Harv. Univ. 10 (1942) 82, we inadvertently included in 
synonymy I7.myrianthum Lindl. [var. ] album “*Rehb.t.”” 
ex Williams. This variety is better referable to the typi- 
‘ally white-flowered J7. verrucosum. 'The flowers of var. 
myrianthum, instead of being ‘‘almost pure white to deep 
ruby-red or purplish red,”’ are apparently only ruby-red 
or purplish red.
