2 5. P. Cocomi’LL~4é Tenore. The Cocomilla Plum Tree. 
Identification. Tenore Prod, Suppl., 2. p.67.; Cat., 1819, p.46.; Dec. Prod , 2. p. 533.; Don’s Mill., 
2. p. 498. 
Spec. Char., §c. Flowers upon short peduncles, in pairs. Leaves obovate, 
crenulate, glabrous on both surfaces ; the crenatures glanded. Fruit ovate- 
oblong, with a small point, yellow, ? bitter or? acid. (Dec. Prod., ii. p. 533.) 
A shrub, a native of Calabria, in hedges, where it grows to the height of 
2 ft. or 3ft., and produces its white flowers in April. It was introduced in 
1824, The bark is febrifugal, and, in Calabria, is considered to be a spe- 
cific for the cure of the pestilential fevers common in that country. 
2 6, P. mari’tima Wangenheim. The sea-side-inhabiting Plum Tree. 
Identification. Wangenh. Amer., 103., according to Willd. Enum., p. 519.; Pursh Fl. Amer. Sept., 
1. p. 332.; Dec. Prod., 2. p. 533. ; Don’s Mill., 2. p, 499. 
Spec. Char., §c. leaves lanceolate-ovate, serrate. Flowers in pairs. Fruit 
small, round, sweet, dark blue. (Dec. Prod., ii. p. 533.) A shrub, a native 
of North America, in sandy soils, on the sea coast, from New Jersey to 
Carolina, where it grows to the height of 6 ft. or 8ft. Introduced in 1818, 
and producing its white flowers in April and May. In its native country, 
these are succeeded by fruit, of the size of a pigeon’s egg, dark purple, and, 
according to Pursh, very good to eat. There are plants in some of the 
principal European nurseries; but we are not aware of any of them having 
yet ripened fruit. P.acuminata Michx. (Fl. Bor. Amer., p. 284.) is thought 
by Pursh to be identical with this species. 
x 7, P. pUBE’sCENS Poir. The pubescent-/eaved Plum Tree. 
Identification. Poir. Suppl., 4. p. 584., not of Pursh ; Dec. Prod., 2. p.533.; Don’s Mill., 2. p. 499. 
Spec. Char., §c. Leaves with short pubescent petioles, and disks that are 
slightly pubescent, ovate, thickish, rounded, or shortly acuminate and un- 
equally toothed. Flowers mostly solitary and nearly sessile. Fruit oval. 
(Dec. Prod., ii. p. 533.) A shrub, growing to the height of 2 ft. or 3 ft., and 
producing its white flowers in May. It has been in cultivation in Britain 
since 1818; but its native country is unknown. 
2 8. ? P.ptvarica‘ta Led. The divaricate (? -branched) Plum Tree. 
Identification. Ledeb. Ind. Hort. Dorp., Suppl. 1824, p.6.; Dec. Prod., 2. p. 534.; Don’s Mill, 2. p. 504. 
Spec. Char., §c. Branches spineless. Leaves with glandless petioles, and 
disks oblong-elliptical, tapered to both ends, concave aboye, serrate, gla- 
brous, with the midrib bearded beneath. Flowers solitary, very numerous. 
Calyx reflexed. Fruit elliptical, yellow. (Dec. Prod., ii. p. 534.) A shrub, 
growing to the height of 8ft. or 10ft. on Caucasus, and producing its 
numerous white flowers in April. It has been in cultivation in Britain 
since 1820; but it is not common in‘*collections. 
App. 1. Other Species of Prunus. 
P. microcdrpa Meyer (Virg, Pfl., p. 166. ; Don’s Miil., 2. p. 504.) is described as an unarmed shrub, 
with leaves glabrous, conduplicate, ovate-elliptic, sharply serrated, and with flowers in umbels; the 
drupe and the nut oblong. It is a native of Caucasus, on Mount Bechvarmak ; but has not yet been 
introduced into Britain. 
P. tomentosa Thunb. (Fv. Jap., 303., and Don’s Miil., 2. p. 498.) has the branches unarmed, and the 
peduncles solitary. The leaves are ovate and serrated, villous above, and, as well as the petioles, to- 
mentose beneath. The flowers are white, and the drupe the size of a pea. A shrub, from 6 ft. to 8 ft. 
in height, a native of Japan, not yet introduced. 
P. chinénsis Blum, (Bigel., p. 1104. ; Don’s Miill., 2. p. 504.) Leaves oblong, acuminated; furnished 
with two glands at the base, and unequally serrulated. Flowers in umbellate fascicles, Fruit round, 
and of a yellowish red. A tree, a native of China, not yet introduced. 
Other Species. The genus Prunus L. formerly included one or two species now united with Ar- 
meniaca Tourn.,, and anumber which have been separated from it, and formed into the genus Cérasus 
Juss. In consequence of this, there appears to us considerable confusion among the species of these 
three genera; and we think it likely, that, when the fruit of all the sorts has been seen, some of them 
will be restored to Prinus. Among these, we think, will be Cérasus nigra Lozs., which, in the flowers, 
leaves, colour of the wood, and general habit of the plant, asshown in the plants bearing this name in 
the Hammersmith Nursery, has every appearance of being a variety of the common plum; orof that 
form of it known as Prinus maritima, which, with some others enumerated above, we cannot bring
