It was, as you See verv lone on its way and I fear that my answer wont reach you much before the end of October. Will it find you still’at St.Louis Poto- si ? You military gentlemen are often subject to such sudden chan- ges that one can not calculate with any certainty on the future.- much less than we other poor nortals. So you are a friend of Mr. Chechineer who together with Prof. Schimper was very kind to me durine ny short sojougn in Stras- burea7 or 8 years ago.and Alex Braun,my friend of nearly 40 years standing,and constant correspondent, where did you get acquainted with him ?But it did not need any kind of introduction,where you had the most influential of all, the interest of science itself, .and your zeal in the study of the botany and especiallyvof my favorites, the Cacti,to recommend you. Equal interests and pursuitshake quick friends! I write to you in English because it is more famillar to me than the French,but mischt perhaps have done better to write in Ger- man,which language from your name and from yonr referring to Braun and Buchinger must be familiar to yousbut as I was not quite certain of it,I prefer to address yiv in English. I had expected that the French expedition in Mexico would be fruitful in the exploration of the resources of the country, Its na- tural history,etc,just as such military expeditions have opened to the world of Science Egypt, Algeria and other countries - but hither- to I had not heard of any scientific results -— so your letter was an unexpected and almost abandoned good fortune for me ! When the cacti of our southern frontier got into my hands, some 6. 8 9 10 MIıSSOURI . BOTANICAL copyright reserved GARDEN 20 years ago, and I besan to study them, I was struck with the cors- ness, the want of scientific precision and spirit,with which that most interesting family has been treated. Even ereat botarists, like and Martius De Candelle have not done them justicesnot to say anything of the mess of dilletanti, who did more to confound and confuse Science than to ejucidate. I besan my studies a new, ab ovo,.based on the immutahle principle, that the flower and the fruitification only can leadon, and must lead on,to true scientific results, in that we can study Cactaceae not any better than Oaks or Roses from the mere oreans of veretationand that we must have the flowerand the fruit of every species,and know them well in all their details,before we can say that we know a spe- cCles of Cactus. I have been further well aware,that a great many species,comnme- morated in the books and in Garden Catalogues,are merc. varieties, _ so that the number of real species mus+ be vastly reduced; but I al- so Knowthst only a botarist in loco could discover the true limits of species;only one who sees a great many individuals and studies them can learn to distinsuish the essential from the unessential'! cha- racters. I would not consider that I knew a species if I was not well acquainted with the flower and fruit,ard I would hesitate to say that I knew it well if I had not seen many specimens,if possible under differentcircumstances in different localities etc. so that I could Judge of the derree and the limit of their variations ard separate the constantand essential from the accessory,changeable and unimpor- tant characters.And such an opportunity I never enjoyed,and such an opportunity do you now have IImprove it by all means- and anything I can do to assist you shall be most faithfully and che erfully done. Of course, we have to take into consideration what our prede- cessors have done: Y 2ne;but, thoueh frequently they have paved the way for 10 MIıSSOURI . BOTANICAL copyright reserved GARDEN .- 3 Pn us,helvped and lishtened our labors,thev just as often have it with rubbish,which to clear away is as necessary as it is un - pleasant and often difficult task.- The horticultural collectors and travellers,the rreat NL SEE establishments,anrd - pro pudor - the hotarists,who worked in their interest, have made the task of the scientific botanist quite a difficult one. I! If I knew, how to send you books,I would yake the pleasure to pre- sent you with copies of all my publications,though, as you justly remark,you are stationed in a country,where the species known to me scarsely occur.-I must add, that with my present views, I would can- cel quite a number of species,which I have formerly admitted; but, to my excuse be it said,I never had an opportunity of studying a ereat many specimens -— and never saw them egrowing in their native homes II wish this good fortune was yet in store for ne. Thoush the sheet is at an end,I cannot close this letter yet- however fearful that your patience may have become exhausted. Not only the species of Cactaceae are in great confusion, but even the genera are by no means well known or well determined. Two zXenera only seem to be perfectly well characterized and that is Opuntia and Peirescia;the former especially; Peirescia is not so well distinguished‘ by its seeds,as Opuntia is; Rhipsalis is per - haps also well distinguished,and perhaps Melocactus, of which I have very little; but the transition from the most humble Mamillaria to the Giant Cereus and Pilocereus throush Pelizocacti (? cannot read E.D.),Echinopsis ‚etc. etc. are-so geradnat that satisfactory li- mits will be difficult to Sind. I had formerly relied a good deal on the structure of the seed and the direction of the cotyledon, but find that the char TUerived from them are not quite constant; I must accept this unpleasant discovery,as we must accept many facts, not in accordance with wishes and preconceived opinions. The fact , 10 MIıSSOURI , BOTANICAL copyright reserved GARDEN that the same character in the Coriferae,thoush still relied omas one of the fundamental ones is amazing that family is not always nor absolutely reliable,must console us a little. We have here two close- mn cumbent ctotyledons | The szsreat number of Genera constructed by modern botanrists, and still multiplied by some charlatans,must be frowned upon,as they can- not stand before scientific’ engauiry. I would bes you to make the most minute and extensive menoran- da from the living flowers and fruits; pay attention to the time of operinge of the flowers,matutinal, vespertial.diurnal or nocturnal.- or which flower by day or nisht; some open earlier,than later,and re- main open longer or a shorter time. Color of flower and fragsrance, called) or laterals if the latter,wether high or low,i.e, from la - ter or older parts of the plant. Proportion of the parts of the flo- wer. Condition of the lowest part of the tube - below the insertion of the stamens. Insertion of stamens lower or higher up and in many Cerii the separation of a "corona" of stamens from the balance. The fruit is most important and ougesht to be carefully’descri- bed -— dry or pulpy - external covering - shape and size - kind of irrerular Schispence if any - time of ripening. Seeds can be preser- ved and described afterwards at leisure. Among the best Inomm Cacti seem to be the Peiresciae (Peres- * kiae in modern literature,E.D.),several species of which from Mexico are only known and described after Morieu and Sesse's drawinss, which were made use of by De Candelle,. Careful examination and study of all of them'seems of the greatest interest,and the collection of fruit and seed’is indespensable. Collect specimens of their wood. 0 1 2 3.4 | 9 10 Mıssour! . BOTANICAL cm copyright reserved GARDEN The the Opuntiae are so little knom, but much confused, because their flowers and fruit habe not been well studied.- Among these my favorites, the Cylindroupuntiae, of which you have several about ee 2 St. Louis, are least knowm they never flower in Europe, and a stu- dy of their organs-and collection of’them is very imp yortant,. The au.,...ga0t1 are, 4 belleave, most prevalent in your neieh- borhood’and they also merit close study. .For myself I should wish to get (before all) fruits and seeds,the latter best preserved in the pulp of the fruitz; next drlied flowere (split when they will’ dry better - and not hard pressed.) if possible,with a small seretion of the plant, .to which the flower is attached. Living plants are diffi- clult to send’ (not to be sent in our winter !),and if sent,ougsht to be in small and young specimens,.- I may have overlooked’a good deal in this hastyrvcommunication, but will make up, as our correspondence continues and increases as i nope, it will, Do you study other plants too ?"I have paid particular atten- tion to Cuscuta - Euphorbia, especially"the low one belonging to Anisophyliae - Junci_ - but before all others to Pinus , or with Abletinac ‚ of which the male and female flowers and the cones and seeds (with their appendiges) are important.- Any species will be most thankfully received, and whatever I can send you in return will be most cheerfully done.

BOTANICAL copyright reserved GARDEN St. Louis, Missouri May 4,1866 Mv most honored Friend Today ET finally received agaima sign of life from you,after I had believed a long time,that either my letter never came into your hands,or that your professional activities kept you from the studies of the Cacti.You did apparentliy receive my letter,which was written nearlv a year ago,but your reply of past November has never come into my hands. What happened to you ?° Could you give me a short synopsis of the letter ?° Moday, I only write to you,to tell you, that your letter with the enclosures is in my hands,,that, however, the little casen has not yet arrived.If you should have the opportunity to send something from Browsville in the future, it should be of importance to know,that our postal service handles packages,which do not contain written mat- ter and are not sealed, at very low costs,namely 2 cents for each 4 ounces. I frequently receive in this way plants,roots,seed-cones,and that even from California.- 5: hope you studied the Cacti in all their conditions quite tho- sio rouehly,so thatlthe surface skipping| routine may finally come to an end, -whichzs besides the difficulty of preserving these plants, ‚has kept them so much from the real scientific botanists.. You praise my thorouehness; that is very kind of you,but the glory is not mine, but belones to the industrious collectors,who deliver the material'to me. I myself, I want you to know, have never seen a cCcactus in the wild eX- cept this Opuntia Rafinesauii(0.R Engelmann is now Opuntia compressa, Mächbr. E.D.) You are just the man and in just the right situatiom to study these plants thoroushly and to discover the no doubt large cir- cle of variations. Do you possibly agree with me,that a large amount of now accepted species are only different forms,which all meld into each other and are connected throueh middle members. Without doubr, I BEER: een 0) 1 2 3 4:5 6 .7 8 9 10 MISSOURI .

It seems very probable to me,that many of the yellow flowering species of Coryphante are nothing but,.forms of one species, | zz ‚.ealöarata,. cofnifera Thekeoljmordes= ©, Echinuspredtans god” a etc. and may-be even the C&l- Carata from Texas may all belong together. You alone are able to make exact examinations, further it will be of importance to study the ver- satillty or constaney of the flower colors, their size ‚their position on the plants will naturally be constant. Observe certainly always the implantation of the ovarium"into the body of the plant with Mammi- laria and the juice,if sweetish or milky; and if you can handle it at all} bring dead plants or parts of them as proof, and, if possible , dried inflorescense and fruits. Descriptions, regardless how carefully made,are always incomplete,as one becomes only later aware of various items, which cannot be filled in if no specimen is available. As to floral position of Mammillariae I have found out now,that intermittent forms between Eumammillaria and Coryphanta do exist; e.zg. M._barbata,which fbowers every year for me, has been od interest to me in this rezeard and at the same time appeared suspicious and against po- licy ( verbatim transl. "against police" E.D.),pBoduces its first blos- sem In serıng from Thea arlles df the last .„.„....0s.3..+.-fron the past year,but all the following come from from the agxiles of the same Spring Also, the opale-green fruits are more like those of Coryphanrta ‚thougsh the flower is small. Thus, Grahami,Wrieshtii, and others may belong here. That you found Mam.macromeris so far from El Paso,I almost doubt I Try to get seeds, it is unknown to me, and the plant is not in cultivation. More likely you may encounter the yellow,very large M. Scheeriil,which was actually first discovered in Chihuahua. The identity of the mexican O,.vagihata and O.frutescens I have known a long time. You also see from my research,that I hoped’to be 10 MISSOURI _ BOTANICAL copyright reserved GARDEN able to distingeuish'a thick-stemmed,fleshy plant from New liexico with very bumpy fruits; that may hoiever not have been successful.- Berlandieri‘ Cereus 4 ıL may belong with C.pentalophus (C.leptacanthus) , but C,procumbens is different, as the seeds indicate. Cer,tc:ierosus » flowered often here and I made the same observation about the position of the flowers,which you communicated to me. Excuse me, if I protest aceainst the name edulissimus;it is un-latin ; better name the plant sapidus,which means "tasting zood". But I do not want to start ceritizising now; as soon as I have read and studied vour notes, I shall write again;and specially after the case zets into my hands. Be sure to observe flower and fruit of the eylindrical and elongated Opuntias carefullyz as they never flower in Eu”ope, it is specially important to observe them in their native land;. It is upon this that my remark”about the change in form'and the limits of variability of species-has the strongest reference; the seeds of then, as you know,,are very different and very variable,whereas the Platopuntiae divert very little in their seeds. I want to point out to you specially one Opuntia, my O.stenopetala, which has been collected just in your territory by Dr. Greeg on the battlefield of Buena Vista; you have a picture of it on the maps of the Boundary Commission..Gregee's specimen did not have formed stirmata and no ovula,as far as could be seen from the dried specimen; here Opuntia erandis is being cultivated,which I almost believe is the same with very similar,beautiful orange-yellow flowers, stigmata very peculiar, not uniform, more pointed’ with stigmatic papillae below the tips,few ovules in the ovarium, it never set fruit. I would much like to obtain a fruit; dry ? fleshy ? seeds ?'° Opuntia arborescens,which is probably O.stellata and O0. Kleiniae flowered here last Summer.- Du you draw and peint ?

But enoush of all this now. More the next time. As I would like to become personally acquainted with my correspon- dent,please tell me where you are from and what your scientific field is. I was born in Frankfurt a.M. (on the Main River, E.D.)in 1809 and went in 1832 after firishing my studies to America and settled in 1835 in St. Louisgwhere, as you know, I live as a doetor. I began my botani- cal studies already as boy by preference,arnd do as much in this science as my profession permits. Durinz the last years I have not published any more about Cacti, but continue to study them as opportunity permits. Since several years I have been occunied intensively with the study of the Corifers,and flowering and fruiting specimens of them from Mexico,of which I possess already some from Dr. Grege,would be most welcome II would love to see Abies relisiosa, which grows near Mexico City, in flowers and with cones. Branches I have from Dr. Grege.. During the last six months I have been completely occupied with the rushes and I am about in the process to publish something about thenm.. Any kind of rushes, specially in fruit,would be most desired.. You have the pricipal publications of mine in your hands, but, as ssiAd, I do net accept (any more\all) which I considered correct some 10 years back. Since then, I only published short notes and nothing about the territories in which vou live now, One more questiom, Did you send anything for publication to Europe 6.7 8 9 10 MISSOURI .

