20A CAPRIFOLIACE^. Lonicera. 



5. LONICERA, Linn. Honeysuckle. Woodbine. 



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

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

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

 mens 5, inserted on the tube of the coroUa. Ovary 2-3-ceUed, 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 occasionaUy sinuate-pinnatifid on vigorous young shoots. 



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

 fra-rance, especiaUy the European Honeysuckles, L. CaprifoUumandL. Etrusca ; the^Amencan 

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

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



L c'lLiosA 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 tivine : flowers sessile m a 

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

 monly connate) leaves, usiially rather large and shoivy : calyx-teeth persistent 

 on the {red or orange) berry : corolla in cdl the Calif ornian sjyecies decidedly 

 bilabiate, the ujyper lip i-lobed, the lower narrow and entire. {Sometimes 

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

 Caprifolium, DC. 

 1. L. hispidula, Dougl. in Bot. Pveg. 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 : — • i i \ 



Yar. Douglasii, the first described form, from Oregon : leaves (i - U mches long) 

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

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

 n. i. 283. Caprifolium hispidulian, Lindl. Bot. Eeg. 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. 



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

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



Yar. 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, Prqc. 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- 



oblouff 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
