118 Rhodora [Тох 
I have now pretty thoroughly explored both states and write with 
knowledge obtained from personal observation. Specimens of this 
Rubus have been widely distributed under the name of R. Canadensis 
by President Ezra Brainerd and Mr. W. W. Eggleston. 'The leaflets 
of this second Linnean specimen on the new cane are also five in 
number, narrow, the middle one ‘ovate with rounded base, the side 
ones oval or slightly ovate, and the basal ones oval. The one fruit 
branch has a rather short but otherwise typical raceme. 
Linnzus may have had both specimens before him, when he wrote 
the above description, but there is positive proof that he had the latter. 
As Dr. Gray has pointed out in Torrey and Gray's Flora of the United 
States in his remarks on R. Canadensis, this latter specimen has one of 
its leaves pressed directly on the top of another, a leaflet covering one 
petiole so that the two leaves would appear to a person with poor eye- 
sight to be one leaf with ten leaflets. Неге Linnæus undoubtedly 
got his idea of ten leaflets. The only ternate leaves on either specimen 
are on the fruit branches. He could get his description of narrow 
leaflets, lanceolate bracts, and linear stipules from either specimen ог” 
from both of them. 
This latter form, the R. Canadensis described by President Brainerd 
in RHopora (2: 23) in 1900, can be found by botanists visiting the 
White Mountains, where it occurs in great abundance in Pinkham 
Notch near the entrance to Tuckerman’s Ravine on the road from 
Jackson to Gorham. Those visiting Lake Willoughby will find that 
though R. Alleghaniensis Porter is common at West Burke, it disappears. 
about three miles up toward the lake where R. Canadensis has the field 
to itself. 
It has been to me a matter of much interest to know the situation in 
Canada — that part from which it is to be presumed the specimens of 
Linnaeus were obtained. Accordingly during the last days of August 
and throughout September, 1907, I searched for Rubus in Canada. 
No light was obtained from examinations made during the time of the 
collections in Montreal and Ottawa, but near the headwaters of the 
Connecticut River in Vermont, New Hampshire and adjacent Canada 
В. Canadensis was abundant. On a trip from Newport, Vermont, to 
Quebec I found in sheltered places near large rivers some R. Alle- 
ghaniensis and also occasionally R. glandicaulis Blanchard, but the 
main high-bush blackberry was R. Canadensis, exactly the same form 
which we have in Vermont.