BOTANICAL copyright reserved GARDEN n St. Louis May 30, 1866 Honoreäd Friend, I went now carefully throush your descriptions of Cacti, after I had also received your seeds. These interested me a great deal, and I have really very little to add.. Your descriptliom of the plants, statement of dimensions,flowering position,flower,. fruit and seeds are mostly sufficient, and you are up to now the only person to have made good use of the opportunity to observe these strange plants on their native soil, according to the de - mands of today's science, May-be you could have mentioned the Fu) Ei state of the wood after destruction of the moist parts..Only of one do you mention'the explosion of the fruit (Tetego),which does occur with C,gisanteus, the others apparently do not burst. The associated Cacti and wild plants could have been provided in more detail;only once do you mention the region for sugarcane. It becomes apparent from \your exact description of flower and fruit,that there is quite a number of of externally similar but most likely very different columnar carti . You have seen yourself that Pilocereus cannot be geneti- al a ah from Cereus, and säad so,and species may be found with smaller or hardly noticeable beard and thus form the trans- ition to the common forns,. Your Cerei with flowers at the summit I cannot stomach. You too, as I am, are also quite dubious. Coula this be the ter- D ‚e? minals of old twigs,possibly of the preceding year,ıwhich instea of continuing growth in the current year,set flowers ?'If you have the chance,please examine this point further. By the way, no place existsSand least here "junior in vesta magistri". Our teachers in the knowledge of cacti are dwarfs, not excepting the best, because they did not have the ma- MISSOURI . BOTANICAL copyright reserved GARDEN ders 2 um terial, and generally’ (my most honored friend Fritz Salen not ex- cepted) the broad botanical know-how, Education,to master the sub - jeot,. You’ are correct in seeing the difference between genera dis - appear by examining frequently in nature. Scientific Botany will re- duce the numerous geenera forcefullyy If we beein to reduce the mass of cacti, the UÜpuntiae must be put in order first,followed probably 4 by the Peirescia (Don't you see any species of this interesting ge- nus,of which Dek@indelle pictures so many mexican species,which singe then nobody has seen again and he himself only the illustrations),, Then, however, the difficulty starts all of a sudden. The position of the cotyledons is not entirely reliable, as I have seen Cereus from Cuba with accumbent cotyledons. The seed of (blank space,E.D.) to which you ascribe the same, I have not yet examined.- Melocactus is probably a good genus.- But from the siant columns to the smallest Mammillariae some limits have to be drammz mav-be, as mentioned, thronuesh the cotyledons,. % r N: -f, si Er puren j ‘) °. R Your ER was specially important for me,because flower, inflorescens, abundance of flowers, even the fruit provided a complete transition to Rhipsalis I!!! And if the floral tube would be even shorter and the seeds not as bumpy,no human being could A + separate them from Rhipsalis ! This species is the bridge between the two genera. Und C. marsinatus follows suit, but already more like Cereus. You rarely mention the time of day when the flower is open. a Niceht-bloomers are probably frequently still open in the morning, thoueh not at noon. When brougsht into a room for the opening of buds, observation of the hours of flowering mav be carried out best. The caducous (drooping, falline off.E.D.) tuft of C.Heppenstedti * is a strange phenomenon. Does it eo around the entire twie or is it ku lateral, 10 MIıSSOURI . BOTANICAL copyright reserved GARDEN - £ - Pr That is, with C, lateralis ik always points North and with flarispyianus into various directions |! Also interesstine I With some Pilocerei flowers arise from older, with others from the top-most areoles;and with some the flowerine part of the stem is marked on- 1y throush the wool;with others (as with my C,Schottii) the entire flowerine section is built different, and for Schottil much more an- gular and the areoles positioned much closer. Rarely do you mention the number of scales on the ovary or even the number of sepals and petals,which seems however important; do not miss the length. of the free söfe at the base of the tube;form and leneth of stigmata (thick, ‚ thin, bDlunt,. pointed ).. Did vou dry flowers, spine-bundles, crosscuts,pieces of frulit ! Do you have drawines of plants in bloom ? You have seen so many species, that you can group them better’ than anybody else; you should kry this,and rely thereby more on flowers,fruits and seeds than the ve- getative parts. Be sure to observe the geoerraphical distribution as to expanse and altitude. But remember, that only the larser mexican citles are xenerally knomm and that travellers mostly refer irresponsi'b |y to small villages or haciendas,which nobody can find again easily. How sad, as we hear from our newspapers, that your time in Me- et O xico will come an end this years For Maximilian, I fear,things are worse.- Is there in Mexico another French or Austrian officer who is interested in botany ‚specially in Cacti ? How do you plan to publish vour observations ? Do you send seeds to Europe and to whom"? ’ cr Write to me as often as time permits. Did you receive my letter of My 797 Still more auestions, which came to mind while going throush your descriptions. Pil.cetensis fruit really naked ? How is the ova- MISSOURI _ BOTANICAL copyright reserved GARDEN = IL . ry ? I assume a few scales are on it ? I ask again about C, Tetyo, which is supposed to carry its flowers "aux plus jeunes areoles" (in the voungest este). Is that so -I snoke often ahout it. Yon forgot to mention the color of the fruit near Babosso; but first Id like to know if the fruit is smooth or bumpy. I believe I spoke already earlier about the unreliability of the species. Do not tie yourself to it: go without worrying your own way; but you must try to always recognrize the old species azain. That has become very difficult throush poor descriptions,which are mostlv based on weak garden specimens,and which in very few cases show flowers or fruit; and when such were vresent,then they were incom- vletely described. Your Cereus edulissimus,which I propose to name saridus or de- liciosıus ‚„seems,accordinez to the description, to have much simila- B rity with C. princebs,which erows from Tampio to Metamoros ( my erro- 4 neously so-called C.variabilis) but prigcens_ is weak,leaning on shrub ery,mostly 3-edged and the seeds are different from those sent by you. The seeds from Metamoros are similar to yours of C.marsinatus, shiny,rather thin-walled,very fine-bumpy with good marrnification (chagrieu ) but 34 mm long..Are the two branches, which arise from N i . C.candelabf® at the same heishth and where they are positioned at the stem, do the upper ones cross with the ones just below (decussate g E.D.). Thus if the first pair points to North and South,the next points to east and West. Did you not observe such an arrangenment ?

