Taxonavigation

Ordo: Fabales
Familia: Leguminosae

Name

Hoffmannseggia Cav., Icon. 4: 63. 1798 – Wikispecies link – Pensoft Profile

Type

Hoffmannseggia falcaria Cav., nom. illeg. = Hoffmannseggia glauca (Ortega) Eifert.

Description

Perennial woody herbs, most species forming a basal rosette, or subshrubs to 3 m, unarmed, often arising from bud-bearing and tuberous roots, shoots pubescent and with gland-tipped trichomes. Stipules not seen. Leaves alternate, bipinnate, ending in a pair of pinnae plus a single terminal pinna (except for Hoffmannseggia aphylla); pinnae opposite, in 1-13 pairs; leaflets small and numerous, in 2–15 (– 18) pairs per pinna, glabrous to pubescent, and glandular. Inflorescences terminal or axillary racemes; bracts often caducous. Flowers bisexual, zygomorphic; calyx comprising a hypanthium and 5 sepals, these weakly imbricate, persistent as pods mature (except in Hoffmannseggia microphylla and Hoffmannseggia peninsularis, where they are not always persistent); petals 5, free, yellow to orange, the median petal often with red markings; stamens 10, free, filaments pubescent; ovary glabrous to pubescent, eglandular to glandular, stigma apical, concave. Fruit a laterally compressed, straight or sometimes falcate pod, the sutures almost parallel, papery to leathery, glabrous to pubescent, eglandular or with glandular trichomes, indehiscent or dehiscent, with twisting valves. Seeds compressed, ovoid.

Geographic distribution

Hoffmannseggia comprises 25 taxa in 23 species and occupies a classical amphitropical distribution in the New World with 10 species restricted to North America (southern USA and Mexico), 12 in South America (Peru, Bolivia to south-central Argentina and Chile, mainly Andean), and one species (Hoffmannseggia glauca (Ortega) Eifert) widespread throughout the range of the genus.

Habitat

Subtropical desert and semi-desert grassland, often in open areas and on disturbed sites, on sandy, rocky or calcareous soils.

Etymology

Named by Cavanilles for the German botanist, entomologist and ornithologist, Johann Centurius Graf von Hoffmannsegg (1766–1849).
