The systematic significance of achene micromorphology in Carex retrorsa (Cyperaceae)
Scanning electron microscopy (SEM) was used to examine achene epidermal features of nine Carex species within sections Vesicariae and Lupulinae. Two major epidermal features are recognized in this study: the epidermal layers with one or two primary silicon bodies in each cell and the absence of any primary silicon body. Comparative data of achene morphology using SEM, and evidence compiled from previous investigations, support the placement of Carex retrorsa within section Vesicariae. © 1987 The New York Botanical Garden.
