FIGURE 5 in New genera and a new species in the "Cryptanthoid Complex" (Bromeliaceae: Bromelioideae) based on the morphology of recently discovered species, seed anatomy, and improvements in molecular phylogeny

FIGURE 5. Seed coat anatomy of Cryptanthus and Siqueiranthus. A. seed in median cross section. B–G. seed coat in median crosssection, in the antiraphe region. A–B. S. cinereus (Leme 9785). C. C. pickelii (Leme 9665). D. C. colnagoi (Leme 9154). E. C. aff. burlemarxii (Leme 9487). F. C. aff. beuckeri (Leme 3891). G. C. bahianus (Leme 9616). Arrow = vascular bundle. en = endosperm. r = raphe. sc = seed coat. The numbers indicate the different layers of the seed coat. 1 = endotegmen (with discontinuous elements of mesotegmen). 1' = mesotegmen. 2 = exotegmen. 3 = endotesta. 3' = mesotesta. 4 = exotesta. Bars: A = 500 μm. B-G = 50 μm.
