62 THE JOURNAL OF BOTANY 
ment may be altered or modified as the me iesee of the anatomy 
of the other species is studied. The author considers that the 
‘leaf endowed with sheath (and outs is more primary than the 
sheathless.’’ In this I entirely agree, as, I believe, does Mr. Fryer ; 
become so at an early stage. 
As the result of his study of Potamogeton fluitans, Herr Raun- 
kiewr shows that the plant generally pee as hybrid P. lucens x 
natans has sub-epidermal bast-bundles e bark and vascular 
bundles in the walls of the lacune, cn se ‘‘Neckar”’ plant has 
not; the hybrid also differs from that in having the axial cylinder 
smaller and differently arranged. The difference in the two figures 
of the sections is certainly very noticeable. He goes on to discuss 
which of these should bear Roth’s name, and arrives at the con- 
ikon that it should be the Neckar plant. Unfortunately, he does 
not seem to have noticed the remark I made (Journ. Bot. 1901, 198) 
respecting Schreber’s specimens at Munich, which, from the obser- 
ie of Roth, seems to me to make it certain that these specimens 
aaa in the U or States as Lonchites.’’ I was, of course, 
saying that an een botanist would ees — it Lonchites ; 
not that it was Lonchites, for I knew that was not s 
must utter a uta against calling the Noskar plant ‘‘ fluitans 
of Roth,’’ unless the two are combined, as they are by Ascherson 
and Graebner (Syn. Mitteleurop. Fl. i. pp. 8308-9 (1897) )—a view 
which the author shows to be untenable. If the Neckar plant is 
not the same as ap American P. Lonchites Tuck, it must have 
another name. almost every author in Europe Roth’s fluitans 
is looked upon as a cashes, and to call the Neckar plant ‘ fluitans 
of Roth” seems most undesirable. Aaenih Bidaikrs:
