Abstract: 
Previous classifications within subfam. Tillandsiodeae Harms (Bromeliaceae) are based primarily on characters determined from dried specimens. Floral characters are seldom well preserved in dried material and no associated suites of characters delimiting groups have been described. Some genera and subgenera are currently distinguished by single "key characters." Taxonomically useful suites of floral traits ascertainable only from fresh or spirit-preserved flowers of 91 species of Tillandsia L. subgen Tillandsia are used here to circumscribe five preliminary taxonomic groups. Sixteen species of subgen. Allardtia (A. Dietrich) Baker were also examined, and 13 were assigned to three of these groups.
