| Submerged herbs, with tuberous rhizomes and fibrous roots: Lvs. long-stalked, oblong or linear, sometimes lacking the parenchyma and having a lattice- like character: fl.-characters those of the family (p. 13). —About two dozen species of warm countries, Asian, African and Australian. Krause & Engler, Das Pflanzenreich, hft. 24 (1?06). There are two main species in cult., the aponogeton proper with solid Lvs., and the ouvirandra with open-work Lvs. The former is grown mostly out-of-doors; the latter in warm greenhouses. | | Submerged herbs, with tuberous rhizomes and fibrous roots: Lvs. long-stalked, oblong or linear, sometimes lacking the parenchyma and having a lattice- like character: fl.-characters those of the family (p. 13). —About two dozen species of warm countries, Asian, African and Australian.
