Description
Trees up to 10.0 m tall or smaller shrubs 2.0-5.0 m tall, crown arching, galls absent; indument glabrescent, young twigs variously pilose through glabrescent; bark grey light to grey brown, longitudinally fissured, wood light; thorns 0.80-1.0 cm long, robust, somewhat acute, sometimes slightly curved at tips, simple, scattered, alternate, glabrous. Leaves fasciculate, occasionally stipulate (2 deciduous stipules, as stated by Lasser 758: US!), dark green, dark pale, sometimes red when older; petiole 0.2-1.5 cm long, slender, hirsute, rarely glabrous; blade 0.9-10.8 cm long, 0.3-4.5 cm wide, obovate, widely obovate, rarely elliptic, coriaceous, primary veins prominent, secondary veins 5-6, tertiary veins reticulate; base cuneate or sometimes rounded, rarely oblique; apex retuse, rounded, obcordate, emarginate, acute, occasionally mucronulate; adaxial surface glabrous or with scattered trichomes (especially on the midrib and at tips), rugose, with cystotliths, abaxial surface glabrous or with stiff trichomes on the midrib and tips. Inflorescence terminal or axillary, secondarily branched, branches slender, glabrescent, pedicels 0.30-0.40 long. Calyx 0.18-0.25 cm long, coriaceous, hirsute outside, glabrous inside, lobes 0.15-0.18 cm long, 0.10-0.20 cm wide, divided from the base, triangulate, apex slightly acute, margin strigose. Corolla 0.35-0.40 cm long, white, yellowish, orange, rarely green (Ferrari 706: F!), tube funnel-shaped, 0.18-0.20 cm long, lobes 0.20-0.25 cm long, ovate, glabrous on both sides, slightly ciliate at tips. Anthers of male flower 0.15-0.30 cm long, filaments 0.20-0.23 cm long, adnate to the corolla tube for 0.10-0.12 cm, pollen present; anthers of female flower 0.08-0.10 cm long, filaments 0.06-0.10 cm long, adnate to the corolla tube for 0.02-0.03 cm, pollen absent. Ovary of male flower subglobose, stylodia 2, branches 0.07-0.10 cm long, glabrous, with strigose, grey trichomes at tips; ovary of female flower globose, 0.12-0.14 cm long, stylodia 2, 0.18-0.22 cm long, slightly unequal, 2 well developed stigmas, cotyliform. Fruit 0.50-0.80 cm tall, 0.60-0.80 cm wide, globose, green when immature, yellowish reddish through red and dark purple during maturation; style accrescent, not persistent; pyrene 0.40-0.60 cm tall, 0.30-0.40 cm wide, 0.15-0.30 cm deep, with various ridges on the abaxial surface.

Taxon discussion
Rochefortia spinosa
is among the species with the largest leaf size after
R. lundellii.
Specimens across different geographical areas are relatively homogenous displaying a low variability of morphological traits (e.g., few collections have leave lengths shorter than 5.5 cm). The species is not sympatric with any other species but morphologically, it resembles
R. lundellii
. It can be distinguished from the latter by the presence of 2 stylodia and generally by the less extensive developed thorns on stems. In the past,
R. spinosa
was one of the most confusing
Rochefortia
species and was believed being distributed across multiple islands of the Caribbean. However, molecular data (
Irimia et al. 2015
) indicate that the species is restricted to northern South America (primarily Colombia and Venezuela, but also Peru though with few collections available).

Common names
"macarao"
, "pega paloma" and
"tachuelo"
in Venezuela and "cruceto macho" and "tatacun o revienta puerco" in Colombia.
Economic uses
In Venezuela, the species is occasionally cultivated and forms hedgerows together with
guamacho
(probably
Pereskia guamacho
F.A.C.Weber:
Cactaceae
, as noted on Ferrari & Bunting 713: F!).
