Thalicl rum amel rum 



Stout, ratlur rigid, 3 to 5 feet high, the stem striate, purp- 

 lish, glaucescent: cauliue leaves sessile, compact, the leaflets 

 overlapping one another, barely dark bluish-green above, glau- 

 cescent beneath, of rather firm texture; terminal leaflet usually 

 broader than long, 3-lobed to the middle, the lobes acutely 3 to 

 5-toothed, lateral leaflets not very dissimilar, but smaller, less 

 definitely 3-lobed: panicle of fertile plant rather contracted but 

 large, often more than a foot long, naked except at base: sepals 

 in male plant round-ovate, very obtuse, now and then truncate, 

 and erose across the summit, thin-membranous and purple 

 tinged, not obviously venulose; sepals of female plant truly 

 ovate, at summit acutish, smaller, much more herbaceous, less 

 purplish, not veiny: anthers short, only cuspidate-acute, or per- 

 haps sometimes long pointed: fruit sessile, forming an exactly 

 spherical head about *{> inch in diameter, each achene obliquely 

 round-obovate, compressed, turgid, not ribbed, the sides marked 

 by low sinuous veins running more or less obliquely and occa- 

 sionally coming together to form meshes, the surface otherwise 

 glabrous, glaucescent. 



The range of T. ametrum was correctly given by me, under 

 the name of T. polycarpum^ in my Manual fourteen years ago, 

 as that of the outer or true Coast Range; the completely dis- 

 tinct 7\ caesium occupying the foothills of the interior, either 

 those of the inner Coast Range, or still farther eastward, and 

 this as to middle California only, I am now constrained to say. 



Tlialictrmii meudocinum sp. now 



Evidently a yard or two in height, the stem stout, very 

 erect, terete, faintly striate, as faintly glaucescent, beset with 

 compact sessile leaves, and ending in an ample panicle: leaves 

 of a dark livid green above, quite pale with bloom beneath; 

 leaflets small for the plant, the terminal and lateral more than 

 usually alike, longer than wide, narrowest at the obtuse base, 

 mostly only 3-lobed and not deeply so, the lobes longer than 

 broad, the median one mucronately acute: anthers long, softly 

 aristate-pointed: fruit forming a spherical head less than '_. inch
