bose, ending the branches. Fl. yellow.—Name in honour of David Gorter, a Dutch 
botanist and author of a Flora Belgica.

_Very similar to G. personata, but with longer rays, and much more copiously 
ciliate, usually broader inv. scales, . has shorter rays, but longer than in @. per

4. G. corymbosa (DC.! Lc. 501); stem erect, very sparsely setose,
