i,ooo and 1,500 feet above sea-level. The principal locality 

 visited on the Yukon River was a gravel hillside, sloping^ towards 

 the south, within a short distance of the town of Dawson. Another 

 locality was a rocky hill, also facing- the south, a couple of miles 

 further up the valley. The localities on Bonanza and Hunker 

 creeks were either on the swampy flats or on the swampy hill- 

 sides. Chandindu River was visited once, on July 13th, and the 

 plants, as labelled, were collected either on the wide swampy flat 

 in the bottom of the valley, on a grassy hillside on the north side 

 of the valley, or on a sandy bar at the mouth of the river where it 

 joins the Yukon River. Forty-mile River was visited for a few 

 days between June 29th and August 8th, and the plants were col- 

 lected close to the banks of the river as we ascended and descend- 

 ed in a canoe."
