Cheilanthes yavapensis T. Reeves ex Windham
Myriopteris yavapensis is difficult to distinguish from the very similar Myriopteris wootonii. Both
have ciliate scales on the back (abaxial) side, although the cilia are distribute along the entire length
of the scales on Myriopteris yavapensis rather than more near the base as on M. wootonii. The ultimate
segments of M. yavapensis are round or beadlike. The adaxial (top) surface of M. wootonii is glabrous with
only a few cilia showing through from the other side, whereas it is sparsely pubescent in Myriopteris yavapensis. Myriopteris
yavapensis is an apogamous tetraploid-- meaning that it reproduces by asexual budding and has four sets of chromosomes.
