Besides, Gray who is working on a revision of the Composites, should have your Solidagos and Asters,and likewise the Grindelia (which suppos- eäly was imported?),for investigation,.

The Michauxii I collected many years ago in Missouri,the other was missing in my herbarium, The Anacharis has male flowers,ours having 9 anthers, It is report- ed that some occurs with three(anthers),perhaps another species; I have not seen it.

First of all for the Isostes which I now can better study from the numerous speo- imens. It is my I,Butleri from the Indian Territory, which is very olosely related to the I.melanopoda but differs,beside other charact- ers,in the mach larger Nacrospores,larger,blackish,and very spinous Miorospores,and in the absence of a velamen. But the most interesting point is that I,Antleri is dloeclous;I have examined probably 100 spec- ies from the original habitat and determined this fast, Among yours I have found thus far only female ones;but the more abundant material permits me to determine also on your plant this character, Other Iso- etes are monoesilous,but melanopoda is 1/3 male,1/3 female,and 1/3 mon- oeclous, Therefore midway between Butleri and the other species, I would have liked to have had very much nore mature specimens; perhaps you will colleet some in later yearsjit seems that the plant occurs en different habitats. Collect abundandly of this interesting plant and try to get both sexes;thus it will happen that you indiseriminately will generally find equal quantities of males and females, The Cusautae are G,rostrata from the mountains and G.chlorocarpa from the Polygonum at Nashville, Your Polygalla Nuttallii is rather P.san- gulnea,a form with narrower wings and smaller oaruncula of the Seeds, Nuttallil is different;jit has much smaller flowers,ets. Your Plantago is heterophylla(from many pitteäd seeds in the sapsule),. I am enclosing P.pusilla,which has only 4 smooth seeds, I also enclose URN of Arabis Iyrata. Your plant is A,ludovico- iana. | Schoenolirion was very welcome to me;so was Asplenium Braäleyi,which MISSOURI: 5 BOTANICAL copyright reserved GARDEN I did not possess.

One of Michaux” rarities;jrelated to corollata, Your Chara is Nitella accuminata ,subsp.subglomerata A,Braun,it seems to me, Astragalus 6aryocarpus may be right,but one should have flowers, I “ did not know that it occurred East of the Mississippi. In Quercus bicolor I am interested. The flowers may point to this specles,but the sessile acorns and especially the scales of the cups, first of all the hairy anthers exclude any doubt that it is an abnormal form of Quercus stellata ‚or a hybrid. Have you not a summer specimen? with mature leaves and better fruits. I would like to see more of At; if a hybrid,stellata is one,but which is the other parent? Be sure and visit the tree again since it grows at Nashville,and study it and its visinity. I am glad to see Vitis rupestris agalnzit is a trans-mississippian plant too,which occurs east sporadicaly,and was found by you, Stenanthium angustifolium is an entirely different thing,of which I breakıoff a branchlet and enclose;I have found it this summer not far from the city. Your plant is perhaps Nolina Georgiana,which I do not knowsit has no fruit,by which it easily could be determined. I do not say anything about grasses and Carices,since I never have studied them,and which I want to study but sannot teach., It is time that I render you a service.

Much esteemed Friend | many thanks for things dispatched; examining them I have put down the notes above. In addition,the Crataegus specimen are left. But though the species are difficult enough if one has flowers with young and fruits with old leaves,it will be entirely impossible to determine specimens of leaves other than by guessing. Thanks for the pretty C.cordata,which we did not have here at all; the small fruits ape like the (searcely ever cormdate) leaveß very cha acteristic, In future do pay attention to the stipulae, which more or less „are found mostly on the young shoots. Your cordata which is just blooming seems to have already dropped them, They are often semi@ lunary or falcate,sometimes linsar;but I do not know yet of what diagnostio value they are. On Oxyacantha they are very well developed,on No.2 they are linear and small and are dropped soon. No.1 probably C,.arborescens,. No.2 is distinguished by the flabelliform nerves,that is to say the lowest nerves run far up and are much larger than the upper ones.
