‘‘Fort Belknap,’ now known as Belknap, is on the Brazos River, 
in Young County, northern Texas. Another variety, material of 
which has not been seen but which is referred to this group by 
Waugh (76, p. 181), is reported to have been found by Dan Irby, of 
Texas, ‘‘growing on the grounds of an old Indian settlement in his 
vicinity.’ Crimson Beauty, likewise reported to be of Texas origin, 
probably came from cultivated material. The introducer, A. L. 
Bruce, writes that it came from trees in Grayson County, growing in 
ground ‘‘being used as a home garden.’ The variety Captain was 
introduced about 1892 by A. M. Ramsey & Son, of Austin, Tex., under 
the name Columbia. Mr. Ramsey obtained it from J. M. Shell, of 
Georgetown, Tex., and Mr. Shell writes that he in turn received the 
variety from Mr. Berckmans, of Augusta, Ga., as Cumberland, and 
sold it as such. It is evident that the name Columbia originated by 
an error either in writing or reading the label intended for Cumber- 
land. Later the name Columbia was changed to Captain to avoid 
confusion with a domestica variety. While perhaps it may be difficult 
to furnish definite proof, it is nevertheless extremely probable that 
these varieties were all originally carried to Texas from the region of 
the known natural range of the species, either by the Indians or by 
the early settlers. . 
Prunus HortuLtana Hysrrps. 
Among the cultivated varieties are a few supposed to represent 
hybrids of Prunus hortulana with P. triflora, P. americana, P. mun- 
soniana, and P. hortulana mineri. 
Prunus HortuLana MINERI Bailey. 
Prunus hortulana mineri Bailey, 1892, N. Y. Cornell Agr. Exp. Sta. Bul. 38, 
p. 23. 
A form differing in botanical characters but little from the species. 
The bark of the trunk in mature trees shows a slight approach to the 
scaly character of that of Prunus americana. The branches are per- 
haps somewhat more rigid than in the species and the foliage is a 
darker green. This form blooms a few days earlier and the fruit also 
ripens earlier. It is, however, impossible to distinguish minert from 
the species in saya material. 
The ‘‘Miner group” is a group well recognized by pomologists, but 
careful study both in the herbarium and in the field fails to reveal 
any distinctive characters other than as indicated above. It is 
usually contrasted by pomologists with the ‘‘Wild Goose group,” 
Prunus munsomana, or with P. americana, but not with the ‘‘Way- 
land group,” P. hortulana, to which it is clearly most closely related. 
The varieties referred to this form have mostly originated under cul- 
tivation and would therefore not be expected to show the intergrada- 
tion with the species that is found in a number of specimens from a
