Taxonomic significance of microhair morphology in the genus Eragrostis Beauv. (Poaceae)

Strong correlations are demonstrated in 74 species of Eragrostis, involving microhair morphology ('chloridoid' and 'panicoid') types, PCR (photosynthetic carbon reduction) sheath anatomy, and modes of spikelet disarticulation. The observations seem significant in relation to infr...

Description
Summary:Strong correlations are demonstrated in 74 species of Eragrostis, involving microhair morphology ('chloridoid' and 'panicoid') types, PCR (photosynthetic carbon reduction) sheath anatomy, and modes of spikelet disarticulation. The observations seem significant in relation to infrageneric classification.
