Wahlenbergia pulchella Thulin

Species

Angiosperms > Asterales > Campanulaceae > Wahlenbergia

Characteristics

Annual ± erect often ± spreading or straggling herb, 5–40 cm. tall.. Stem with few to many usually long branches, rarely unbranched, ± hirsute along its entire length or glabrous in the upper part, rarely all glabrous.. Leaves linear to ovate (basal leaves usually short and broad), up to 7–40 mm. long, 1.5–10 mm. wide, acute to subacute, with cuneate to truncate base, ± hirsute, especially beneath; margin cartilaginous, ± dentate; midvein prominent beneath, lateral veins ± obscure.. Inflorescence lax or with flowers in ± dense axillary and terminal clusters; flowers subsessile or on glabrous or hairy pedicels up to 20 mm. long.. Hypanthium ± obconical, ± 10-nerved, ± hairy or glabrous.. Calyx-lobes 0.8–3.2 mm. long, ± ciliate-pubescent or glabrous; margin cartilaginous.. Corolla 3–6.5 mm. long (outside East Africa 1.5–7 mm.), blue, white or yellow, split almost to the base into linear lobes, ± hairy or glabrous outside.. Filament-bases ± broadly dilated, ciliate; anthers 0.5–1.6 mm. long.. Ovary 3-locular, semi-inferior; style about as long as or somewhat shorter than the corolla, eglandular, slightly thickened in the upper part, glabrous or rarely hairy below; lobes 3, 0.3–0.6 mm. long.. Capsule 3-locular, ± 10-nerved; valves 3, 0.8–2.5 mm. long.. Seeds elliptic-oblong in outline, compressed, 0.4–0.7 mm. long; testa almost smooth.
