Abstract
The nectar sugar compositions of 50 species of Erica have been analyse d by HPLC. A marked dichotomy in nectar sugars was evident within the genus. Of the ornithophilous species analysed, 29 had sucrose-dominant nectars and eight had hexose-dominant nectars. Both nectar types occu rred within the artificial sections into which the genus is currently divided. Our results contradict the idea that flowers pollinated by pa sserine birds produce hexose-dominant nectars.
