Type.

Zuccagnia punctata Cav.

Description.

Shrubs. Stipules caducous (not seen). Leaves pinnate; leaflets 5-13 pairs, subopposite, with glandular dots on both surfaces of the leaflet blades. Inflorescence a terminal, erect raceme. Flowers bisexual, zygomorphic; the calyx (hypanthium and sepals) persistent at fruit maturity; sepals 5, glabrous; the lower sepal cucullate and covering the other four in bud; petals 5, free, yellow, glandular trichomes on the dorsal surface of the petal blades; stamens 10, free, pubescent; ovary pilose. Fruit ovoid-acute, oblique, laterally compressed, indehiscent, 1-seeded, gall-like, on a short stipe and covered with long reddish-brown bristles at maturity. Seeds laterally compressed.

Chromosome number.

2 n = 24 ( Fedorov 1969).

Included species and geographic distribution.

Monospecific ( Z. punctata ), restricted to north-western and central-western Argentina (Fig. 44 ).

Ecology.

Dry temperate upland and montane bushlands and thickets on sandy plains.

Etymology.

Named by Cavanilles for the Italian physician, traveller and plant collector, Attilio Zuccagni (1754-1807).

Human uses.

Minor local medicinal uses; the leaves yield a yellow dye ( Lewis 2005b).

Notes.

Although recorded and described from Chile in the 19th Century, the genus has been cited as doubtful for the flora of Chile ( Marticorena and Quezada 1985; Ulibarri 2005).

Taxonomic references.

Burkart (1952); Gagnon et al. (2016); Kiesling et al. (1994); Lewis (2005b); Nores et al. (2012); Ulibarri (2005, 2008).
