mentioned,made me doubt^he natural certitude of the two part 



grouping in favor of your 3 part. Fthought to have seen earlier 



bracteoles on the brasilian C.def lexa; Wlth renewed examinations, spe- 



cifically for this point,I found none, und would rather think f that 



my memory fooled me. I do not put much weight on this point,and I 



am used to miss the bracteoles for pedunculata and hamulata , and that 



with one speoimen completely and with the other in part.. If ,however„ 



there would be never bracteoles^ on terrestrial forras,then this would 



have to be treated seriously. . Nbw, the New Holland Callitriche are 



interesting in a stränge way. C.Miflleri ( macropterix ) has crystals. . 



net-like thickening (the most beautiful of all Callitriche) jis gene- 



rally an exquisie terrestrjqi species,and does not have bracteoles*. 



The 2 Strpvv7<p^<^ species have also nice net-form thickenings, the one 



on top of it has crystals, they appear already through the fruit as 



next relatives of C. peploides ,and , quite generaüy, they appear through 



the most important characteristics as exquisite species of terrestrial! 



species. But the one C UW)&^v\od<x is not only found in a terrestrial 1 



iyv water 



but also in an easily recognizable swimming fornr 1 (rosettes etc),and 

 further, both land and water forms have bracteoles tl hope to get irr the 

 future possession of audtralian Callitriche and i*ould share some withr 

 you*up to now, I know such items only fron foreign herbaria. How carr 

 one under these circurastances becorae aquainted with the correct species 

 of the Ar&phiblae t ?' Calci te crystals occur,as far as r know, , only by 

 some of the first^but not with all i t as I mentioned already.. The rein- - 

 f orceraent lasts (verbatim: the thickening lasts, E.D..) form the inrr jr 

 parenchyma layer, which become net-like for the terrestrial forms-, how- 

 ever there is an entlre transitional series from the tender ,ray-like 

 lasts of our europaean species^ ,which accomplish more tender and stron- 

 ger.slanting appear ing' nets by slanting constructiorr ( free and possi-
