1. Z. Californica, Tresl. !More or less villous and often tomentose, much 

 branched, the as('eudiiig or dec\uubent stems a loot or two long: leaves narrowly 

 lanceolate to ovate, \ to 1^ inches long, acute, entire or denticulate: llowers 10 to

In dry locaUties from Napa and Plumas counties to S. California and Northern Mexico, and 

 eastward of the Great Basin I'loni N. AV. Wyoming (Parry) to the Wahsateh (IViUson) and New 

 Mexico {WrUjIU) ; the variuly in S. California. Very variable in its foliaj^e and puhescence, and 

 in its llowers, which are broadly or narrowly funnelfonn, more or less deeply colored, and with 

 the style and stamens more or less exserted. 



4. EPILOBIUM, Linu. Willgw-IIeub. (By W. Baubey.) 



Tube of the calyx not conspicuously prolonged beyond the ovary ; the limb

spreading, deciduous. Petals 4, spreading or somewhat erect. Stamens 8, the 4 



alternate ones shorter; anthers elliptical or roundish, lixed near the middle. Stigma 



oblong, clavate, or with 4 spreading or rovoluto lobes, ('apsule linear, 4-sided, 



4-celled, 4-valved. Seeds numerous, ascending ; the summit furnished with a coma or 



tuft of long hairs. — Perennial or annual herbs ; leaves alternate or oi)posite, nearly 



sessile, denticulate or entire, often fascicled ; flowers rose-colored, purple or white, 



very rarely yellow. 



A genus of about 100 species, inhabiting the temperate and colder regions of the globe, many 

 of them very variable, and the number greatly multiplied by authoi-s.
