Common name:

Latin name and synonyms: Zeltnera Mansion (2004)

Etymology: Zeltnera is dedicated to both Dr. Louis Zeltner (1938-) and his wife Nicole (1934-), from Le Locle, Switzerland. These two botanists have greatly contributed to the systematics of the genus Centaurium and related genera.

Species: 25 species

Distribution: Western North America, Central America, and northern South America.

Habitat: Chaparral and creosote bush scrub, coastal sage scrub, grasslands, moist places along streams, pine oak-forest.

Characteristics: Annual or biennial herbs (one perennial). Leaves glabrous, linear to elliptic, sometimes with glandular hairs. Flowers 5-merous. Inflorescence a simple or compound, dense or lax cyme (sometimes a panicle or a raceme). Calyx tube much shorter than the calyx lobes. Corolla white to rose-pink or magenta, salvershaped; corolla tube longer than or equaling the corolla lobes. Anthers helically twisted after dehiscence. Pollen released as monads. Style not divided beneath stigmata surface. Stigma lobes rhombic to fan-shaped (sometimes subcapitate), not fleshy. Fruit a capsule elliptic to oval in shape. Chromosome number: n = 17, 20, 21, 22, 37.

Evolution and related plants: Zeltnera belongs to subtribe Chironiinae in tribe Chironieae. The closest relatives are the genera Exaculum and Schenkia, which occur in the Mediterranean region and Australia (Schenkia p.p.).

Economic uses:

Notes: This genus was recently described as a segregate of Centaurium by Mansion (2004), following work that showed that Centaurium consisted of 4 independent groups. The other two segregate genera that are now accepted are called Schenkia and Gyrandra.
