Geophytic perennial or suffrutex, mostly 10-50 cm tall; tuber parsnip-like or ovoid; stems decumbent or erect, ± suffrutescent below, basal woody portion 1-2 mm diam. but 0.5-1.5 mm diam. at base of inflorescence, ± densely puberulous-scabridulous with short, deflexed or spreading, acute hairs, rarely sub-glabrous. Leaves cauline but concentrated in lower part of stem, ± abruptly separated from inflorescence, lower sometimes dry or withered, linear to obovate, (10-)15-60 x 1-15(-22) mm, obtuse, apiculate or weakly uncinate, base narrowed,, ± adpressed-puberulous, usually more densely so abaxially, rarely glabrous on adaxial or both surfaces, hairs acute, margins ciliate towards base with longer, straggling hairs to 1 mm long, without evident side veins. Inflorescence a lax or dense, (2)3-12-flowered monochasium terminating main stems, well separated from foliage, simple or with 1(2) branches from base, rachis 0.5-1.0 mm diam.; bracts smaller than leaves, unequal to subequal, oblong or lanceolate to subulate, puberulous with appressed, acute hairs, margins densely ciliolate; pedicels 3-10(-15) mm long, rarely up to 20 mm long in fruit. Calyx clavate in flower, (10-)12-18(-25) x 2.5-4 mm at anthesis, slightly upcurved distal to carpophore when > ± 15 mm long, equally 10-veined, adpressed-puberulous, lobes ovate or triangular, ± 2-4 mm long, densely ciliolate. Flowers ± patent or suberect at anthesis, nocturnal, coconut-scented or more medicinal and acrid. Petals white to pale yellowish, pale pink or mauve, with darker green or maroon reverse, claw 7-8(-10) mm long, rarely exserted up to 6 mm beyond calyx, narrowed below, without evident auricles, pubescent along midrib and veins on outer surface, limb bifid, 3-7 x 2-5 mm, coronal scales 0.2-0.8 mm long. Stamen filaments slightly unequal, 6-10 mm long, shorter series shortly included, longer series reaching top of claw or exserted up to 2 mm. Ovary ellipsoid, ± 4 mm long; styles 4-6 mm long, exserted up to 3 mm. Capsule ovoid, 8-10 x 5-7 mm, slightly longer than to slightly shorter than carpophore, smooth; carpophore 4-12 mm long, pubescent. Seeds 1.0-1.5 mm, reniform with deep hilar notch, flanks flat or somewhat concave, back deeply and narrowly grooved between two undulate wings, reddish brown, testa striate.
More
A herb. It keeps growing from year to year. It has large oval tubers. The plant is covered with short hairs. The stems can be erect or lying over and it often branches low down. It grows 30-40 cm tall. The leaves vary is size and shape. They are narrow and can be oblong or sword shaped. The flowers are in simple loose, one sided groups. There are 2-7 flowers in a group and they are near the ends of the branches. The flower petals can be red, purple or white. The fruit is a capsule on stalks 5-6 mm long. The seeds are flattened and 1.3 mm long.
Erect or sprawling, shortly hairy, tuberous-rooted perennial to 70 cm. Leaves linear-oblanceolate to oblanceolate. Flowers in subsecund, raceme-like, monochasial cymes, white to purple, calyx 10-20 mm long, petals bifid, carpophore 6-9 mm long. Seeds discoid, peripherally winged.
Flowers in simple, lax, one-sided, 2–7-flowered racemes at the ends of the branches; peduncle up to 20 cm. long, usually rather elongate; bracts up to 8 mm. long but often less, subulate to linear-lanceolate; pedicels very short or up to c. 1·5 cm. long on the lowest flowers.
Erect or sprawling, shortly hairy perennial, up to 0.7 m tall, not viscid. Leaves linear-oblanceolate to oblanceolate. Flowers in a ± one-sided, raceme-like cyme, white to purple, calyx 10-25(-35) mm long, petals bifid, carpophore 6-9 mm long.
Petals reddish-brown, purple, pinkish or white, 1–3 (–5) mm. long, often minutely puberulous; claw about the same length as the calyx; limb about half the length of the claw, bifid to about half way; coronal scales whitish, ± semicircular.
Perennial herb with parsnip-like or ovoid-tuberous roots, more or less pubescent with short hairs on all aerial parts; stems erect or ascending, up to 70 cm. tall, branching low down, coastal forms often with procumbent vegetative shoots.
Leaves 1–8 × 0·1–1·3 cm., sessile or shortly petiolate on procumbent vegetative shoots, narrowly linear to oblong-lanceolate or oblong-oblanceolate or rarely obovate, acute or obtuse and mucronate at the apex, cuneate at the base.
Capsule on a stalk up to 6 mm. long, oblong-ellipsoid, enclosed in the persistent calyx but slightly exserted, c. 1 cm. long, opening at the apex by 6 ± recurved valves.
Calyx 1·1–2·5 (3·5) cm. long, tubular-clavate with 10 darker nerves; teeth 2–3 mm. long, lanceolate to ovate, obtuse or acute to shortly acuminate.
Seeds numerous, brown, c. 2 mm. in diam., flattened-reniform with a double marginal wing, smooth or very slightly tuberculate.
Ovary ellipsoid, on a very short stalk; styles 3, 5–7 mm. long, filamentous, hairy.
