62 MONOECIA— MONANDRIA. Euphorbia. 



Leaves numerous, spretiding in 4 rows, opposite, sessile, oblong-, 

 acute, entire, of a dark glaucous green ; their base heart- 

 shaped ; the lower ones gradually diminishing. Umbel solitary, 

 terminal, large, of 4 repeatedly forked branches. Bracteas 

 heartshaped, entire, tapering to a point. Fl. sessile in each 

 fork, solitary, variegated with yellow and dark purple. Nect. 

 rounded, with blunt horns. Caps, large, smooth. 

 The half-ripe capsules, however acrid, are reported to be sometimes 

 pickled, as a substitute for Capers j but the Caltha, v.3.59, 

 is a better imitation as to outward appearance.

Perennial. August. 



Root long and slender, much branched, spreading widely. Herb 

 glaucous, sm.ooth. Stems about a foot high, ascending, leafy, 

 round, becoming purplish in autumn. Leaves numerous, scat- 

 tered, an inch long, varying in breadth, but of a more or less 

 narrow obovate figure, obtuse with a small point, entire. 

 Umbel of 5, repeatedly forked, branches, and attended by a few 

 scattered branches besides, from the bosoms of the upper leaves. 

 There are 5 leaves at the base of the umbel, like those of the 

 stem. Bracteas rather rhomboid than heart-shaped, pointed. 

 Nect. 4, broadly crescent-shaped. Caps, rough at the angles. 

 Seeds copiously dotted, or reticulated. 



The Greek plant referred to this species in Prodr. Fl. Grcpc.v. 1. 

 327, proves on a more accurate inspection, to differ in having 

 broader leaves, smooth angles to the capsule, and larger seeds, 

 which are neither dotted nor reticulated. Hence this new species 

 has received the name of leiosperma, in Fl. Grcec.v. 5. ol.t. 465.

 Jacquin, and of course by Willdenow, is a mountain species, not
