The true Hypericum Kalmianum, Linn., here figured, 
which was originally introduced in 1759, has of late years 
_ been almost or quite lost to gardens in this country, the 
plant grown under the name being nearly always //. proli- 
Jicum, Linn., also a North American species. /7. Kalmianuin 
is a native of the Great Lake region of North-Kastern 
America and extends from Ontario and Western New York 
to Illinois, Wisconsin and Michigan. The best-known 
habitat of the shrub is on the banks of the Niagara Gorge, 
but it is now uncommon in nature as well as in gardens. 
For its reintroduction Kew is indebted to Mr. J. Dunbar, 
Assistant Superintendent of the Rochester Parks, N.Y., an 
eager and accomplished student of the North American flora. 
In sending seeds in March 1911, Mr. Dunbar remarked 
that the plants from which they were collected “ were found 
at Rose Hill, Ontario, Canada, on the opposite side of Lake 
Erie from Buffalo, growing in great abundance on the bleak 
Apri, 1913.
