Discussion

E. P. Killip (1938) and W. C. Martin and C. R. Hutchins (1980) incorrectly indicated that Passiflora tenuiloba is native to New Mexico. This is based upon the misinterpretation of confusing labels on old specimens (see D. H. Goldman 2004).

Passiflora tenuiloba has the most variable leaves of any species in the genus. They vary considerably in texture, color, indument, lobe length and number, and petiole-gland size and shape, not only between populations but also within individual plants.
