= Monotes sp. 1 ( White 1962: 263).

Diagnosis: — Differs from the type variety by the following traits: indumentum of the leaf upper surface comprising long straight simple hairs and a dense, persistent, cover of much shorter, stellate hairs with 4–12 spreading branches ca. 100 μm long, arising from a bulbous base.

Shrub with flattish spreading crown. Leaf blade large, with at least a few exceeding 18 × 10 cm, lower surface always with a very thick fulvous tomentum of woolly hairs, completely hiding the areoles and reticulum. Fruit: wings often larger than in the type, 2.0–5.0 cm long, attenuate at base.

Illustrations: — Figs 3F View FIGURE 3 , 4F View FIGURE 4 , 5K View FIGURE 5 , 9A View FIGURE 9 .

Distribution in D.R. Congo: —D.R. Congo: Upper Katanga and Lower Katanga ( Fig. 16F View FIGURE 16 ).

Distribution elsewhere: —NW Zambia (new record for that country); restricted distribution.