Jan 16, 1868 Ans. Jan 27. Post. Mark Dec. 29 Auxerre, December 19, 1867 My dear colleague and very honored friend, I really do not know if you would like to pardon my long silence. I admit that I am guilty of great negligence towards you and I will have difficulties excusing myself. You remember how difficult our correspondence was while I was in Mexico and in spite of my good intentions I finished by despairing in not being able to establish regular communications with you. Since my return to France, that is since last April, I stayed with my family in Strasbourg, and during this time Tabandoned nearly completely my scientific occupations and delivered myself to the pleasures of rest. Ihave recently reinitiated my duties within the military and have been placed as main physician in the 99th. regular Regiment in the garrison at Auxerres.(department of Lyon). I propose to utilize the free time that my duties will allow me during winter to review and place in order the notes that I wrote in Mexico on several branches of the medical and natural sciences. But before anything I want to give signs of life and ask you if you would still provide me with your precious comments, advice and experience. The last letter that you should have received from me was from San Luis Potosi in the month of October 1866. At that time I was still unsure of the subject matter of my previous letters. It has not been until the last days ofthe year 1866, while in Mexico, that I received your two letters from the previous month of May, in response to the envoy of documents and seeds that you made through Matamoros. It took more than seven months for the letters to arrive. They came from San Luis Potosi where they must have been laying in the Mexican Post Office. During that time I frquently went to ask if there were any letters for me and the answer was always no. If I have not answered you while I was in Mexico it is because two or three days after I received them, I had to leave to Mexico City with all the sick patients ofthe army that had remained in Mexico. I was in charge of a moving a group of patients, which I did in small stages, I had occupations beyond my limits. We had to stop in Orizaba for one month, before finally descending to Veracruz where I arrived in the last days of February. It was really my fault not to have answered you at least to tell you that I had received your 2 most interesting letters. I hope you will excuse me, taking into consideration all the occupations that I had and the circumstances in which I found myself. You asked in one of your letters, which the destination was of the first series of documents that you sent me and in what way I planned to publish them. After my return to France I have wanted to write a Monograph on the Mexican Cacti, making it as complete as possible. Unfortunately my medical obligations, which for me have always been more important than the botanical studies, which I cultivated as a pastime, did not permit me to visit as big a portion of the Mexican territory as Ihad wanted and which would have been indispensable, to produce something as complete as possible. In all honesty I traversed Mexico in all its length, from Veracruz to the Rio Grande del Norte, but could not visit a large number of localities that therefor remained out of my explorations. I thought that the year 1867 would allow me the occasion to see other parts of this country, towards the Pacific, which until now seems not to have been explored. The unfortunate turn of events that occurred to our expedition and our premature return to France, put a stop to all new projects. To my great regret I find it impossible to do what I wished and my projects will remain quite incomplete. In the 8 | ) 10 MISSOURI . BOTANICAL copyright reserved GARDEN meantime, even ifthey remain incomplete, I consider it my duty to science not to let my notes disappear in the depths of my notebooks, and to publish them the way they are. In spite of there imperfections, they will provide some more material in the knowledge of a vegetable family so little known until now, and will allow future botanists, luckier than I, to complete them. There are no lack of studious Mexican men who will ask no less, I am sure, than to study them scientifically. The botanical richness abounds in their country and could provide a mass of interesting material. But how would they react if they saw a book published in Europe with all the Cacti that they have directly under their eyes? One ofthe most important points that would bring them much help, to decipher this chaos, and which until now has nearly completely been neglected by the botanists ( I make an honorable exception of you), is the exact location ofthe plants. If one knows that in a given location, one never finds but a certain number of very rare species, it will become simpler to verify their synonyms and to correct all errors. As for example in a memoir by Poselger (1853), that my friend Bushinger sent me to Mexico, I found some descriptions of species in their localities. These were of much greater help to me to relocate the species. At La Soledad (close to Veracruz) I easily found his Pilocereus scoparius; in The Canyon (between Orizaba and Puebla) I again found his Mamillaria Karstinni; some leagues further close to San Agustın de Palmas, his Mamillaria cirrosa ( that is nothing else than the Mam. grisca Salm. malletiana. In Saltillo I again found his Mamillaria Leona and the Echinocactus Saltillensis ( that is the species that I sent you seeds of, under the name of Mamillaria robustispina; I believe these names are Synonymous to the Mam Schurii ?! I don’t have flowers, Poselger says they are large and flesh colored. Could itbe a variety of the fleshy flowers of your robustisima? it is possible). His Echinocactus Salinensis ( var. ofthe Mam. cornifera type of scolymoides) I found again at every step in the surroundings of Monterey and Salinas where the stems are simple and different from its neighbor which is less vigorous and which you have described under the name of Mam. calcarata! In the Rinconada ( between Saltillo and Monterey, I immediately recognized the Echinocereus capricornis and loptothele. I recognized your Opuntia stenopetala, without flowers, because I looked for it according to your instructions, in the south of Saltillo. ( I looked for it vain in the fields of the Battle of Buenavista, which I explored in all directions, and I saw only Opuntia with flat leaves as on the Op. Dillenii, that is to say, the Mexican form of the Opuntia Engelmanni). I would be able to give many more examples that demonstrate the benefits of knowing there exact locations for future research. Another indication which has great value for verification and for research in the field itself, is the mention of the indigenous names. There are many species that have a very determinate name, and that the natives recognize very well. For example you already recognize the Garambullo, the Tetejo, the Chiotilla ( that I erroneously thought was a synonym of the Cereus Durmetieri, that I later found in Queretaro;. the Chiotilla is very distinct). The Teconostla, the Pitaya, the Pithaya, etc. etc. If you ask a native to show you a Garambullo he will hesitate but one instant. Certain globulous species also have distinct names. For example ask a native to show you Peyote and he will invariably show you the Anhalonium (Echinocactus) Williamsii. Or he will perhaps show you the Anhalonium prismaticum but he will point out to you that it isa variety of Peyote, but not the real one. ( you can see that the natives recognized before you and the narrow difference between the similarity of the Echinocactus Williamsit and the Anhalonium). 8 ) 10 MISSOURI BOTANICAL copyright reserved GARDEN 3 It is without a doubt that in the study of the Opuntia and mostly in the cultivated species, the indigenous names will be very important. I unfortunately did not have the time to unscramble their difficult Synonymy. In the meantime I was able to note many indigenous names, and reassure myself that they always designated the same species or varieties. For example: Mazul or Mazula (Opuntia stenopetala); Quija (thej is pronounced like in German)( Opuntia Dillenii), Coionostle (Op. imbricata); Tasajillo (Op. frutescens); Clavellina (Op.tunicata); Duraznillo (Op. fulvispina); Toconostle (species with an acid fruit like the Cereus of the same name); Alfajacuya (Op. maxima); Camuessa (Op. crassa?). Among the species cultivated more or less next to the species ficus indica: la Pelona, la Blanca, Amarilla, Mansa, Ceniza, Chavena, Tuna de Castilla,etc. and then the famous Cardona de San Luis Potosi (new species?), la Tapona (sp.?), etc. etc. Allthese names are perfectly known by all the natives. It would be very important to note them so as to facilitate future synonymy. I was willing to establish a general pattern, something like a canvas in which some details would be missing, but could be filled easıly by future explorers and specially by the native scholars. In the first place as I already have mentioned, my medical duties did not leave me enough free time to make lengthy and multiple excursions. F ollowing, the official cooperation, that is to say the facilities that could have been offered by the military, were nearly completely nil. It is true that a scientific commission for the exploration of Mexico was established in Paris. There was a big cry that they wanted to know the Mexico, like in the past the scholars that accompanied Bonaparte, made Egypt known; but this commission could not utilize the elements that they had available; in the expeditionary army they could have found a certain number of studious men that could be sufficiently instructed to furnish precious material; but scientific work is nor honored nor encouraged in the French Army. The Paris Commission did not send a single member to Mexico. They were content in sending some poorly educated "scholars” who were not part ofthe Army and therefore did not use its facilities to travel throughout the country with the regiments. Nearly all ofthem thought it was more comfortable to live for the duration of the expedition, in Mexico City or in other cities of good size. Botany was represented by a brave and dignified man, Mr. Bourjeaud, who is usually employed in the herbarium of the Jardin des Plantes in Paris. But he knew nothing about Botany as he was employed in picking up the leaves from the floor and placing them in paper bags. He was good at that but this was insufficient in a country where the vegetation is represented by the succulent plants, Cacti, Agave, Alves, Euphoria, Dalyrıdion, Yuccas, Palmiera, etc. etc. Certainly a capable collector could render great services, but would have to be directed by a botanist capable of studying and describing on the spot. In addition this collector did not know how to ride a horse, and could only be in a herbarium in Mexico or in Cordoba, that is to say ın places that have already been visited by hundreds of botanical collectors. There was also a man in charge of sending the most remarkable plants to France, from a horticultural standpoint, but this one seemed to me to be only a common gardener, deprived of botanical knowledge that could have been important to him. His envoys, by the way, contained very little material. In the summit of the Paris Commission, botany was represented by Mr. Decaisne, professor of the Jardin des Plantes. During the first months of 1864, as soon as the commission was founded, I wrote Mr. Decaisne, to offer him my services, giving him an account of the work I had accomplished. I offered to send him the herbs, and to MIıSSOURI 6 .7 BOTANICAL copyright reserved GARDEN 4 study on the spot the plants and families that he would specially want, that is those that could not be prepared for a herbarium. Mr. Decaisne had personally known me for a long time, as he saw me frequently in The Jardins des Plantes of Parıs; he knew perfectly what I was capable of and what was above my talent. I was going to tell him that my offerings were entirely disinterested, that is to stay, free from pecuniary remuneration.. The only thing I asked for was an official recommendation and mostly the facilities to be able to Change residence according to the needs of my work, without leaving the military, and to accompany the expeditionary regiments ad lıbitum, at my discretion. Well! can you believe it? Mr. Decaisne did not have the politeness to answer me.it took a whole year until he asked me through is collector, Mr. Bourjeau, at what stage I was with my work and if I did not have some memoir to send him. You can imagine that I told Mr. Bourjeau, to relate to his boss that I had no accounts for him. You can see that I was not officially encouraged to work, and that I was disgusted. I did not do research work that I could have done had I received some slight stimulation. At the beginning I wanted to do a little bit of everything and study the flora and its details. I made large herbariums that went to honor Mr. Buchinger and that he related to the German specialists. For example the Fougeres went to Leipzi g with Mettenius, the Lycopodiacees to Berlin to Mr. Alexander Braun, etc. But I very soon recognized the proverb: he who embraces too much cannot grasp it, and that I did not have sufficient time. I also began by studying only the Cacti, specially those that were most interesting as they were more unknown. Now, in spite of their very incomplete state, I would like to place my notes in order and publish them. However while reviewing them, I hesitate and I find at each step, many difficulties, some of which I would like to present to you. The greatest problem is the delineation ofthe genders. The genders are always groups that are more or less artificial, This is more prevalent in the Cacti family than in others. Nature rarely forms perfectly circumscribed groups, and is usually preceded by graduations and by transitions, both of which are insensible. Then they never form Continuous series: it can form a line replicated on itself. Points that are far from each other will return and unite at the beginning of the series. In the state of our knowledge it would seem one could clearly Separate two large groups. the Peirescia and the Opuntia. Now in those two groups do you not have the transitions such as P. poppigii and tubulata? By the way the Peirescia are very little known to us; on my part I did not encounter them in Mexico, therefore I cannot tell you anything about them. The Opuntia seems to have bark that is slightly elongated, hidden partiy by wool in the vertex and compressed between the tubercles that increase their numbers. The Anhalonium Williamsii is the exception; its bark is entirely similar to the Mamillaria. Therefor I believe we are entirely in agreement that we can reject the fact that the emergence of the ovary is a basis of some classification ofthe generic character. If I have talked to you about this it is because in your letters you called my attention to this subject. I wanted to tell you about my ideas, to corroborate them with yours. On the contrary, a character that seems to have been conserved and which is of great importance, because there are some species than form the transition, is the one derived from the bark, wether it is smooth or squamous. Six groups in which nature tells us they are of the Cacti series are: Eumamillaria, Aulacothele, Anhalonium, Melocactus, Discocactus and Melacocarpus. I think that we-can form a large group that one could name Melocactiae or Gymnocarpae. 8 ) 10 MIıSSOURI BOTANICAL copyright reserved GARDEN e The genders that comprise it have among them numerous similarities and one can make groups that can be circumscribed with certain preciseness. The Melocarpus would form the transition of the Melocactus to the Echinocactus. They are different because of their smooth bark and the others by their deciduous cephalium. They seem to form a very natural group. They also distinguish themselves according there homeland, which is a characteristic, which we would be mistaken not to take into consideration. The Melocactus constitute a natural group recognized by nearly all botanists. These have multiplied the species.. They also distinguish themselves by their location as they originate mainly along the Mexican Gulf Coasts, or at least in the hottest areas of America. I have nothing to say about the Discocactus, that I do not know. Its floral tube is bare and elongated, this is a sufficient differentiation. In regards the plants that comprise the three groups that you have united into the common group of the Mamillaria, the characteristics that differentiate them among each other, merit our highest degree of scerutiny. The more I reflect the more Iam persuaded to think that each one of these groups is reduced to sub-genders instead of forming a distinct gender. In regards the Anhalonium, you yourself wrote some ideas in the Bound. Comm. Rep., and I agree with you entirely. Like you, I would add to them the Echinocactus Williamsii and the Pelicyphora asilliformis, that according to me cannot be separated from the Anhalonium. The flowers are entirely similar to the A. sulcatum: they arise from the center of the woolly vertex; the seeds are less distinctly tuberculated, as in other species where they are verrucose. We have therefore six species of Anhalonium: A. elongatum, prismaticum, fissuratum, sulcatum, asilliforme and Williamsii. In regards the Leuchtenbergia, I have not found them in Mexico and I do not believe they can be catalogued together with the Anhalonium. The descriptions of Salm, seem to indicate quite clearly that the ovary is squamous; the flower does not come out ofthe middle of its woolen parts, which is so characteristic of the Anhalonium. Then also the extraordinary length of the floral tube would in itself be a reason to make an individual group of this singular plant. In regards the Eumamiillaria and the Coryphanta, it seems to me that there is a line of demarcation that is very clear. I propose two distinct genders. The first I would name Mamillaria and the second Aulacothele. The name of Coryphanta does not seem proper, because certain plants of this group have flowers as small and even smaller than the Eumamillaria. Some have flowers that are as big or bigger. The name Aulacothele responds much better to the principal characteristic seen on it. I do not agree with you entirely, when you state that the principal distinction between the Eumamillaria and the Coryphanta is the lateral or vertical position of its flowers. This property is not sufficiently constant, if under the name of vertical aureolas of the vertex one considers the species with hidden ovaries. There must be some that do not have hidden ovaries. I doubt this very much. This is by the way easy to verify. I will try to do this next spring and perhaps you can do the same. I remember having been struck by this fact, which is Contrary to my lectures in 1864 and 1869. I paid very little attention to this and could not specifically verify the species on whom I observed it. As far as I can remember, some of the macrothelae, such as the Mamillaria aristina, pentacatha var. San Luis, Mamillaria Schetasii, Mam. carnea. I believe I saw the same thing on the Mamillaria acanthophygnea and Haagiana, and I believe I could prove it. It was not until 1866, in Monterey, I thought of placing this subject under experimental 6 7:38 9 10 MISSOURI BOTANICAL copyright reserved GARDEN conditions, but then I had only three species of Eumamillaria, pasilla, texana, applanata and the species of which I had sent you seeds under the name of M. glabrata. ( Atthe Universal Exposition of Paris, I saw plants named glabratta, they are different from those from Monterey, and I must say would respond differently to those describe by Salm). Therefore all three of these species have an external ovary. I see on the drawings of your Bound. Comm Rep., that in all the Mamillaria flowers that have been drawn, the ovary is very distinctly marked and therefore is not immersed. There would anyway be species in which the ovary would be immersed, however this would not be sufficient to make the basis of a classification: it would be much to inconstant and could say Eumanmillaria ovarium emersum or plus minus immersum. You have studied the emergence of the ovary in the Anhalonium. Tam going to prove it in the Anhalonium prismaticum, elongatum and sulcatum. This last species forms the transition with the Pelecyphora, who under no condition one could consider a distinct gender and which is nothing else but an Anhalonium. I did not see any open flowers, but there position just as that of the fruits is identical with that of the flowers of the Anhalonium sulcatum, and I did not see a single case where the ovary was emergent. It is true that one finds the seeds between the tubercles; this is because the flowers are vertical, the base is small and like in the Anhalonium they are found compressed between the tubercles of the summit that start increasing in number after the blooming season. But it is without doubt one of the numerous errors that escaped from the author. This species originated in Mexico and all the observations of species that can be found again in large distances, are, in my opinion erroneous. The greatest number of Aulacothela seem to come from the northern provinces while the Eumamillaria are found mainly in the south. Now, after I have told you which the genders are that I plan to admit in our First Section (Gymnocarpa), and which are the fundamental characteristics that to me could differentiate them, I have to tell you about a plant that you no doubt know better that I and that is an absolute part of the First Section. This plant, of which I would like to have your advice is your Mamillaria micromeris. I found in the arid and porous plains, approximately two leagues from Saltillo, on the edges of the route that goes from Saltillo to Monterey, some rare specimens of the plant that you have described under the name Mamillaria micromeris var. Greggii. I was unable to preserve any of them, they all died before arriving in France so that I was not able to examine them again and all what I have to tell you about comes from my notes. I will copy word for word what I have written in my note books in regards this plant. “ Globulous, simple, sometimes branched, poplycephalic, after destroying the head. The largest specimen that I found is 4 cms. in diameter.. It corresponds entirely to the description of the Mamillaria micromeris var. Greggii, given by Engelmann in Bound Comm Rep. The samples did not have flowers (November 1869), but dried and mature fruits in the midst of the wool on the summit. While carefully dissecting two plants, I was convinced that the inflorescence is entirely central or vertical, as well as in the cornifera. The vertex is profoundly depressed and sunk in. On this species ofthe high plains the mamilla are small and poorly shaped. On its summit there are already the rudiments of the thorns and abundant and lengthy woolen down. This helps form the species with the thorns of the cephalium, that makes the plant so unusual” 10 MIıSSOURI 5 JE BOTANICAL copyright reserved GARDEN 7 “ Ireassured myself in the most positive manner, by careful dissection, that the flowers and fruits arise from the young summit mamilla and not from the axilla that at all times are bare all the way to the vertex. The fruits that I examined arise from the superior portion of the areola, immediately below the silk fascicles and thorns. Later on there was no trace, nor scar, nor ridge on the perfectly developed mamilla, underneath the place where the flower is found” “ The shell of the seeds are as they have been shown in the plates ofthe Bound. Comm. Rep. The seeds are scaphoid: I found this particular shape only in the seeds of the Echinocactus capricornis, that grows a few leagues farther away, close to La Rinconada.” Which gender should this unusually small species be found in? It is surely not in the Eumamillaria that are essentially characterized by the axill ary flowering, and in which the flowers are essentially lateral, sometimes subcentral ( that is to say arısing from the axilla ofthe mamilla from the same year, but never arising from the young mamilla. Could this happen among the Aulacantha? Therefore the general characteristic on which I will found this gender (flowers arising from the end of a groove that prolongs the areola ofthe vertex mamilla), would be false. Or one would have to modify it by admitting that the section in which there isa blooming groove is short and that the florescence would be entirely areolar??????. Our plant has, by the way, no analogy nor resemblance, with the species of the Aulacothele. Then the unique particularity ofthe thorns, that break after the areola has produced the fruit, and then reject their upper claviforme half!!!! The cephalium appeared to me to be much less obsolete than 1S ordinarily seen in the Aulacothele!? Could it be persisting as in the Melocactus? If so then it would have the right of being part ofthe Melocactus, with which it appears to have great affınity, if one wants to disregard its mamillary body. Should one create an individual type, a new gender, intermediate between the Eumamillaria and the Melocactus, having the body of the first and the florescence of the second? In the difficulty that I find myself it may be that I will resolve my questions with the help of your luminous advice. You have been able to study this plant better than I, you perhaps have some living samples at your disposal. I hope you can answer my doubts. There now, I have again taken much of your time and your patience, dear colleague. For today my letter is long enough if not too long and I will go to another day for its continuation. You would make me very happy if you would not save any of your critiques, and to help me with your advice, as my name is unknown in the world of botany and has no authority when it is compared to yours. In a future letter I will try to approach the thorny subject of the Echinocactus and Cereus.It is there where I will be obliged to confess that the majority of the material that I was able to gather is mainly decayed and does not contain enough reconstructive elements. I will also make it a point to revue and classify my notes, to send you the list of all the species, old and new, that I will have reconstructed. There will be a certain number of species that I will not be able to report upon and of which I will not know their synonyms in Europe. You can well imagine that it is not always easy to recognize the species in our catalogues when they have not been seen in their country and when they are not properly labeled. In addition the market offers them with an endless variety of 7 8 ) 10 MIıSSOURI BOTANICAL copyright reserved GARDEN 8 names. There are some that I will be able to recognize and to place in the proper group, such as the ones from the area of San Luis Potosi, such as the very common Mamillaria group ofthe Macrothelae. These vary alot and could well be the Mamillaria pentacantha or other neighboring species. It would have been necessary to know all the cultivated species in our collections before studying them in Mexico. This is what I did not do. I do not know the large collections of Cacti in France and I have never been to Germany, there I have not regarded the secondary collections as important where the plants are labeled very precisely. It would also be necessary to harvest each day the samples of all the species and then send them to Europe with labels indicating exactly where they come from so that they can be compared later on to establish their variations. All this is very easy in theory, but when one is in the place, with only ones own resources, with very minimal means of transportation, not being able to dismount at every sighting, then the situation is totally different. It has happened to me more than once that the commander of the regiment with whom I marched, told me that Ihad strayed too far or that I had stopped and stayed too far behind. I was frightened more than once by the rattle snakes (Vibora cascavala), that are extremely common, specially in the north of San Luis Potosi up to the Rio Grande. They make the exploration of this rough country, very dangerous. A moment ago I was talking about the species that vary so much, that I am unable to describe them in any other way than by their group. The examples that I would like to mention are the Echinocereus stenogoni, These vary so much or better yet offer such transitions, that I have been made to conclude, that they all are part of one and the same species ( at least allthe ones I saw). I stop for today, my dear colleague. I hope that your occupations will allow you the time to read my prose and to send me a response. If I don’t bore you too much I promise in the future to be a faithful and precise correspondent. While awaiting your future news I pray that you accept my renewed assurances of respect and devotion. Albert Weber Major and physician of the 95th regiment at Auxerre (Lyon) Auxerre December 27, 1867 Because my letter does not leave until the day after tomorrow, I will profit of the time to add a post-script, in order to answer some questions that you have asked me in your correspondence. Firstly I hurry to give you, as you wished, some news of myself and my antecedents! I already gave some information of myself in my second letter (dated in Saltillo), that you may never have received. I was born in 1830, the 17 of May in Wolfisheim close to Strasbourg. I was brought up by my father who is still alive and is a Protestant pastor. At the age of 16 I began my MIıSSOURI 9 10 BOTANICAL copyright reserved GARDEN Studies of medicine at the faculty in Strasbourg, where I became a doctor in December 1852. Immediately after, I joined the health services of the army; I spent the first three years in Paris and in other garrisons in France. At the beginning of 1856 I was sent to Algeria where I stayed until the month of May 1859, time during which I followed the army to Italy and was present in all the great battles at Magenta, Milignano, Solferino. As soon I returned to Paris in the month of August 1859, there was the question of sending an expedition to China, and I asked to be included. We embarked in Brest the following December. We sailed by Teneriffe, the Cape of Good Hope, by Singapore, Hong Kong, Shanghai, Tchefou, Tiensing and went all the way to Peking. The expedition finished there, where I spent more than a year. I returned to France in 186? and was placed in the garrison of Strasbourg. I immediately asked to be included in the expedition that was already in Mexico but my request was not granted until December 1863. I spent the year of 1864 as chief of medicine in the Orizaba military hospital in Cordoba. In 1865 I went to Mexico City and shortly thereafter to San Luis Potosi, from where I wrote you for the first time. From there I traveled to the North as chief of the mobile unit. I sometimes lived in Saltillo and sometimes in Monterey and accompanied several regiments to Matamoros, Mier, or Linares. When the French army began its retreat I followed them down stage by stage with the ambulance until Matehuala, San _ Luis Potosi, Queretaro, Mexico, Puebla, Orizaba and Veracruz. We made long pauses in each one of these cities. I returned to France in Aprıl 1867. From my youth I was given the taste of horticulture and botany by my mother. During my medical studies I studied natural history mainly botany, a little more than was necessary to become a doctor. My botany professors were Mr. Fee and Kirschleger. At this time I became acquainted with Mr. Buchinger who was the librarian of the Horticultural Society in Strasbourg where I frequently went and then became member of its Society. I studied with enthusiasm the flora of Alsace, but my horticultural taste pushed me towards the study of more exotic plants, specially the ones that I saw in the greenhouses and in the gardens. This is the way I began studying the Cacti. It was my fate that half a league from my village of birth, where I spent vacations and where I frequently went, there was a rich land owner with a magnificent greenhouse and a rich botanical library. He was Mr. Saglıs. He was what one might call a rich amateur, who, for ostentation, had a collection of rare plants. He did not know much and for him the value of a plant was only because of its rarity. He was also held in high esteem by the horticultural merchants of Paris, who would have a place for their rare plants. The Rhipsalis Sagliaris was named after him as well as the Echinocactus Sagliaris (hybrogonus). This gentleman honored me with his protection and allowed me his library and his greenhouse. I learned very much about the multiplication of the plants that quickly filled the rooms of the house and its garden. Mr. Saglis, had a beautiful collection of Cacti, for sale, and in which he had a lot of money. He liked them because of there singular nature. He was not interested in having a complete collection but only in having the rare plants. It is with him that I began to know the Cacti. Because I was interested in them I made myself a small collection. I bought the works of Forster, Pfeiffer and Salm that I needed to classify them. This collection had naturally limited proportions. It was a room collection because I had no greenhouse. In the meantime and thanks to the fact the Mr. Saglis threw out the left over I was able to collect some and with Haage and Erfurt and Senke in Leipzig, I amassed 2 to 3 hundred plants. = x AMERE 10 MISSOURI BOTANICAL copyright reserved GARDEN 10 Later on, in 1853, I made the acquaintance in Paris, of another rich amateur, Mr. Andry and also Mr. Labouret. In the collections of Mr. Andry and in the establishment of Mr. Cels, I had the opportunity to know species that were new. However I never had the time to study the plants in a scientific manner. I was only an amateur, I simply wanted to know the other plants ofthe greenhouse, no more no less. Not being home frequently I finished by making a present of my small collection, to one of my parents that had a greenhouse in Strasbourg and who was also an amateur. During my travels to Algeria, Italy, China and Cochinchina I continued to busy myself with botany as a simple pass time. I was marveled at the splendor of the vegetation in Cochinchina that was totally unknown to me. I spent much time and work to get to know this immensely hot greenhouse that was entirely at my disposal. I seriously began the first sketch of the flora of the French Cochinchina, that is to say of the provinces around Saigon but then was recalled to France. My studies were deactivated. During this time, naturally, I completely forgot about the Cacti. It was not until 1863, having asked to go to Mexico, that I again began to occupy myself a little in there study, with what ever facilities I could muster in that land. But Ino longer had a collection with me. The one of Mr. Saglis disappeared following his death, mine nearly stopped to exist. At the moment of my departure for Mexico, I was introduced to your work by Mr.Buchinger. Until then I had only known them by name. I ordered them to be bought in Germany and sent to me. I took the ones of Salm, Labouret and Pfeiffer. At first I attempted to correspond with Mr. Labouret, but had to discontinue, because of his extreme negligence and because one day he simply got rid of all his plants and did not want to be engaged with botany anymore. I had no further news from him nor did I find out what happened to some extremely valuable plants that I sent him from Tehaucan. I then communicated with Mr. Buchinger to find out who the German scholars were with whom I could correspond in regards this specialty. Mr. Buchinger asked Mr. Braun for his opinion and determined that there was n o one in Germany who could give him advice, but then gave me your address. You know the rest and you know the unfavorable circumstances that I have met in order to try to realize my plans. I would have liked to send many beautiful samples to France to be able to study them on my return. But not having anyone to send them to, I had to be satisfied by sending small samples to Mr. Gerard in Strasbourg, of whom I have spoken to you before and who made his greenhouse available for my plants. There has, without a doubt, been a considerable mortality in the plants that I sent him, but only a few species have been completely lost. In his greenhouse at this time there are some beautiful and rare samples, that are difficult to find elsewhere.Among others, about sıxty beautiful Anhalonium, five sulcatum in perfect condition, about thirty prismaticum that measure 19 cms. in diameter; a large quantity of Mamillaria macromeris ( that are found in abundance in certain areas north of Monterey, Matamoros and Mier. It is positively the plant that you described!!); several samples of Pilocereus (or Cereus?) flavispinus whose name I changed to Pil. Doutrelaini because there is already a Cer. flavispinus; some well preserved Pilocereus lateralis: many rare and beautiful Echinocactus in which there are two new and magnificent species, the Echinocereus Gerardi and Sussiori. The first is similar to the electracanthus but quite distinct and the second of the group of Theloidi, having some similarity but yet different from the lophothele, BROT. I had sent a mass of seeds to another amateur from Strasbourg, Mr. Holt, whose care I confided in. I was not mistaken as Mr. Holt was able to cultivate nearly all the MISSOURI BOTANICAL copyright reserved GARDEN 11 specimen from the seeds that I sent him. The Pil. lateralis and Cer. candelabra were the only ones that did not make it. On returning to France, I still have a good quantity of seeds and do not know to whom I will give them. At the Universal Exposition of Paris I saw the Cacti collection of Mr. Pfersdorff, horticulturist in Paris. this collection made me want to see his plants at his greenhouse. In him I found a fanatic amateur, who was nearly ecstatic when I talked to him about the rarities that I had brought home. He immediately wanted to come and see them in Strasbourg. There, I gave him seeds of all the specimen that I had with me. One month ago, during a visit to Paris, I saw that the majority of the seeds had pretty little growths. All ofthese are at your disposal whenever you want them: I imagine that you have a collection and I will send you anything you want, weather it be plants or seeds. From your side I would be happy if you could send me samples of new species that you have described and that we do not have in Europe at least not in France. Naturally I speak of small plants. For example a sample or the seeds of Anhalonium fissuratum would give me great pleasure: also the Mamillaria micromeris, lasiacantha,etc. Cer. Schottii, Cer. etenoides and in general all the Echinocereus. Have you been able to grow the seeds that I sent you from Matamoros? I would be curious to know. Among them there are three species that did not grow here: Pil. lateralis, Cer. Candelabra and Cer. Tetejo ( of the latter I have only one plant). I have to also add that among the seeds that I sent you the name has to be changed on the Cer. Dumortioni to Chiotilla; the name of Echinocereus rinconensis to lophothele. The names of Mamillaria robustispina and glabrata are questionable. The first should be Saltillensis of Poselger and the second is probably new. The following is the list of seeds raised by Mr. Pfersdorff and of which I will be able to send you samples next spring or summer: Anhalonium prismaticum, elongatum, sulcatum. Mamillaria macromeris, Ottonis, scolymoides from Pachuca, scolymoides salinensis cornifera, conoidea, chlorostigma (new species from the Rio Grande, Aulacothele of small dimensions, very small flowers, with ciliate sepals and petals of a white purpuric color, green stigmata), robustispina Saltillensis, Leona (Postelger), glabrata? from La Rinconada, Haagiana, uncinata, calipana Spinocarnea, Karstanii (Poselger), etc. Echinocactus spiralis, longinatus, capricornis, ingens, flovorivens, pilosus, Schurii, cornijerus, electracanthus, var. tetracanthus, lophothele, stenogonus, var. bicolor; horizonthalonius , texensis, hexaidrophorus 4 varieties. Cereus stramineus (from Saltillo), pugioniferus, Chiotilla, edulissimus, Babosso, Toconostle, queretarensis ( new species found in Queretaro and similar to the columnris glabri of Salm) Opuntia stenopetala, Cardona, Camuessa, Toconostle, fulvispina, rastrera, microdasyr, tunicata, Dillenii. The Opuntia Schottii did not grow. Weber, Alb. Translated Manfred Thurmann 7 j 8 9 10 MISSOURI BOTANICAL copyright reserved GARDEN CE, a En En LE 3.

