 which varies from dark red to light yellow and green. The most 

 distinct of these varieties has vellow anthers and vellow fruit often 

 with a reddish cheek. This has sometimes been considered a 

 species, but individuals occur on which flowers with rose-colored and 

 with yellow anthers, and with red and yellow fruits, may occasionally 

 be found. The yellow fruited form is
