Abstract
The 13C 12C isotope ratios and the leaf anatomy of 18 species and varieties of Euphorbia native to the Hawaian Islands indicated that all possess C4 photosynthesis. These species range from small prostrate coastal strand shrubs to shrubs and trees in rainforest and bog habitats. The results show that C4 photosynthesis occurs in plants from a much wider range of habitats and life-forms than has been previously reported.
