95. Elæagnaceæ (p. 448). Flowers mostly diœcious. Calyx-tube becoming berry-like and enclosing the achene. Seed erect, albuminous. Leaves silvery-scurfy, opposite. [*] 4. Ovary inferior, 1-celled, 1--3-ovuled (but 1-seeded); albumen without testa, bearing the embryo in a cavity at the apex; calyx-lobes valvate. 96. Loranthaceæ (p. 449). Parasitic on trees, with jointed stems and opposite leaves. Flowers diœcious. Ovule solitary, erect. Fruit a berry. 97. Santalaceæ (p. 450). Flowers perfect. Ovules 2--4, suspended from the apex of a central placenta. Fruit dry, indehiscent. Leaves alternate. [*] 5. Flowers all unisexual (polygamous in some Urticaceæ and Empetraceæ, apparently perfect in Euphorbia); cells 1--2-ovuled; embryo nearly as long as the albumen or filling the seed; calyx often wanting, corolla-like only in some Euphorbiaceæ and Empetraceæ; stipules often present. [+] 1. Ovary superior, 3-celled (1-celled in Crotonopsis) with 1 or 2 pendulous ovules in each cell; herbs. 98. Euphorbiaceæ (p. 451). Flowers monœcious or diœcious (involucrate and apparently perfect in Euphorbia). Mostly with milky juice, and usually alternate often stipulate leaves. [+] 2. Ovary 1-celled, 1-seeded; trees or shrubs (except some Urticaceæ). [++] Calyx regular, the stamens as many as the lobes and opposite them or fewer; ovary superior. 99. Urticaceæ (p. 461). Flowers monœcious, diœcious, or (in Ulmeæ) perfect. Seeds exalbuminous or nearly so. Inflorescence very various. [++][++] Perianth mostly none; at least the staminate flowers in aments or spikes or dense heads; albumen none. 100. Platanaceæ (p. 466). Trees, with alternate palmately lobed leaves, sheathing stipules, and monœcious flowers in separate globose heads. Ovary superior; fruit a club-shaped nutlet. 101. Juglandaceæ (p. 467). Trees, with alternate pinnate leaves, no stipules, and monœcious flowers, the staminate in aments. Ovary inferior; fruit a nut. 102. Myricaceæ (p. 469). Shrubs, with resinous-dotted leaves, with or without stipules, and monœcious or diœcious flowers, both kinds in short scaly aments. Ovary superior, becoming a small drupe-like nut. [+] 3. Ovary 2--7-celled, with 1 or 2 suspended ovules in each cell, becoming 1-celled and 1-seeded; calyx mostly none or adherent to the ovary; trees or shrubs with simple leaves. 103. Cupuliferæ (p. 470). Flowers monœcious. Fruit a nut surrounded by an involucre, or (in Betuleæ) a small winged or angled naked nutlet in the axils of the scales of an ament. [+] 4. Ovary 1-celled, becoming a 2-valved pod with two parietal or basal placentæ bearing numerous small comose seeds; perianth none. 104. Salicaceæ (p. 480). Diœcious trees or shrubs, with both kinds of flowers in aments, and simple alternate stipulate leaves. [+] 5. Ovary several-celled, becoming a drupe containing 3--9 1-seeded nutlets; seed erect; low shrubby heath-like evergreens.
