Source-derived summary

Leuenbergeria guamacho, the guamacho, is a species of plant that belongs to the cactus family and is one of the few cacti with spines that bears a strong resemblance to deciduous trees.

Description

The tree is slow-growing, up to 8 m (26 ft) tall, with a brown trunk, a rounded crown up to 3 m (9.8 ft) in diameter, with simple alternate leaves. Its flowers are bright yellow. The fruit is edible, round, and yellow-green when ripe, filled with numerous black seeds.

Range

Originating in the American tropics from Mexico to northern South America, it can be found in great numbers in the mountains near the Venezuelan coast. It is found in drier regions and most notably in the national parks of Venezuela.

Taxonomy

Leuenbergeria guamacho was first described as Pereskia guamacho by Frédéric Albert Constantin Weber and first recorded in the Dictionnaire d'Horticulture 2: 938–939. 1898. It has also been formerly classified as Rodocactus guamacho, Pereskia colombiana, Rhodocactus colombianus, and Rhodocactus guamacho.

Editorial summary

Begin with the source’s own compact description: “Leuenbergeria guamacho” is species of cactus in Central America. The dossier treats that line as a proposition to test through Leuenbergeria, guamacho and species, not as a finished interpretation.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1898, 2002—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Leuenbergeria, guamacho and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of cactus in Central America” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Mar 20, 2026. The linked authority identifier is Q92390575. The first chronological checks are 1898 and 2002.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
