Notes on Peruvian Tillandsias (2)
Author(s):—W. Rauh
Publication:—Journal of the Bromeliad Society 24(5): 158-176. (1974)
Taxonomy:—Tillandsia calocephala According to L. B. Smith (Phytologia Vol. 21, March, 1971) T. calocephala is synonomous with T. nana. In general, we agree with L. B. Smith, but the southern Peruvian T. calocephala is quite different. It is much larger than the Tarma plant and the "involucrum" beneath the flower head is more distinct. (p.172-173).
