# To me very agreable letter of July 5 receivedf through the 

 kind arrangement of your mister brother, and I must adralre the speed, 

 by which the letters negotiate the long jonrney. - It is for botlt of 

 us a misfortune, that so few resources- are available to you f and that 

 I an not really capable to aqua Int you with the Status of our know - 

 ledge.. The books, which your nister brother has sent you, are the 

 only ones, which treat cacti exclusively; descriptions of raany new 

 species- are to be found dispersed in Garden news and in other gar - 

 den publications,, which would be dif f icultt to obtain and expensive. 

 Farster, though, has collected all ! , and his handbook is useful in 

 that relatiom- However, he coraported everything with not enougtt cri- 

 tique, and I f for my part, can. not agree with his Geraan dias-roses.. 

 The Berliner Allgemeine Garten Zeitung (Berlin general fraräen news) 

 contains nany good descriptions; ^equally so other botanicaV papers 

 and Journals-; I do not posess them all nyself, and, thus, your well- 

 born will have to make do with those sent you, - I an working orr 

 a new, much more complete and numerous index of my cactus collea - 

 tion, which will also contain descriptions; but for sone time (verb. 

 "year and day f \E.D.) it will not be published ! As much as I shall 

 be able, you will be kept au courantfc. 



The seeds sent to me, have been sown caref ully. . Your EcYr.. 

 Wislizenii is new and not described. . The nane is xooö and shall re- 

 maim . There exist already, as you will see, a M. uncinata , a kagata,, 

 anucistrata , and. all these narae assignments have been takeru. - 

 I do not stand in any direct connection with Mr. Potts; I did how- 

 ever receive several species which cane fron himr*. He is a studious 

 a^d successful collector. Unf ortunately, the war has delayed his 

 last shipments, and recently one perished in Vera Cruz..
