CHLOROSPERMEiE. 
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 he 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 Algae 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 Algse if sent to me through Professor Henry or Professor Asa Cray : 
and the donors may rest assured that all such communications will be faithfully 
acknowledged.
