San Antonio, June 9» l8?8 



Dr. George Engelmann, St. Louis, Mo. 



Your esteemed letter of 5~2*f has been received and I only regret that 

 it did not arrive sooner, because then perhaps I could have done more for 

 you, while now the blooming of many cacti is passed. At the same time I 

 would like to ask you if you are interested in receiving flowers of them, 

 in which case I will gladly send you dried ones, or perhaps still better, 

 fresh ones packed in moist sand. 



The two radiosa and pur i IIa have bloomed profusely and, even though 

 the flower closes in the evening, it opens again in the morning, and indeed 

 some individual ones in 3-^ days again. Have yours bloomed? Likewise 

 M. micromeris blooms, fleshy and 2 lines long, yesterday a seed appeared, 

 that is 2 1/2 months after blooming. Pancispinus bloomed very beautifully 

 and one flower was open 7 days, if it draws together somewhat at night, it 

 never closes completely. I also have another one with almost the same 

 flower, a somewhat lighter and radiant red and open also *f~7 days, the form 

 of the plant more echino-like, more round, Short, dense and one upon another 

 growing sprouts. Eight ribs, 2 1/2-3A 1 thick and 3 f high, füll round 

 Areola central thorns 7 even 8 inches long, dark brown 6-8 rad. fernlike 

 5-6 lin. long. Enneacantus has bloomed very beautifully, of this I also 

 have a very similar one and probably the same to which you yourself call 

 attention of the dissimilarity, in your Gactaceae of the Boundary . On the 

 latter I have some stems up to 10" high by 3" thick and central thorn up
