CABOMBA (the native name in Guiana). ORD. Nymphæaceæ. SUB. ORD. Cabombeæ. Small and very interesting aquatics. They thrive well in a cistern 1ft. deep, with 2in. of loam in the bottom, for the plants to root in, then filled up with water, and placed in a warm part of the greenhouse during summer, being allowed a rest in a cool part of the stove in winter. Propagation may be effected by root division.

Submerged leaves opposite, stalked, cut into five divisions even to the petiole; segments multifid; floating leaves alternate, on long petioles, peltate, orbicular, entire. Guiana, 1823. SYN. Nectris aquatica.

CACTEÆ. A large order of succulent plants, with remarkable spines clustered on the cylindrical, angular, two-edged, or leafy stems. Flowers very variable, showy or minute, usually solitary, sessile, rarely in fascicles, ephemeral; petals disposed in two or more series, hardly distinguishable from the inner sepals, and sometimes united with them; sepals numerous, united and adnate a great length to the ovarium. Fruit fleshy, one-celled, many-seeded. Well-known genera are Cereus, Melocactus, Mammillaria, Opuntia, Pereskia, and Rhipsalis.
