An elliptic solid.
Lacking hairs smooth. glabrescent Becoming hairless.
Bearing glands.
Plant originating from the cross-fertilisation of genetically distinct individuals (e.g. two species or two subspecies).
midveinCentral and principal vein in a leaf.
(subsp.) Taxonomic rank for a group of organisms showing the principal characters of a species but with significant definable morphological differentiation. A subspecies occurs in populations that can occupy a distinct geographical range or habitat.

A deciduous tree up to 15 or 20 ft high, or (under wild conditions) a shrub, of suckering habit, with brown, usually glabrous or almost so, unarmed branches. Leaves elliptical or obovate, downy beneath on the midrib and veins, 112 to 3 in. long, of a dull greyish green, margins set with rounded even teeth; stalk usually downy, glandular, about 12 in. long. Flowers produced in April singly or in pairs, from the buds of the previous year’s shoots, white, 34 to 1 in. across; stalks 14 in. long, glabrous. Fruits variable in shape, size, and colour. Stones flattened, sharp-angled, slightly pitted, usually free from the flesh.

For the origin of the plums and related fruits see below. It is occasionally met with in hedgerows, etc., as an escape from cultivation or semi-naturalised, but is not so common as the bullace, from which it is well distinguished by its unarmed branches and more or less glabrous twigs.

The plum is largely used as a stock for almonds, peaches, etc., being very hardy. It is not worth growing for ornament in gardens, at least in its typical form. An old tree in blossom is pretty, but not more so than the fruit-bearing plums commonly grown, of which it is one of the parents. The double-flowered ‘Plantierensis’ is sometimes grown as an ornamental.

subsp. insititia (L.) Poir. P. insititia L. Bullace. – Twigs downy and remaining so for a year or so; branches often thorny, brown. Leaves as in typical P. domestica. Fruits usually rounded or broadly ellipsoid, usually dark purple in naturalised trees. Stone not so flattened as in the plum, with blunt edges and clinging to the flesh.

The bullace is not a native of Britain but has become thoroughly naturalised. It is now little cultivated, but three orchard varieties are described in the latest supplement to the Dictionary of Gardening. The Mirabelle group of plums, with round, yellow fruits, belong to this subspecies. The damsons, too, are said to derive from it. They take their name from Damascus, where they have been cultivated since before the Christian era.

The Green Gage or Reine Claude is by some authorities given the rank of subspecies – subsp. italica (Borkh.) Hegi; by others it is placed under subsp. insititia.

Modern research has shown that that P. domestica and its subspecies are hexaploid and of hybrid origin. The sloe, P. spinosa, is a tetraploid species and the cherry plum, P. cerasifera or P. divaricata diploid. In the Caucasus hybrids between them, which are triploid and sterile, are said to occur quite frequently. But doubling of the chromosome number gives rise to fertile, more or less true-breeding hexaploids and it is from these that the plums and their allies are derived (Crane and Lawrence, The Genetics of Garden Plants, ed. 4, pp. 237–8; Rybin, Planta, Vol. 25, pp. 22–58).