I had made already inquiry from A. Braun and hoped for a long time for news from you. Your comprehensive letter compensated for the waiting. My letter of May 1866 did eet into your hands proper- 1y thoueh late but my last one does not seem to have eotten to you; It was mailed on November 18, 1866, a few days after I had received your letter of October 10.- Thus, one letter of vours and one of mine have been lost. First let me thank you for the detailed notes about your personality ard for your photograph. Only, you do not provide vour forename,and there are so many Weber in the world.One cannot always qualify as doctor or major,etce. I am now already much better acquainted with you, and hope that we may have really gzain- ful botarical exchange thoush you will not be able to observe the Cactı in their habitat, First I owe you a little revenge. Here is my picture, 21 years older than you ! I was born at Frankfurt a/M (on the Main River, E.D.),studied medicine at Heidelberg, Berlin,and Munich, occu- pied myself even as a youngster pssionately with botany,where my association with fellow students A. Braun and W.Schimper were of zreat value, and with the first one at least lead to a friendship for life.- Already in 1832 I emiecrated to the West of America, and after practicing several years in the ®enhtry, and after having travelled all by myself on horseback throush the western territo- ry, I settled in 1835 here in St. Louis as physician, and remained here with few interruptions,includine two trips to bLurope,as doctor. Botany occupies here ny free time,thoush my practice does not per- mitmuch observation of plants in nature,whereas I study the 10 MIıSSOURI . BOTANICAL copyright reserved GARDEN DD coplous material flowine in from friends from distant parts. The study of cacti hegan with Wasshipment from my old friend from Frank- furt F. Lindheimer from Texas,who sent ny a case with Echin.texen- sis, Cer. csaespitosus,Mam. calcarata and some others.The forms nen seen by me delishted me,and I cultivated and studied them. Some years later, my friend and colleague Dr. A.Wislizenus went to New- Mexico and Northern MHexico,and another friend,Dr. Grerg,went with the ru also into northern !lexico; fired on by me, they collected many strange plants, and with special zeal they studied throush the cactus flora; soon afterwards a number of expeditions to deter- 9 mine the houndaries of the new territories and railroad routes to the Pacific Ocean were orsanized by the government; my interest in cacti influenced all botarists who accompanied these expeditions to study the cacti, and, thus, a mass of material was hbrousht to - gether,which all came into my hands. The examination of this indi- gestible omlet showed soon - I really was aware at the very first examination of taxonomic cacti -— how totally insufficient and little and scientific the study of Cacti had been left to gardeners, erowers . I got in contact with prince Salm and found his knowledge also very lacking. The fault was, that the most ardent lovers of castl, as the prince himself, were not botaristss the gardeners even less so; that all of them had no gereral scientific backrround and no points of reference for comparisons. De Candolle is the orly one who presents an exception. Then followed Martius,who however did not much work on them,and Jucrazini,who made the hast scientific examinations,whbb but who as far as I am concerned did not go deep enoueh, Before a continue, let me say, that I have never seen a wild cactus except the locally erowing Opuntia Rafinesauii I All my exa- mination have been made with cultivated or dried specimens, or with 9 10 MıSssoUuRI! - BOTANICAL copyright reserved GARDEN N herbarium specimens, pressed ones I- From this all kinds of imper- fections may be expleined. Further: you and many of my correspondents err'in belleving me to be a cactus fancier. I am this neither more nor less than that I am a friend of all plant families and or kinds, which in one way or another attracted my attention, as e.g. the Isoetes; the Isoetes,the Juncus species, etc. etc. Also, I have no oportunity to cultivate them ard the poor things must stand much mistreatment, .I cultivate them only to the point where they can serve me for observation and study. But I have various friends here, who much want the plants to thing about them otherwise). I received a fine collection of Opuntias from prince Solen,which was taken in for care by a garden enthusiast. They made marveleous progress (planted outside during Summer) ,and many, which never set fruit in Europe, do so excellently (thus the three spe- cies of Nopalea). O0. srandis flowers profusely but did not set fruit; it is probably identical to my Op.stenopetala; my new mexican O.arbo- rescens etc. etc. - the most of the Boundary etc.Cactus I have never had in culture, or, they have died long ago; to the first belone 4 weine Anhalonium fissuratum, Cer, Cer. et yoides etc.; to the latter M,miezos mertsis, lasiacantha ‚etc. Lasiacantha I saw once in flower,micromeris never. By the way, you mav believe me, that I examine a live and bloo- mine cactus today much more exactly than 20 years back, because one does progress, going deeper and deeper. Much of what I published’ 20 or 15 years ago, would be much improved today;sthat is the reason that I em sad, that much or axk almost all of the living material is lost and may not be obtained again so soon. thoueh, once in a while something comes agaln into my hands, thus, during these days, a Sedum from Arizona (Sonoran),however in bad shape; Some thines,specially seeds you shall geladly have. 0 1 2 3 4 5 6. MISSOURI BOTANICAL cm copyright reserved GARDEN Br 4 I return to the theme,mwhich was broken off..All that I could obtain from Haworth to Salen,Pfeiffer,Jucrazini and Labouret I did process hut was little satified with it; I saw soon, that one could Le not build further upon it, and active studies in Nature were needed to start anew to build up; for me all these books ceased to have authority, havinz onlv historical value and eivinz me (sometimes very valuable) direction indicators. You have come to the same conclusion, without wantinge to confess it entirely,or being totally clear about it, Dr. Poselger, with whom I corresponded first,and whom I met personally later (1857) in Berlin and whose not very larze collections and notes I was able to use,was the first to have made extensive ob- servations himself in Mexico, However, he is not a true botarists in the real sense of the word; - only a friend of cacti,thoush he obser- ved carefully. You yourself had now the opertunity to make such obser- vations for an extendet time and with more care and possibly more pre- knowledge? and you used the chance thoroushly. That you consider it your duty to present to the scientific world the lesson of your studies,even if these could not be as all-encompassing as vou may have wished, I can only praise.And I eladly will be helpful to you as far as my limited knowledge nermits. What you say about the careless definition of the home land,or, even more the specific habitat,is entirely correct andvexed me often; In America calidiore,- in NovaHispania - Mexico - etc.etc.,or sometimes U OÖ very exacting,e.g. near'Harienda San Antonio or such,thoush there are hundreds of such haciendas. I made all my correspondents awares of this You are also correct about popular names,thoush these provide only a very small help,which,however, should not be neglected. Dr. Seemann in London broueht this up lone ago; Dr. Gresg was very conscientious ahout ah 4 it.- The note about the recoenized relation of Ech.Williamsii'’and Anhalonium is interestine enoueh, hat von say about synomyns is undonbt. 9 10 MISSOURI j BOTANICAL copyright reserved GARDEN er ee) edly correctz;onl\ly you should not express vourself,that 0O.Dillenii be the mexican form of O0. Engelmannii,but rather 0. Engelm which was only described 16 vears ago, is the northern form ofthe long known 0. Dillenii. I alıwavs believed somethine like that.And a lot of the newer northern species are without donbt lone-known mexicans, specially in the genus Opuntia; what I susgested alreadv in part,e.g. 0. Wrishtii is O.Kleiniae; O.arborescens is O0. stellata etc. What you say about the deficient institution of the "commission scientifique" surprise me ver much. This "Bourjeand" should probably vi be Bourgean, who tradet in Spain, Africa,and last in Northwest Amerika If so, then he is a ver industrious and good collector,but obviously not a botanist. What you sav about Deraisne,an old friend of minre,, dumbfounded me and made me wonder..I did not expect anything likethis- but, of course, the the parisian learned institutions are an evil 1 school, tion is not an easy one for the entire botany and is being answered according to different viewpoints very differently.Thus Benthen and Hooker contract much in their new works; others multiply the zenera indecently - the same as found in the species. I am not satisfaied with tne division of the Sacki. What this question concerns,it seems to me the duty of the honest inquirer,to study the groups which offer thenselves in nature,to proof their ancestry, to look for differences from other eroups,and to weieh the value of these differences,and,then, finally to decide what he wants to join torether in genus groupings or must,i.e. what Nature herself deliniates. But I am forced to arsin brine to vonr attention, that unfortunately most writers about cactiwere not enoueh botarists to be able to distinmuish with a more zeneral ard freer view; must however still conced, that even good hotarists have created _ 0 1 2 3 4 5 6 .7 8 10 MıssoURI . BOTANICAL cm copyright reserved GARDEN ? L bad cactus genera,e.g. Zuccarini the genus Echinopsis ‚which accor- dine to my opinion belones unconditionally to Cereus. As vou remark correctly,as such natural zroups Opuntia ard Peireskia are apparent,. ( that you did not see none of the latter,surprises me,because De Candolle pictures such beautiful,mexican Peireskias). For the charac- ter of Opuntias, which is specially in the seeds ‚to which I believe to be the first to to attract attention,several striking vegetative variations can be added;such as the folia subulata decidua (awl-sha- ped,deciduous leaves,Ek.D.),and then the aculei et setae hactatae (‘ spines and bristle-like hair the latter differentiate immediately the Peireskias with opuntia-like leaves,even when the flowers are missing. This character of the spines is strangely constant;I find it also in the family of L saceae,imhere all species (at least as far as I know them) are provided with stiff, innumerable short(broad,less sharp,and not really bent backwards) little hooks. The seeds of the Peireskias, of which I had occasion to examine several (from Cuba and Sonth America),are entirely different from Opuntia seeds; black, similar to the other cacti,with large,leaf- like cotvledons, so that as far as seeds are concerned, the Opuntia stands entirely alone. I would rather divide the entire family into accordine to the seeds 2 large eroupenhere the Opuntias would stand opposite all the others. If one wanted to separate Nopalea and Opuntia one would have also se- parate Xenopuntia_ and also probably Cylindropuntia.But I world rather leave the zenus united, — u eg A) cs Cactus moniliformis is, I'd rather completely defer,until the plant will some time be found asain and carefully examined. If the illustration of Plumier is correct,then I Ao not doubt in the least, that it is a genuine Cereus.- I would like to stick to the difference in the cotyledon,which I was the first to find,thougsh it is not present quite absolutely,as we find the same with the Corifers,where this cha- MISSOURI . BOTANICAL copyright reserved GARDEN Tr character has been honored for a 1lonh time. What you say about the position of the flower of O.clavata_ is correct,but the fact of the position has very little mearing,nothing certain, hardly specific. Yes, it may ewemrbe,that the totally ripe fruit throws off the remains of the flower finally, as you mention this for Schottii. If Opuntia already points to the fact,that the exterior form is not necessarly connected to the formation of flower and fruit,this he- comes even much more evident with Rhipsalis ;- Who would join Rhip- salis pentasona and pachyptera with out seeinge the flower. I do not know if Ffeiffera belones to this; the dried flower of your CGereus puetioriferuss, and what you told me earlier ahont this species, Seens to put it to Rhipsalis. If this is so, then we have a species with strong spines,whereas all other have hardly an indication of spines. But why not ? This would be the Rhipsalis cereacea.How is the fruit ? Is it too spiny $ semi-transparent,as with the true Rhipsales_? I have made fine studies about the placenta formation of Rhipsalis,which busszed all botanists ‚who worked on this,from Gartner and De Candolle until out time. Unfortunately,such examinations can only be made with live specimens,- How is the fruit of Pfeiffera ? I assume also spiny, not like Rhipsalis !- with Cereus the exterior form takes on all possible nuances, and he,who has studied a number of cerii finds, that there is no charac- teristic in these forms. From ceylindrically thin C,. tuberosus to ball-shaped pectigarus etc. one finds all gradations,while the flowers are all those of the Cerei echinocerii are,resembline each other to cause confusion; and that is only a small group. Thus the transition from the two-winzeed Phyllocacti to the three-edered Cerei is entirely non-apparent. But even the construction of the flower is not decisive By here, the oblique and the straieht (regular) flowering Cerei appear 9 10 MISSOURI . BOTANICAL copyright reserved GARDEN e in different sections; but again those with a separated corona of the stamens and those with staminiae eradatuis odoata I I pointed to “ this in an article in the St. Louis transactions, but spoke only in an indicating way. When I get a flowering or fruiting cactus now,it will be exan- ined in all its parts,;,including pollen,funiculumyovulum,embryo,etc, but I have to assemble first more material, before permitting myself to draw zeneral results. I do not agree, that you could be asked to reform the entire science of Cacti,even thoush such a reformation would be most desi- rable. Obviously specific question will come up, which you will have about to answer. e.8g. Mam.micromeris specially. In general you may stick to the common classification if you do not consider yourself sufficiently capable to emerge as reforner. Assin, group your species,without giving the groups at this time zenuric names; look for prime differences of these rroups,and if these are sufficiently cutting,then name the group a genus. I feel howO ever that you are inclined’ to state much too many genera; as you know, I see only few genera within the cacti; but I do not know enoush spe- cies by a long sight in all their parts,to make a final decision.- Again, when we find such strikingly different forms even in small,well defined groups (as Echinocereus), why not in the largest group, where enough large transitions are at hand from Cereus gisanteus to C, reduc- tus : First the flower and the fruit I But even there, as already said,. exist so many differences and transitions,that one must get confused never by it. You will find, that in most cases the "groups" may|be named ge- nera or even tribes, but much rather sections. Compare sometimes the genus Euphorbia ‚which was supposed to be split into dozens of genera, and yet all clear (thinking) botanrists agcree,that the Cereus-like Euphorbia antiquorum etce.and the small low-l1ying E. ERBE 8 9 10 MISSOURI . BOTANICAL copyright reserved GARDEN en and the hundred different forms belong all to one genus.- I follow your "fasson au revue" and must say richt away,that I liked Salem's large twies (? 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 growine together (deformation ? E.D.) of the floweringe organs,which is common in all parts of cactus. What you say abou germen inclusum say is in part new to me. One can only iudge about it if one has disected these cacti,and that 1s hardly jermitted nKuxzikte with cultivated specimens and can be doen only where they grow wild in quantity. It is necessary to make longitudinal cuts (not erosscuts). Get a few loneitudinal cuts throush flowers of Mam- millaria, ovary and surrounding parts,of such species,which are de - 2 En u Du finitly supposed to be immersae, this immersion is obviously nothing else than a erowine torether of cells,which as just remarked, belongs ts1 to the nature of the entire family - or at least more or less. One difference,which you do not mention in your letter,seems important to me - Zuccarini was’ the first to sall attention to if, it Is that 12 of the Mamwillaria lactifluae and M. aquosae; this seens to me a fine ee - 4. grouping; to the first belongs of mine only Heyderi (= applanata, = hemispherica ) to which as forms are to be added micrantha,echinacea and others. These Cactifluae seem to me to have ovarium immersum, if there is such a thing,which you doubt. Renew the investigatlon !! I do know,that the upper part of the ovary protrudes,and that in cutting off the flower x opens the tavity of the ovarium,but a part of the ovary seems to be inserted into the body of the plant - this I believe. ED I assumed that Man Yllarıa \adescura C*) (cannot decipher, but Kner 4 could be &alcarata. E.D.) presents this phenomenon,„white the E.M.. had aquatica (? E.D.)/an ov. emersum, MISSOURI . BOTANICAL copyright reserved GARDEN En 3 - 10- That, however, this character is not of generic importance, I be- lieve completely as do you. with Anislorium the ovarium is not only not immersum, but stands, as I have shom on top of the young mammilla. The same is the case with the Echinocacti theloidei and probably with Mam.micromeris, when properly seen. I miself had only thin specimens of this plant for examination,and had for this reason ‚as you see for the Boundary cacti,.leave these questions undecided. 1 should remark here, that I had occasion to examine a Ech.theloideus (E.Simpsoni),the most northern as it rrows imto Utah and Colorado, in flower; I* has much similarity in flower with Anbalonrium, showing only spines but lacking the tuft - but the tuft doesn 07 have the minutest importarce for me, which you attribute 'to it; it 1s a secondary appearance; more or less hair on the areole, more or less compressed in the flower- inz areoles.-„that is all I- Now this E.Simpsoni, which without De flower looks almost entirely like a Mamfillaria,and seeds Aike’M micromeris,and seeds and fruit like the sharp-edged,no less than warty Ech.intertextus (Boundary Rep) !

