Dr. Smith states: ‘‘In 
my treatment of the spe- 
cies of Vriesia with a sim- 
ple secund-flowered in- 
florescence in ‘‘ Lilloa’’ 
VI, 888 (1941), Vriesia 
socialis would run down 
to the vicinity of V’.bras- 
sicoides and V’. Platzman- 
ni, both of them native 
of southeastern Brazil 
over two thousand miles 
distant. Vriesia socialis 
has much longer and narrower sepals and both its sepals 
and floral bracts are much thinner than in either Brazil- 
ian species. ”’
