Descriptions

Malvaceae, A. W. Exell. Flora Zambesiaca 1:2. 1961

Morphology General Habit
Biennial herb 0·5–1 m. tall; stems shortly stellate-pilose.
Morphology Leaves
Leaf-lamina 4–11 cm. in diam., of basal leaves reniform, of cauline leaves suborbicular and 5-lobed with rounded lobes on lower ones and those of upper ones triangular, margin crenulate-dentate; petiole 4–8 cm. long, longitudinally sulcate, glabrescent except that the grooves remain tomentose; stipules ovate-lanceolate.
Morphology Reproductive morphology Flowers
Flowers in fascicles; pedicels unequal, the longest up to about 3 cm., shortly stellate-pilose.
Morphology Reproductive morphology Flowers Epicalyx
Bracts of epicalyx 5–6 mm. long, linear, ciliate.
Morphology Reproductive morphology Flowers Calyx
Calyx somewhat inflated, sparsely stellate-hirsute; lobes triangular, acute.
Morphology Reproductive morphology Flowers Corolla
Petals about twice as long as the calyx; claw glabrous or with a few weak hairs.
Morphology Reproductive morphology Flowers Androecium Stamens
Staminal tube setose in upper portion.
Morphology Reproductive morphology Fruits
Mericarps 10–12, dorsally smooth or faintly rugose, rugose along the rounded angles, flabellately striate on the flat lateral sides.

Type
Type: China, Syria, Herb. Linn. 870.26 (LINN, lecto.)
Morphology General Habit
Annual or biennial herb 0.5–2.4 m tall, erect, decumbent or ascending, pubescent.
Morphology Stem
Stems somewhat woody at base; the ‘stellateness’ of the hairs on foliage and calyx etc varies considerably, the hairs being almost simple to very distinctly stellate
Morphology Leaves
Leaves cordate to reniform in outline, 4–24(–30) cm long and wide, shallowly 5–7-lobed, the lobes triangular, acute to rounded, crenate to denticulate; petiole 3–20 cm long
Morphology Reproductive morphology Flowers
Flowers in dense axillary clusters merging into interrupted panicles; pedicel 0–7(–18 in fruit) mm long(–30 fide Exell); epicalyx lobes lanceolate, 5 × 2 mm; calyx 4–5 mm long, later accrescent, scarious and reticulate attaining 12 × 15 mm in fruit; lobes triangular, acute
Morphology Reproductive morphology Flowers Corolla
Petals pink, mauve, pale bluish lilac or white with pink tips, 6–10 mm long
Morphology Reproductive morphology Fruits
Mericarps 10–13, 1.5–2 mm long, usually glabrous (see note); back smooth or slightly ribbed near edges; sides with stronger ridges
Figures
Fig 20, p 108
Ecology
Bushland, forest, upper edges of bamboo zone, ericaceous and alpine zones, banks of mountain streams, cultivations, waste and fallow ground, roadsides; 1200–4050 m
Note
This must have been widespread at an early date – already in West Uganda during last decade of 19th Century. It penetrates right into alpine zone e.g. Hedberg 894 from northern slope of Koitobos, Mt Elgon. Has been used as a pot herb and vegetable. Grimshaw 93757 (West Kilimanjaro, 24 Sep. 1993) is a distinctive form with pubescent mericarps and Hepper & Jaeger 7049 (Mt Kulal, Gatab, 24 Nov. 1978) appears to be the same and also probably Bally 5555 (also from Mt Kulal in forest glade near waterhole at 1905 m, 9 Oct. 1947). Bally had named his plant M. verticillata; Gillett had named it M. parviflora, Abedin cf. M. rotundifolia and Krebs cf. pusilla demonstrating how difficult these weedy Malva’s are. The mericarps of Bally 5555 are not rounded at the edges. More extensive and better material with corollas and fruits may solve the true identity of these plants. M. neglecta Walls. has mericarps dorsally ± smooth and pubescent but is much less robust with much more slender stems.
