Part 75 (1/2)

_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 Linnaea, doubled in Adoxa) _the lobes of the tubular or rotate corolla, and inserted on its tube._--Fruit a berry, drupe, or pod, 1--several-seeded. Seeds anatropous, with small embryo in fleshy alb.u.men.

Tribe I. SAMBUCEae. 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 cl.u.s.ter.

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. LONICEREae. 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 corolla. 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 perennial herb with scaly rootstock and ternately divided leaves, the cauline a single pair. An anomalous genus. (From ?d????, obscure or insignificant.)

1. A. Moschatellina, L. Smooth, musk-scented; radical leaves 1--3-ternate, the cauline 3-cleft or 3-parted; leaflets obovate, 3-cleft; flowers several in a close cl.u.s.ter on a slender peduncle, greenish or yellowish.--N. Iowa, Wisc., and Minn., and northward. (Eu., Asia.)

2. SAMBuCUS, Tourn. ELDER.

Calyx-lobes minute or obsolete. Corolla open urn-shaped, with a broadly spreading 5-cleft limb. Stamens 5. Stigmas 3. Fruit a berry-like juicy drupe, containing 3 small seed-like nutlets.--Shrubby plants, with a rank smell when bruised, pinnate leaves, serrate-pointed leaflets, and numerous small and white flowers in compound cymes. (The Latin name, perhaps from sa???, an ancient musical instrument.)

1. S. Canadensis, L. (COMMON ELDER.) Stems scarcely woody (5--10 high); _leaflets 5--11, oblong_, mostly smooth, the lower often 3-parted; _cymes flat; fruit black-purple_.--Rich soil, in open places, throughout our range, and south and west. June, July.--Pith white.

2. S. racemsa, L. (RED-BERRIED ELDER.) Stems woody (2--12 high), the bark warty; _leaflets 5--7, ovate-lanceolate, downy underneath; cymes panicled, convex or pyramidal; fruit bright red_ (rarely white). (S.

p.u.b.ens, _Michx._)--Rocky woods, N. Scotia to Ga., and westward across the continent. May; the fruit ripening in June.--Pith brown. Both species occur with the leaflets divided into 3--5 linear-lanceolate 2--3-cleft or laciniate segments.

3. VIBuRNUM, L. ARROW-WOOD. LAURESTINUS.
