Leptocereus

A Cuban species with a tree habit and densely spiny fruits. Germination at different temperatures was studied in a population from the Yaguanabo River mouth. Warmth suitable for adult plants did not translate into high seed germination in the hottest experimental treatments.

A western Cuban Leptocereus with climbing or trailing stems. Its present circumscription includes several names used in earlier publications. Seed data remain assigned to separate populations because their responses to temperature differed markedly.

A species of the eastern Dominican Republic that grows near the sea on coral limestone. It may form small trees in woodland, while retaining a shrubby habit in more exposed places. Its flowers and fruits bear very weak spines.

A species of the Cuban limestone hills of the Sierra del Chorrillo. Seeds in the studied material germinated more successfully in the warmer treatment than those of most other leptocerei compared. The finding concerns an early life stage and one population.

A species of steep coastal rocks on the Samaná Peninsula. It inhabits a region with high rainfall, while its local habitat consists of exposed cliffs. Stems may produce small, readily detachable branches, whose role in population recruitment must be distinguished from observations of their structure.

A species of the southwestern Dominican Republic with long grey-green stems that often lean on surrounding vegetation. Usually 6 ribs and the plum-red colour of fully ripe fruits described in the 2023 revision are useful distinguishing features.

A pink-flowered Cuban leptocereus described in 2025. In the accessible abstract, the diagnosis highlights outer stamens with aborted anthers and brown fruits. The profile retains the scope of the available description.

A species of Culebra Island in Puerto Rico. DNA studies place it together with Leptocereus quadricostatus in an Antillean lineage close to Leptocereus paniculatus. This card develops the documented range and relationships, the aspects best supported in the supplied papers.

A Cuban species of the seasonally dry forest of the Sierra de Anafe, with pink flowers that open in the evening. A study published in 2026 demonstrated self-incompatibility and effective nocturnal pollination. The only pollinator recorded was the bat Monophyllus redmani.

A Cuban tree cactus formerly described in the genus Dendrocereus. Its large nocturnal flowers and smooth fruits stand out among leptocerei. DNA studies distinguish it from the similar Leptocereus undulosus of Hispaniola.

A tree species of the dry lowlands of Hispaniola that forms large stands. Its short flowering shoots carry densely packed areoles and become woody with age. The difference between a slender seedling and a heavily branched adult tree is important for identification.

A species of Puerto Rico and the Virgin Islands with undulate rib margins and spiny floral structures. DNA analyses link it to Leptocereus grantianus. Stem resemblance to other leptocerei is assessed together with provenance and reproductive characters.

A slender-stemmed species described in 2023 from near Azua. Long glossy segments thread through the branches of dry woodland. The revision linked it to some historical collections identified as Leptocereus weingartianus.

A Cuban species of limestone hills whose reproduction and seasonal growth were studied in detail at Pan de Matanzas. Nocturnal flowers vary in colour, and seeds respond to light and temperature conditions. Long-term observations describe both stem growth and dieback.

A species of the northern coast of Hispaniola with golden young spines and undulate ribs. It may form shrubs or large trees. The 2023 revision recognised it in two separated areas of Haiti and the Dominican Republic.

A Cuban species accepted in the atlas together with the historical names Leptocereus maxonii and Leptocereus santamarinae. Studies using those names revealed differences among populations in morphology and germination. Their results remain separated according to material provenance.

A tree cactus of Hispaniola with nearly spineless terminal segments and long nocturnal flowers. Its large, smooth fruits contain seeds embedded in mucilaginous pulp. Field surveys encountered adult trees much more often than young plants.

A small tree or shrub of the Sierra de Bahoruco. Glossy green segments and strongly undulate rib margins help distinguish it from other Hispaniolan leptocerei. The species was described in 2021, and its field range was expanded in the 2023 revision.

A species with long slender stems that climb through vegetation or hang down. The 2023 revision separates it from several Hispaniolan plants formerly included under the same name. Identification requires attention to provenance, stem surface, ribs and fruits.

A Cuban leptocereus placed in the pink-flowered group. Seeds from the coastal Boca de Jaruco population showed a strong reduction in germination in the warmer treatment. Some seeds that remained viable recovered germination when the temperature was lowered.
