ZINNIA 



somewhat corymbosely branched above: peduncles at 

 maturity enlarged upwards and hollow. Mexico, Peru- 

 vian Andes. 



multifldra, Linn'. This and the next are included by 

 most writers in Z.pauciflora, but Z. multiflora may be 

 distinguished from 

 Z. pauciflora by the 

 pubescence of the 

 stem being much 

 finer, appressed or 

 rarely spreading, and 

 the rays red or pur- 

 ple, mostly narrow 

 and s ub erect or 

 scarcely spreading.

tenuifldra, J acq. 

 Fig. 2798. Very dis- 

 tinct by reason of its 

 revolute, linear rays 

 which are cardinal- 

 red in color. It has 

 a dainty flower about 

 1 in. across hardly 

 comparable with the 

 showy Z. elegans. 

 This species has 

 been cult, in America 

 but seems to be no 

 longer advertised 

 here. It is referred 

 to Z. pauciflora by 

 most writers, and to 

 Z. multiflora b y

grrandifldra, Nutt. 

 Hardy, low-growing, 

 Colorado perennial, 

 with woody root, 

 shrubby base, linear 

 lvs. and sulfur-yel- 

 low rays which are 

 very broad, almost 

 round in outline. 

 Lvs. less than 1 in. 

 long and 3 -nerved.

ZIZANIA (an old Greek name). Gramineo?. A single 

 species of annual swamp grass found in northern N. A. 

 and northern Asia. Spikelets 1-fld., monoecious, in 

 large, terminal panicles, the pistillate upper portion 

 narrow and appressed, the staminate lower portion 

 spreading: pistillate spikelets long awned. The plant 

 is a stately and graceful grass, deserving to be better 

 known. 



aquatica, Linn. Indian Rice. Water Oats. Wild 

 Rice. Culms tall, as much as 9 ft. : lvs. 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 seeds in coarse cotton bags and 

 sink them in water for twenty-four hours. Sow in water 

 from 6 in. to 5 ft. deep, with soft mud bottom, or on low 

 marshy places which are covered with water the year 

 round. In running water, sow as much out of the cur- 

 rent as possible. Sportsmen are not generally aware 

 that seed can be obtained in large quantities and at a 

 reasonable price from seedsmen. Wild Rice is very de- 

 sirable for aquatic gardens, being one of the handsom- 

 est of tall hardy grasses for the margins of ponds.

ZlZIA (I. B. Ziz. Rhenish botanist). CmbelUfera. A 

 genus of three species of hardy perennial North Ameri- 

 can herbs 1-2% ft. high, with ternate or ternately com- 



pound leaves and compound umbels of yellow flowers. 

 The genus has no horticultural status, the two follow- 

 ing species being advertised only by collectors of native 

 plants. For full account, see Britton and Brown's Illus- 

 trated Flora, Coulter and Rose's Monograph of the 

 North American Umbelliferffi, Contrib. U. S. Nat. Herb. 

 7:90 (1900), and Manuals. Zizias are mostly referred 

 to Thaspium by previous botanists, but the authors 

 cited above retain it as a separate genus mainly on ac- 

 count of the wingless fruit. 



A. Bays of umbels 9-25, stout, ascending. 



aurea, Koch. Early or Golden Meadow Parsnip. 

 Height 1-2 J-2 ft.: basal and lower lvs. 2-3-ternately com- 

 pound: upper lvs. ternate: fr. oblong, 2 x \% lines. 

 April-June. Fields, meadows and swamps, New Bruns. 

 and S. Dak. to Fla. and Tex. B.B. 2:534. 



AA. Bays of umbels 2-12, slender, diverging. 



Bebbii, Britton. Distinguished from Z. aurea by the 

 rays and by the fr., which is oval or broader, 1-1K lines. 

 May. Mountain woods, Va. and W. Va. to N. C. and Ga.

ZlZYPHUS (from Zizouf , the Arabian name of Z. Lo- 

 tus). Bhamnaeea>. Jujube. Deciduous or evergreen 

 shrubs, or sometimes trees usually with prickly

branches, alternate, short-petioled, 3-5-nerved, entire or 

 serrate lvs. and small greenish or whitish flowers in 

 axillary cymes followed by drupe-like sometimes edible 

 fruits. They are not much cultivated in this country
