480 Farwell : Editions 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 

 muUifiora instead of B. muUiradiata . 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] Aherteanum n. sp. 

 becomes E. Ahertianum 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 Convolvulus Nuttallii 

 and Alternanthera lanuginosa.
