104 THE BOTANISTS OF PHILADELPHIA. 



to a hitherto undescribed plant that belongs to the Syn- 

 genesia, which he names the Marshallia. Give my best 

 respects to your uncle, Mr. Hu'mphry Marshall, and believe 

 me, with great esteem, sir, 



" Your humble servant, 



" Henry Muhlenberg." 



In the collection of the Marshall papers in the pos- 

 session of Gilbert Cope, I have found the following copy of 

 the reply to this note in the handwriting of Dr. Marshall : 



" West Bradford, April 13, 1792. 

 " Reverend Sir : — I have just received yours of the 9th 

 instant, and am much pleased to hear of the arrival of the 

 Genera Plantarum. I am very sensible of the honor done 

 me, through your request, by Dr. Schreber, and think 

 myself but too undeserving. I shall be pleased in your 

 calling on your intended journey, and hope you will 

 consider my uncle's house as a welcome stage. I am, with 

 all due respect, 



" Your much obliged friend, 



"Moses Marshall." 



I have given this correspondence complete, as, in the 

 list of plants named for Chester County botanists, prepared 

 by Dr. Darlington in 1857, we find the following statement : 



" The genus Marshallia was so named in 1791 by Dr. 

 Schreber, in honor of Humphry Marshall, of West Brad- 

 ford Township." 



In another place Dr. Darlington says that the plant 

 was named for Humphry Marshall and his nephew, j^et the 

 above correspondence indicates that Moses Marshall alone 

 was recognized by Schreber and Muhlenberg in the 

 transaction.
