write the identifying features of dryopteris and funaria
Answers
Funaria is a genus of approximately 210 species of moss. Funaria hygrometrica is the most common species. Funaria hygrometrica is called “cord moss” because of the twisted seta which is very hygroscopic and untwists when moist. The name is derived from the Latin word “funis”, meaning a rope. In funaria root like structures called Rhizoids are present.
Capsules are abundant with the moss surviving as spore when conditions are not suitable.
Moss plant Funaria grows in dense patches or cushions in moist shady and cool places during the rainy seasons. It has a height of 3–5 cm, a radial symmetry with a differentiation of an axis or stem, leaves or phylloids and multicellular colorless branched rhizoids with oblique septa.
These are primitive multicellular, autotrophic, shade loving, amphibious plants. They reproduce by spore formation. They have no vascular system. Root like structures called rhizoids are present. They show alternation of generation i.e. the gametophytic stage alternates with the sporophytic stage.
Dryopteris /draɪˈɒptərɪs/,[1] commonly called wood fern, male fern (referring in particular to Dryopteris filix-mas), or buckler fern, is a genus of about 250 species of ferns with distribution in Eastern Asia, the Americas, Europe, Africa, and the Pacific islands, with the highest species diversity in eastern Asia.[2] Many of the species have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of fronds. The sori are round, with a peltate indusium. The stipes have prominent scales.
Hybridisation is a well-known phenomenon within this group, with many species formed by this method.
