Oryzopsis asperifolia Miehx. Mountain Rice. 
Occasional in the upland aspen woodlands. Makes good feed, but is 
not common enough to be of importance. Immature fruits collected July 
3, and mature ones later in the month. 
Pine Lake district. Nos. 1787, 1788. 
O. pungens (Torr.) Hitche. 
Occasional in dry, upland woods. Flowers collected June 9 and 17, 
and fruits in early July. 
Along Quatre Fourches river, No. 227; Pine Lake district. Nos. 1785, 
1786. 
Stipa comata Trin. and Rupr. Devil’s Darning-needle, Porcupine-grass. 
Common on the driest parts of the Peace Point prairie, but not found 
elsewhere in the park. It supplies good forage, but its barbed, twisted 
awns become a nusiance in late summer by working their way into cloth- 
ing and into the fur and flesh of animals. In young fruit July 17. 
Peace point, No. 1686. 
S. comata Trin. and Rupr., var. intermedia Scribn. 
Collected only in a bit of clayey prairie on a granite hill in the Peace 
delta, where it was fruiting in early August. 
East shore of lake Mamawi, No. 1687. 
S. Richardsonii Link. Feather-grass. 
Collected only in the Peace Point prairie, where it is fairly common. 
In fruit early in August. 
Peace point, No. 1688. 
Beckmannia Syzigachne (Steud.) Fernald. B. erucaeformis Am. auth., not Host. 
B. haicalensis (W. Kuznetzow) Hulten. See Rhod. xxx, 27 (1928). Slough- 
grass. 
A characteristic grass of wet pond margins in meadow sloughs, and of 
low-lying delta deposits. In semi-dry sloughs it often forms pure stands, 
making a certain amount of forage, but these areas of abundance are 
usually quite small. Collected in flower during the latter half of July, and 
in fruit during August. Its fruits have begun to fall off by August 12. 
East shore of lake Mamawd, Nos. 1639, 1640; along Quatre Fourches 
river, No. 194: Murdock Creek district, No. 1643; Government Hay Camp 
district, Slave river, No. 1644; Peace point, Nos. 1641, 1642; sink-hole 16 
miles east of Moose lake, No. 1645; Sass creek, Russell , No. 20. 
Spartina gracilis Trin. Cord-grass. 
Apparently limited to semi-saline prairies on the Salt Plains, where 
it is fairly common; but on account of its roughness it probably adds 
little value to the forage. Collected in flower August 19. 
Near Heart (Raup) lake, No. 1795; junction of Nyarling and Little 
Buffalo rivers, Rrnsell , No. 62. 
Hierochloe odorata (L.) Wahl. Torresia odorata (L.) Hitehc. Yanlla-grass. 
Common in prairie openings and damp meadows throughout the up- 
land districts, though not sufficiently abundant to afford much pasturage.
