Sansevieria

Sansevieria is a genus of about 70 species of flowering plants, native to Africa, Madagascar and southern Asia. Common names include mother-in-law's tongue, devil's tongue, jinn's tongue, bow string hemp, snake plant and snake tongue. It is often included in the genus Dracaena; in the APG III classification system, both genera are placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It has also been placed in the former family Dracaenaceae.

Etymology

The genus was originally named Sanseverinia by Petagna to honor his patron Pietro Antonio Sanseverino, Count of Chiaromonte (1724-1771), but the name was altered for unknown reasons by Thunberg, possibly influenced by the name of Raimondo di Sangro (1710–1771), prince of San Severo in Italy. Spellings "Sanseveria" and "Sanseviera" are commonly seen as well, the confusion deriving from alternate spellings of the Italian place name.

Characteristics

There is great variation within the genus, and species range from succulent desert plants such as Sansevieria pinguicula to thinner leafed tropical plants such as Sansevieria trifasciata. Plants often form dense clumps from a spreading rhizome or stolons.
