    Flowers
    Male flowers red, ± 16 mm across, perianth flat, divided to within 2–3 mm of the base into 5 patent lobes, lobes ovate-triangular, 5–6 mm long, 3.5–4 mm wide, margin involute (distal three-quarters) membranous, straight, not undulate, concolorous, inconspicuous; outer and inner lobe surfaces densely white stellate-hairy; androphore cylindrical, 1.2–2 mm long, 0.5 mm wide; anthers uniseriate, ± 7, anther head 1 mm long, 2 mm wide, glabrous Female flowers and fruit unknown.
    Male
    Male flowers red, ± 16 mm across, perianth flat, divided to within 2–3 mm of the base into 5 patent lobes, lobes ovate-triangular, 5–6 mm long, 3.5–4 mm wide, margin involute (distal three-quarters) membranous, straight, not undulate, concolorous, inconspicuous; outer and inner lobe surfaces densely white stellate-hairy; androphore cylindrical, 1.2–2 mm long, 0.5 mm wide; anthers uniseriate, ± 7, anther head 1 mm long, 2 mm wide, glabrous
    Female
    Female flowers and fruit unknown.
    Ecology
    Evergreen forest with Milicia, Albizia and Dialium; ± 650 m
    Conservation
    The only known site for this species is an amphitheatre-like patch of forest 1–2 ha in extent that is fed by several streams that drain the Rondo Plateau above. About half a dozen trees were seen when the type collection was made. No immediate threats to this forest patch were noted, although some forest on the plateau above has been converted to plantation and forest degradation due to pit-sawing is a possibility (Bidgood and Vollesen pers. comm. 2005). Data on the forests of the Rondo Plateau can be found in Bidgood & Vollesen in K.B. 47: 759–764 (1992) and also in Vollesen in Davis et al. 1994, Centres of Plant Diversity 1: 225–226. WWF & IUCN. Cola rondoensis is here assessed on the basis of the data above, as critically endangered CR B2a, b (iii).
    Note
    Within the Cola stelechantha group (see notes under that species), C. rondoensis is most likely to be confused with C. quentinii (on limestone at Kimboza, T 6) and C. lukei (E Usambara Mts) since all three have short flower stalks.
