108. [Hydrocharidaceæ] ([p. 495]). Aquatics, with diœcious or polygamous flowers from a spathe; outer perianth calyx-like, the inner sometimes wanting. Stamens 3–12. Ovary 1-celled with 3 parietal placentæ or 6–9-celled with axile placentæ.
109. [Burmanniaceæ] ([p. 496]). Terrestrial, with scale-like cauline leaves and regular perfect triandrous flowers. Perianth corolla-like.
110. [Orchidaceæ] ([p. 497]). Terrestrial, with very irregular perfect flowers. Stamens and style connate; anthers 1 or 2. Capsule 1-celled; placentæ 3, parietal. Perianth corolla-like.
[+] 2. Seeds albuminous. (Ovary 3-celled and flowers regular in our genera.)
111. [Bromeliaceæ] ([p. 511]). Mostly epiphytes, with dry persistent scurfy leaves. Flowers 6-androus; outer perianth calyx-like.
112. [Hemodoraceæ] ([p. 512]). Fibrous-rooted, with equitant leaves and perfect 3- or 6-androus flowers. Perianth persistent, woolly or scurfy outside. (Ovary sometimes nearly free; leaves flat in Aletris.)
113. [Iridaceæ] ([p. 513]). Root not bulbous; leaves equitant in two ranks. Flowers from a spathe. Stamens 3, opposite the outer lobes of the corolla-like perianth; anthers extrorse.
114. [Amaryllidaceæ] ([p. 515]). Often bulbous-rooted and scapose. Perianth corolla-like. Stamens 6; anthers introrse.
115. [Dioscoreaceæ] ([p. 517]). Climbing, with net-veined leaves. Flowers diœcious, small, 6-androus; perianth calyx-like. Ovules 1 or 2 in each cell.