In the meantime,thus, to Anhaloniun ‚if ANA AOTL UM not Anhalonrium it remains a Markillaria,wrich I do not doubt any further,: So, you studied A.sulcatum and cultivated it yourself,and thus you know, that it is quite different from my fissuratum_ !

I cannot tell you anythingz about MelocactusI never was able to examine it sufficiently. Why is that not done in the botarical'gar- den of Martinique ?The matter would be easy toto get to the bottom. When I get time I want to raise a CubanCephalimwag.But it is very likely that Monville is correct.-When there are no tubercula as with Filocereus,but where they have converged into ribs there cannot be a possibllity of conaxillary inflorescence.There should be mentios means ned that taken verbatim axillary|"sittinge in the axis of leaves" that however the mamilla is not a leaf but a protruding part of the stem.on which the leaf (if present or indicates) sits.

If you do not want to preserve the name,which I have given,despite the fact that it 1s the first which describes the group exactly, you follow a general custom. One could say that Anlacothele could demand wu priority,though de iptive enoush,it does not describe the spicies as does my cn (vide Salm). The law or right of priority has by now been adopted by all botanists,that, as you know, a lot of other medern names had to be eliminated (e.g. a lot of "Lamarck"). Anlacothele hax another meaning with Salen ‚would it have denoted the same, I would have adopted the name.- When a name is "impropre" it ri MISSOURI . BOTANICAL copyright reserved GARDEN B 2 is not valid;otherwise Lamarck would have been riecht a hundred times azsinst Linneus. But I. showed you, that that the name is not "impro- pre". However Anlacothele has still the riecht of priority.- What you say about the areoles and the elonpation and belonging together,is probably correct,morpholorically,and if I separated the two areoles, I considered more the appearance than the substance. As I have shom, there are Echinocactus,which have the same wrinkle; in many it is at least indicated by enfoldinge of the areole. Now, I want to show you still another difference of these plants; with the ones referred to above, the flower emerres in the midst of a full areole,but with Cereus it pushes throush the epidermis of the plant, which it explodes and tears,not throush a real areole. Most likely it is the same with MamAillaria. If it is thus with all Cerili, %“ I do not know.- Observe this, if you have the oportunity to see flow- ering plants. You know, that Poselger counts the Coryphantae with the Echi- nocacti, thus his E.lophotwde etc.etc.,wüich I believe are Coryphan- tae. He was the “first, who called these plants Marwillariae (though then unknom to me);he considered them Echinocacti,standing near the theloideds.- but as said above,the orly E.theloidek, which I know, has flowers and frult standing on top of mammillae, not in the areole wnich is elongated into a furrow nor the basis of the manmrfilla, and is therefore similar to Anhaldntum The seeds are not definite points of reference, one finds as far as I know, with Cereus plants always more or less hard seeds: specially hard and bumby with Echinocereus; ditto with Echinocactus, softer or harder,alsmost (not always) black, smooth,with indentations and protuberances;- With Mamillariae they are often lifeter-colored, but even true Mamillariae,e.e. pusilla,have black,hard-coated seeds. The seeds of Coryphanta are all (?) brown and thin-coated,thus diffe- rent from Echinocactus MISSOURI , BOTANICAL copyright reserved GARDEN A 14 “ Once more about species. From indications in your letter it is apparent, that you do not agree with the separation and deter- mination of the zarden species of our books; however,you do not seem to have the self-confidence to attack the subject. Do so, and even destroy my own ‚when they appear incorrect. I put much too much weiseht on spine formation 15 years ago. Nobody can form a valid judgement about the boundaries of species,but who has seen himself in their homeland all the transitions. With as many species it will aleays be difficult to establish limits,and I doubt not in the least that of garden and book species will prove artificial throush du- bious observation of Nature in the homeland. Talk about it without hesitation. A note again in one spot of your letter,you mention the tuft, Cephalium,and warn again, not to give welilsht,or not much weiesht to it.- What you mean,when you say that with Pilocereus the flower sits on the tip of the mamilla,is not clear to me. If one can at all talk about a mammilla,then the flower of all Cereus stands close by the spine-bundle; but once more, it does not break from a pre- pared,more or less woolly areole, but pushes throush the epidernis. But with the premise, that your observation of M.micromeris is correct,namely that the flower of Ech,.theloideis and Anhalonium really stands upon the mamilla than the plant would be related to these; and would have to be named either a Änhalonrium with strange formation of spines and strange seeds; or Echinocactus theleideus but with a smocoth Fruit. It is certainly a strange plant but Z would waite before I would create a special genus. I would join it as abnormal to one or the other genus. Such abnormal forms we find everywhere in Nature, thoush we do not have permission to consider them as proper types, which may not be separated. MISSOURI . BOTANICAL copyright reserved GARDEN By the way, as I said already above ‚the Echinocacti theloidel do not please me at all, and the very close relationship of my Itz E. intertextus and E. Simpson force me to let go of this rroup which is based only on- appearance. I believe, I spoke earlier about the inadmissibility of the ex- pression "infloresence axillaire", I would not like to see it used. Axillary in botany stamds for: emerginge from the leaf axil,and the axillae of the Mamillariae are not leaf=axils.- That is the problem with describers of cacti,that they are not botanrists,and both,there- fore, do not understand each other. I won't accept your assurance, that you want to play safe behind my authority (abritez dernriere votre nom). You do too little honor to yourself and too much to me. It’s not authority but correct obser- vation of Nature,which counts,and which must be your support. As I | authority told you already, I have learned to mistrust everywhere in my stu- dies,but specially so in the cacti. If the cacti were not "erikittet in Mexico,as you call it,then there is no danger to trust wrong labels,which is a danger for every- body even with the best of collections. Desides, you are richt to consider the necessity to pay attention to the historical part,which has happened so far; even thoush the authority of the predecessors must not lead to contradiction,we must however always know and give credit,ıwhat they have accomplished. As mentioned above,it is thus retracted not permissible to change your name. Thus, I havelmy name Man. given applanatalin üncertainty and innocenge,in order to place the older M.Heyderi. As you combine several nominal species,the oldest name of the species must remain,;even if not entirely fittine or descrip- tive, What you say about variations pleases me much - this forces you to search for the limits and characteristics of the true species 6. 9 10 MISSOURI , BOTANICAL copyright reserved GARDEN and to determine them. Und I have been convinced a lonr time, that thereby flower and fruit are of upmost importance . I give ever less weight to the orsans of veszetation,the longer I study these plants, Be on guard setting up new species if you can find old ones,.if you can connect your plant; considering what you know in general about the variabllity of this plamt, even if not everything fits exactly. Should not N. pentacantpa and " ea autresfsp picies voisins" ard also your St.Lublig® Potosi plant belonge all tosether, Instead of settine up a new species,you would gain the merit of jointhng seve- ral untenable garden varieties,and, thus, »brinz them Shoser to our systematic of Nature. Your name "edulissimus" is not botarical and must be changed; may-be sapida or deliciosus, You are very kind to offer me seeds and young plants. For the first and for fruit I am most thankful; they are valuable for studies for me; butt I cannot cultivate plants,as I told you atready. By the way, Il shall come myself to Europe durine the Summer,and even iflI cannot look you up myself,I will without doubt visit Strasbure and faris and to see your things there and may be able to confer with vou.. Some few Echinocerii, which I cultivated here,you shall zladly have, and I enclosed seeds of some "whithegetrinto>-th& southwestern United States.which give me much pleasure to share with youse.e. such of Cereus gisanteus. I myself sowed some of your seeds’ and a few germi- nated,but perished due to lack of further care. That you found M.macromeris there in the lowlands,is strange enough; thus,it has a wider distributiemm than these plants have con- monly; thoush I have already seen plants oß Nuttalli from Rbo Grande.. Did you gather also herbarium specimens ‚„flowers,fruits, spine-bundles,or, even better, entire sections of plants,and what has hanpened to them 7° Still’ mores :Admonish your friends,who cultivate your orieinal!' MISSOURI . BOTANICAL copyright reserved GARDEN specimens,to be sure to preserve those,which have died,as they are of sienificant value,and should not zet lost, To me,they are almost as worthwhile as livine plants, specially if they have flowers and fruits. Likewise it is desirable to study flowers,which should de- velop,and to preserve these, if possible, for the herbarium. This brinses to my mind,does your Opuntia stenopetala have also such’ interesting shoots and leaves ?“"For Op. erandis, cultivated here, they aredeep brorm-red,most strikine. As I told you, I will leave St. Louis in the Spring and spend perhaps a year in Europe. If however you should answer me soon,then your letter will meet me still here..

