This is a fragment of a letter to Dr. CT. Engelmamr, 



OCi jfvcftt'pages 1 and 2 are missing. E.D.. 



could perhaps be of use, as, quite generally, I perrait my- 



se[f the request,to make use of my possible Services concerning the 



giving of inf orm#/tiom. 



And now I take permission to pronouce a few wisheff on my part.. 



ij You wrote to me earlier, that you had seen Call i tri che Austin! f rom 



Bahia. Could you not provide me with a f ragment for viewing after you 



have come home ??I am supposed to work on the group for the Flora Bra- 



silefesis, and though I do not doubt the diagnosis in the least, I should 



have for this purpose the autograph . I have not found the plant in? 



question in any collectiornl^ot even in that of Märtinus.In connec1;iorr 



with researches instigated in Brasil 1 for the purpose, I reeeived recent- 



ly from Rio de Janeiro the Lemnajpaucicostata .If you should get in the 



future, to again examine the latter,, direct your attention: to the 



wings on the vortex of the roots, normally on the sprouts of young,, 



half -grown plant s. These Taings are one of the MKxt strängest*" charac- 



teristics for the Speeles on which they occur ( perpusilla . pauclCosta - 



ta, ,and angolensis ) and, in addition, a superb characteristic for the 



group formed by these as against the minor on one side and the forms 



with a one-nerved sprout on the other.. 



In connection with the examination v of some of your speeimens in: 



alcohol from you of L. minor from St. Louis, I 1 , finally, found one 



with flowers; I' 7 took out the Ovulum, thus eliminating any possible 



doubt about the correetness of a north-american minor and that be- 



lonprinlT to the Old World.. 



2) Could it not be possible, to obtairr a speeimen of the beauti- 



ful Lemnaceae of Wright from Cuba, as I saw them in your collection ? 



some time back
