While on this subject let me ask whuat is to be done with those 
orders which Dr. Gray considered too hard for beginners, hia I to con- 
tinue the omission of the Umbelliferae ,Gramineae and Cyperaceae ,? And., 
must the Asters and Solidagos be sent to limbo again ? If these plants 
cannot have the full descriptions inserted ---i.e.as full as of the 
others----vrould it not be well to insert them in key form at least ? 
In going over the Ranuncs I noted on or tv/o errata in the Manual 
memoranda of which I enclose. 
I should esteem it a favor receive your opinion on the 
various points above as soon as possible, as I do not want to work on 
an erroneous plan longer than is necessary. 
Very sincerely yours,
