multifldra, Linn. This and the next are included by 

 most writers in Z.paueiflora, but X. mnltiflora may l>e 



distinguished from 

 Z. panel flora by tin- 

 pubescence of the 

 stem being much 

 finer, appressed or 

 rarely spread ing, and 

 the rays red or pur- 

 ple, mostly narrow 

 and suberect or 

 scarcely spreading.

tenuif lor a , J a c q . 

 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 /.. cli'i/i. /*. 

 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. mnltiflora by 

 Robinson and Green-

 Hardy, low-growing, 

 Colorado perennial, 

 with woody root, 

 shrubby base, lineai 

 Ivs. and sulfur-yel- 

 low rays which are

 round in outline.

ZIZANIA (an old Greek name). Gramlnece. 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.: 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 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.
