TYPE: common by waterfall over sandstone, Bonnetia forest, northwestern

 mark 74863. 



The extreme youth of the only collection of Lindmania tillandsioid.es and the 

 extreme age of the material of its only near relative, L. brachyphylla, makes 

 evaluation of the two species very difficult. The difference in the leaf -blades 

 plus the difference in locality makes it seem probable that they are distinct 

 species, but it is difficult to affirm or deny by characters of the inflorescence. 

 Both have dense, few-flowered racemes with relatively long sterile bases and 

 ample floral bracts, but the flowers of L. tillandsioides are too young to indicate 

 if they will become secund and those of L. brachyphylla are too old to show the 

 the complete form of floral bracts and sepals.
