DESCRIPTIONS OF HYBRIDS 
Prunus hortulana (Wild Goose) X texana, 
Hort. var. Ramsey. 
A rather ragged branched tree about 2 meters high, with yellowish brown pubescent 
twigs of new growth. Leaves ovate lanceolate, acuminate at apex, rounded or broadly 
cuneate at base, serrate or doubly crenulate serrate, with short glandular teeth; upper 
surface dull with scattered short hairs; lower surface grayish green, silvery tomentu- 
lose; petiole stouter than in most of the hybrids, 5 mm. to 10 mm. long, tomentose; 
stipules narrow, acute, glandular toothed. 
The flowers, which appear before the leaves, about the middle of March, are white, 
about 8 mm. broad, borne in three or four flowered umbels on slender, pubescent 
pedicels. The calyx is pubescent, lobes pubescent on both surfaces, margins 
glandular. 
The fruit, ripe about June 15, is globose, 2 to 2.5 cm. long, the rather thick dull-red 
skin sparingly tomentulose, the thin reddish flesh clinging to the velvety coated pit, 
which is turgid, oval, pointed at either end, and with a broad ventral ridge; the pedicels 
are 8 to 10 mm. long and stouter than in most of the hybrids of the species. This fruit 
is acid, rather austere, but of value in making jellies, marmalades, etc. The origina¬ 
tor, Mr. Ramsey, states that it is a remarkably regular bearer. It seems to thrive well 
on a strongly calcareous soil and has been grown to a good size worked on peach stock. 
Primus texana hybrid. 
Hort. var. Llano. 
A low, ragged bush, 1 to 1.5 meters high, as it occurs in thickets in the stony pastures 
in Llano County, where it was first observed more than 30 years ago and where it 
spreads slowly by means of root sprouts. Worked on peach stock the twigs of young 
growth become long, slender, and pendulous with little disposition to spiny branches. 
The twigs of young growth are reddish brown, thinly pubescent. 
Leaves elliptical or ovate elliptical, apex acute or narrowed and shortly acuminate, 
base rounded or broadly cuneate; margin serrate or doubly serrate; the teeth glandu¬ 
lar tipped; the upper surface dull green, with scattering short silvery hairs; russety 
green with thin pubescence beneath; 3.5 to 4 cm. long, 1.5 to 2 cm. broad; the midribs 
yellowish brown; slender petioles about 7 mm. long; stipules 3 to 5 mm. long, narrow, 
acute, coarsely glandular toothed. The flowers appearing with the leaves are white, 
5 to 8 mm, broad; calyx tube campanulate, pubescent; lobes short, broadly ovate, with 
glandular teeth and hairy inner surface; petals obovate with short claw. 
The fruit, ripening in June, is globose, a little compressed, 2 cm. in diameter; color 
dull red; skin rather thick, coated with a thin, fine pubescence; flesh netted, clinging 
to the pit, which is turgid; oval, obtuse at base and apex, coated with velvet pile; 
pedicel short. This fruit, produced in great abundance, is of a sharply acid flavor, 
but is highly esteemed for domestic use. 
Prunus texana hybrid. 
Hort. var. Willow. 
A willowy shrub, 1 meter high, profusely branched, the branches angled at nodes, 
long, slender, tapering; young growth greenish brown, pubescent, but becoming 
smooth iron gray with age. 
Leaves ovate lanceolate; apex acute; base rounded; margin finely and evenly 
glandular serrate; upper surface dull green with scattered hairs; under surface grayish 
green with a thin silvery pubescence; 3 to 4 cm, long, 1.5 to 1.7 cm. wide; venation 
prominent; petioles 4 to 5 mm. long; pubescent; fruit solitary as far as seen, a small 
roundish plum with the surface covered with scattering hairs; stalk 3 to 4 mm. long; 
not seen in mature condition. While an evident hybrid with distinct plumlike
