R. strigosus Mchx. Wild plants from Hebron, N. Y. In September, 1920, selec¬ 
tions were made of bushes fruiting freely in the fall on turion tips. These were 
transplanted to the collection of the Bell Horticultural Field Station. 
Horticultural variety Eaton. Found as a chance seedling at Cambridge City, 
Ind., in 1885. Its glandular inflorescence refers it to R. strigosus. 
Horticultural variety King. The history of this variety is not entirely 
clear. It is widely grown in the upper Mississippi Valley States. The buds used 
were from plants of this variety secured from Michigan. It is supposed to be the 
Thompson's King sent out by the Cleveland Nursery Co. of Rio Vista, Va., in 1892, 
which variety was grown from seed of Thompson by T. Thompson of Richmond. 
Beach, in 1895, however, states of this variety, “Canes vigorous, show evidence 
of Idaeus parentage” ( 2 , p. 204 ). King, as grown to-day, does not show evidence of 
R. idaeus parentage, except perhaps in that a large percentage of its progeny are 
more or less infertile, but it has the, glandular inflorescence, the thin leaves, and 
light-red fruit of R. strigosus and is very hardy. Over 100hybrids with a black rasp¬ 
berry and many hundred other hybrids and crosses with it made by the junior 
author fail to show characteristics of R. idaeus but do show characteristics of R. 
strigosus and it is classified accordingly. 
Horticultural variety Newman. This variety was grown from seed of Eaton, 
by C. P. Newman, La Salle, Quebec, and was introduced by the Provincial Gov¬ 
ernment of Quebec, Canada, in 1921. Its hardiness and light red fruit refer it to this 
species. Newman states that the pollen parent may have been King. 
Horticultural variety Ranere (St. Regis). The Ranere was found wild near 
Hammonton, N. J., by A. Ranere and was extensively grown by him and others 
several years before 1910 when it was introduced under the name “St. Regis.” It 
is densely glandular, hairy, very hardy, has thin leaves and light red fruit, and is 
referred to R. strigosus (6). 
Table I shows that all raspberries examined cytologically can be sepa¬ 
rated into two classes, those with seven haploid chromosomes, and those 
with more than seven. 
Such a division also separates all species into two groups based on the 
distribution of the chromosomes during the reduction divisions of the 
pollen mother cell. The diploid species, that is, those showing seven 
bivalent or haploid chromosomes just previous to the first reduction 
division, have the somatic or univalent chromosomes pairing very 
promptly in the prophase of the first reduction division, and these bival¬ 
ent chromosomes divide regularly and promptly in both the first and 
second divisions. Such a division gives a quantitatively equal distri¬ 
bution of all chromatin material to the four daughter nuclei, and conse¬ 
quently this type of division has been termed regular. However, a study 
of the reduction phases showed, in rare cases, a little tardiness in pairing 
of univalent chromosomes, or occasionally a single chromosome lagging 
behind its associates in reaching the pole after either the first or the second 
reduction division but these irregularities were so rare that they may 
be disregarded. 
POLYPLOID RASPBERRIES 
The following section is a discussion of a smaller group of horticultural 
varieties of raspberries in which the chromosome number is larger than is 
the rule in diploid forms and in which chromosomes show characteristic 
irregularities in their distribution during meiosis. 
R. idaeus (?). Horticultural variety La France. This variety was secured from 
the introducer, John Scheepers Co., New York City. The original stock was intro¬ 
duced from France probably between 1890 and 1900 and grown at Stamford, Conn., 
from which place it was distributed. It resembles Merveille de Quatre Saisons Rouge 
very closely and may be identical with it. 
Horticultural variety Merveille Rouge. This old French variety was raised 
and introduced by Simon Louis Fr£res of Metz, France. Our stock which was 
secured from Laxton Bros.,.'Bedford, England, is very similar to Merveille de Quatre 
Saisons Rouge.
