6 CHLOROSPERME^. 



Australia in 1856. I now take the earliest opportunity of acknowledging the merit 

 of his package, and trust that he will acquit me of any intentional suppression. 



Should I be favoured with any further donations of specimens from America, I trust 

 that I may be correctly informed of the circumstances under which they were obtained. 

 Justice shall then be fully done to the merits of the collectors. The Alga? of the Pacific 

 coast have as yet been very imperfectly explored, and probably many curious and 

 beautiful species, still unknown to botanists, remain to reward the future exertions of 

 Californian collectors. Possibly, in the collections of those Californian ladies and 

 gentlemen mentioned by Mr. Frye, new species remain undescribed and unrecorded ; 

 and should these remarks meet the eye of any one possessed of such things, and who 

 may wish to see them duly published, I shall be glad to receive and acknowledge all 

 contributions of Algaa if sent to me through Professor Henry or Professor Asa Gray : 

 and the donors may rest assured that all such communications will be faithfully 

 acknowledged.
