Which is a genus of more species, Dryopteris or Alonsoa?
Dryopteris Dryopteris , 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. 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.
Glossopteris Glossopteris (Ancient Greek: γλώσσα "glossa" , meaning "tongue", because the leaves were tongue-shaped) is the largest and best-known genus of the extinct order of seed ferns known as Glossopteridales (also known as Arberiales or Ottokariales). The genus "Glossopteris" refers only to leaves, within a framework of form genera used in paleobotany. (For likely reproductive organs see Glossopteridaceae.) These are important because they indicate biological identity of these plants that were critical for recognizing former connections between the varied fragments of Gondwana: South America, Africa, India, Australia, New Zealand, and Antarctica.
