In woods, groves, and thickets, common. 



Perennial. March, April. y, \ 



Root branching, knotty, somewhat \voodY^-rMe.rb milky, soft and 

 downy. Stems several, rather shflEby, biennial, simple, leafy, 

 round ; purple in the lower part when stripped of its leaves -, 

 many-flowered above. Leaves scattered, numerous, spreading, 

 stalked, entire, oblong or obovate, obtuse. Umbel usually of 

 5 or 6 simply forked branches, accompanied beneath by nume- 

 rous similar branches, solitary from the bosoms of the paler, or 

 purplish, more remote, upper leaves. Bracteas yellowish, pale, 

 combined, rounded, pointless, nearly or quite smooth. Nect. 4, 

 crescent-shaped, acute, yellow. Caps, elliptical, smooth. 



Sometimes each bractea has a minute point. On this Linnaeus 

 founded the character of his original E. sylvatica, which how- 

 ever is a very trivial variety. What he afterwards took for syl- 

 vatica is segetalis. For ascertaining this I am obliged to my 

 friend Prof. DeCandolle, and at his persuasion I do not scruple 

 to unite amygdaloides and sylvatica, whose descriptions and 

 figures are generally much confounded by authors. Haller went 

 far enough to discover this j but declined pursuing the investi- 

 gation of numerous species, not natives of either Switzerland or 

 Britain, involved in the confusion. 



13. E. Characias, Red Shrubby Spurge. 



Umbel of numerous forked downy branches ; with many 

 axillary crowded stalks beneath. Bracteas somewhat 

 pointed, perfoliate. Leaves lanceolate, downy. Capsule 

 hairy.
