ce^tairr, that you rave ne the true species - -. I warten, to collect" 

 seeds of ny Opuntae; unf ortuna tely, those berries, which did not fall 

 off with the flower, were ertirely enpty and ^thout seeds.. 



Man* . Gooderi rhlV ( not pcoodorichii) fron the Island Cerros 

 (not corros) ' Mr. Seeman has also found on the nainland. It has only 

 one hook-like spine; and with other species it is possi ble, that 

 there are nore of it. The travels of Dr. LeConte, Perry, Eraory and 

 others, will lead to new diseoveries # , and fron the areas as New- Call - 



fornia, New Mexico,. , will nake one of the strängest.. 



In the Organization of the caetjr I have been. anxious, to leave rooer 

 for the future» , and for future corrections. You find, that I included 

 too nany of the species, and that is quite likely; but not concerning 



Op. ^na , Fici I ndj a , l^ucaphylla a^.d pseudo-tuna ». The 2 first ones 



are very ancient species, which' the Dillon and Miller knew already,,. 

 and the two last ones are e^tirely dif f e^ent fron then.. These species 

 are all at hone in the Antilles or southern Araerica^ and eertainly d.o 

 not grow in your areas. My Echoe, calif o^ricus nay possiblv not cone 

 fron California ; Kr. von Monville ( or Monwitte ? E.D. ) called it that 

 It reraains, though, a good speci es, di stingui shed through its colored 

 spines.. May God help, that the seeds of Cer. gigantens gerninate ! I 

 am very anxious, to know a species living so far North, which surpas- 

 ses by its size the southern merabers of the sane genus. 



Will it be possible to use the outer form of seed-corns for a 

 Classification, of cacti ?' It seens very dubious to ne.- We know only 

 3 forms, which perralt dif f erentiationj That of a thimble (cylindrical,, 

 flat on " the bottom, round on top) a sonewhat ball- shaped and one 

 sonewhat lense or lentil-shaped . . The first is part of the Melocateae,. 

 and the last is found mostly with the Onuntiae and Peiresciae ; and 

 the ball-shaped is the one, which appears to nost. The Cotyledons 

 have been used , and c one erring the analysis of the renaining parts
