Colubrina arborescens (Mill.) Sarg., Trees & Shrubs 2: 167. 1911; Ceanothus arborescens Mill.; Colubrina ferruginosa Brongn.

Trees or shrubs, 2—20 m, bark sometimes described as whitish and smooth, unarmed; young branches ferruginous-tomentose, bud scales not seen, bud scale remnants and/or scars at bases of branches not seen. Leaves alternate; blades (4.7) 8—21 x 3—9.2 cm, elliptic or lanceolate, membranaceous or subcoriaceous, adaxial surface drying  dull dark gray-green or dull red-brown (less frequently light red-green), abaxial surface drying light red-green (or less frequently light red-brown or light green), 4—8 pairs of lateral veins, adaxial surface ferruginous (tawny)-tomentose, rapidly glabrescent, abaxial surface dense to sparse ferruginous (tawny)-tomentose, glands, most easily observed on abaxial surface, dispersed on actual surface of blade (1) 2—7 on a side near margin and in a line more or less parallel to margin, the most proximal at 0.5—35 mm from the junction of blade and petiole, and (0) 1—8 at distal ends of intermediate veins or less frequently randomly dispersed, glands flat and circular or those most proximal elliptical with axis parallel to leaf margin, base usually truncate or truncate then slightly decurrent, less frequently cuneate or rounded, margin entire and without glands, apex acuminate, acute or obtuse, or most frequently acute and then short cuspidate; stipules rarely present, early caducous, 2.5—8 x 0.5—1.5 mm, narrow lanceolate-acuminate or linear; petiole (6) 10—23 (30) mm, glands at junction of petiole and blade absent. Inflorescence axillary compound and usually corymbose cyme, solitary in leaf axil or along leaf-less branch from axil forming a thyrse, ferruginous-tomentose; cymes 0.5—2.3 x (0.5) 1—2.5 cm, bracteoles caducous prior to anthesis, peduncle 1—10 mm. Flowers on pedicels 1—10 x 0.3—0.6 mm, in fruit (4) 5—12 x 0.4—0.75 mm; hypanthium 1—1.75 x (1.5) 2—2.5 mm. Sepals 1.3—2 (2.25) mm. At anthesis disc nearly filling the mouth of the hypanthium and totally hiding the inferior ovary, glabrous or ferruginous-tomentose centrally to covering entire disc. Mature fruit 6—9 mm, black, basal 1/4--½ concealed by hypanthium (1.5) 2--3.5 (4) mm, epicarp and mesocarp breaking regularly with and initially adhering to endocarp, later separating, columnella absent. Seeds 3—4 mm, broadly elliptic or obovoid, black (rarely dark chestnut-brown), seeds sometimes retained on receptacle after fruit breaks away, aril retained on seed or on receptacle.  

Possibly none of the collections made in Nicaragua from native populations, or possibly native in Chontales, cultivada en la zona pacífica; 500 m; fr sep; Neill 2489, Stevens 30438; Estados Unidos (sur de Florida), México (Veracruz and Yucatán Peninsula) a Panamá y en las Antillas.
