open beforejbhe two H aa H ; this possibility I would look for if I 



had the opportunity. The flowers rt aa H carry at their base.incli- 



ne d f sideways small bracts H cc»\which are mostly avrils.but which 



occasionally produce in their axis later flowerlng third or 



fourth flowers "bb^ ; these show two more bracts H c, d M at the base, 



which I found steril always; but one could imagine, that they too 



could flower sonetimes. 



I though, I had already said, that I consider my A. falcata 

 striata \ . 



identical with gisfcgfeg, recurva ard stricta^ and Hyrtrix. What is ^our 



opinion ? 



The rotes about Versch^f eltii make ne anxious for further obser- 

 vations.Should the .^ereral opinion, thatjthe exemples of seeds hap- 

 pen to be so dif ferent, possibly be based on a raistake or mix-up of 

 the seeds ? The gardeners and collectors are often negligent.- I, 

 also spoke\in my last (letter) about possible belonging together of 

 Verschaff eltll with scolymus « which Baker believes*. 



What you connaunicate about the teeth is quite Interesting. Too 

 bad, that the development of these plants takes so long. Cnly when 

 they flower can one speak definively about their identitjn* May it 

 be so» 



Of the alraost spineless A. sisalana I sent at some time a good 

 specimen to 'Berlin? if it arrived, I do not know. We have one here 

 with leaves Ii foot long leaves»but it does not forn any stolonae 

 until now, 



The catalog of Pfarrsdorf f. which you sent.did arrive, but has 

 beer mislaid unf ortunately, so that I cannot use your related re- 

 marks.- Thank you for correcti on of the synonyms, 



The flower of(Ech) Hhodocanthus was very interesting to ne; 

 I ortend it and exanined it nicroscopically« The stränge hair for - 

 mation.of which I know no analogue with cacti, but which is ^re - 

 quent with raany plants, has nothing to do with abortive filaments*