L can tell you now, that I intend ke during February to Marseilles and Mont- pellier,and that I will by end of February go to Paris. If you could see us at one of these placesyor, if I could look you up without too much” trouble, then this would be ver, dear to me and,hopefully, fa- vorable for our common scientific studies. On Septenber 15 I wrote to Mr. Bfichinger, and told him in a ge- neral way, that I hoped to see you this year in France,and, also, gave him addresses in Florence and Rome,but did not hear anything further from him or you. It seems, that our correspondence suffers as much in Europe as in Amerißa ! As I do not know, if you are still at Auxinfe, I again mail this sheet to Mr. Büchinger,who, without doubt, is better informed about your where-abouts than I, with the request, to forward it as soon as possible to you, I do have your letter of February 25 in front of nme, but cannot now go into the specifics. I shared it at the time with Dr.Poseleer in Berlin;zwho'se name is surely familiar to you,and who takes very much interest in your work and examinations,and who spoke of gettine In eontaet witn you. Did he do 80? There is such a long time since my last letteröto you (Jan. 27, 1868) and your answer,and the probability of a meeting is so rreat, that I do not want to persue the scientific content of your letter. All that can be discussed much better in person, Only that: Your expressed viewpoint: "de toucher le moins possible aux divisions actuellement admises" (to touch the least possible 6 .7 10 MIıSSOURI . BOTANICAL copyright reserved GARDEN actual division? I can only agree and completely share, because on- ly after studying the fundamentals thoroushly, should a reform job be undertaken,. I would only like to introduce one limitation, that I cannot separate from Cereus neither Phyllocactus,nor Echinocereus TR N R nor Pilocereus nor Echinopsis, and equally "Y@MQ from Opuntia. k Bentham and Hooker's remarkable genera unfortunately give proof in the classification of ecacti, of too little study An a difficult ques- tion,- I must add, that I have returned to to a number of criteria, which I considered very important formerly;e.g. the separation of the stamens of many cerei and Phyllocacti and Echinopsis into two groupds,. of which the upper and outer ones are Sseparated from the other,forming a corora,as e.g. with Cereus speciosissimus,nycticellus,Echinopsis Eyeres a.s.o the case is, is not closely interconnected with other erowth and floweringe characteristics as I had believed earlier;: it re- mains important enough for a subgroup, but can not be used for a major division of the very large zenus Cereus. I must always come back, what I have expressed so often, that first an exact study of a large nun- ber of cacti,their flowers and fruit,„ can hetprus toward an understan- dinge of thia Alfficult family. And I höpe,: that your efforts An Me - x1co will contribute substantially, to solve many a difficulty, and am elad to be able to presnt questions to you in person about various pvolnts, I occupied myself in Naples,where I spent 2 months, besides the plentifully represented Conifers,qguite much with Opuntias. Nb. Around New Year there flowers masnificently Taxodium mucronatum, the Cypress of Chapoultepec - You did see this famous tree - Did you make notes about it ? Collected specimens ? And did you observe other Conrifers ? As you know, all around the Mediterranian Opuntia ficus indica are gsrown’and has gone wild. In Naples it is common on the markets, mostly an orange-yellow form with yellow flesh,rarely with lisht-yel- low-greenish (aprle-like) flesh, and most rarely a purple-red’ one.- MISSOURI i BOTANICAL copyright reserved GARDEN Could this be the source-form ? Is this variety found in Mexico ? And is the plant there also almost without spines ? A very spiny form of it, is, I believe, O0. amyclaea. Generally, I daily lose ever more the respect for spines as species characteristics, and in a whole set of formässwhich are called Dillenii, tuna,homick,pseudotuna, glau- cophylla etc, seem to me - according to the fruits - to belong toge- ther. Flowers and’ fruits must be studied)Jand I hope you have lots of material and observations broueht along from over in Mexico, The difficulties in our gardens are multiplied so much by circum - stances,because the plants have almost never any fruit,and,possibly,. even worse, that they are being propagated throueh cuttines,thus only a single form,presenting a single individual, not a species I But, you know all this yourself just as well. Your letter is so rich on observations and remarks, tböhataätikill be of hishest interest to me, to read throush it again in your presence.

I remember, that you complained, that he did not answer; I almost believe,that the letters were lost and ’ Ne he ch that I had the same experience. How can this be. He dia not know , that you were in Paris,and, I believe, wrote to Auxenne. I had sent him of your seeds and he had received more from you. The seeds gzerminated well; and he also gerew some of my Arizona seeds. But, what he mentions as connections in western North Americ ’ & nen A, does not seem to be worth much.

Will you refım infthe Invalide home ? IT have not seen much of cacti,which would be of rreater interest. I saw the Opuntia "vestita"(the samebßf which I saw the fruit in Antibes) in flower and fruit;the first white and a most delicate violet-red. What interested me however most was Cereus virens ‚which I saw se- veral times in flowerbnd which I could examine.The flower is the more strange,as it has all the characteristics ‚which point to the_Piloce- reus flower,with the same mass of stamens,long pistil,rolled-in petals and senals,and after fading,the nectarium hollow,closed below( but not more and hardly as much as with Echinspaechttssimus in Paris)etc.Besi- Aesharäly a sien of sepulis ovarii,4 - 5 extremely small bristle-for- minz sepila,which on drying cannot be found any more,and blooms nieshts. Veretatively also absolutely nothing, which would identify the plant as a Pilocereus;smay-be somewhat similar to P.fossulatus, but with fe- wer,shorter,soon disappearing hair-spines. Do observe Cartisii,which must be very similar;I do not see it here.- I don't believe, I told you, that I saw at Dr. Poselger the ori- ginel of his P, celsii At first sieht it does dumbfound one;he found it in the brush of P.senili (long and short-hairy forms mixed tore- ther)and thousht to note a difference only after returning to Berlin.

I was very sad receivine several times the news some time back, that you had perished in the war, and am delishted that it proved to be in error, ZI occupied myself here and there with cacti,and could, if only I could get to it, publish a strong addition to my prior labours; but much too much remains to be studiedü,while, as you know best, we can work only with fragments. I have gathered a lot of seeds for you,hoping, that you would still be interested, enclose howeVer today those, which I have receivedfrom San Dieso and the southern tip of the state Califorria. Hopefully a lot more nice material will come from there, now, that I have a correspondend. The one is the old Mamillaria Goodridse Scheer,which seems to be frequent there. I took the fruit from a living plant sent to me by mail. This species and M\Grahami are very close. Ihe other large seed is from my Opuntia prolifera , Dut, therefore the seeds seem to be spoiled and not able to germinate from a spoiled fruit. They were unknown to me, confirmine anew the strange character of the seeds of Opuntia cylindrica , and at the same time different from all know to mes I believe they are also the largest of the ceylindrical Opuntias.

But, all that is past, and in your letter you show yourself entirely as the old one.

Did you receive the few seeds,which I sent to you 1 - 2 years ago throuseh Pfersdorff ? What you tell me about germination of old cactus seed at your colleague at Belleville,was of much interest to me and I will try to gather seeds for him; No, Mam.phellosp. is no place in cultivation. Your desire to obtain the entire cactus literature is quite praiseworthy and a mishty step in the preparation of a study in depth. As far as I could, I did the same, though literary help is not easi- 1y obtainable in this out of the way place „ In Europe however I did copy a lot. What I could not do,and what I would have 1liked to do,you may be able to accomplish,namely to have all illustrations, which you cannot obtain yourself,coried. Barmann Plumier I owm myself - what you tell me about it,is ı er interesting,and the more so, as I have a friend,who is a reoloeist in San Domingo, and who is interested in cacti, so that he has already made a small collection for me,when he passed throush the peninsula j- * of southern California,and carried it alonz on his mula ina small Dr cClgar box.

Since we saw each other, I have also worked on'the genus Yucca ard obtsined very nice results. I enclose seeds of two rare, sonuth- californian Yıccas for our celleague Martel (we have near here also a small town of 12,000 - 13,000 peorple,Belleville I ‚which is fre - auently called " the friendly neishbor small city" by the Germans). The thin seeds are Yucca Whipplei,which is already in Europe, the thick ones belong to my Y.brevifolia, the tree of the California desert,which, I believe, is still unknown in Europe. What kind of means does Mr. Martel employ to make old seeds ger- minate, hot water,chlorine,or what ? We live quietly on. I reduce my practice,make trips more often, make them to observe, more literary labors,while my only son,who re- turned 4 years ago from his europasan studies, came home and created a strong practice already.

I see that Opuntia Rafinesauii is being much cultivated in Europe. It is the most common in the North to New England and in the West to the Rocky Mountains. Opuntia vulearis, as I understand it, reaches all the way to New Jersey; I found it frequentiy in North Carolina in Fall,and always very charac- teristic. Does the cultivated vulearis Aandrthe wild-growing (actually: "sone wild") italica always correspond with yatlıa the typical vulgaris ? Are there botanists in Europe, who buy the dried plants ? Local plants can be had (Missouri) very cheap; more expensive,North Cali- forniablants,of which a collection of 200 - 300 numbers of rare and new items is beine offered; fine specimens, Your old friend G.

You see this from the thick letter-package,which I mail in reply. First, I should wait for your promised letter, but as I have so much material, I promise a seconf letter. First, I return to you the seeds of Opuntia with thanks inclu- dine notes. The seed is imperfect,without embryo,and with very soft coating; it must have been quite young. The shape may a been al - ready that of the ripe seed, and needs further observation, but not the base for definitive concelusions. The plant itself I had in my section of Ovatae, of which I know only O0 vestita and - don’t laugsh - O0. eylindrica „ Both have almost the same seeds. Do you know them, or shall I send you some ?. The Ovatae join the Clavatae as subdivision of Cylindraceae;- The first south-american, the latter north-american and all the way To our territory, That the so-called Echinocacti are thus geosraphically sepa- Nuslisensneschebehenin nd | | rated, you know. Are there not Echinocacti in Southamerica ? Those, which T desienate as Rhodostigma are a separate dAivision,which be - long rather more with Echinocereus to Cereus. What is your opinion ? Likewise is Gymnosabucii.... a northern tribe,which lines also up with Cereus, The southamerican Cerei constitute their own line of forms, which I do not understand well due to lack of material; I called them VV Eulychaia after Philippi,who'se original EZ examined at Kew.

I knew well the Galapyastı,accordine to the descrip=- , men een tion; this is reprinted in Welpu's Repertorium vo. 2 2.354 1843, from which I copied it into my 1listingevof cacti.But for the dra - wine and deseription I thank very much, as thev were unknom to me, and, thus, I could not determine my plant from Agassiz. Now, I have no doubt any more, and can even clear up your statement. I do possess this O0. galapageia from Agassiz and it is alive, and I hope to be able in about a month to send you a good member, when there is no more fear of frost. The very large,woolly (the wool does not shed) areoles with thin,bristliy spines are very characte - ristic. I enclose in this letter a spine-bundle from old and younger members, - The Opuntia, which I mentioned in my previous letter, it ano- ther one; and the one grom by Nebon & Mrs. Yard. Pl. which we exa- mined together in 1868,and, of which I took a few spine-bundles along, as well as my Cabauch & Agassiz are identical. I call it O.myriacantha (is'nt it similar to spinosissima 7? ) Our plant is weakly and I do not know, if I can send you a piece. We will see. I enclose an entire spine-bundle of a wegk member. Thus I have from this farthest protruding outpost in the Faci - # fic Ocean 3 cacti,that Cereus and those two Opuntias. I want to mention, that, when I heard that Agassiz wanted to establish a station on the Galapagos Islands, I wröb&eetoohimtandihbroueht to his attention the cacti of this geographically and plant-eeorraphi- cally so protruding group, as I had specially Nebon's plant in mind. ine-bundles us I want to remark,that with O.myriacantha the s stand much closer together than with the others,and that the areoles are much smaller; the members however, thinner and smaller. Galapareia has very thick menbers,which become soon cylindrical. u 8 MISSOURI . BOTANICAL copyright reserved GARDEN en 3 in will be very elad, to hear more about Ech.Californricus;s 1 20 belleve to know Just about all the cact# of our California, but it may come from the Califorria peninsula,which, as I know from Gabb, contains still undescribed treasures of cacti. I will be very elad to receive also fruits and spine-bundles and a real description, and I will be much obliged to you. How does it stand with the angle of the perianth ? I this known, what gross mistakes are beine made by travellinz collectore and seed-merchants. No, I do not possess the works of Lemoine; he had promised them to me if I would“send him mine. This I did,but he excused himself, that his were not to be had. That I did not answer him ard that I do not maintain a good memory of him, is natural,but, that he pe- . that rished so miserably, makes me sogry; I did not know it. Don't you drye flowering cacti, which you examine ? Drawines are very geood - but dried specimens often provide details, which one En Ad did not observe in drawing. Your remarks about the pre-opening of the Cereus flowers may be correct. By the way, I found #kksxzwith all our Cereus, which I see flowering, also with spinosissimus, this statement verified. Thank you Ior pringine At to my attention, I shall watch for it At the rare opportunity, which we have here - you too, please,do the same. Now, if O.frutecens makes an exception to the day-blooming Opun- ® tlas,then thst is just an exception,which must certainly be confir- & med- it does not eliminate the fact, that, as far as I know, all other Opuntias open only during the noon-hour and fully open only E 3 in älrest sunlicsht, All remarks and corrections will as ever be most welcome. I was most interested to hear, that you too have been occupied with the study of Agavae. I find, that my small dissertation has 1 en 2 ) un raised much interest,and I received responses from Beleium and spe- 6) yo er a 1 er o S In cially from England frquentiy. The group with the c« 6 . MISSOURI j BOTANICAL copyright reserved GARDEN .. li jr \) almost ear-like SSSUrE.. interests me much; was hardly knom to me; My A. Newbergei seens to belong to this. Be sure, to have a photograph made of every flowering agave,which can be put with the drawing. The inflorescense of’ Verschaffeltii will also be quite interesting, as will dried flowers of it. Are no attempts of Betrrinätsobnen made ? When the stiegma opens, 2 - 4 days after the opening of the anthers, and exudes a large drop,then is the right time. In this juice the pollen tube develops very well, as I have seen often and still to - day wath the microseope . We have just now Agave Shawilin flower. I made drawings of the flower and the various steps of development;- From the ovaries to the tip of the pistil they are more than 6" long when fully developed. Only on the Uth day occurs the full development of the stigma and, thus the possibility for fertilization; at least with this plant and at this time of the year. Q Haneing ears (inflorescenses) of Azavae I have also seen in Berlin. Dried flowers of Agavae and descriptions will always be most welcome,although they change in drying even more then flowers of cac- is, Has this Arave consideranti [Species name illegible,E.D.) been described” "Then the english name would come too late. Publication with desceription-in a scientific opus,Journal, etc. secures priority. Publication in catalogues does not work. Is it really an Agave ? Are the flowers known ? What you tell me about Lechusruilla is quite tr interesting and I will not fail to lock for information. Amole 1s also made from Yucca species and I doubt if Saponins is really in- volved. Research about our Yucca had a negetive result,and your per- centage of 51% saponin is, as I think, just about imposkible.

