Huernia pillansii
ENGLISH: Cocklebur, Cockle burrs
CHINESE (中文): 阿修罗
RUSSIAN (Русский): Гуэрния ВолосистаяDescription: Huernia pillansii is one of the most distinct species of this genus, no other having similar bristle-covered stems, which resemble those of a Hoodia in miniature. Several forms of this species exist and may just be considered as forms as none are distinct enough to justify naming them. Justly popular for its stems and showy star-like blooms. The flowers are somewhat like those of Huernia hystrix.
Habit: It is a densely tufted carpeter plant.
Stems: Soft 2-5 rarely to 18 cm, long, 12–20 mm in diameter, erect or ascending, subglobose when young, becoming narrowly ovate or cylindric.
Tubercles: Small, crowded, conical recurved bristle-pointed tubercles 2-4(-8) mm long, in 9-16 (rarely to 24) vertical or spiral series, glabrous, green, or dull purplish where exposed to the sun.
Leaves: Rudimental 2-8 mm long, as soft bristles more or less divaricate. usually marcescent.
Flowers: 1–3 together near the base of the young stems, successively developed 1-5 cm in diameter with a cup-like tube mostly facing upwards.
Pedicels: 3-4(-8) mm long, glabrous.
Sepals:(4-)6-8(-12) mm long, 1,5-2 mm broad, ovate-anceolate at the base, attenuate into filiform recurving tips, glabrous.
Corolla: 2,5-5 cm diameter, outside yellow or reddish brown, inside cream-coloured or yellowish, stippled with irregular blotches of red or maroon.
Tube: Cylindrical, campanulate, (at times cup-shaped) with labyrinth-like reddish dots, 5 - 9 mm long and as much in diameter outside.
Lobes: Triangular, abruptly and horizontally spreading from the tube or revolute, 10-12(-22) mm long, 6-7(-10) mm broad at the base, whence they gradually taper to a fine acuminate point, glabrous outside. Inner surface and margins densely papillose covered on the lobes and in the throat of the tube with small fleshy terete obtuse erect processes 0,5-1 mm long, smooth in the lower part of the tube, pale yellow, becoming pinkish-cream in the tube, covered with small crimson spots and the tips of the processes also crimson.
Outer corona: 5-lobed, black or purple-black; lobes about 1,5-2,5 mm long and broad, subquadrate or oblong, very shortly and obtusely bifid to acutely bifid to the middle, when the whole appears to consist of 5 pairs of small deltoid teeth.
Inner corona-lobes: About 2-2,5 mm long, tapering from a swollen base to a knob-like tip. trapezifom, connivent-erect, with very slightly spreading tips, dorsally flattened, linear, slightly humped at the base, acutely verrucose, at the obtuse slightly thickened apex, dark purple-brown.
Staminal column: About 3 mm long yellowish to greenish germination mouth region darker.
Blooming season: It flowers freely in late summer and early autumn.
Fruit: Paired follicles.
Seeds: Numerous, strongly compressed, with a coma (a prominent basal tuft of silky hairs).www.llifle.com/Encyclopedia/SUCCULENTS/Family/Asclepiadaceae/21248/Huernia_pillansii'식물 > 들꽃-협죽도과(Apocynaceae)' 카테고리의 다른 글
