SECTION IDAENTHI 
R. coreanusXR . strigosus horticultural variety Newman. This cross was made 
by the junior author at the Bell Horticultural Field Station and the buds taken from 
a selected bush. The R. coreanus parent of this hybrid was grown from seed secured 
from Kew, England, but itself seems to be a hybrid, R. coreanusXR • biflorus. 
R. innominatus S. Moore. The plants of this species were propagated from plants 
grown by the late Dr. Walter Van Fleet, presumably from seed sent by E. H. Wilson 
from China. 
R. adenophorus Rolfe. The plants of this species were obtained from the Office of 
Foreign Seed and Plant Introduction, United States Department of Agriculture, 
under No. 52939. 
R. innominatusXR- idaeus horticultural variety Superlative. The plant from 
which buds were taken was one of several of this cross made by the junior author 
at the Bell Horticultural Field Station. 
Rj innominatusX(R- idaeusXR • strigosus) horticultural variety Cuthbert. Horti¬ 
cultural variety Van Fleet. This hybrid was made by the late Doctor Van Fleet 
at Chico, Calif., and the plants grown from seed at the Bell station. 
R. occidentalism Horticultural variety Cumberland. This was originated by David 
Miller of Camp Hill, Pa., and introduced in 1898. 
Horticultural variety Farmer (Plum Farmer). This was found in a shipment 
of another variety received by L. J. Farmer, Pulaski, N. Y., and introduced by him 
in 1895. Farmer, as an early sort, and Cumberland as a late variety are the leading 
black raspberries grown in the United States. 
R. occidentalisXR . idaeus. Horticultural variety Gregg XWisbeck. The buds 
were collected from one of several seedlings of this cross made by the junior author 
at the Bell station. 
Horticultural variety Royal. This variety was originated in Indiana by L. H. 
Gerton, and was introduced by L. J. Farmer, Pulaski, N. Y., in 1909. 
{R. occidentalisXR • idaeus)Xstrigosus. Horticultural variety Cardinal. This 
variety originated on the place of A. H. Griesa, Lawrence, Kans., in 1888, apparently 
from seed of the Shaffer. Because of its glandular hairy inflorescence it is considered 
a cross of the Shaffer with a variety of R. strigosus ( 4). 
Horticultural variety Royal X Newman. The material for study was taken from 
a plant growing at the Bell station which was one among the many crosses of this 
parentage made by the junior author. 
R. occidentalisXR • strigosus . Horticultural variety GreggXKing. This material 
for study was taken from one plant, which was selected for its good fruit, from a large 
number of plants of this cross made by the junior author, at the Bell station. Most 
seedlings of this cross were partly sterile, setting but few drupelets to each flower. 
This seedling was selected as the best and its pollen count showed a notably high 
percentage of good pollen grains. The seed parent was a variety of ( black raspberry 
resembling Gregg but concerning the identity of which there was some question. The 
abundant glandular inflorescence clearly distinguishes these crosses from the Royal 
and the Gregg XWisbeck. 
R. idaeus. Horticultural variety Lloyd George. This variety was found wild and 
introduced by J. H. Kettle, Corfe Mullen, Winborne, Dorsett, England, in 1920. 
Horticultural variety Magnum Bonum. This old variety of Europe was intro¬ 
duced into America about 1840. It differs markedly from the other European rasp¬ 
berries which we have studied. The turions are densely covered with glandular 
bristles and it resembles mountain and maritime forms. 
R. idaeusXR . strigosus. Horticultural variety Cuthbert. This variety originated as a 
chance seedling in the garden of Thomas Cuthbert at Riverdale, N. Y., about 1865 
growing near plants of the Hudson River Antwerp, a variety of R. idaeus. It is, 
therefore, considered a hybrid of R. idaeusXR. strigosus. 
Horticultural variety Marlboro {Abundance, Laxton's Abundance , Perfection of 
England). The material used was gathered from plants received as Laxton’s Abun¬ 
dance from Laxton Bros., England, a variety which was determined to be identical 
with Marlboro by Grubb (p). This is confirmed by our examination. Marlboro was 
originated by A. J. Cay wood, Marlboro, N. Y., as a cross of Highland Hardy, and a 
seedling from English Globe and the Hudson River Antwerp (5), and introduced in 
1884. Highland Hardy is supposed to be a variety of R. strigosus. November Abun¬ 
dance is probably a distinct sort, having originated in England.
