Gi'urrtr Jie.^rri/ili'iH . — Zinnia is a genus of 16 

 ies of annual, perennial and subsliruliby 

 jiiants, mostly Mexiean but ranging from Texas 

 and even Colorado to Chile. They have opyio- 

 site, mostly entire Ivs. and terminal heads of fls. 

 which are peduncled or sessile. Rays pistillate, 

 fertile : disk yellow or purple, its fls. herma- 

 phrodite, fertile: involucre ovate-cylindric or 

 campanulate, the scales in ^ to many series, 

 broad, obtuse or rounded, more or less colored:

 species from which most of the garden Zinnias are de- 

 rived. Pigs. 2794-<J6. Erect annual, a foot or more 

 high, but varying from 3 in. to '.i ft. : Ivs. ovate or ellip- 

 tic, clasping, about 1 in. wide; rays reilexed, originally 

 purple or lilac, but now of nearly every color except 

 blue and green; disk originally yellow or orange, hut 

 nearly or quite absent in the common double forms; 

 fls. 2-5 in. across. July to Oct. Mexico. — Single forms 

 ill. in B.M. 527, P.M. 1:223 and B.R, 15:1294 (the last 

 two as Z. riolaeea). Double forms, F.S. ].3:1394. B.H.

 r>istinguished from Z. eUijinis by the orange-colored 

 fls., which are generally smaller; also the plant is 

 dwarfer, as a rule, and the leaves are merely sessile, 

 not clasping. Tropical America. Single forms, Gn. 30,

 F. 1871, p. 229. A.G. 1892:218. -This is considered by 

 Robinson and Greenraan as a horticultural species not 



certainly distinguishaide from Z. 



luiijiistifoVia in spite of its broader 



leaves. 

 pauciflora, Linn. An erect annual, 



with yellow heads about 1 in across, 



with rather broad, spreading rays. 



Plant hirsute, with spreading hairs;
