DIVISION II. GAMOPETALOUS: calyx and corolla both present, the latter of united petals (excepting some Ericaceæ, Styracaceæ, and Oleaceæ, Galax, Statice, and Lysimachia). Apetalous flowers occur in Glaux and some Oleaceæ. Stipules present only in Rubiaceæ and Loganiaceæ, or rarely in Caprifoliaceæ. [*] 1. Ovary inferior; stamens borne upon the corolla, alternate with its lobes. [+] Stamens distinct; leaves opposite or whorled; seed albuminous except in Valerianaceæ. 51. Caprifoliaceæ (p. 216). Corolla mostly 5-lobed, regular or irregular, the stamens as many (one fewer in Linnæa, doubled in Adoxa). Ovary 1--several-celled; fruit a berry, drupe, or pod, 1--several-seeded. Shrubs or herbs; leaves opposite, rarely stipular, not turning black in drying. 52. Rubiaceæ (p. 222). Flowers regular, 4--5-merous, the corolla mostly valvate. Ovary 2--4-celled. Herbs or shrubs; leaves simple, entire, opposite with stipules, or verticillate, usually turning black in drying. 53. Valerianaceæ (p. 228). Stamens (1--4) fewer than the lobes of the somewhat irregular corolla. Ovary with two abortive or empty cells and one containing a suspended ovule. Fruit dry and indehiscent. Herbs. 54. Dipsaceæ (p. 229). Flowers mostly 4-merous and with 4 (rarely 2) stamens, involucellate in involucrate heads; corolla-lobes imbricate. Ovary simple, 1-celled, with a suspended ovule. Herbs. [+][+] Anthers connate into a tube. 55. Compositæ (p. 230). Stamens as many as the valvate corolla-lobes. Ovary with a solitary erect ovule, becoming an achene. Albumen none. Calyx-limb reduced to a pappus or none. Flowers in involucrate heads. [*] 2. Ovary inferior (or superior in most Ericaceæ and in Diapensiaceæ); stamens free from the corolla or nearly so (adnate in some Diapensiaceæ), as many as the lobes and alternate with them, or twice as many; leaves alternate (opposite in some Ericaceæ); style 1. [+] Juice milky; capsule 2--5-celled, many-seeded; herbs. 56. Lobeliaceæ (p. 305). Corolla irregular, 5-lobed. Stamens united, at least by the anthers. Capsule 2-celled or with two placentæ. 57. Campanulaceæ (p. 307). Corolla regular, 5-lobed, valvate. Stamens usually distinct. Capsule 2--several-celled. [+][+] Juice not milky nor acrid; capsule 3--10-celled. 58. Ericaceæ (p. 309). Flowers mostly regular, 4--5-merous. Stamens distinct, more usually twice as many as the corolla-lobes or petals. Ovary inferior or superior. Herbs or shrubs. 59. Diapensiaceæ (p. 326). Flowers regular. Stamens 5, on the corolla, or monadelphous with 5 petaloid staminodia. Ovary superior, 3-celled. [*] 3. Ovary superior; stamens as many as the corolla-lobes and opposite them. 60. Plumbaginaceæ (p. 327). Stamens 5, on the base of the petals. Styles 5. Fruit an achene or 1-seeded utricle. Herbs; leaves radical. 61. Primulaceæ (p. 328). Stamens 4--8, perigynous. Style 1. Fruit a capsule with several seeds on a central placenta. Herbs; leaves radical or opposite or alternate.
