till Florideernes Systematik, published in 1870, Agardh. who at that 

 time had never seen a specimen of P. Californica, added two more 

 species and first described the fruit, from which he decided that the 

 genus belonged to the DumonticB. I have no specimens of P. Woodii 

 or P. Grayana. Of P. Californica I have oidy seen fruiting specimens 

 through the kindness of Prof. Eaton. As the plant should be exam- 

 ined in a living condition, I will not increase our ignorance by saying 

 any thing on the subject. It is evidently destined to wander through 

 different orders before reaching its final resting-place.
