Discussion
Species 2 (2 in the flora).
Chionophila shares morphological similarities with Penstemon, most notably an epistaminal nectary of glandular hairs. Both have a base chromosome number of eight. R. M. Straw (1966) hypothesized that they are sister taxa. Relationships among genera in Cheloneae remain equivocal (A. D. Wolfe et al. 1997, 2002, 2006; S. L. Datwyler and Wolfe 2004). Chionophila is distinguished from Penstemon by a more prominent calyx tube, spikelike racemes, prominently winged seeds, and absence of bracteoles.
Selected References
None.
