Perennial decumbent, straggling or semiprostrate herb up to 7.5 dm. long; rootstock usually tuberous, up to 1.4 cm. in diameter; stems slender, herbaceous, hollow, mostly covered with a deflexed pubescence intermingled with long patent hairs, angled and often swollen at the nodes; internodes sometimes much reduced in length.
Morphology Leaves
Leaves may be opposite, sometimes alternate especially the lower ones, frequently in basal rosettes; lamina 3- or 5-partite, hastate in outline, 2.5–12.2 cm. long, 2–10.5 cm. wide, long-haired; petiole 1.5–18 cm. long, covered with short intermingled with long hairs; stipules linear-lanceolate, 5–10(–15) mm. long, 2–3 mm. wide at the base, long-haired on the abaxial surface and along the margins, subglabrous on the inner surface, cuspidate (sometimes bifid) at the apex.
Morphology Reproductive morphology Inflorescences
Inflorescence of (2–)4–9 flowers; peduncles 6–36 cm. long, mostly leaf-opposed, pubescent with short and long hairs; free part of the pedicel 2–6 mm. long; bracts usually more than the number of the flowers, linear-lanceolate, 5–10 mm. long, 1–1.5 mm. wide, covered with few but long hairs.
Morphology Reproductive morphology Flowers Calyx
Sepals linear-lanceolate, lorate or narrowly oblong, 6–12 mm. long, 1–3 mm. wide, glandular and rather pubescent, ciliate and hyaline along the margins.
Morphology Reproductive morphology Flowers Spur
Spur 15–35 mm. long, adnate nearly to the base, hispid and glandular.
Morphology Reproductive morphology Flowers Corolla
Petals 5, oblong-spathulate, greenish-yellow, creamy-green, pale lemon greenish-white, or just green with purple veining at the base of the posterior petals, the 2 posterior ones 9–16 mm. long, 4–6 mm. wide, the 3 anterior ones 7–12 mm. long, 3.5–5 mm. wide.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens connate at the base for 1–2.5 mm., crimson to purple; antheriferous filaments 7, 2–5 mm. long; staminodes 3, 1–1.8 mm. long; anthers 1.1–1.6 mm. long, 0.6–0.8 mm. wide, red.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary tomentose (woolly); rostrum indistinct at the flowering stage; style 0.5–1 mm. long; stigmas 1.2–1.6 mm. long, pink-red.
Morphology Reproductive morphology Fruits
Fruit 2.5–5.2 cm. long, at maturity equal or slightly longer than the spur plus pedicel, pubescent; mericarps 6.5–8 mm. long, 1.5–2 mm. wide.
Morphology Reproductive morphology Seeds
Seeds 3.9–4.4 mm. long, 1–1.3 mm. wide; testa minutely reticulate, pale brown.
