Thulin (Clerodendrum, Premna, Rotheca, Vitex) [updated by M. Thulin 2008]
Names
PREMNA senensis Klotzsch [family LABIATAE], (1861).
Information
Shrub or small tree, 1–5 m tall; young branches brownish or whitish, first pubescent but soon glabrous. Leaf-blades ± broadly ovate, 1.5–8.5 x 1–1.5 cm, acuminate to subacute at the apex, truncate to shortly cuneate at the base, with coarsely crenate or dentate to entire margins, sparsely to densely pubescent or subglabrous on both sides and with very obscure glands, tertiary venation forming a ± distinct reticulum; petiole 5–20 mm long, pubescent. Inflorescences 1–3(–5) cm long, mostly on short lateral shoots; peduncle 0–1(–3) cm long; pedicels 0.5–3 mm long; bracts 2–4 mm long. Calyx glandular; tube c. 1.5–2 mm long; lobes 0.5–1.5 mm long. Corolla white; tube 2.5–3.5 mm long, densely hairy at throat; lobes 2.5–3 mm long, glabrous to sparsely hairy outside. Fruit black when ripe, 3.5–6 mm in diam.
Range
C1; S2 E Kenya, Tanzania, Burundi, Zaire and southwards to Botswana.
Altitude range
100–220 m.
Distribution
SOMALIA Thulin & Abdi Dahir 6733; Thulin, Hedrén & Abdi Dahir 7378.
Notes
The record of P. senensis from Somalia in Cuf. Enum.: 796 (1962) was based on Gorini 229 (FT) from S3, which is not this species but possibly P. velutina Gürke. Better material is needed.
