Species

Angiosperms > Gentianales > Rubiaceae > Fadogiella

Characteristics

Erect subshrub, 0.5–1.2(–1.8) m. tall, with much-branched often 3–4-angled usually single stem or 2–3 stems from a thick horizontal or vertical woody stock; shoots slender, velvety yellowish tomentose above but soon glabrescent and ultimately dull purplish and glabrous.. Leaves predominantly paired or in whorls of 3 at some few nodes bearing 3 side-branches; blades narrowly to broadly elliptic or obovate, or lanceolate, 1.7–8(–10) cm. long, 0.5–4.4(–5.8) cm. wide, narrowed to a rounded or subacute apex, rarely shortly acuneate, cuneate at the base, mostly very discolorous, densely covered with yellowish grey curled short hairs above which do not obscure the surface, ultimately sometimes becoming glabrous, white or yellowish grey velvety tomentose beneath, the surface entirely obscured save in old leaves, venation impressed and ± bullate above and raised and reticulate beneath in mature leaves; petiole 2–3(–6) mm. long; stipules with triangular base, 1–2 mm. long, and subulate appendage, 2.5–3(–6) mm. long, at first tomentose but becoming glabrous.. Inflorescences dense and subsessile, the axillary pairs forming dense nodal clusters; peduncles 0–2.5 mm. long, rarely to 1.5 cm. in fruit; pedicels 1–1.5(–5) mm. long, all densely tomentose; bracts and bracteoles scarious, turning dark brown, ovate or narrowly lanceolate, ± 1 mm. long.. Buds densely tomentose with adpressed hairs, with 5 short but distinct appendages.. Calyx-tube 1–1.5 mm. long, the teeth short, ± triangular, ± scarious, brown, 0.5–1 mm. long, ± glabrous or pubescent.. Corolla green or yellow; tube 3–5 mm. long, densely tomentose outside, shortly hairy at throat; lobes linear-triangular, 4–5 mm. long, ± 2 mm. wide, apiculate, with similar indumentum to tube outside.. Anthers exserted, 1.5–2 mm. long.. Style 6–6.5 mm. long; stigmatic club pale green, subcylindrical, 0.75–1.5 mm. long, 3–5-lobed at apex.. Fruits globose, 0.8–1.2(–1.5) cm. diameter, crowned by tomentose limb, shiny, glabrescent or glabrous, with (1–)3–5 pyrenes.. Figs. 132/8, p. 754; 140, p. 785.

An erect shrub. It grows 1.2 m tall. It has a thick woody rootstock. The stems can be single or divided into 2 or 3. The branches are 3-4 angled. The young shoots are slender with a yellow coating that gets removed. The leaves are in pairs or rings of 3. The leaves are 2-8 cm long by 1-4 cm wide. They are narrowly oval and have short yellow hairs. The fruit are round and 8-12 mm across.
Corolla with 5 short but distinct appendages in bud; green or yellow, densely tomentose with appressed hairs; tube 3–5 mm long, densely tomentose outside, shortly hairy at the throat; lobes 4–5 mm long, c. 2 mm wide, linear-triangular, apiculate, with similar indumentum to tube outside.
Inflorescences dense and subsessile, the axillary pairs forming dense nodal clusters; peduncles 0–2.5 mm long, rarely to 15 mm in fruit; pedicels 1–1.5(5) mm long, all densely tomentose; bracts and bracteoles c. 1 mm long, ovate or narrowly lanceolate, scarious, turning dark brown.
Erect suffrutex, 0.5–1.2(1.8) m tall, from a thick horizontal or vertical woody rootstock; stems usually single, or 2–3, much branched often 3–4-angled; shoots slender, velvety yellowish-tomentose above but soon glabrescent and ultimately dull purplish and glabrous.
Fruits globose, 7.5–12(15) mm in diameter, crowned by a tomentose calyx limb, shiny, glabrescent or glabrous, with (1)3–5 pyrenes.
Calyx tube 1–1.5 mm long, the teeth short, 0.5–1 mm long, ± triangular, ± scarious, brown, ± glabrous or pubescent.
Pollen presenter pale green, 0.75–1.5 mm long, subcylindrical, 3–5-lobed at apex.
Anthers exserted, 1.5–2 mm long.
Style 6–6.5 mm long.
