RypBERG: Notes ON ROSACEAE 361 
Fragaria grandiflora Ehrh., the ‘pine strawberry,” is a native 
of South America. It is often hard to distinguish it from F. 
Grayana, but the petals are larger, usually over 1 cm. long, the 
sepals ovate or ovate-lanceolate, the achenes set in shallower pits, 
and the leaflets thicker. It often resembles closely F. chiloensis 
but lacks the characteristic tomentum of the lower surface of the 
leaflets. In cultivation are found many crosses between this 
species and F. chiloensis and F. virginiana. In the New York 
Botanical Garden herbarium there are the following specimens 
of F. grandiflora, which were collected far away from dwellings 
and which were well established at the localities: 
New York: Roadside in woods between Twin Lakes and 
Mountain Lodge, Adirondack Mountains, July 4, 1906, Rydberg 
7842. 
British CoLuMBIA: Trail, May 19 and June 13, 1902, J. M. 
Macoun 63776 and 63777. 
KENTUCKY: Vicinity of Mammoth Cave, May 1899, Dr. E. 
Palmer. 
At the same station where the writer collected F. grandiflora, he 
found also the white-fruited F. vesca, and the ordinary F. virginiana, 
with a white-fruited form of the latter. The white-fruited F. vesca 
is not uncommon in certain localities from northern New York 
and Connecticut to West Virginia and eastern Ohio. It is most 
common in the mountains of Pennsylvania. It is strange that 
this form should be common and apparently native in a region 
where the typical F. vesca is very rare and is found apparently 
only as an escape from cultivation. It is questionable if it should 
not be regarded as a native geographical species even if it originally 
mutated from F. vesca. It is not a form of the native F. americana. 
The white-fruited form of F. virginiana collected in the Adiron- 
dacks by the writer and mentioned above, is very interesting. 
As the white-fruited F. vesca and the ordinary red-fruited F. 
virginiana were common along the road and growing together, 
these white-fruited specimens of F. virginiana might be hybrids 
between the two. They were typical F. virginiana, however, 
in every respect, even to the pitted fruit, except that the latter 
was white.
