Type
Type: Tanzania, Ulanga District, Sali, Schlieben 1878a (B†, holo.)
Morphology General Habit
Monocarpic acaulescent herb
Morphology Leaves
Unifoliate, leaf often pendant; blade ovate to oblong, 6–35 cm long, 3.5–21 cm wide, base cordate, rarely attenuate, margin shallowly crenate-serrate, apex usually withered, spreading-pubescent, particularly on the upper surface and nerves beneath; lateral nerves 11–22 pairs, parallel, spreading, impressed above, raised beneath; petiolode less than 1 cm long, pubescent
Morphology Reproductive morphology Inflorescences
Inflorescences solitary or up to 4(–7), arising from the petiolode, erect, 5–40-flowered, panicles subcorymbiform or rarely more elongate; peduncles 3–15(–22) cm long, eglandular-pubescent, the hairs in the lower part longer anddeflexed; pedicels 7–22 mm long, shortly pubescent; bracts ovate-lanceolate to oblanceolate, 4–6(–9) mm long, pubescent
Morphology Reproductive morphology Flowers Calyx
Calyx lobes oblong-lanceolate, 1.5–3.5 mm long, shortly pubescent on both surfaces
Morphology Reproductive morphology Flowers Corolla
Corolla white to pale lavender-blue, the latter sometimes restricted to the inner limb, 22–35 mm long, shortly eglandularpubescent outside; tube cylindric, 17–30 mm long, (3–)4–5.5 mm deep, scarcely widened to the open mouth, slightly downcurved towards the apex, glabrous within; limb only slightly oblique, lobes small in relation to tube, spreading; upper lip of two rounded lobes, 2–4.5 mm long, (2–)3–5.5 mm wide; lower lip 5–10 mm long, lobes rounded, 3–6 mm long, (2.5–)4–6 mm wide
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens arising from the upper third of the corolla tube.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments 3–4 mm long, thickened centrally, glabrous.
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anther thecae subtriangular to rounded, 0.75–1 mm wide, pale purple-tinged.
Morphology Reproductive morphology Flowers Androecium Staminodes
Staminodes minute
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary cylindric, 11–16 mm long, densely shortly eglandular-pubescent, the hairs somewhat spreading; narrowing into the style, white, 4–8 mm long, pubescent.
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigma shallowly bilobed, 0.9–1.2 mm wide, papillose
Morphology Reproductive morphology Fruits
Capsule slender, 40–80 mm long, 1–2 mm diameter, sparsely pubescent
Morphology Reproductive morphology Seeds
Seeds 0.4–0.65 mm long, reticulate.
Ecology
Epiphytic in forest or lithophytic on shaded or exposed rock faces; (1150–)1350–2100 m
Conservation
This species is somewhat local in distribution. However, it has significant populations in several highland areas of southern Tanzania, northern Malawi and eastern Zimbabwe, appearing rare only in eastern Zambia. It is an adaptable species, being at home in both closed forest as an epiphyte, and in exposed, rocky environments. The latter are largely unthreatened by anthropogenic factors, thus this species is assessed as of Least Concern (LC)
Note
Corolla colour in this species displays significant geographic variation. Within our region, plants from the northern and eastern parts of the range, for example in Morogoro and Ulanga Districts, have exclusively white corollas, whereas those from further south, such as in Songea District tend to be pale lavender-blue, at least on the limb, the tube often remaining whitish.
Distribution
Range: Southern Tanzania to northern Malawi and eastern Zambia with an isolated population in eastern Zimbabwe Flora districts: T6 T7 T8
