Are Selago and Sobralia both genus of plant?
Sobralia Sobralia is a genus of about 125 orchids (family Orchidaceae) and one of the two genera of the subtribe Sobraliinae (the other is "Elleanthus").
Isoetopsida The Isoetopsida is a class of Lycopodiophyta. All extant species belong to the genus "Selaginella" in the order Selaginellales or to the genus "Isoetes" in the order Isoetales. In the past, members of this group sometimes have been placed in the classes Isoetopsida, Selaginellopsida, or Lycopodiopsida. There are c. 700 species of "Selaginella" and 140-150 species of "Isoetes", with a cosmopolitan distribution, but often scarce to rare. Some botanists split "Isoetes" by separating two South American species into the genus "Stylites".
