Scrophulariaceae |
| 222 genera, 18 with aquatic species. Annual or
perrenial. Leaves opposite or whorled. Flowers
actinomorphic or zygomorphic, when zogomorphic usually
2-lipped. Sepals tubular with 3-5 lobes. Stamens 4, 2 or
rarely 5, staminodes sometimes present; anthers
2-locular, opening by 1 continuous slit. Ovary superior
of 2 united carpels with horizontal septum; ovules axile;
fruit a capsule; seeds usually numerous with fleshy
endosperm. In this family it is very difficult to draw
the line between true aquatics and plants that may
tolerate short periods of submergence following sudden
rains or floods. The following genera although recorded
as being collected in water have been excluded as I can
find no evidence that they grow or can persist in water: Artanema,
Buchnera, Calceolaria, Conobia, Mecardonia, Micargeria,
Scoparia, Stemodia and Striga. |
