Exalbuminous Monocotyledons are either hydrophytes or strongly hygrophilous plants and have often peculiar features in germination.
Such terms as hydrophytes, xerophytes, and halophytes had been used by plant geographers before Warmings time e.g., by Schouw;4 and the terms evidently supply a want felt by botanists as they have come into general use.
Hydroplzytes and hemi-hydrophytes (aquatic plants).Of marine hydrophytes, there are, in this country, only the grass-wracks (Zostera marina and Z.
Which characterize many hydrophytes and hemi-hydrophytes.
One of the best known classifications on these lines is that by Warming.1 Warming recognized and defined four ecological classes as follows: Hydrophytes.These live in a watery or wet substratum, with at least 80% of water.
The criticisms were directed chiefly to the inclusion of sand dune plants among halophytes, to the exclusion of halophytes from xerophytes, to the inclusion of bog xerophytes among hydrophytes, to the inclusion of all conifers among xerophytes and of all deciduous trees among mesophytes, and to the group of mesophytes in general.
