Plants -- United States
62. Sapotaceæ (p. 332). Flowers small, 4--5-merous. Style 1. Ovary
few--several-celled; fruit fleshy, bearing a single bony-coated seed.
Shrubs or trees, with milky juice and alternate entire leaves.
[*] 4. Ovary superior or more or less adnate to the calyx,
few--several-celled, the cells 1-ovuled; stamens twice as many as the
corolla-lobes or more; trees or shrubs, with alternate leaves.
63. Ebenaceæ (p. 333). Flowers diœcious or polygamous. Stamens on the
corolla. Ovary superior. Styles distinct. Fruit fleshy, few-seeded.
64. Styracaceæ (p. 333). Flowers perfect. Stamens subhypogynous. Ovary
more or less inferior. Style 1. Fruit dry or nearly so, 1--4-seeded.
[*] 5. Ovary superior, of two carpels (sometimes by division apparently
4-carpellary, sometimes of 3--5 in Polemoniaceæ, Convolvulaceæ, and
Solanaceæ); stamens on the corolla (except in apetalous Oleaceæ),
alternate with its lobes, as many or fewer.
[+] Corolla not scarious and nerveless.
[++] Corolla none, or regular and 4-cleft or -parted, the stamens fewer
than its lobes; style 1; seeds 1--3.
65. Oleaceæ (p. 335). Trees or shrubs, with opposite and pinnate or
simple leaves. Flowers perfect or polygamo-diœcious. Stamens mostly
2, alternate with the usually 2-ovuled carpels.
[++][++] Corolla regular, its lobes 4--5 or rarely more; stamens as
many.
[=] Ovaries 2, becoming follicles; stigmas and sometimes the styles
united; herbs with milky juice, perfect 5-merous flowers, and simple
entire leaves.
66. Apocynaceæ (p. 337). Stamens distinct or the anthers merely
connivent, with ordinary pollen. Style 1.
67. Asclepiadaceæ (p. 338). Stamens monadelphous, the anthers
permanently attached to a large stigmatic body; pollen mostly in waxy
masses. Styles distinct below the stigma.
[=][=] Ovary compound (ovaries two in Dichondra), with 2 or 3 (rarely 4
or 5) cells or placentæ; stamens distinct; mostly herbs.
[a.] Leaves opposite; corolla-lobes 4 or 5 or more.
68. Loganiaceæ (p. 345). Leaves entire, with stipules or a stipular line
joining their bases. Capsule 2-celled, few--many-seeded. Herbs or woody
twiners (our species).
69. Gentianaceæ (p. 346). Glabrous herbs; leaves entire, sessile and
simple (except in Menyanthes). Capsule 1-celled with 2 parietal placentæ
or the whole inner surface ovuliferous, many-seeded.
[b.] Leaves alternate (sometimes opposite in Polemoniaceæ and
Hydrophyllaceæ); corolla-lobes always 5 in our species.
70. Polemoniaceæ (p. 354). Capsule usually 3-celled, loculicidal; seeds
1--many in each cell on the stout placental axis. Style 3-cleft or
-lobed. Leaves opposite or alternate, simple or compound.
71. Hydrophyllaceæ (p. 357). Leaves often lobed or divided, and the
inflorescence frequently scorpioid. Style 2-parted or 2-lobed. Capsule
1-celled, 2-valved with two parietal or introflexed placentæ, or
sometimes 2-celled. Seeds 2 or more on each placenta.
