characters, this variety retains more of the Prunus iexana characters than any other 
hybrid noted. But one plant discovered, south of Big Sandy Creek, Llano County, 
Tex. 
Prunus texana hybrid. 
Hort. var. Sumlin. 
An erect, slender-branched shrub, with grayish brown bark on old wood and slender, 
yellowish brown pubescent twigs of young growth. 
Leaves ovate elliptic, acute at apex, rounded or broadly wedge-shaped at base, 
serrate with glandular teeth; the upper surface dull green, with short scattered hairs; 
lower surface grayish green; hairy tomentose; 4 to 5 cm. long; midrib rather conspicu¬ 
ous; petiole short; stipules 3 to 4 mm. long, narrow, acute, glandular toothed. 
Fruit a small, roundish, pubescent-coated plum, upon a stalk 4 to 10 mm. long. 
Not seen mature, but described as red in color and a desirable fruit, ripening somewhat 
later than the Prunus texana parent. Some of the characters in this variety suggest 
that the cross may have been derived from a local wild plum usually classed as P. 
americana var. lanata Sudworth, though perhaps an undescribed species. Trees of 
this form occur in the same field and, while flowering a little later, overlap P, texana 
in blooming period. 
Prunus texana hybrid. 
Hort. var. Holmann. 
An erect-growing shrub 1 to 2 meters high, of irregular branching habit, inclined to 
be spiny. Young growth slender, yellowish brown, with thin pubescence; older wood 
iron gray. 
Leaves 3 to 5 cm. long, 1.5 to 2 cm. broad, ovate lanceolate, with rounded base and 
acute apex; margin finely glandular serrate; upper surface with scattered short hairs; 
lower thinly pubescent; petiole 4 to 6 mm. long. 
Fruit a small oval plum with a thinly pubescent surface, borne singly or in pairs; 
stalk 6 to 10 mm. long; calyx sometimes persistent. Described as being of poor 
quality. Found in a scattering group of small thickets, indicating that it has ability 
to spread by root sprouts. 
Prunus texana hybrid. 
Hort. var. Gephart. 
A tree 2.5 meters high, with numerous slender semipendulous branches; young 
growth reddish brown, finely pubescent; older wood silvery gray or iron gray. 
Leaves narrowly elliptical, approaching oblong; apex rounded or acute, finely 
doubly serrate with minute glandular teeth; base rounded or broadly wedge shaped; 
upper surface dull green, covered with scattering short hairs; lower surface ashy gray 
green, finely reticulated, silvery pubescent; 3 to 4 cm. long; stipules 2 to 3 mm. long, 
slender, acute, glandular toothed. 
Fruit borne in great profusion, smooth, plumlike in appearance, oval, 2.5 cm. long, 
dull yellow, with slight pubescence; stalk 3 to 5 mm. long; a juicy fruit, the rather soft 
flesh clinging to the pilose pit much as in the original species, somewhat subacid and 
lacking in quality. The earliest ripening of any of the Prunus texana hybrids so far 
noted (May 13 to 18). 
Prunus texana hybrid. 
Hort. var. Johnson. 
This variety was found growing interlocked with the Gephart, but is more upright 
and stiff branched in habit and quite distinct. Young twigs reddish brown, slightly 
angled at the nodes, sparingly pubescent; older growth grayish brown or iron gray.
