A Phytosociological Classification of the Peruvian Vegetation

Abstract

AbstractThe present work is an update of the syntaxonomic scheme of Peru, with the results obtained to present. We currently recognize 218 phytosociological associations, of which 11 are novelties: Ageratino azangaroensis-Polylepidetum incarum ass. nov., Alchemillo pinnatae-Stipetum hans-meyeri ass. nov., Barnadesio dombeyanae-Polylepidetum racemosae ass. nov., Eclipto prostratae-Echinochloetum crus-pavonis ass. nov., Geoffroeetum decorticantis ass. nov., Junellio arequipensis-Proustietum cuneifoliae ass. nov., Lemnetum aequinoctialis ass. nov., Mutisio cochabambensis-Polylepidetum incarum ass. nov., Poo glaberrimae-Calamagrostietum eminentis ass. nov., Sarcocornietum andinae ass. nov., and Schino mollis-Prosopidetum calderensis ass. nov. These 218 associations belong to 34 phytosociological classes, four of which are described here for the first time: Limoselletea australis cl. nov., Mimulo glabrati-Plantaginetea australis cl. nov., Tillandsietea latifolio-landbeckii cl. nov., Woodsio montevidensis-Cheilanthetea pruinatae cl. nov. In addition, 5 new orders (Alternanthero pungentis-Cynodontetalia dactylonis ord. nov., Coreopsietalia fasciculatae ord. nov., Echinopsio schoenii-Proustetalia cuneifoliae ord. nov., Mimulo glabrati-Plantaginetalia australis ord. nov., Tillandsietalia latifolio-landbeckii ord. nov.), and 7 new alliances (Azollo filiculoidis-Lemnion gibbae all. nov., Ditricho submerse-Isoetion lechleri all. nov., Echinopsio schoenii-Proustion cuneifoliae all. nov., Haageocerion acranthi all. nov., Lepidio chichicarae-Cynodontion dactylonis all. nov., Schoenoplection tatorae all. nov., and Tillandsion purpureo-latifoliae all. nov.) are also described.
