Salvia venulosa is a perennial plant that is native to a very small region of the Western Cordillera in Colombia. It grows at 1500to elevation in deeply shaded wooded gullies. S. venulosa grows less than 1m (03feet) tall, with narrow ovate leaves that are 6to long and 3cm (01inches) wide, and violet on the underside. The flower is an unusual wine-red color.[1]
A 2010 phylogenetic study of Salvia divinorum and 52 other Salvia species in the subgenus Calosphace suggest that S. venulosa is the closest known relative of S. divinorum.[2] Relatively few species (out of the 600 species of Salvia occurring in Mexico and South America) were included in that study. And it is likely that another yet-to-be identified Salvia is actually more closely related to S. divinorum. There is no evidence whatsoever that S. venulosa has any uncommon alkaloids.
