Morphology General Habit
Erect or sometimes decumbent herb 10–18 cm. tall, presumably with several shoots from a woody rootstock.
Morphology Stem
Stems covered with a mixture of longer and shorter white or yellowish spreading hairs.
Morphology Leaves
Leaflets 3, ovate or ovate-oblong in outline, 1–3·5 cm. long and wide, the terminal one ± 3-lobed, the lateral ones with an outer lobe, all obtuse at the apex, broadly rounded or truncate at the base, margins very coarsely crenate, somewhat bullate, shortly pilose above and on the main nerves beneath, also with relatively large scattered orange gland-dots beneath; petiole 1–3·3 cm. long; rhachis 0·5–1·2 cm. long; petiolules 2 mm. long; stipules persistent, ovate-lanceolate, 5–9 mm. long, 2–4 mm. wide, pilose.
Morphology Reproductive morphology Inflorescences
Inflorescences axillary, 10–15-flowered; rhachis 3–7 cm. long, with white and yellowish glandular hairs mixed; peduncle 2·5–9 cm. long; pedicels 1–2 mm. long; bracts deciduous, lanceolate, 3·5–4 mm. long, 1 mm. wide.
