Characteristics

A geophyte with exposed parts poorly developed, deciduous, unarmed, up to 600 mm tall when in flower. Exposed stems smooth, hard and woody, densely strigose and hirsute with scattered glandular hairs, initially green but turning brown with age, up to 500 mm long and 5-10 mm thick. Leaves basal, simple to (3-)5(-7)-pinnatifid to pinnatisect or occasionally 3-foliolate, lamina decurrent along petiole, coriaceous, conspicuously ciliate, glabrous but occasionally densely pubescent, glaucous; lamina ovate to cordiform in outline, base cordate, apices of segments rounded to almost acute, 35-120 x 30-130 mm; petiole up to 200 mm long, deciduous; stipules cordiform to ovate with apices acute, 4-10 x 3-8 mm, membranous becoming scarious, conspicuously ciliate, abaxially densely strigose becoming glabrous, with sparse glandular hairs. Inflorescence a stout unbranched peduncle 100-150(-400) mm long and up to 3 mm in diameter, carrying a pseudo-umbel of 5-10(-18) almost regular flowers. Pedicel much shorter than hypanthium: 2-20 mm long, densely strigose and with glandular hairs. Hypanthium 20-50 mm long. Sepals narrowly ovate with apices acute, practically glabrous but hirsute at apices and villous along adaxial margins, yellow-green to brown tinted with red, margins hyaline, 7-10 x 1-2 mm. Petals 5, dull yellow, spathulate; posterior two 10-14 x 3-6 mm, reflexed at ±90° near base and slightly indexed at apex, without markings or streaked with purple-black; anterior three slightly narrower: up to 5 mm wide, orientated similarly to posterior petals but less markedly reflexed, with entire central area uniformly purple-black leaving only a narrow dull yellow margin. Fertile stamens 6 (4 long, 2 short and equalling staminodes), pollen bright yellow. Ovary pear-shaped, 4-5 x 2 mm, densely covered in apically-directed hairs, pale green; style ±2 mm long; stigma 5-branched, deep maroon; mericarp base 8-9 mm long, tail 35-45 mm long. Plants flower from July to the following April, but predominantly from September to March. It is deciduous during the winter months.
