The smooth variety, of which we have only a full-grown leaf and 

 mature fruit, requires farther investigation ; but it will probably prove 

 to be only a form of Gaudichaud's Q. petaloidea. I am unable to com- 

 pare the species with the G. bracteata, from Juan Fernandez.

Various forms were collected, both in flower and in fruit, either 

 hairy or almost glabrous ; the scapes varying from 3 lines to as many
