Griffinia alba is described as new from Tapera, Pernambuco, in northeastern
Brazil. It is most similar to the type species for the genus Griffinia, G.
hyacinthina, which is known from the states of Rio de Janeiro and Sao Paul
o in southeastern Brazil. It differs from this species by its cuneate leaf
bases, and more numerous, entirely white flowers with longer pedicels and n
arrower tepals. Griffinia abba is the first white-flowered species to be de
scribed in subgenus Griffinia.
