Opuntia leucotricha DC.

A true species with white flowers.  [JD].  ‘Often 3 to 5 meters high, with a large top; trunk as well as the older joints covered with long white bristles; joints oblong to orbicular, 1 to 2 cm. long, pubescent; areoles closely set, the upper part filled with yellow glochids, the lower part at first with only I to 3 weak white spines; flowers, including ovary, 4 to 5 cm. long; petals yellow, broad; ovary with numerous areoles, the upper ones bearing long, bristly glochids (1 cm. long); style red; stigma-lobes green; fruit variable, 4 to 6 cm. long, white or red, the rind not easily coming off from the pulp, aromatic, edible.’  [Britton & Rose – The Cactaceae vol.I, p. 174/1919].

Horticultural & Botanical History

The classification and synonymy of this plant is in some doubt.  ‘Opuntia leucacantha Link and Otto (Salm-Dyck, Hort. Dyck. 362. I834), published first in 1834 - although the name occurs in literature as early as 1830 (Verh. Ver. Beford. Gartenb. 6: 434. I830) - which was later taken up as Consolea leucacantha by Lemaire (Rev. Hort. 1862: 174. 1862), seems to belong here rather than to O. spinosissima.  If it came from Mexico, as reported, it could not be O. spinosissima or any of its relatives, for none of them is known from Mexico.

Opuntia subferox Schott (Pfeiffer, Enum. Cact. 167. 1837) was given as a synonym of this species, while O. leucacantha laevior Salm-Dyck (Cact. Hort. Dyck. 1844. 47. 1845) and O. leucacantha subferox Salm-Dyck (Forster, Handb. Cact. 497. 1846) were supposed to be based on O. subferox.

Opuntia leucantha (De Candolle, Prodr. 3: 474. 1828), unpublished, is doubtless the same as O. leucacantha.’ [Britton & Rose – The Cactaceae vol.I, p. 174/1919].

Introduced to Britain in 1825.  [JD].
