    Type. Mexico. Me´xico: Dist. Temascaltepec, Tejupilco, 1340 m, 30 Sep 1932, Hinton 1935 (holotype NY!; isotype GH!)

    Ab Anemia jaliscana Maxon var. jaliscana pinnis subintegris pinnisque apicalibus late cuneatis diversa. (L, integer, entire,+ folium, leaf, alluding to the pinna margins being more nearly entire than those of the type variety.).

    Hinton 8221 (ARIZ) with malformed spores is mixed with A. hirsuta and is probably the hybrid between that and var. integrifolia, thus representing a counterpart to A. recognita, the sometimes fertile hybrid between A. hirsuta and A. jaliscana var. jaliscana. The range of var. integrifolia overlaps that of var. jaliscana in western Guerrero. Anemia jaliscana is perhaps the most difficult species of Anemia to distinguish in Mexico. The pinnae are somewhat trapezoidal in the most distinctive form, but vary to more elliptic or suborbicular. Occasionally, the proximal pinnae are slightly incised. The pinna margins range from entire to finely denticulate, even on the same plant; pinnae from sterile fronds tend to be more nearly entire than those from fertile ones. When pinna margins are incised, A. jaliscana may look more like A. hirsuta, with which it frequently hybridizes to form A. recondita. Hybrids are often mistaken for A. hirsuta or abnormal A. jaliscana. In fact, one of the NY isotype sheets of A. jaliscana has one plant of A. jaliscana and two of A. recondita. The two species (A. hirsuta and A. jaliscana) apparently share a common ancestor since there is regular pairing of approximately one genome (n=ca. 38II + 114I). In the northern part of its range, especially in Sinaloa, plants of A. jaliscana may look much like A. affinis in having larger, more denticulate pinnae, more broadly oblong than in plants farther south. However, A. affinis can generally be distinguished by the pinnae being suborbicular and glabrous beneath, and being tetraploid (vs. hexaploid).
