van der Werff and Consiglio 2004). We follow the Angiosperm Phylogeny Group (APG [Angiosperm Phylogeny Group] 2003), thus treating Leguminosae (including CP673451 manufacturer Caesalpinaceae, Mimosaceae and Papilionaceae) and Malvaceae (including Bombacaceae, Sterculiaceae, Tiliaceae and Malvaceae) sensu lato. Buddlejaceae is included in Scrophulariaceae, Cecropiaceae in Urticaceae, Flacourtiaceae in Salicaceae. For nomenclature, we follow the Missouri Botanical Garden’s TROPICOS online database. Results We found 193 Captisol price species reported in both countries,

272 species for Ecuador (79 reported only for Ecuador) and 234 species for Peru (41 reported only for Peru). The most species-rich family was Leguminosae with 70 species, followed by Malvaceae (19 species) and Boraginaceae, Cactaceae and Moraceae (12 species each). The most genera-rich families were Leguminosae and Malvaceae (with 34 and 15 genera, respectively), followed by Verbenaceae, Euphorbiaceae (both with 8 genera) and Cactaceae (7 genera) (Table 1). Most families

were represented by few species. The 11 most speciose families (Table 1) accounted for 182 species Nepicastat price (58% of the total) and 92 genera (51% of the total). Thirteen families were included having only one woody species present in SDFs in the region: Acanthaceae, Agavaceae, Bixaceae, Burseraceae, Celestraceae, Combretaceae, Ebenaceae, Monimiaceae, Olacaceae, Oleaceae, Opiliaceae, Polemoniaceae, Rosaceae.

Most of them are typical for SDF vegetation, although some are also found in other vegetation types. Leguminosae is the family with most endemics (15 species), followed by Cactaceae (7 species) and Malvaceae (6 species). Thirty-four species have been assigned an IUCN red list category, 31 of which are also endemic to Ecuador, Peru or the Equatorial Pacific region (Appendix 1). The other three species (e.g., Cedrela odorata) are also very well represented in neotropical SDF, but have a wider geographical distribution.
