Answer 1

The sporophyte is an evergreen, delicate herb. Its size varies greatly from species to species i.e., from a few cm. to 20 meters. Plants may be erect or prostrate depending upon the sub-genus. In the sub-genus homoeophyllum the plants are erect e.g., S. rupestris, S. spinulosa etc. and in the sub-genus heterophyllum the plants are prostrate e.g., S. kraussiana, S. lepidophylla etc.