I was too much invilved in other work to get to it, Many thanks for the interesting notes,which you sent along. I return drawinges and photographs. Further, I send one of these days a small case of live cactis: Opuntia Kleiniae (comes from prince Salen collection,and bloomed’ here several times,but produced no fruit. O0. galapageia and O.myriacantha n sp from Asassiz 1%72 brousht from the Gallapaeos Islands.- Op. microdasys which you wanted to have (comes from Salen), O.rufida similar to that one, I received it from Bexäso( North Mexico) ,have not seen it flower,seems to me identical to the one so called, which I have seen in dried state only; is certainly very close to micro - dasys. Cereus setisrinus (Dr.Weber changed this to longispinus,E.D.) has never flowered for me,but throush erafting and good culture friendg make it bloom well; it is an offspring of old plants,which I received 24 years ago,.. Also I just receive a small shipment from Arizona,and, in the hope to be able to obtain more of it, I send you the only specimen ever brouseht into cultivation of Echinocactus polycephalus as well as some flowers (with their wool :stmilar to ingens) „ Also, ver; young Echinocactus,which I got from E.Johnson from southern Utah. Opuntia arborescens flowered here freanuently,and 2 years ago I saw it by the many thoudands in southern Colorado; in September, with their yellow fruits they look like flowering bushes. Eecause I thousht nobody was interested in the plant, I did not take any fruit with me. I cut a section off here,which as with Kleiniae, rotted when I wanted to dry it. These cylindrical Opuntiae rot or 10 MISSOURI . BOTANICAL copyright reserved GARDEN dry out very easily, and I find it best,to lay them on top of sand, where they set roots; if one sticks them into sand, they mostly rot. And then, you will enjoy a Mam.micromeris,which I received from West texas. You willfing several others in the little case. All plants are labelled and a list lies in the case. Now about the illustrations and notes you sent. Yes, E.califor- nicus is different from any other seen by me ; I doubt, that it is from California. As you remark correctly, it seems to stand most close- ly to Emoryi, of which I have also only incomplete material... A geolo- . .‚gist, who traversed Lower California,brousht me notes and a few spines of cacti there; one of them A attributed to Emoryi_ ‚which could how - ever be this one. The material is too incomplete to pubflish anything, if one does not want to act like Scheer and Seeman's Bot. Herald, which I om. There are 2 spine-bundles with the pattern shown alongside; the first,with few spines,nmy witness found rarely,only on a mountain; the second, however,all throush the pen- % \ insula,everywhere,. It has about 11 Ech. Emonft Eye eywysulae Var. Nechpiyus mper strong rim-spines,the lowest of the 4 PT: middle ones is very strong and colored. Flowers reddish, the plant to 5 feet tall; has oval, scaly fruit. N Brousht only one spine-bundle. It is mean, if one has ch poor material ! E.Pottsii is totally unknown to me,thoush I had one from Wislizenus collection.from Chihua- hua,which I believed to be it,which, however, did not live long. Sad, ‚sad, that these plants do not get better care, the more so am I thnak- ful to you for the dried flowers,which I will analyze as soon as I find time. I do owm Lemoine,Cact. nov gen & spec, but not Mono.Cat. Is this just a gatalog or does it have descriptions ?'nor the works of L. with illustrations. MISSOURI - BOTANICAL copyright reserved GARDEN E.aranthoides looks to me much like E.Wislizeni; if,however, no spe- cimen exists and no spine-bundles have been preserved, the name must probably be eliminated,as no authority exists. Ech.Wislizeri is also ball-shaned in early stagres. I zo throuseh your letter in detail and answer sequentially.- Op. cylindrica and vestita have the same seed formation,and if the one has short and the other long ceylindrical sec- tions,can not be separated any more than Echinocereus tuberosus and or can be dirided, but the name ovatus may be not fitting, but I stuck to the old name. I do not know vet, if these Bolivian aoracanthae etc. etc. belone here. I would be very much obliered to you for flower and fruit of Op. dlayarioides . It was certainly a great mistake of Selm to put C. Limensis to Echinocereus. When flowers will . haye to be knomm one will probablyiput it to Eplychni@z (=Cer.lanatus Humb) I myself know few Cereus flowers (except Echinocereus) ,and am therefore not able to classify them; only, I must put Phyllocactus, Bchinopsis,Pfeifferi with Cereus .I did examfiije Rhipsalis carefully and know the anatomical structure, which is described everywhere wrone- ly. The Paris svecimen of Op. myriacantha and Galdaname is mislea - ding. It is a Platopuntia like the other,prohably disfirured throush shrinkare,. Mam. Apassizii is also unfortunately represenrted by a weak spe- cimen,which can be expected to die too; thus I can not send it. The new Echinocereus from San Domingo has two fruit,which,howerver, are not yet ripe. I do not send seed of Agave virsinrica to you (thoueh I may, I want to look if fresher ones are on hand),but a small plant, which is really better, I send you seed of Cereus phoenie&uss(Sangere de Christo Gap) in southern Colorado. I collected miself seeds of Phoeniceus and zonaran- thus in 1874 at the upper Arkansas River in Colorado, but, unfortunate- ly, can not find them just now. I enclose seeds ofCer.Emoryi from 6. MISSOURI , BOTANICAL copyright reserved GARDEN Pr 1 en £r 1876 ard also seeds of two species of Echinocactus,which I obtai- ned in a peculiar way,and don't know,from where. During my 2 months absence last year,there arrived a broken glass with specimens in al- cohol and without labels and without letter ( this may have heen lost durine the turmoil in my house); in it a larre fruit of an Opuntia and 2 species of Echinocactus fruit. I enclose seeds of both; obviously, they lost the ability to germinate.

Hereby al- ways observe and measure: Ovarium, length and thickness (leneth to basis of the stigma) lengbh of the space in the basis of the tube, which is free of stamens,and forms the nectariums leneth of the tube as far as 1t is occupied by stamens. - Length of the space from the mass of stamens to the corona of the stamens,where this is present (Echinopsis - Phyllocactus,some, etc). Lenreth of petals, width,nun- ber, appearance.-. I say nothing about the exterior form,thoucsh the perlanth leaves or scales,or areoles of the ovarium must be taken in- to consideration,ete. Lensth of the entire pitti?F and its branches (stigmata) I must not forget.- Many of these measurenments are con- pllcated,and only, if one can examine various specimens,can one achieve definitive results. With Agavae it is similar - leneth of the tube below the seam (uppermost rim); lensth of fully developed stamens and the anthers,length of the full-srom ptätil. More about this later. 3 The 4 central spines of Echinocactus ‚of which you speak, re- present a pecullar problem; one can best convince oneself abont their nature and position by bönbanfıır an older spine-bundle at the base of an old plant with younger ones, farther up...

Yes, E. calif. & E.Emoryi look very much alike and the color of the flower should not make any difference. Seitz did a lot of prevaricating when I was in Prashfhut had fine items. e.e.

I would like very much seeds of Op.Salmiana; it often has fruit but I never found seeds in them. Is it really a cylin- drical Opuntia ? The Edötorrof the flower is abnormal. We don't have it here. May-be I will give you sometimes a list of itens, which I would like to have. And now to the Agavae. I already snyoke about description of the flower above... When only dried specimens are available, one is bound to make mistakes frquently, as the parts shrink and cannot be entirely softened; therefore I now declare always,if the description of the flower was taken from fresh or dried spechmens. Arave Shawii will give me the oportunity,to give a plate flower illustration in your dissertation, these are Aeryophilae and flower description will be of importance. - From"specimens shipped by you of Verschaffeltii I give the following description after drawing them,which you may compare this year with fresh flowers ı Ovarium (always of different length) 26,neck 5 mm= 31 mm.Tube to base of the pistil to the insertion of the stamens :10%3,from there to the rim 53, together 16 mm, lobes 17-18 mm; flower without ovar. 34 mm, stamens 6 mm loneer than cronm-lobes,pistil 15 mm lonser than erom- lobes, anther 21 mm long. 6.7 8 ) 10 MIıSSOURI ‚ BOTANICAL copyright reserved GARDEN The buds,sent to me,with incomplete flower in the center,are entirely unknom to me. You are not tellinse, where this bud comesifrom,if from an inflorescense or from the axtil of a branch or bract.- I did turn your attention to the study of bud-formation (bulbilli) and asked,to obserVve the position. By the way, we have the same with many Allium bulblets species,which have only blossoms,blossoms and iu ‚or only bulb- Dets; with some, all three combinations occur in one species ! It may be this way with Aravae.. The description and illustration of Arave Verschaffeltii was importart to me; I did not know it; it is the same with my still “ 9 imperfectly knomrA.Newberryi. Thus I would classify the Panriculatae into racimiformes and thyrsoideae. A.Shawii belonses without further ado to the latter, it does not make any difference, that the flowers are standing denser than with Americana or even more with deserti Baker in Garden Chrofäcle, I see,supplanted recently my clas- sification names with the old ones Manfrede,Littaea and Euarave; which he needs as suberoups of Agave.- Chacun secon son gout „- (French: Everybody to his om taste, E.D.) May Shawii and Ghiesbrechtii belonez together ? The description of Jacobi does not fit, but he may have had a very young nlant; the name squalideus fits better. However, it is an unpardonable error of mine, to have created the species falcata; striata,as described by Jacobi, is entirely my plant; and the description of the flower, which Jacob# doubts (?),confirms this even more.- Hystrix and others belone there too, as I suspect. a unde I know Bonapartea ee quite well’ with fruit,but never saw it flower.

BOTANICAL copyright reserved Bros vw. ee ne MIıSSOURI : BOTANICAL copyright reserved GARDEN St. Louis, Mo July 28,1877 Dear Dr. Weber I have two letters from you, which need answerine,but have not been able to set to it. But, noı comes the London Gardener's Chronicle, a garden magazine, in which Baker began several months ago a revue of Aravae. There I find pe 40, issue of July 14 Arave scolymus mertio - ned, and, to my surprise, A.Verschaffeltii is quoted as symonym. Sander's Refurium botaricum V.2 t.328,which I possess, is riven as re- ference. Now, I have a photograph by G.Thurct of Antibes of scolymus - unfortunately’only the uprising but not yet flowering branches; But, I do have dried flower and fruit of the sane plant from Antibes. From this seems to emerge,that much confusion is abroad. The scolymus Hort. Thurct is different from the one illustrated by Sauder,and arain dif- ferent from your Verschaffeltii. However the illustration of Saunders approaches the inflorescense of your Versch.Hoiw the one of Thuct was, I unfortunately do not know.- Such, all kinds of interesting questions arise,.- Can't you dry an entire branch of Verschaffeltii and other Ara- vae for me,and if too thick,to split them lenrthiwise.as the late Thurct sert them to me ? and then single flowers splil open. I now go throush your letter. First however, that Baker re - sards A.Poselgei (Lechuquilla) and A. heterocantha as different species. Ihat may be true,but the flowers received from Munich of the latter are completely alike those of the first. I have prospects to get the Lechuquilla from Rio Grande: I see a small specimen here in a garden: more are promised.- I am sorry, that I can't send you Opuntia Davisii ” from West-Texas;it erows quite nicely for me but never bloons, same as frutescens. I wrote for the latter to San Antonio (if nisht-florwering, as you believe - or rather a permanent flower) ,but did not receive an answer,» I am glad, that the plants arrived so well - as the cost was reaso- two made roots and grew.- Thus, it js a much-fruiting Cylindropuntia from Arizona,and that is all I know of it.- If the good people would only give the home country of their importations,it world help a lot es later, but how often does that not oecur. Have you grow Bigelonii ? With best culture, grafting,etc. it may be developing best. Of course, it should be named Cereus longisetus I It comes from the same territory where Agave maculata srows,from the upper Rio Grande,and the area near Eagle Pass = Santa Rosa. Of the latter leaves have been sent to me recently. We had it here in culture and flower,but lost them. Do you have it ? It is strange due to the short anhthers. 6.7 8 MIıSSOURI . BOTANICAL copyright reserved GARDEN - £ - Certainly, Agave vireinica will stand your climate and will do PL I Ze better in the onen than in a not. It erows wild here and we have ten- paratures to - 18 or 20 R. But also terrible heat, and that is re - cessarvy for the wellbeinge of this native plant.. I see that Baker mentions the A. Consideranti (?) as A.Victoriae. £ More in Garden Chronicle "it doubtless shonld be regarded a foreien and aistinct group " It is possible that my angustissina and geminiflora fall toge - ther. Unfortunately, I have nothing but leaves. A. maculata Regel is likely = variegata according to Jacobi's description. What has been mentioned by H.Salen as my plant,can hardly be determined now, but Salen did receive roots of my maculata (macu- | Q lata Hauk).- You speak of sceleWbut these Agavae do not die off, equally not maculosa = vireirica - but produce side-sprouts from the cormus. My vireiriana in the zarden blooms every year from the same Your description and specimens leave no doubt, that (if your plant is the zenuine from Resel)you have in front of you that,which I consider to be variegata.And, once again, maculosa Hauk differs from all Agavae knowm to me throush the short stamens (?) as HE. pic- tures them and I describe them. What you report about the sweet exudation, is of interest to me; I had seen it in overabundance with Shawii; thus, it seems to be universal. Strange, that nobody has said anything about it. I do not have any live Cer,.gonacanthus,thoush I collected them myself in southern Colorado - same with Ech.Simsoni - But as now every year a lot of travellers for pleasure go into the territory,. it should not be difficult to obtain live plants. It is tough to cul- tivate Simpsoni as it demands alpine air. 8.000- 9.000 foot high I Your G. Engelmann August 2,1877 (translated from German script by Edear Denison, Feb.1988) MISSOURI .

I wait with answering un- til the package arrives; for now only, that Pfarrdorffer's *" flat" Opuntia from St. Francisco is my old friend Op. basilaris. It seens a ne daifficult to raise and has perished several times for me,and now I have again quite young sprouts of which the middle menber has rot- ted -it comes ffom a very dry area.- Did these and the next ones not germinated ? The other "* thin-stem " (better named cylindrical) is, as you assume correctly, O.prolifera.. Observe exactly, which Agavae die off after flowering,and which keep on erowing and bud from subterranean parts, like Yucca filamen- tosa. A.virginica and macnlata certainly do sosand keep erowing. Shawii has died after blooming,but carries a number of buds. And the seed-forming ones: will probably keep growine from side-buds as with oO | Yucca ®loifolia „, I received since then the package with flowers of: Agave, but, because I am deeply stuck in the oaks,and must use all ny free time on them,I have not yet begun any examinations.- Of course, dry, shed flowers are better than none, but even after they have been care - fully made soft again, and then are compared with fresh ones,you will find, that they will never take on the former shape; Of course, the insertion of the filaments remains the same,but the proportions have been changed, the parts remain shrivelled;therefor it can only be of value to 1) to sketch the fresh flower,reraräless how simple 2) take measurements of it 3)to dry fresh flowers,that have been split and to dry them under rather strong pressure,so that the parts cannot shrivel too much.

