and the hundred different forms belong all to one genus.- 



I follow your ••fasson au revue* 1 and nust say right away.that I 



liked Sälen 1 s large twigs (? E.D. ) rotatae and tubulosae; the rota- 



tae are really only short tubulosae - i.e. shorter rather than longer ! 



Thus the branches ? ^esides, it is really not a tubulum but rather 



a more or less complete srro^inn- ton-ether (defornation ? E.D.) of the 



flowering organs, which is common In all parts of cactus. What you 



say about germen inclusum say is in part new to ne. One can only 



judge about it if one has disected these cacti.and that is hardly 

 permitted. 



OTS^ibte with cultivated specimens and can be doen only where they 

 crro^j wild in quantity. It is necessary to nake longitudinal cuts 

 (not crosscuts). Get a few longitudinal cuts through flowers of Havyy - 

 mlllaria , ovary and Surround. in*r parts, o^ such snecies , which are de - 

 finitly supposed to be immersae f this Immersion is obviously nothing 

 eise than a growing together of cells, which as just remarked* belongs 

 to the nature of the entire family - o^ a$r least more or less. One 

 difference, which you do not mention in your letter , seens important 

 to ne - Zuccarini was the first to call attention to it; it is that 

 of the II anyvii Ilaria lactifluae and M. a gjuosae ; this seems to ne a fine 

 grouping; to the first belongs of nine only Hevderi (= arulanata, = 

 henispherica ) to which as forns are to be Rdded nicrartha , echinacea 

 and others. These Cactifluae seem to ne to have ovarium immersum, if 

 there is such a thing, which you doubt. Renew the investigation ! ! 

 I do know, that the Upper part of the ovary protrudes, ard that in 

 cutting off the flower one opens the cavity of the ovarium, but a 

 part of the ovary seems to be inserted into the body of the plant - 

 this I believe.
