 calyx glandular-puberulent, a little hispidulous on the nerves, tubular- 

 campanulate, in anthesis 1 to 1.3 cm. long ; the tube twice exceeding

 Morales, 1876 (Schaffner, no. 661) ; without locality, alt. 1,850 to 2,460

 Mexico, though with larger thinner leaves, may be an extreme form. 

 This species, as well as S. microphylla, is sold in the market of San Luis 

 Potosi as a Mirto, decoction from them being used to allay fever, head- 

 aches, and nervous irritations.

 racemes becoming 1 to 1.5 dm. long; verticels mostly 4-flowered, all
