Names
PAVETTA transjubensis Chiov. [family RUBIACEAE], (1932);. type: S3, Mansur, Guidotti 222 (MOD holo.).
Information
Evergreen shrub, c. 3 m tall; young stems glabrous. Leaf blades elliptic, somewhat lanceolate or narrowly obovate, 6–14.5´2.7–5.8 cm, acute to acuminate and mostly ending in a very fine point at apex, glabrous, papery or stiffly papery; lateral nerves in c. 6 main pairs; bacterial nodules dot-like, scattered, conspicuous on young leaves, less so on mature leaves; petiole 0.7–2.4 cm long; stipule limbs 3–4 mm long, truncate or triangular, with 1–2 mm long tip, papery in texture usually turning brown. Inflorescences corymbose, relatively lax, up to 3 cm across (excl. corollas); primary inflorescence branches 5–7 mm long, glabrous; secondary branches present or absent; pedicels 5–10 mm long, glabrous. Calyx glabrous; limb-tube c. 1 mm long; lobes 2–4 mm long, narrowly triangular, acute, glabrous or sparsely ciliate. Corolla-tube (12–)17–18 mm long, glabrous outside; lobes (6–)7–8 mm long, apiculate-acuminate. Fruit c. 8 mm in diam.

Notes
Previously, because the type (or any other) specimen had not been seen, this species was considered conspecific with the Kenyan P. s phaerobotrys K. Schum. subsp. tanaica (Bremek.) Bridson (Fl. Trop. E. Afr.: 649, 1988). However, it differs in the following respects: stipules papery (not membranous and transparent as in subsp. tanaica), inflorescence corymbose (not compact and hemispherical), calyx-lobes narrowly triangular widest at very base (not strap-like or narrowly lanceolate, widest above base), and corolla-tube (12–)17–18 (not up to 9) mm long.
