Name
Lophocarpinia Burkart, Darwiniana 11: 256. 1957 – Wikispecies link – Pensoft Profile
Type
Lophocarpinia aculeatifolia (Burkart) Burkart ≡ Cenostigma aculeatifolium Burkart.
Description
Shrub 0.5 (– 3) m tall, armed with scattered straight, conical, 2–5 mm long spines on shoots; leaves and inflorescences crowded on brachyblasts; shoots glabrous, reddish, the lateral ones sometimes, spinescent. Stipules acuminate, caducous. Leaves alternate, paripinnate, 5–10 mm long; leaflets in 2 (– 3) pairs, obovate or elliptic-orbicular, 4–7 × 2–2.4 mm, finely pubescent, eglandular, with a pair of small prickles at the insertions of the leaflets. Inflorescences short, corymbiform, pubescent racemes, each with 3–6 bisexual flowers; bracts small, caducous. Flowers zygomorphic, 1–1.5 cm long; calyx with a turbinate, fleshy hypanthium, and 5 oblong, pubescent, caducous sepals, lower sepal cucullate and covering the other 4 sepals in bud, embracing the androecium and gynoecium at anthesis; petals 5, yellow to yellow-orange, free, the median petal differentiated from the rest by a fleshy claw and wavy blade margins, pubescent; stamens 10, free, filaments pubescent; ovary glabrous; stigma apical, concave. Fruit a lomentum, with 1–5 segments, falcate, with 4 coarsely serrate wings. Seeds ellipsoid to reniform, smooth.
Geographic distribution
A monospecific genus restricted to Argentina and Paraguay (possibly also occurring in Mato Grosso do Sul, Brazil, pers. comm. H. C. de Lima).
Habitat
Chaco woodland and seasonally dry tropical to subtropical forest.
Etymology
From lopho- (Greek: combed or crested) and carpos (Greek: fruit), the fruit has 4 crested wings, the ending -inia signifies a close relationship with Caesalpinia.
