280 CAPRIFOLIACEJ3. 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 twining or disposed to twine : flowers sessile in a 

 terminal interrupted spike or head, or some in the axils of the upper (and com- 

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

 on the (red or orange) berry : corolla in all the Calif ornian species decidedly 

 bilabiate, the upper lip 4-lobed, the lower narrow and entire. (Sometimes 

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

 CAPRIFOLIUM, DC. 



1. L. hispidula, Dougl. in Bot. Reg. 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 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, Lindl. Bot. Reg. 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. intemipta : 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, Fl. 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. 

 XYLOSTEUM, 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
