216 CAPRIFOLIACE^E. (HONEYSUCKLE FAMILY.) 



DIVISION II. GAMOPETALOUS DICOTYLEDONOUS PLANTS. 



Floral envelopes consisting of both calyx and corolla, the latter 

 composed of more or less united petals, that is, gamopetalous.* 



ORDER 51. CAPRIFOLIACEJE. (HONEYSUCKLE FAMILY.) 



Shrubs, or rarely herbs, with opposite leaves, no (genuine) stipules, the 

 calyx-tube coherent with the 2-5-celled ovary, the stamens as many as (one 

 fewer in Linna^a, doubled in Adoxa) the lobes of the tuiiular or rotate 

 corolla, and inserted on its tube. Fruit a berry, drupe, or pod, 1 - several- 

 seeded. Seeds anatropous, with small embryo in fleshy albumen. 



Tribe I. SAMBUCE^E. Corolla wheel-shaped or urn-shaped, regular, deeply 5-lobed. 

 Stigmas 3-5, sessile or nearly so. Inflorescence terminal and cymose. 



* Dwarf herb, with stamens doubled and flowers in a capitate cluster. 



1. Adoxa. Fruit a dry greenish drupe, with 3-5 cartilaginous nutlets. Cauline leaves a 



single pair and ternate. 

 * * Shrubs, with stamens as many as corolla-lobes and flowers in broad compound cymes. 



2. Sambucus. Fruit berry-like, containing three small seed-like nutlets. Leaves pinnate. 



3. Viburnum. Fruit a 1-celled 1-seeded drupe, with a compressed stone. Leaves simple. 



Tribe II. LONICERE^E. Corolla tubular, often irregular, sometimes 2-lipped. Style 

 slender ; stigma capitate. 



* Herbs, with axillary flowers. 



4. Triosteum. Stamens 5. Corolla gibbous at the base. Fruit a 3 celled drupe. Erect ; 



flowers sessile. 



5. Linnaea. Stamens 4, one fewer than the lobes of the corolla. Fruit dry, 3-celled, but 



only 1-seeded. Creeping, with long-pedunculate twin flowers. 



* * Erect or climbing shrubs, with scaly winter-buds. 



6. Symphoricarpos. Stamens 4 or 5, as many as the lobes of the bell-shaped regular 



corolla. Berry 4-celled, but only 2-seeded ; two of the cells sterile. 



7. Lonicera. Stamens 5, as many as the lobes of the tubular and more or less irregular 



con ilia. Berry several-seeded ; all the 2 or 3 cells fertile. 



8. Diervilla. Stamens 5. Corolla funnel-form, nearly regular. Pod 2-celled, 2-valved, 



many-seeded, slender. 



1. ADOXA, L. MOSCHATEL. 



Calyx-tube reaching not quite to the summit of the 3 - 5-celled ovary ; limb 

 of 3 or more teeth. Corolla wheel-shaped, 4 - 6-cleft, bearing at each sinus a 

 pair of separate or partly united stamens with 1-celled anthers. Style 3-5- 

 parted. Dry drupe greenish, with 3-5 cartilaginous nutlets. A dwarf per- 

 ennial herb with scaly rootstock and ternately divided leaves, the cauline a 

 single pair. An anomalous genus. (From &8oos, obscure or insignificant.) 



* In certain families, as in Ericaceae, ete., the petals in some genera are nearly or unite 

 separate. In Composite and some others, the calyx is mostly reduced to a pappus, or a mere 

 border, or even to nothing more than a covering of the surface of the ovary. The student 

 might look for these in the first or the third division ; but the artificial analysis prefixed to 

 the volume provides for such anomalies, and will lead him to the proper order.
