DescriptionHABIT Perennial, deciduous, woody vines, monoclinous, 1-3 m tall.
STEMS Main stems prostrate or climbing, round. Bark smooth, not exfoliating, light brown or yellowish green or gray. Branches erect or ascending. Twigs light brown or yellowish green or gray (occasionally purplish), terete, 1.5-4 mm in diam., smooth, glabrous, usually glaucous. Sap translucent. For a detailed analysis of the root anatomy see Gasson, 1979.
BUDS Terminal and axillary present, scattered along stem; terminal bud ovoid, pointed; axillary buds 1 per axil, ovoid, pointed. Bud scales light green or green, imbricate, glabrous. Bud scale scars not encircling the stem. Leaf scars thinly crescent-shaped. Vascular bundle scars 3.
LEAVESOpposite, simple, spaced somewhat evenly along and divergent from stem. Stipules absent. Leaves short petiolate or sessile, petiole terete, glabrous. Leaf blades: abaxial surface white (glaucous), adaxial surface green, elliptic or oblong or ovate or obovate or rhombic, bilaterally symmetric, 4-13 cm long, 1-7 cm wide, base acute or cuneate or obtuse or uppermost pair(s) connate-perfoliate. Margin entire or often undulate cartilaginous and transparent. Apex acute or obtuse; abaxial surface glabrous; adaxial surface glabrous.
INFLORESCENCESSerotinous, formed on last season's growth, bisexual, simple, terminal, 1-2 whorled spike. Peduncle 0.6-1.5 cm long, glaucous, glabrous. Rachis present. Bracts sessile, light greenish yellow, triangular, 1-1.5 mm long, margin entire, apex acute or obtuse, surfaces glabrous. Flowers sessile. Bracteoles often obsolete or 1 or 2, bracteoles: light yellowish green, obovate, 0.5-1 mm long, margin entire, apex obtuse, glabrous.
FLOWERSWith sepals and petals readily distinguishable from one another, 5-merous. Calyx actinomorphic, of fused sepals, persistent, abaxial and adaxial surfaces light yellowish green. Sepal lobes 5, triangular, 0.5-1 mm long, margin entire, apex acute or obtuse, glabrous. Corolla zygomorphic, of fused petals, deciduous, abaxial and adaxial surfaces yellowish orange or light yellow or yellow (often tinged with purple), 15-25 mm long; gibbous near base. Petal lobes 5, margin entire, apex obtuse, abaxial surface glabrous; adaxial surface with long and unbranched hairs; (rarely hairy and/or glandular on some varieties mostly encountered in areas to the west of the NYMF range). Gynoecium syncarpous. Locules 2-3. Stigmas 1, capitate. Styles 1, glabrous. Ovary inferior, glabrous. Placentation axile. Androecium epipetalous, haplostemous, inserted near the top of the corolla tube. Stamens 5; anthers opening along the long axis; filaments straight, glabrous. For a detailed analysis of the flower micro-anatomy and vascularization see Wilkinson, 1948.
FRUITS Bacca, red or orange-red, globose, 8-12 mm in diameter, glabrous.
SEEDS Seeds 3 to 8, yellow, ovoid, 3-4 mm long, 2-2.5 mm wide, glabrous, reticulate-foveate.
HabitatDry to moist woods, banks, slopes; also alluvium and swamps.

Natural germination is believed to occur in the spring following autumn/winter dispersal. This species apparently has little or no seed dormancy. Germination is epigeous. While definite information for the optimum storage of Lonicera seeds is lacking; generally, seed stored in a sealed container at 41 degrees F should remain viable for at least one year.
