Hermannia glanduligera K.Schum. [family STERCULIACEAE], in Verh. Bot. Ver. Prov. Brandenb. 30: 232 (1880) & in E.M. 5: 57 (1900); Wild in F.Z. 1: 545 (1961); Wild & Gonç. in Fl. Mocamb. 27: 31 (1979). Type: Namibia “Olukonda, (Ondongo-Stamm) Amboland” (not located, B †?)
Hermannia teitensis Engl. [family STERCULIACEAE], in E.J. 55: 370 (1919). Type: Kenya, Teita District: Ndara, Hildebrandt 2385 (B, holo., presumed destroyed, K! iso.)
Hermannia viscosa [family STERCULIACEAE], sensu Agnew, U.K.W.F. ed. 2: 96 (1994), non Hiern
Information
Annual herb to short-lived perennial 15–100(–200) cm tall, usually viscid, stem 3–7.5 mm diameter at base, generally with 4–5 subequal ascending and prostrate branches from near the base; branches invested densely with predominantly simple, glandular hairs, sometimes mixed with simple crinkled hairs and with sporadic stellate hairs, less usually almost entirely stellate-hairy. Leaf-blade linear-lanceolate, lanceolate, or linear-oblong, rarely ovate or elliptic, 9–25(–48)≈(2.2–)3–14(–22) mm, apex acute, margin serrate, base obtuse, with (1–)2–9 teeth on each side, nerves 2–4 on each side of the midrib, upper surface with sessile glandular hairs scattered with stellate hairs, lower surface densely covered with simple glandular hairs and stellate hairs; petiole 1–8(–10) mm long; stipules triangular, 1.3–1.8≈0.6–1 mm. Inflorescence with flowers single in the upper axils; peduncle 5.5–18 mm long, indumentum as stem; with 2–3 patent triangular bracts 0.5–1.2≈0.3–0.6 mm at the junction with the pedicel; pedicel 1.5–2(–3) mm long. Flowers pendulous, red, mauve, pink, rarely white or pink with red centre, 5–8 mm wide. Calyx campanulate, 5–6≈5 mm, lobed for 1/2, lobes 3–4.1≈1–1.4 mm, indumentum as stem. Petals obovate or subligulate, (4.2–)5–6≈(1.9–)2.5–3 mm, apex rounded, basal 1/2 to 1/3 ± involute, rarely so involute that petal appears clawed; band of simple hairs above involute zone. Stamens with filaments oblanceolate, 2–3.2≈(0.8–)1.2–1.8 mm, with or without hairs on the distal margin; anthers 2.5–5.5≈0.5–1 mm. Ovary ellipsoid, 1.7–2≈0.9–1.5 mm, truncate, slightly awned, stipe 0.2–0.7 mm; style 3.5–5 mm. Fruit capsule truncate-ovoid, awned, 5–7≈5.5–8 mm, awns patent, 2(–4) mm long, indumentum as stem; seeds reniform, 1.2–1.5≈1–1.2≈1 mm, rugose, densely white papillate.

Notes
LOCAL USES. Eaten by stock (Hornby 17). This species is widespread and common, and its habitat either not significantly threatened or (old cultivation) increasing. It is rated here as of “least concern” for conservation. Most E African material of H. glanduligera has been misidentified as H. kirkii (see key for differences) or as H. viscosa, an Angolan species which lacks the hairy petals of H. glanduligera, as pointed out by Wild in FZ 1: 546 (1961). The indumentum of H. glanduligera is unusually variable in trichome complement for the genus and no assistance to identification. H. glanduligera can be easily recognized within the group of Hermannia in East Africa which are annuals, with single axillary flowers, obovate filaments and awned fruits (H. kirkii, H. modesta and H. tigreensis) by the widely triangular stipules, the presence of bracteoles at the base of the pedicel, the peduncles which are usually only as long or shorter than the leaves and by the petals, which are hairy on the inner surface.
