ZINNIA 



ZIZANIA 



to 3 ft.: Ivs. ovate or elliptic, clasping, about 1 in. 

 wide: rays becoming reflexed, originally purple or lilac, 

 but now of nearly every color except blue and green; 

 disk originally yellow or orange, but nearly or quite 

 absent in the common double forms: fls. 2-5 in. across. 

 July to Oct. Mex. Single forms are pictured in B.M. 

 527. P.M. 1:223, B.R. 1294 (the last two as Z. violacea). 

 Double forms, F.S. 13:1394, R.H. 1861:251; 1864:331, 

 G. 4 : 138. Pompons in Gn. 48, p. 464 (Liliput) ; 30:270 

 (deceptive as to size), R.B. 20, p. 152. The common 

 species from which most of the garden zinnias are 

 derived. 



cc. Color orange: Ivs. sessile, narrower, lanceolate. 



Haagejlna, Regel (Z. mexicana, Hort.). Fig. 4051. 

 Distinguished from Z. elegans by the orange-colored 

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

 dwarfer, as a rule, and the Ivs. are merely sessile, not 

 clasping. Trop. Amer. Single forms, Gn. 30, p. 270; 

 48, p. 464. Double, Gn. 30, p. 271; 48, p. 464, G. 2:73. 



. 1871, p. 229, A.G. 13:218. Var. stellata, Hort. 

 Florets twisted and acuminate, orange-yellow. This 

 is considered by Robinson & Greenman as a horti- 

 cultural species not certainly distinguishable from Z. 

 angustifolia, in spite of its broader Ivs. 



BB. Achenes longer, narrower, oblong, 3-4 lines long, 

 c. Color of rays yellow; disk yellow. 



pauciflora, Linn. An erect annual: Ivs. lanceolate to 

 oblong-ovate, usually rough: heads yellow, about 1 in. 

 across, with rather broad, spreading, red, purple or 



4051. Zinnia Haageana. 



mostly yellow rays in cult, specimens: plant hirsute, 

 with spreading hairs; somewhat corymbosely branched 

 above: peduncles at maturity enlarged upward and 

 hollow. Mex., Peruvian Andes. 



cc. Color of rays red 



or purple. 



D. Rays suberect or 

 scarcely spread- 

 ing; disk yellow. 



multifldra, Linn. 

 This and the next 

 are included by most 

 writers in Z. panel- 

 flora, but Z. multiflora 

 may be distinguished 

 from Z. pauciflora by 

 the pubescence of the 

 st. being much finer, 

 appressed or rarely 

 spreading, and the 

 rays red or purple, 

 mostly narrow and 

 suberect or scarcely 

 spreading. B.M. 149. 



DD. Rays revolute; disk 



dark-colored. 

 tenuiflSra, J a c q . 

 Fig. 4052. Very dis- 

 tinct by reason of its 

 linear rays which are 

 cardinal-red in color, 

 becoming revolute. 

 It has a dainty fl.- 

 head about 1 in. 

 across hardly com- 

 parable with the 

 showy Z. elegans. 

 This species has been 

 cult, in Amer. but 

 seems to be no longer 

 advertised here. It is referred to Z. pauciflora by most 

 writers, and to Z. multiflora by Robinson & Greenman.

AA. Plant perennial. 



grandiflfira, Nutt. Hardy, low-growing, Colo, peren- 

 nial,, with woody root, erect, stiff, and very rough st. 

 having a shrubby base, linear Ivs., and sulfur-yellow 

 rays which are very broad, almost round in outline: Ivs. 

 less than 1 in. long and 3-nerved. Colo., New Mex,,' 

 A" 2 -' Mex - WILHELM MILLER. 



ZIZANIA (an old Greek name of some wild grain). 

 Gramineae. Tall aquatic grasses with lush sts., long 

 blades, and large terminal panicles of monoecious fls.: 

 spikelets 1-fld., the pistillate upper portion of the pani- 

 cle narrow and appressed, the staminate lower portion 

 spreading; pistillate spikelets long-awned. Species 3, 

 2 in N. Amer. and 1 in N. Asia. 



palustris, Linn. (Z. aqudtica, of Auth., not Linn.) 

 INDIAN RICE. WATER OATS. WATER RICE. WILD 

 RICE. Fig. 4053. Annual: culms tall, as much as 9 ft.: 

 Ivs. broad and flat. Recommended for borders of lakes 

 and ponds. The grain is excellent for fish and water- 

 fowl. Wild rice lakes and ponds are favorite resorts of 

 sportsmen in the fall. Before sowing, put the seed in 

 coarse cotton bags and sink them in water for 24 hours. 

 Sow in water from 6 in. to 5 ft. deep, with soft mud bot- 

 tom, or on low marshy places which are covered with 

 water the year round. In running water, sow as much 

 out of the current as possible. Sportsmen are not gen- 

 erally aware that seed can be obtained in large quan- 

 tities and at a reasonable price from seedsmen. Wild 

 rice is very desirable for aquatic gardens, being one of
