(.Root with red shoots. Stem one and a half to two feet high. Stigma four 
lobed, by which it is essentially distinguished from E. roseum. E. Bot. 
E.) Stem cylindrical, upright, reddish, very soft, somewhat downy. 
Leaves smooth, finely toothed, very soft, especially underneath, with a 
down just perceptible. Linn. Leaves spear-egg-shaped. Petals pale 
purple, veined with deeper purple lines; sometimes white. (Graves 
remarks that a very small proportion of the innumerable seeds vegetate, 
they being peculiarly liable to the ravages of a minute insect which per¬ 
forates just below the plume. E.) 
Var. 2. Leaves three and four at a joint. 
(Broad Smooth-leaved Willow-herb. Welsh: Helyglys llyfn llydan- 
ddail • E.) Woods, hedge-rows, shady lanes and moist meadows, in a 
gravelly soil, and sometimes on walls in courts, (or on cottage roofs. E.) 
P. July. 
E. tetrago'num. Leaves spear-shaped, finely toothed, sessile, the 
lowermost opposite : stem quadrangular: (summit entire. Curt.)

(May be distinguished from E. palustre by the quadrangular ribs at unequal 
distances from each other on the stem. E. Bot. E.) Stem upright. 
Leaves smooth; sometimes all strap-spear-shaped. Woodw. Blossom 
purplish red ; (plant twelve to eighteen inches high. E.) 
Square-stalked Willow-herb. (Welsh: Helyglys pedrongl. E.) 
Marshes, and sides of rivulets and ditches. P. July. 
(E. ro'seum. Leaves stalked, ovate, toothed: stem erect, with four 
obsolete angles: stigma undivided. 
E. Bot. 693. 
Herbage not unlike E. montanum, but the stem is more branched, and at 
the upper part obscurely quadrangular. Leaves smooth, thin and deli¬ 
cate ; upper ones alternate. Flowers paler than the preceding; petals 
streaked at the base. Stigma small, club-shaped and undivided, by 
which it essentially differs from E. montanum, and agrees with tetragonum. 
Yet it is too abundantly propagated by seed to be supposed a mule pro¬ 
duction. Sm.
