Loranthus rondensis Engl. [family LORANTHACEAE], in E.J. 40: 524 (1908); Sprague in F.T.A. 6(1): 327 (1910); F.D.O.-A. 2: 169 (1932) & T.T.C.L.: 289 (1949), excl. distr. E. Usambara
Tapinanthus rondensis (Engl.) Danser [family LORANTHACEAE], in Verh. K. Akad. Wet., sect. 2, 29(6): 118 (1933)
Information
Plant glabrous; branchlets angular, densely lenticellate. Leaves opposite or subopposite; petiole 5–10 mm. long; lamina coriaceous, oblong-lanceolate or ovate-oblong, 3–7 cm. long, 1.5–3.5 cm. wide, acute to obtuse at the apex, cuneate to rounded at the base, penninerved with 4–6 lateral nerves on each side. Umbels 2–4-flowered; peduncle 1–1.5 mm. long; pedicels 0.5 mm. long; bract cupular, with a short truncate limb, 1–2 mm. long. Receptacle 0.7 mm. long; calyx saucer-shaped, 0.5–0.7 mm. long, ciliolate. Corolla 2.5 cm. long or ?rather more, with yellow basal swelling, otherwise purplish red; apical swelling of bud slightly oblong-fusiform, slightly apiculate, 4.5 mm. long, 1.5 mm. in diameter; basal swelling 2–2.5 mm. long, 1.5 mm. in diameter, with tube narrowly constricted for 2 mm. above; lobes erect, 9–10 mm. long, upper half narrowly linear-oblanceolate, only slightly hardened inside. Filaments inserted a little above the base of the lobes, slender, decurved, slightly corrugated; anthers 3 mm. long; connective produced apically with a transversely elliptic appendage 0.4 mm. long and as wide as the anther. Style slender; stigma globose, 0.5 mm. across. Berry not seen.
Range
DISTR. T 8 known only from the type gathering
Distribution
TANZANIA Lindi District Rondo Plateau, 16 May 1903, Busse 2554!
Notes
A diminutive but distinctive species most closely related to several species in south-central and southern Africa. These are the species of Agelanthus most similar to Oncocalyx .
