Micromorphology and structure in fruits of Bulbostylis (Cyperaceae) and their systematic value in Southern America species.

Micromorphology and structure in fruits of Bulbostylis (Cyperaceae) and their systematic value in Southern America species. The genus Bulbostylis Kunth includes about 150 species that inhabit tropical and subtropical areas worldwide. In Bulbostylis, as in other kinds of sedges, the exomorphology of...

Micromorphology and structure in fruits of Bulbostylis (Cyperaceae) and their systematic value in Southern America species. The genus Bulbostylis Kunth includes about 150 species that inhabit tropical and subtropical areas worldwide. In Bulbostylis, as in other kinds of sedges, the exomorphology of fruits is one of the steadiest characters for infrageneric classification. This research was focusedon evaluating achene micromorphology in twenty Bulbostylis species of Southern America (Argentina, Chile, Paraguay, Uruguay and Paraná, Santa Catarina and Rio Grande do Sul in Brazil). Based on studies with optical and scanning electron microscopy, several groups are proposed, considering the micromorphology of the achenes and presence and type of silicophytoliths. Chemical microanalysis offruits with EDX/MEB was also performed. The description system based on exomorphological characters, applicable to fruits and seeds, is updated. El género Bulbostylis Kunth incluye aproximadamente 150 especies que habitan zonas tropicales y subtropicales en todo el mundo. En Bulbostylis, al igual que en otros géneros de Ciperáceas, la exomorfología de los frutos es uno de los caracteres más estables para la clasificación infragenérica. En este trabajo se dan a conocer la micromorfología y estructura de los frutos de Bulbostylis para veinte especies de América Austral, representadas en Argentina, Brasil (Paraná, Santa Catarina y Rio Grande do Sul), Chile, Paraguay y Uruguay. En base a estudios con microscopía óptica y electrónica de barrido se proponen agrupamientos, teniendo en cuenta la micromorfología de los aquenios así como la presencia y tipo de silicofitolitos. También se realizan microanálisis químicos de los frutos con EDX/ MEB. Se actualiza el sistema de descripción basado en caracteres exomorfológicos, aplicable a frutosy semillas.
