of the ovules. Instead of being suspended from the summit of the 
cells they seemed, in the youngest state, to be fixed to the lower 
part of the cell, and to be somewhat ascending. The plant is not 
described in the Botanical Report of the Expedition, but was laid 
aside for future study and not taken up again until lately. In order 
to obtain the opinion of the highest authority in Euphorbiacese, my 
friend Dr. Gray sent a specimen of the plant to Dr. J. Miiller, of 
Geneva, the author of several works on the Natural Order and of 
the elaborate monograph on the same in the Prodromus of De 
Candolle. His answer is contained in the accompanying extract 
from a letter to Dr. Gray, dated January 7th, 1873. 
“The fragment of the new. Arkansas Phyllanthus is curious as 
“an intermediate form between hanging and ascending ovules. 
“The ovules appear ascending because their micropylar part is 
“more elongated than usual, or the rhapheal part shorter compared 
“with the micropylar (the rhaphe is distinct), but the whole ovule 
“is fixed, in the young state, much nearer the middle than the 
“base. All this does not change the character of the order quoad 
“ direction of micropyle and radicula, but it requires a modification 
“ of the terms upon form and attachment of ovules: Ovules hang- 
“ing and anatropal or laterally fixed and hemianatropal.”
