red all the way to yellow; You will have to study here more exactly;* 

 because this is not clear.. 



P want to teil you right now in sequence, what all I Have to say 

 about Bchinocactt ., First., Mr. Labouret is a professor of mathematics,, 

 who, all of a sudden f , feit it to be his profession, to study the cac- 

 ti f ,He wrote to me, I answered him$ he accepts my tribus; he consi- 

 ders his work as most imperfecta and wants, as I believe,, to publisft; 

 a new edition.. His authority is as good as nilV, and what his Cer. . 

 cir rlf irus is (by the way, not cirrfcifirus; as the word is Latin 

 withbut Greek derivatiorr) } I cannot say exactly..His diagnosis fits the 

 best with those plants, which" you shared with me some years ago as- 

 Cer, Deppei . The plant is a good, beautiful, new one, which I did not 

 describe, as I assumed, that you would do it yourself ; it has flow- 

 ered for me with a large, red flower, of which I can share with you 

 an Illustration^ . Also flower did the plant, whicfr you sent me as 

 Cer.prostratus-, and which I consider to be Cer.pentalophus f% lepta- 

 canthus. It too is pictured in the Bot, Mag. t 3651 as such.. 



The Mäm.daetylithele Lebour is beynd douiat your M.macromeris» , 

 and the £ch. triculeanus is a form of Ech.longihamatus with somewhat 

 shorter* and less hook-formed crooked 1 spines.. 



The cacti by Seeger are well^-grown, beautiful and healthy plants.. 

 Of those which you posess, I have included M.Hermannii, Seegerii , nigra^ , 

 and half and half umbrina. All the others are varieties of M. spinös» 

 sissima and now senilis.. 



What Your Wellborn teils me about the somewhat scaly^berries of 

 M r . macromeriSj Conf irms me in the view, that the plant is not a true 

 Mamillaria. Time will teil. There is no Mamillaria " tuberculis in 

 costas con f luentibus; at least, we don f t know such a one:However. 

 there are several Echinocacti , such as horripitus , odivii, turbi - 

 formis and others "tuberculis mammaef ormibus, spiraliter disposithis' »'
