R. A. Rolfe, in his monograph of Vanilla, referred to 
V’. Pfaviana as being known to him only from the origi- 
nal description. He depended on the suggestion made 
by Reichenbach that the flowers are terminal in the type

by Skutch indicate that the flowers are both terminal and 
lateral; completely opened flowers and buds being pres- 
ent simultaneously on the elongated, leafy stems.
