is not valid ; otherwise Xamarck would have beer right a bundred. tines 

 against Linneus. But I.showed you, that that the name is not M impro- 

 pre M . However Anlacothele has still the right of priority.- What you 

 say about the areoles and the elor.jration and. belonering tocrether, is 

 probably correct f morphologically, a^ I sem^ated. the two areoles, 

 I co^s j dered nore the arpear^oe than the substance. As I have shown, 

 there are Echinocactus, which have the sane wrinkle; in nany it is 

 at least indicated by e^folding o^ the a^eole. 



Now, I want to show you still another differe^ce Q r these plants; 

 with the on.es referred to above, the flower enerres in the nid st of 

 a füll areole, but with Cereus it pushes through the epi dermis of the 

 plant, which it explodes and tears, not through a real areole. Most 

 likely it is the sane with ManfS^ Ilaria , If it is thus with all Gerii , 

 I do not know»- Observe this, if you have the oportunity to see flow- 

 eri^p- plants, 



You know, that Poselger counts the Coryphanta.e with the Echi - 

 nocacti , thus his E.lon hotfodLe ^ etc. etc. f wftich I believe are Goryphan- 

 tae , He was the "first, who called these plants Han*/lllariae (though 

 then unkrowr to ne);he corsidered then Echi^ocactl , sta^dlrg ^ear the 

 theloidefts .- but as said above, the orly £, theloideW i x*hich I know, 

 



has f Towers and fruit stand ing on top of nannillae t not in the areole 

 which is elevated into a furrow nor the basis of the nan' illa, a^d 

 is therefore similar to Anhalonlum 



The seeds are not definite points of ref erence, one find s as 

 f ar as I know, with Cereus plants always nore or less hard seeds; 

 specially hard and bunby with Echi nocereus ; ditto with echino ca ctus , 

 softer or harder , alsnost (not always) black, snooth, with indentations 

 and protuberances;- With Mamillariae they are often lif gter-colored, 

 but even true Mamillariae , e.r. pusilla, have black, hard-coated seeds. 

 The seeds of Corvphanta are all (?) brown and thin-coated, thus diffe- 

 re^t fron Echinpcactus .
