Taxonomía del grupo Atríplex pentandra (Chenopodiaceae)

Taxonomía del grupo Atríplex pentandra (Chenopodiaceae)

AS A RESULT OF A MORPHOLOGICAL STUDY OF MORE THAN 2000 SPECIMENS OF THE ATRIPLEX PETANDRA GROUP (FIDE HALL Y CLEMENTS, 1923) FROM 32 HERBARIA, A TOTAL OF 16 PECIES, AND 1 SUBSPECIES ARE RECOGNIZED SUGGESTING THEIR INCLUSION WITHIN THE OBIONE SECTION. DESCRIPTIONS, HABITAT INFORMATION, DISTRIBUTION MAPS AND A KEY TO THE SPECIES, ARE PRESENTED. CHROMOSOME NUMBERS FOR A. LINIFOLIA AND A. PUEBLENSIS ARE REPORTED FOR THE FIRST TIME, SUPPORTING THE IDEA THAT POLYPLOIDY IS NOT A VERY IMPORTANT PROCESS IN THE EVOLUTION OF THE GROUP. VARIOUS POLLEN GRAIN CHRACTERS WERE STUDIED, WHICH TURNED OUT TO BE OF NO TAXONOMICAL IMPORTANCE.

COMO RESULTADO DE LA REVISIÓN MORFOLÓGICA DE MAS DE 2000 EJEMPLARES DEL GRUPO ATRIPLEX PENTANDRA (FIDE HALL Y CLEMENTS, 1923) DEPOSITADOS EN 32 HERBARIOS, SE RECONOCEN 16 ESPECIES Y UNA SUBESPECIE, SUGIRIÉNDOSE SU CLASIFICACIÓN EN LA SECCIÓN OBIONE. SE PROPORCIONAN DESCRIPCIONES, ILUSTRACIONES, INFORMACIÓN SOBRE EL HÁBITAT , MAPAS DE DISTRIBUCIÓN Y UNA CLAVE PARA LAS ESPECIES. SE APORTA POR PRIMERA VEZ EL NUMERO CROMOSÓMICO DE A. LINIFOLIA Y A. PUEBLENSIS QUE RESPALDA LA IDEA DEL POBRE EFECTO DE LA POLIPLOIDIA EN LA EVOLUCIÓN DEL GRUPO. SE ESTUDIARON VARIOS CARACTERES POLÍNICOS DE CINCO ESPECIES QUE RESULTARON SER DE POCO VALOR TAXONÓMICO.
