Genus: LoniceraView DescriptionDichotomous Key


Common Name: HONEYSUCKLE
Habit: Shrub, twining to erect. Leaf: simple, entire, generally short-petioled; 1--2 pairs beneath inflorescence often fused around stem. Inflorescence: spikes, +- interrupted, on axillary peduncles or at ends of branches, or flowers paired on axillary peduncles and subtended by 0--3 pairs of bracts. Flower: calyx limb 0 or generally 5-toothed, generally persistent; corolla 5-lobed, +- bilateral, 2-lipped (upper 4-lobed), swollen at base on 1 side; ovary chambers 2--3. Fruit: berry, generally round; seeds generally > 2.
Species In Genus: +- 200 species: temperate, subtropical North America, Europe, Asia, northern Africa. Etymology: (Johann Lonitzer, German herbalist, physician, 1499--1569, and/or his son, Adam Lonitzer, German botanist, 1528--1586)
Unabridged Note: According to Ferguson (1966 J Arnold Arbor 47:33--59), genus named "in honor of Johann Lonitzer, latinized Lonicerus, 1499--1569, a German herbalist and physician, not Adam Lonitzer, 1528--1586; see Linnaeus, Crit. Bot. 93 1737." In fact, although Linnaeus indicated in Critica Botanica (Hort translation, Ray Society, 1938, p. 76) that the genus Lonicera was named in honor of Johann Lonitzer, in Hortus Cliffortianus (1737; p. 58) he states "...Loniceram ab Adamo Lonicero, antiquo Botanico...".

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.
