    Type
    Type: Tanzania, Lindi District: Lake Lutamba, Schlieben 5433 (BM, holo.; BR, K!, iso.)
    Habit
    Evergreen shrub or tree 3–10 m tall.
    Bark
    Bark smooth with dark and pale grey patches; ultimate branchlets terete, 2–4 mm wide, whitish, glabrous, becoming longitudinally ridged; bud-scales caducous.
    Leaves
    Leaf-blade ovate to obovate, 2–17 cm long, 0.8–10 cm wide, apex obtuse to slightly acuminate, base subacute to rounded, rounded, rarely subcordate, 4–5(–6) pairs of main veins, veinlets highly reticulate, leathery, glabrous, dark green, drying grey green; petiole terete, 0.2–5.5(–10.5) cm long, 1–1.4 mm wide, glabrous; stipules caducous, narrowly triangular, ± 3 mm long, soon falling
    Inflorescences
    Inflorescences axillary, amongst the leaves or more usually below them on older wood, fasciculate with numerous single flowers in bud, but only 1–3 flowers open at one time.
    Bracts
    Bracts 3–6, ± elliptic, 1–2 mm long, entire or bilobed, sometimes amplexicaul, pubescent.
    Pedicel
    Pedicel 4–6 mm long, 0.3–0.7 mm wide, with short greyish stellate hairs; articulation basal, inconspicuous.
    Flowers
    Flowers cream or yellow, fragrant, perianth divided for 4/5 into 5(–6) ± ascending lobes, each (3–)3.5–4.5 mm long, 1.5–2(–2.5) mm wide, outer surface as flower stalk, inner minutely papillate Male flowers with androphore terete, 1.8–2.5 mm, glabrous; anthers uniseriate, 8–10, glabrous, in a disc 0.5–1 mm long, 1–1.8 mm diameter, ovary vestigial, concealed Female flowers with anthers barely reduced at the base of the ovary; ovary ± sessile, subglobose, ± 1 mm long, 1.5 mm diameter, densely tomentose; style ± 0.5 mm long; stigmas 4, recurved
    Male
    Male flowers with androphore terete, 1.8–2.5 mm, glabrous; anthers uniseriate, 8–10, glabrous, in a disc 0.5–1 mm long, 1–1.8 mm diameter, ovary vestigial, concealed
    Female
    Female flowers with anthers barely reduced at the base of the ovary; ovary ± sessile, subglobose, ± 1 mm long, 1.5 mm diameter, densely tomentose; style ± 0.5 mm long; stigmas 4, recurved
    Fruits
    Fruits red brown, borne in dense clusters, carpels one per fruit, ascending, longitudinally ellipsoid, 2–2.3 cm long, ± 1 cm wide, apex rounded, stipe 5 mm long, 3 mm wide; fruiting pedicel ± 4 mm long, glabrous
    Ecology
    Woodland or thicket near lakes or rivers, rarely in forest; 100–500 m
    Conservation
    Flora districts: Known to me from only seven fertile specimens. Threats to forest at some of its sites are documented in Clarke, Status Reports for 6 Coastal Forests in Lindi Region, Tanzania (1995). In view of these, an estimated area of occupancy of less than 2,000 km2, the species this is here assessed as VU 2Ba, b(iii), i.e.“vulnerable”, in view of its scarcity and restricted distribution.
    Note
    The original authors of Cola discoglypremnophylla drew attention to the close relationship with “ C. clavata” (i.e. C. pseudoclavata). They distinguished Cola discoglypremnophylla principally on the leaves being widely rounded and cordate or subcordate at the base, as seen in the holotype (see Brenan & Jones 1946, Fig. 1). However, the type specimen is aberrant, based on the fertile specimens that I have seen (Luke however disagrees) and this leaf shape is not typical of the species. Brenan was unaware of this aberration, rejecting a later collection by Eggeling of what appears to be this species, on the basis of leaf-shape. In fact, a normal specimen of C. discoglypremnophylla has leaves indistinguishable from C. pseudoclavata and the two can only reliably be distinguished in flower. The four principal discriminating characters are: Pedicel 0.4–0.6 mm diameter, perianth lobes 5, ascending, Pedicel 0.2–0.3 mm diameter, perianth lobes 6–8(–10), ± reflexed, Although no fertile collection has been seen by me from Mozambique (though Wild, loc. cit. refers to a specimen in bud and Luke (pers. comm. 2006) cites Luke & Kibure 10107 from the Mueda Plateau), it is very likely that a plant so widespread in the Lindi area should also occur over the border. Luke (pers. comm.) cites Luke, Luke et al. 7621 (EA n.v.), from Selous GR as firm evidence of the occurrence in T 6.
