Tree ca. 5 m tall; young twigs and petioles glabrous. Leaves: petioles 5-8 by 1.5-2 mm; lamina narrowly elliptic, 11-20 by 4-5.5 cm (index 3.7-4), chartaceous, dark/olive brown, shiny above, lighter pinkish-brown, matt below, glabrous above and below, base acute to cuneate, apex acuminate (acumen 7-10 mm long), primary vein ca. 1 mm wide at widest point, verrucose below, secondary veins 8-10, no intersecondary veins, distance between from 5 mm at the base to 30 mm closer to the apex, angles with primary vein from ca. 60° at the base to 60-70° closer to the apex, forming distinct loops, smallest distance between loops and margin 2.5-3.5 mm, tertiary veins reticulate. Inflorescence of single flowers, solitary or clustered in groups of at least two, on brachyblasts on the main trunk; peduncles, 2-3 by 1-1.5 mm (in fruit); pedicels 38-42 by 1 mm at the base, 1 mm at the apex (in fruit), peduncles and pedicels glabrous; lower bract(s) not observed; upper bract attached within basal half of pedicel, ovate, ca. 1 by 0.7 mm, obtuse, glabrous; flowers not observed. Monocarps 10-13, ellipsoid, strongly asymmetrical (stipes inserted within basal half of longest axis), 13-14 by 10-11 mm, with an excentric, to 0.2 mm long, apicule, green maturing through red to dark blue in vivo, dark brown in sicco; stipes 15-18 by ca. 1 mm increasing to 1.5 diam. when mature; fruiting receptacle depressed ovoid, 4-5 mm diam.; monocarps, stipes and receptacle glabrous. Seeds ellipsoid, orange-brown, pitted, 9-11 by 6-8 mm, raphe sunken, regular.

The strongly asymmetric monocarps of Cremastosperma chococola resemble those of C. antioquense : see above for distinctions.
Preliminary conservation status.
Only three collections of C. chococola are known to us, from different localities but within a restricted region and only one of which is in a protected area. Endangered [EN] (Table 1 View Table 1 ).
