138 Rhodora |JuLy 
commonly 2.5 x 4, 3-3.5 x 5-6, 4 x 7-8, and 4.5 x 7 cm., or on 
sprouts 3 X 8, 4 x 10, and 5.5-6 x 11-12 cm., acute or subcuneate 
at base, short-acuminate from an acute apex or cuspidate from a 
broadly acute to obtuse apex, dark green above, subglaucous to 
glaucous beneath, the yellowish-brown midrib and slender lateral 
veins plane or slightly elevated above, rather strongly elevated be- 
neath, glabrous throughout, or thinly pubescent with shining hairs 
while unfolding. 
Pistillate aments subsessile, with 1-3 small bract-like leaves at base, 
5-6 cm. long; mature capsule conic-rostrate, 9-11 mm. long; pedicels 
1-2 mm. long; style nearly or quite 1 mm. long; stigmas divided, 0.5 
mm. long. 
Variety overi is distinguished from the typical form of the species 
chiefly by the larger, obovate or broadly oval leaves and perhaps 
by longer styles also, though the paucity of material makes this 
uncertain. 
A study of 121 sheets of S. discolor Muhl. in the herbarium of the 
writer and of 135 specimens in the U. S. National Herbarium fails 
to discover any other collections which are referable to this variety. 
Several sterile specimens collected by the writer in the southern parts 
of Vermont and New Hampshire approach it somewhat in the shape 
and size of the leaves. The following specimens represent this variety : 
SourH Dakota: Roberts Co., west shore of Big Stone Lake, at 
Hiawatha Beach, W. H. Over 14483, Aug. 12, 1922 (fol.), May 21, 
"1923 (fruit); C. R. Ball & W. H. Over 2238, Aug. 9, 1923 (fol.), (both 
numbers from same plant and therefore type specimens). "Traverse 
Lake, inside wire fence below the spring on Sisseton road, 2 miles 
northwest of Brown's Valley, Minn., C. R. Ball & W. H. Over 2249, 
Aug. 10, 1923 (foliage and old staminate aments).! 
The type tree is in an old channel on the left (west) of the road at 
Hiawatha Beach, just before it turns west to Art Lake's house, which 
stands several rods farther west. It consists of an old prostrate 
trunk about 8 inches in diameter, partly buried in the mud, and bear- 
ing stout branches about 4 inches in diameter, rooted at the base, and 
reaching a height of 12-15 feet. 
Salix discolor (Ball & Over 2236, 2237) was abundant in the swampy 
ground nearby and one plant of S. missouriensis Bebb was nearby 
! Orer No. 14483 is in herbaria Ball and Univ. So. Dak.; Ball & Over Nos. 2238 
and 2249 have been deposited in herbaria Ball, Can. Geol. Surv., Cornell Univ., 
Field Museum, Gray, Ia. State Coll., Minn. Univ., Mo. Bot. Gard., Rocky Mt. (Wyo.), 
So. Dak. Univ., and U.S. Nat. No. 2238 has been placed also in the herbaria of Calif. 
Acad. Sci., N. Y. Bot. Gard , No. Dak. Agric. Coll., So. Dak. Agric. Coll., and Stan- 
ford Univ.
