Three new Plants from Washington 
By J. S. Corron 
Glyceria latifolia 
Culms 70-120 cm. high, smooth and glabrous; sheaths usu- 
ally exceeding the internodes, loosely embracing the culm, rough ; 
ligule 2-3 mm. long, scarious, truncate; leaves 7 or 8, the blades 
flat, 20-30 cm. long, 6-10 mm. broad, linear, acute, rough on 
both sides : panicle ample, 20-30 cm. long, open; branches in 
twos and threes, spreading, ascending, branching from near the 
middle ; lower branches 10-15 cm. long: spikelets 3 mm. long, 
4-7- usually 5-flowered; empty glumes I-1.5 mm. long, obtuse, 
I-nerved : flowering glumes 2 mm. long, very broad, distinctly 7- 
nerved, scabrous ; palet equalling the flowering glume. 
This species differs from G. nervata Trin. in its much larger 
Size and broader more numerous leaves. It also shows some re- 
semblance to G. Americana but differs from that species in its 
smaller more obtuse glumes and in having a much more coriace- 
Ous palet. 
Specimens examined: Railroad Creek, Okanogan county, 
Elmer, 721 (type); Seattle, Piper; Seattle, Smith, 942; Cas- 
cade Mts., Lyall, 490 ; Stampede Pass, 4 Oct. 1892, Henderson ; 
West Klickitat county, Suksdorf, 1136. 
Astragalus Olympicus 
Perennial, spreading from a stout woody root, the branches 
about 20 cm. long, densely ashy pubescent throughout : leaves 
2-3 cm. long ; leaflets 6-8 pairs, 8-12 mm. long, oblong, sub- 
acute ; stipules membranaceous, triangular, 4 mm. long : peduncles 
two to three times as long as the leaves: raceme about I0- 
©wered: flowers on short pedicels, the bracts linear, acuminate, 
longer than the pedicels: calyx-tube 7 mm. long, pubescent with 
White and black hairs intermixed, the teeth nearly as long as the 
be, equal, acute: corolla greenish-white, tinged with purple, 
adout 10 mm, long: pod t-celled, inflated, membranaceous, 
glabrous, oblong, 20-25 mm. long, 6-12 mm. wide, acute at each 
£nd ; stipe slightly exceeding the calyx tube ; sutures not inflexed.
