(For a list of species in Lonicera, use the above link.) Jepson Manual glossary definitions can be seen by moving your cursor over words underlined with dots. 1. Flowers paired on axillary  Pertaining to or within an axil, especially a leaf axil. peduncles  Stalk of an individual flower borne singly, not in an inflorescence, or of an entire inflorescence, or the corresponding structure in fruit; the stalk subtending an involucre (e.g., in Asteraceae, Polygonaceae). ; plants twining or erect  Upright; vertically oriented. 2' Corolla < 20 mm; plant erect 3. Ovaries of flower pair fused or appearing so 4. Corolla ± yellow, weakly 2-lipped; bracts 1–3 pairs, narrowly lanceolate  Narrowly elongate, widest in the basal half, often tapered to an acute tip. ; ovaries, fruit tightly enclosed by inner, fused bracts, thereby appearing fully fused ..... L. cauriana 4' Corolla dark red, strongly 2-lipped; bracts 0 or minute; ovaries, fruits not enclosed by bracts, fused generally > 1/2 ..... L. conjugialis 3' Ovaries of flower pair free 5. Bracts not leaf-like, not forming involucre  Group of bracts more or less held together as a unit, subtending a flower, fruit (acorn cup), or inflorescence. , not enveloping ovaries ..... L. tatarica 6. Plant 6–9 dm; corolla yellow, tube ± wider upward; stigma exserted  Protruding out of surrounding structure(s) (e.g., stamens exserted from corolla). ; KR, NCoRH, CaRH, SN, MP ..... var. involucrata 6' Plant 15–36 dm; corolla yellow, strongly tinged orange or red, tube cylindric  Elongate, with parallel sides and, at any point, round in transverse section. ; stigma included  Not protruding out of surrounding structure(s) (e.g., stamens included in corolla). or ± exserted; NCo, NCoRH, NCoRI, CCo ..... var. ledebourii 1' Flowers in ± interrupted spikes on axillary peduncles or at ends of branches; plants twining or trailing (except Lonicera interrupta) 7. Leaf 5–10 cm; corolla 15–50 mm; inflorescence a dense, short spike  1. In flowering plants excluding Asteraceae, Cyperaceae, Poaceae, and some other groups, an unbranched inflorescence in which the flowers are sessile and nearly always open from the bottom to the top of the inflorescence. 2. In Asteraceae, Cyperaceae, Poaceae, and some other groups, a spike-like inflorescence is one in which the inflorescence units (e.g., heads in Asteraceae; spikelets in Cyperaceae and Poaceae), instead of individual flowers, are sessile and attached directly to the main axis of the inflorescence, not to branches, and in which floral development may or may not proceed as in 1. ; upper leaf  Organ arising from a stem, generally composed of a stalk (petiole) and a flat, expanded, green, photosynthetic area (blade); distinguished from a leaflet by the presence in its axil of a bud, branch, thorn, or flower; sometimes with lateral, basal appendages (stipules); either simple (toothed, lobed, or dissected but not divided into leaflets) or compound (divided into leaflets). pair fused around stem; NW, CaR 8' Corolla yellow-white tinged ± purple, strongly 2-lipped; stamens, style well exserted ..... [L. etrusca] 7' Leaf 1–8 cm; corolla generally < 15 mm; inflorescence a ± long, interrupted spike; upper leaf pair fused around stem or not; widespread 9. Upper leaf pairs fused around stem; corolla glabrous or not 10. Stipules ± conspicuous, at least near inflorescence; corolla glandular-hairy or hairy ..... L. hispidula
