Figure 4 - Infructescence structure in Tillandsia capillaris complex. a–b Tillandsia capillaris (=Tillandsia capillaris f. incana and Tillandsia capillaris f. hieronymi) a glabrous floral bracts much shorter than the sepals b the ovate-lanceolate sepals are partially fused c–d Tillandsia virescens s.str. (=Tillandsia capillaris f. cordobensis) c pubescent floral bracts equaling the sepals d the acute sepals are much more fused (60-90%) e–f Tillandsia virescens s. l. (=Tillandsia capillaris f. virescens) e pubescent floral bracts equaling the sepals, lacking scapes and violet capsules f the acute sepals are almost totally fused. Abbreviations: s=sepals; b=floral bract, bars=1 mm.