April 4, 1880 Dear Dr. Weber Your last letter I received’ at the beginning of 1878 and answered during the Summer of 1879. I was then in a sad’ mental and health state, but I do not know, if my letter came into your hands, as I hear now from Strassburg that you are not any more in Lvons, These lines are supposed to be a query, a probe of your life and doing,and, specially about your interest in our favorite plants and your studies of them. My om efforts have made little progress since the long interruption in our correspondence, but I carry still materals and observations together. Thus, I received now fruits of the Yucca (Palma),which is so abundand near San Luis, which I offer you elad- ly as well as an Agave from there. Here, with us, an Agave Parryi flowered of which I had made a photoeraph. And now I receive young plants of the Agave Victoriae Resinae from Monterey, to which you directed my attention first.

Soon after receipt of it, the severe heat in St. Louis chased me away,the more so as I had suffered 2 months from a had, zout-like rheumstic fever, from which I could not recover well. I received your letter shortly before my departure and I looked at the collection of seeds in it only casually; The letter itself I took along, the seeds lie at home. Why did you not write last vear; I could have sent you a mass of material from California and Arizona, believed however,tharks to your silence,that you had given up on EGacti and Agavae. By the way,. I brousht with me many (or at least) several Cylindropuntias,which er) ws ®) x Pin cr Bun 7 3 are growing and of which I can send to you netime,thoush these plants ship worse than all the other types of cacti; most of them dry up; should one send entire,old plants rather than single branches ? I myse 1f did collect mostly \zuxck and broueht them home, young plants or sections which had fallen to the eround and took root. Also, I have again the poorly Yalyed but beautiful Opuntia basilaris. Does it exist in 0,9 The large Opuntia from Galapragos (0O.Galoparii ?) and myriacantha live with us and erow well. Yes, I had a lovely trip,but it was unfortunately too short,into the cactus territory of southern Califorria and Arizona; in the latter country I found a Yucca, similar to baccata ‚wrnich I consider a new one and described as en ee £ sent seeds to various institu- tions in Europe and, also, to Prof.Decaisne in the Jardin des Plants, also Yucca elata,formerly named by me Y. aneustifolia var. elata, a mafnificent plant with an 58 foot high stem and a flowerine shaft of 8 - 10 foot hirsht - well differentiated from Y.anzcustifolia;also seeds of Agave Palmeri.

In any case, some show that there are forms which I did not know until now, and that one may not cre- ate systems based on limited resources of observation. I must have told you before, that a half -ripe fruit of Peirescia - subulata i received from Palermo, is definitively an Opuntia. I believe, that others have already called it Opuntia subulata,based on a few cer - tain symptons,. Of Cereus setispinus I have only that one specimen.. I had hoped, that you could propagate yours, I send you at the same time a small package with some small spe- cimens of Echinocactus Simpsoni,which here around me,and in part with- % in the small towns is common. You find also seeds of it in the pack- age. It erows on gerarite rubble and eravel in old moraines with very rich, black,“fertile soil between the gravel, and will demand so-cal- led heath-earth between eranite-sravel. I also found one, which was flowering by accident,the fruit had fallen off. The flowers. of those \ that bear fruit are 3 - 4 " in diameter.

I am delishted, that the Echinocactus Simsoni seems to begin grwoth;it sgrows very poorly in cultivation; may it demand more moisture. Where it grows, it is co - vered the entire winter with snow, but there is very little rain in Summer,but frequent, With me, it has alırays perished. Today you receive seeds for a new,interesting Echinocactus which I name xeranthemoides; The calyx leaves ei shinyylike a Xerenthemum or Helychrysum, but ui, yellowish. I have only one fruit and one spine-bundle. It is closely related to my E. polycephalus and most likely just as difficult to cultivate; it comes from the boundary of Utah and Arizona. Further I enclose seeds of Cereus triglochidiatus,which I Y collected myself in New Mexico. I prefer the name,which was given later but is better, C.gonacanthus, as the number of spines with edges is mostly more than three. It is a fine, strong plantwho'se De bushes I found below conifers at an altitude of 7,000 - 8,000 feet. The? you receive 2 Platupuntiae,the one from Arizona may be my O.angsustata.

Aus. 5, 1882 Dear Dr. Weber I should have answered your letter of June 10 long ago, but it was pushed off, sqeezed out by the daily business, First, it was a mistake,that I positioned that Cereus in Saltillo,it came from San Luis,where it is being cultivated as: Parry writes - not wild, but commonly growine in the mountains.. The fruit sets on the market as Petaya, mine came dried, but was quite tasby. To correct my error and to clear up the matter as much as possible, I send to you the sketches of Parry with the request to re- turn them. If we could obtain all those cactiwith dried specimens and descriptions and drawings of the fresh specimens, we could soon re - cognize the species correctly. But there remains always the difficul- ty to determine under what names they appear with possibly pityful specimens in cultivation and books by Pfeiffer,Salen or others, Yes, I know well, that you wrote about Agave Verschaffeltii, but I considered the inflorescense much more as a panicle contracta rather than a srica expansa; but. in the end it comes out to the : the question is, if Verschaffeltii_ does always have such multi-flowered short branches of the ear ("ear",like an ear of wheat,E.D.). With my A. heterocantha from West-Texas ( of which I received one of these days a fine,live specimen. We are now 2 or 3 days by railroad from these areas and the South with several lines, of which at lest one reaches across the Rio Grande) - - thus, A. heterocantha is mostly regularly geminiflora ("gemini" Latin = a a. ioyera #0) And the oririnal in Munich flowered the same way ( I saw dried spe- cimens in the Munich herbarium) but once in a while a twiglet seens to produce % or more flowers,and with this one specimen, were small branches,broad, pressed flat,like with a true pani:o»l'tis,which had h > ”. u ———— up to 10 blossoms. I can send you one, if you want. At the same time 9 10 MISSOURI . BOTANICAL copyright reserved GARDEN - 2 je I received from the same industrious collector recently several young Arave Wislizeni, which he found frequently in West Texas. Of these ‚you shall have one.- Do you also want younz ones of sisalana and iegeida and a medium formy which were sent to me recently from South 3 Florida. This correspondent in West Texas is a military doctor,who is stationed there at various boundary posts and frequently travels throuseh the wilderness with expeditions.- A. Dr. Havard, a born Frenchman, if I am not mistaken. In the Fall I will send you these items, as well as Op.missou- riensis. Do you have from me Op. Davisii, which I atrers, auch a lone time,and which nobody has ever provided for me in flower or fruit I! I can also send you my Op. rufida (closely related to microdasys) Op. basilaris, O0. fragilis, 0.Utahensis,0.rutila ( probably a red- flowering form of Missouriensis). How ? The postal service accepts larger packages as Packet-express,which also is not exvensive, That is supposed to begin later,but in October, With the things, which Parry sent then were also the two (only ?) specimens of Echinocerei, which grow in the interior of Texas. As the flowers- had never been described and the plants poor,I had difficulty je to determine them. But, I believe to be certain now, that the one is Cereus einersscens DC,the other C, acifer. The first is much eaten (i.e. the fruit) under the name Alilcöche, in San Luis, and has violet [7 u] or rose-colored flowers,which are open only during the day; the other has red flowers, always open and no edible fruits.

In the meantime, it will happen with this letter as with your last one,which followed me from place to place until it reached me finally; but I returned home too late, to be able to send you the desired items;that, thus, must be post} poned until next Spring. But, I will enclose a few thinegeszalso seeds of Agave virginica, which I received as well as a plant a week ago; they grow 10 -— 15 miles from Now I want to tffeat particulars of your letter. Thank you for returning the sketches and your remarks about them, . That the seeds germinated, is very nice,I hardly expected it. I cannot get now to the treatment of the cacti,and, thus,the plant, which I received from Parry, of which I have complete material,may have to be laid ad acta.. Thank you for the large seed of Cer.serpentinus ; if I had more ’ of it, I would analyze it; but as is,l do not want to destroy it. it flowers here often enough but has never set fruit.In contrast, I found on a Cer. triangularis here a number of good tastine large fruit. I assume, you know the seed of this. Ihear now, that a commercial gardener in San Francisco,F.A.Miller has sent seeds and plants of cacti to Europe,also other plants (dried) tubers, bulbs and seeds,. Merchantshave started business in California, so that the products of this area may become auite available.For Mil- ler I identified a lot of Cacti,Cypresses and such. wid, Opuntia seeds I have the same experience as you,they gerni- nate sometimes very late.I do not deal any more with their cultiva - tion,as I have neither time nor good oportunity for it;but if I can distribute the seeds, I do this with pleasure. 6 . ' MISSOURI . BOTANICAL copyright reserved GARDEN y on 2 en 1 I already wrote to you about the two Echinocerei from San Luis,which are common elsewhere,acifer andceinemäiscens, which I knoir well in many forms(with spines, which are quite variable);the scarflet- red acifer is quite different from the violet or rose-red cinergdscens,of which : x I sent you seeds. A number of cultivated forms may belong here;possi- bly also my stmamineus Yes, I had not thouseht of pectinatus and subi iS, eaually .not of Bolandieri and prostrata;s- pentalophus, Ehrenbereii1,Blankii and others I do not know and they may be vperhaps ke synonyms of the above; that they all vary much in spine formation,you know as well as onzisetus I gave to a garden,and there it does worSe thanfrith ne. Since 20 years it has only a weak sprout emerging from the base,while that of the previous year has died off;.thus it vegetates,but I cannot send anything. You did not seem to fare bed&ter or rather worse. I could put you into shock about Mam.micromeris, by ‘telline you, that I find analogies even with Melocactus; e.g. the flowers thensel-., ves:and the ephemeral, club-shaped spines: of the flowering part of the plant. I did study Melocactus well’ ,thoush my material is not rich.. The sad part 18, that, if one gets to see a Melocactus in flower,one does not zet the chance to dissect it,. However, I do have dried mate»- rial,which does show me the transitionm’from the spine-bearing to the flower-carrying part of the plant,and proves that spine formation ceases entieely at the inflorescence, not beine modified.,. I am glad, that you have Opuntia Yutila; I had it several years in the open and in a cold winter it perished; I had raised it from seed. I, now, have a correspondent in San Bernadino,who, though a farmer, is interested in botany and also cacti; he has cultivated a number of the cacti there, and I shall send to him,what is not doing well for mes»- but not just now the unhappy longisetus.

However, I could not have handle 16%; because I have been sufferine the entire Winter,and can accom- plish only little. I intefd, if my strength permits, to travel next month'to Burope,and, and, if possible, to restore my health throueh this ocean voyages;s itis however very doubtful, if I can see vou in the distant Rouens but I may be able to hear more of- ten from you. I can imagine, that you are much occupied,but you could have mailed me a postalcard in reply to my letter of November,and in - form me about your residence,shipment of cacti, etc. Then I would have knowm ‚where I stood. That my Cereus (Cact. of the Boundary) is not variabilis , I knew a lonz time and corrected the mistake; it-is without doubt bg princeps according to Pfeiffer. But if it. is pentagonus_ Linsei, ar is very doubtful for me. At least, I observed a Cereus in flower last year,which I considered to be pentasonus,which, however, is very different from my princeps. Here enter again the old, poor descriptions and, therefor, the difficulty to identify the old species. This Cereus has ( as princeps and variabilis ) flores albi erandes nocturni,but the ovary is not covered with scales; my princeps has only spine-bundles on the ovary and variabilis has very few scales. Further, pentarzonus as well as variabilis have a corona separated from the other mass of stamens, whereas princeps has stamina continua. I do not know the seeds of penta- gona, those of the other two differ much from each other.

Dec. 24, 1883 Dear Doktor Weber I just receive your interesting letter. Now I ask you for 3.07 sll the world,how could Janybody recognize Labouret's and Pfeiffer'!'s Cereus pruinosus ( not certain of species, E.D.) in the Plants by Parry ! That is a real new proof,that it is impossible to study cac- ti,if one does not start at the beginning... Here we have a plant known for 50 years in eardens,20 years aco you saw it in Mexico ard did not recorrize it; 5 years ago Parry collects it with flowers = fruits,and these too were not recoenized, until the seeds rerminate and produce young plants. On these little plants we must now rely ! Can we do that before they are 10 - 20 years older ?By the way ‚I find a confirmation of your statement in a note to Parry,that he 4 had seen only a cultivated specimen in St. Louis (the one dran). * The fruit is supposed to be known everyplace as Pitakaya and in markets;the spines are easily wived off,the flesh is tasteless but refreshing. At times the fruit have a diameter of 2 inches. The description says, that the furrows disappear later and be- come quite flat. Parry's crossection did not show this at all(this is the one I sketched). Later more. Today I have time only for these remarks. Can you read my hasty writing ? Can you determine,ıwhat the man's name is,for whom Pereskia is named: Peyesc, Peiresc or Peeresc or sk „- My correspondents in southern France cannot help me. Some- place it saysı Peyresc,rich repociant de Toulon (rich inhahitant of Toulon), other places Nicolas Fabricius Peiresc of Aix,member of Parliement. I would like to determine the orthography. I think we should get our minds together about my planned work on Cactus. Naturally, it deals primarly with the cacti of the North American Flora,but I would like to include as many others, as I 6 .7°° MISSOURI . BOTANICAL copyright reserved GARDEN e 2 AR have learned to know exactly,of which I know the flowers and fruit. Further I care to exact\y determine the synonyns. What concerns the exotics (i.e. cacti outside of our Flora) I must depend on you, as I hardiy know the cultivated cacti. You give me an exenple in your let- ter in the synonym of Cer.eriopterus: emd ’eriophorus it can not be named, because the older name Cer. repandus Lin.,‚Cer.repandus Haw. has been accepted and determined,that this is really the same plant. Thus, it becomes in the future Cer. repandus(Lin) Haw. We, further, must recogrize,what is now generally accepted in botany, that no name is valid, unless accomparied by a EEE des- cription,wnich has been published. Of the cacti are many, which exist in gardens only, on labels; these would have to be ienored. You your- self give me an exemple Cereus monacanthus Lemaire ,„ a name, which I cannot find anyplace, one of the oldest,but neither Lebouret nor anybody eine: else sccepts it. Has it not been published with a description "If so, * then it certainly must be accep begänn the name Nartini.put aside; otherwise however Martiri remains,thoush it was published in an ob - scure,not strictly botanical journal. With much cultivated eletis with such names, one could make an exception,. % Desigenations like Hort. Be ri in,Hort.Paris,Hort Angl. would have to be eliminated,bacause they are not publications; Otto Pfeiffer,Salen woulg have to stand instead. Do you want to publicise your new cacti in my work,thst would be quite nice,but I would want to &nclude them only if their material is complete.- otherwise the confusion could be possibly multiplied.; e.g. E} by accepting"Cereus edulissimus" this would happen on your om state- ment,.
