Zeltnera venusta

Higher Taxonomy
Family: GentianaceaeView DescriptionDichotomous Key
Habit: Annual to perennial herb [to trees]. Stem: decumbent to erect, < 2 m, simple or branched. Leaf: simple, cauline, sometimes also basal, opposite or whorled, entire, sessile or basal +- petioled; stipules 0. Flower: bisexual, radial, parts in 4s or 5s except pistil 1; sepals fused, persistent; petals fused, +- persistent, sinus between lobes often unappendaged; stamens epipetalous, alternate corolla lobes; ovary superior, chamber 1, placentas parietal, often intruding, stigmas 1--2. Fruit: capsule, 2-valved. Seed: many.
Genera In Family: +- 90 genera, 1800 species: worldwide; some cultivated (Eustoma, Exacum, Gentiana). Note: Gentianella tenella moved to Comastoma. Key to genera revised by Bruce G. Baldwin.

Genus: ZeltneraView DescriptionDichotomous Key

Common Name: CENTAURY
Habit: Annual, glabrous. Stem: erect, generally branched. Leaf: cauline, opposite (sometimes also basal). Inflorescence: cyme. Flower: parts in 4s or generally 5s; calyx lobes >> tube (discounting thin membrane between lobes in Zeltnera davyi), appressed to corolla tube, generally not keeled; corolla salverform, white or generally pink, lobes <= tube, +- entire, scales 0, nectaries pits 0 (nectaries elsewhere 0); stamens often initially curved to 1 side, dehisced anthers spirally twisted; ovary sessile, style generally thread-like, deciduous, entire or cleft < 1 mm, stigmas 1, 2-lobed, or 2, stigmas or lobes wedge- to fan-shaped.
Etymology: (L. Zeltner, N. Zeltner, Swiss botanists, b. 1938, 1934) Note: Variable, difficult; further study needed, especially of chromosome numbers, hybridization. Zeltnera calycosa (Buckley) G. Mans. [Centaurium calycosum (Buckley) Fernald] not in California.

Zeltnera venusta (A. Gray) G. Mans.
Habit: Plant 3--50 cm. Leaf: generally cauline, 5--25 mm, narrow-ovate-oblong to lanceolate. Inflorescence: +- open; pedicels generally 4--25 mm. Flower: corolla (7)16--30 mm, lobes (2)5--20 mm, lanceolate to spoon-shaped or elliptic-obovate, tip obtuse to +- acute; stigmas 2. Chromosomes: 2n=34.
Ecology: Dry grassland, scrub, chaparral, openings in woodland; Elevation: < 1800 m. Bioregional Distribution: KR, s NCoRO, NCoRI, CaRF, SNF, e SnJV, SW (exc n ChI), SNE, DMoj; Distribution Outside California: to Baja California. Flowering Time: May--Aug
Synonyms: Centaurium venustum (A. Gray) B.L. Rob.; Centaurium venustum subsp. abramsii Munz; Zeltnera abramsii (Munz) G. Mans.
Unabridged Note: Highly variable. If recognized taxonomically, plants with narrow, acute corolla lobes assignable to Centaurium venustum subsp. abramsii Munz or Zeltnera abramsii (Munz) G. Mans. They occur sporadically throughout much of the range of Zeltnera venusta, but are more common northward. Intergradation appears to be extensive, but recognition as a variety may be appropriate. Some may be hybrids with Zeltnera trichantha. Plants in SW with pedicels to 50 mm, sometimes several-stemmed from base and/or with +- persistent basal leaves, may be hybrids with Zeltnera exaltata.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
