280 CAPRIFOLIACE^E. Lonicera. 



5. LONICERA, Linn. Honeysuckle. Woodbine. 



Calyx minutely 5-toothed. Corolla tubular, funnelform, or oblong-campanulate ; 

 the tube commonly gibbous at base ; the limb irregularly or sometimes almost regu- 

 larly 5-lobed, often bilabiate (^, i. e. 4 lobes in the upper, 1 in the lower lip). Sta- 

 mens 5, inserted on the tube of the corolla. Ovary 2 - 3-celled, with numerous 

 ovules in each cell : style filiform : stigma capitate. Berry several-seeded. Twin- 

 ing or erect shrubs, with scaly buds, and spicate or geminate flowers. Leaves 

 entire, or occasionally sinuate-pinnatifid on vigorous young shoots. 



Genus widely dispersed over the northern hemisphere, several cultivated for ornament and 

 fragrance, especially the European Honeysuckles, L. Caprifolium and L. Etrusca ; the American 

 Trumpet H., L. sempervircns, which has an almost regular corolla ; Chinese or Japan H, L. Ja- 

 ponica, etc. ; and, among the upright species, L. Tartarica, the Tartarean Honeysuckle. 



L. ciliosa, Poir., a common Oregon species with corolla slightly bilabiate, may occur in Cali- 

 fornia. Apparently a form of it, with rather smaller leaves and flowers, was collected on San 

 Francisco Mountain, in Arizona, by Dr. Palmer. 



§ 1. Stems or branches more or less tivining or disposed to twine : flowers sessile in a 

 terminal interrupted spilce or head, or some in the axils of the v.prper {and com- 

 monly connate) leaves, usually rather large and showy : calyx-teeth persistent 

 on the {red or orange) berry : corolla in all the Californian species decidedly 

 bilabiate, the upper lip ^-lobed, the lower narrow and entire. (Sometimes 

 there are foliaceous stipules or what seem to be such between the leaves.) — 

 Capeifolium, DC. 



1. L. hispidula, Dougl. in Bot. Eeg. Foliaceous stipular appendages between 

 the leaves often present : leaves mostly oval, the lower short-petioled ; uppermost 

 pairs commonly connate : spikes naked, slender : corolla pink or yellowish ; its tube 

 hairy inside, not longer than the limb : stamens and especially the long style ex- 

 serted, more or less hairy at base. — All the Californian specimens seem to belong 

 to one species, of which this is the oldest name. — Gray, Proc. Am. Acad. viii. 627. 

 The leading forms are : — 



Var. Douglasii, the first described form, from Oregon : leaves (£ - 1 A- inches long) 

 at least beneath and their margins and slender branches hirsute or pubescent with 

 spreading hairs : inflorescence and pink flowers glabrous. — L. microphylla, Hook. 

 Fl. i. 283. Caprifolium hispidulum, Lincll. Bot. Beg. t. 1761. 



Var. subspicata : a bushy form, along the coast from Monterey Bay to San 

 Diego, seldom climbing, with small leaves more or less pubescent, the uppermost 

 often distinct ; the branchlets, inflorescence, and flowers glandular-pubescent. — L. 

 subspicata, Hook. & Arn. Bot. Beech. 349 ; Torr. Bot. Mex. Bound. 71, t. 29. 



Var. interrupta: resembling the preceding, but glabrous throughout, often 

 glaucous : filaments slightly hairy at base. — L. interrupta, Benth. PI. Hartw. 313. 



Var. vacillans : mostly climbing, larger, either glabrous or pubescent, with or 

 without hirsute hairs : inflorescence and flowers glandular-hirsute or pubescent, 

 varying to glabrous. — L. Californica, Torr. & Gray, PI. ii. 7. L. ciliosa, Hook. & 

 Arn., not of Poir. L. pilosa, Kellogg, Proc. Calif. Acad. i. 62. 



Common throughout the State, on hillsides, &c. Corolla about half an inch long. 



§ 2. Stems in the American species erect, never twining : all the leaves distinct : flowers 

 a pair (sessile or their bases united) at the summit of an axillary peduncle. — 

 Xtlostetjm, DC. 



2. L. involucrata, Banks. Pubescent, leafy : leaves varying from ovate- 

 oblong to broadly lanceolate, mostly acuminate, thin, petioled : peduncles shorter 

 than the leaf : bracts 4 to 6, forming a conspicuous foliaceous involucre : corolla 

 tubular, with short lobes, viscid-pubescent, yellowish : ovaries and black-purple
