6b. Monotes duvigneaudii Meerts var. concolor Meerts View in CoL , var. nov.

Type: — D.R. CONGO. Katanga: Upemba, Kibara, éboulis près de la rivière Manda , le long des chutes, alt. 1400 m, 13 April 1949, de Witte 06092 (holo-: BR!; iso-: BR!) .

Diagnosis:— Differs from the type variety by the concolorous leaves with a glabrous lower surface or with the indumentum not covering the reticulum.

Illustrations: — Figs. 3J View FIGURE 3 , 4I View FIGURE 4 .

Distribution in D.R. Congo: — Katanga, apparently rare ( Fig. 16A View FIGURE 16 ). Endemic of D.R. Congo.

Habitat and ecology: —Shrub savannah or herbaceous savannah.

Additional specimens examined:—D.R. CONGO. Katanga: Kazia , savane herbacée, 25 June 1953, Desenfans 3509 ( BRLU!) ; Kazia , savane arbustive, 25 June 1953, Desenfans 3584 ( BRLU!) .

Discussion:— This variety is superficially similar to Marquesia acuminata and Monotes doryphorus . Its relationship with the latter needs further investigation.

The type specimen of this variety is the sole collection of M. duvigneaudii with fruits. Its fruits are young, the wings are 1.5–2.0 × 0.8–1.0 cm with a reddish tinge, and the fruit is ovoid with a conical apex.
