of the lower leaves frequently notched 
at the apex. Stipules of the lower leaves 1 to 1} inch long, the 
upper ones much shorter and broader, whitish and sub-mem- 
branous, with numerous strongly-marked veins, which anasto- 
mose at the margins, adnate for the greater portion of their length,
