Genus: GentianaView DescriptionDichotomous Key

Common Name: GENTIAN
Habit: Annual to perennial herb, generally glabrous. Stem: generally simple below inflorescence. Leaf: cauline, opposite (also basal or not). Inflorescence: compact cyme or flowers 1. Flower: parts generally in 5s (generally in 4s in Gentiana prostrata, 4s or 5s in Gentiana fremontii); calyx tube generally > lobes; corolla tube narrow-bell-shaped, lobes spreading, < tube, base of sinus between lobes truncate or generally with a variously shaped, sometimes fringed appendage, nectary pits 0 (nectaries on ovary stalk); ovary stalked, style +- 0 or short, entire, persistent, stigmas 2.
Etymology: (Gentius, king of Illyria, who used roots to treat malaria)
Species: Gentiana newberryiView Description 

Habit: Perennial herb. Stem: arising laterally from caudex, below rosette, decumbent, 1--several, 0.5--10(35) cm. Leaf: basal, lower cauline 8--50(75) mm, 2--25 mm wide, widely spoon-shaped to oblanceolate, rounded or mucronate; upper cauline few, generally > internodes, 6--30(45) mm, 1--8(13) mm wide, oblanceolate to linear, acute. Inflorescence: flowers 2--5 or generally 1. Flower: calyx (10)14--30 mm, lobes linear to narrow-ovate, acute; corolla 23--55 mm, lobes 7--17 mm, elliptic-obovate, short-acuminate, sinus appendages divided into 2 triangular, +- serrate to jagged-cut parts tapered to thread-like tips. Seed: winged.
Note: Varieties intergrade in CaRH, northern SNH (e.g., plants with large stem, leaf, flower and white corollas, or plants with small stem, leaf, flower and blue corollas).
Unabridged Note: Varieties intergrade in central part (CaRH, northern SNH) of sp. range (e.g., plants with stem, leaf, flower in upper part of size ranges for sp. but with white corollas, or plants with stem, leaf, flower in lower part of size ranges for sp. but with blue corollas).

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.
