From a nomenclatural standpoint, the correct name of this 

 taxon is Sievia Rehaudiana (Bertoni) Bertoni (1905), not S. 

 Rehaudiana (Bertoni) Hemsley (1906), for reasons of priority. 



Stevia rhombifolia HBK., Nov. Gen. Sp. PI. 4: 1 12. 1818. 



According to Grashoff (1972), the Latin binomial Stevia 

 rhonihifolia as applied to the North American specimens is very 

 ambiguous and confusing, and refers to three distinct taxa: S. 

 joruUensis HBK., S. ovata Willd. and S. trijlora DC, However, 

 its correct identity concerning the South American specimens is 

 yet to be elucidated. In the present paper, ethnobotanical infor- 

 mation associated with this Latin binomial is found under S, 

 ovata, S. nepetifolia and under Stevia species (Molinillo and 

 Salvia). 



Stevia salicifolia Cav., Icon. Descr. PL 4: 32. 1797. 



This species, whose distribution range extends from Mexico 

 to southern United States (New Mexico), is known under vari- 

 ous common names. The names used in Mexico are llierha del 

 j/>^^ (Hidalgo), Hierha de la mula (Guan'djUiiio), Zazal {Siwdloa) 

 and Zazale de olor (Martinez, 1979), and Verba de la njula (von 

 Reis Altschul, 1973). In addition, in the States of Michoacan 

 and Mexico, it is known as La envidia, Verba de la mula and 

 Zazai Small bundles of the dried aerial parts of 5". salicifolia are 

 offered for sale in the Juarez market of Toluca under the name 

 of Zazai where vendors advise that a water decoction or an 

 alcoholic infusion may be used as a rub for rheumatism (Soe- 

 jarto et al., 1983), whereas in the region of Morelia (Michoacan) 

 the plant is used for the same purpose, but under the name of 

 Verba de la mula. 



Under the name of Stevia stenophylla A. Gray, Martinez 

 (1979) reported that this plant is called Hierba de la Santa Rita 

 in the State of San Luis Potosi, Mexico. Grashoff (1972) consid- 

 ered this Latin binomial to be synonymous with S, salicifolia 

 Cav.
