480 FARWELL: Epitrions oF Emory’s REPORT 
pagination is from 179 to 211, the figures appearing in the middle 
at the top of each page, and therefore is probably a second issue 
of edition 3 described by Mr. Coville and is Doc. No. 7; it 
differs from this however, in that the plates are those of C. B. 
Graham of Washington, D. C., and plate VI is labeled Baileya 
multiflora instead of B. multiradiata. It includes Convolvulus 
Nuttallii and Alternanthera? (Endotheca) lanuginosa, which are not 
in Doc. No. 41. Cereus gigantens of the latter becomes C. 
giganteus in the former; E. |Eriogonum| Aberteanum n. sp. 
becomes EF. Abertianum n. sp.; and Stillengia spinulosa n. sp. 
becomes Stillingia spinulosa n. sp. Also the concluding part of 
Dr. Engelmann’s Report, matter pertaining to No. 15 and Cereus 
giganteus, is entirely rewritten. Prof. Torrey’s report occupies 
pages 179-206; p. 207 is occupied by an explanation of plates; 
and on pages 208-211 appears Dr. Engelmann’s report. 
It would, therefore, appear that there are five editions of 
Lieut. Emory’s Report, all of which probably were published in 
1848: two of Ex. Doc. No. 41, one without a description of Zinnia 
grandiflora and one with it; three of Ex. Doc. No. 7, one with 
pagination the same as that of No. 41 and two with different 
pagination; of the latter, one has the plates of E. Weber & Co. 
and one has the plates of C. B. Graham; and all three differ from 
the second edition of No. 41 in including Convoloulus Nuttallii 
and Alternanthera lanuginosa.
