This paper describes and illustrates three new taxa of Fuchsia from Central America and Mexico. Fuchsia paniculata subsp. mixensis P. E. Berry & Breedlove is newly described in section Schufia; it is from a small area in central Oaxaca, Mexico, that is a geographical transition area between F arborescens and F paniculata. The new subspecies is distinguished by its large pubescent leaves and flowers. Because it has both hermaphrodite and female individuals, it is placed with the gynodioecious F paniculata rather than the exclusively hermaphrodite F arborescens. In section Encliandra, Fuchsia encliandra subsp. microphylloides P. E. Berry & Breedlove is newly described from material that was previously included in F. encliandra subsp. encliandra, but differs in its more divaricating branching pattern and more serrulate leaves. Fuchsia microphylla subsp. chiapensis (Brandegee) P. E. Berry & Breedlove, stat. nov., is created to recognize populations that were most recently treated as part of F microphylla subsp. aprica. This taxon differs from subspecies aprica in its larger leaves, more pubescent stems and leaves, and lower elevational range. Since the latest treatments of the Mexican and Central American species of Fuchsia (Breedlove, 1969; Breedlove et al., 1982), additional field and herbarium studies have led us to recognize one new taxon in section Schufia and two additional taxa in section Encliandra, all of which are described and illustrated below. Both of these sections have members that exhibit sexual dimorphism, a trait which has evolved probably independently in several other sections of the genus. We follow the precedent of Breedlove (1969) in recognizing the new taxa at the subspecific level, implying that they have sufficient morphological, ecological, and/or geographical differences to distinguish them from other populations of the same species. Fuchsia paniculata Lindley subsp. mixensis P. E. Berry & Breedlove, subsp. nov. TYPE: Mexico. Oaxaca: 35 km N of Ayutla along road from Mitla to Choapam, N slope of Cerro Zempoaltepetl, 2470 m, 17 Apr. 1988, (hermaphrodite), Breedlove & Bartholomew 66841 (holotype, CAS). Figure 1. A Fuchsia paniculata Lindley subsp. paniculata foliis ramulisque pubescentibus, nervis secundariis 14-18-jugatis, tubo florali sepalisque roseis differt; florum hermaphroditorum magnitudine formaeque F arborescenti Sims similis. Erect shrub 2.5-4 m tall, gynodioecious; branchlets ascending, 5-30 cm long, finely pubescent with hairs 0.2-0.4 mm long. Leaves opposite, membranous, the blade elliptic, 11-25 cm long, 4-10 cm wide, puberulent on the lower surface along the veins, becoming glabrescent on the upper surface but short hairs often present along the veins, secondary veins 14-18 on either side of the midvein, apex acute to subacuminate, base acute to attenuate, margin gland-denticulate; petiole 10-25 mm long, puberulent; stipules narrowly triangular, dark NovoN 6: 135-141. 1996.
