 In conclusion, a few words may be added regarding the 



terminations of some of the trivial names. In consulting the 

 literature of these water-crowfoots, one has been struck by the 

 great want of uniformity in two matters. One sees indifferently 

 B. hololeucus and B. hololencos, B. tripliyllus and B. triphyllos. 

 On the whole, one prefers the Latinised form in all such cases. 

 Again, there is much inconsistency in the use of one "i " or two 

 " i's " as genitive terminations. One sees indifferently B. baudoti 

 and R. baudotii, B. godroni and B. godronii, B. hachi and B. bachii, 

 B. lenormandi and B. lenormandii. The former would seem to 

 be the more correct form ; but the recommendations of the 

 botanical congresses tend to keep the matter in an unsettled 

 state, for they illegitimately ask for two " i's " when a word 

 ends in a consonant, and are inconsistently content with one " i " 

 if the word ends in " -er." It seems, indeed, as if the recom- 

 mendations with regard to the construction of botanical names 

 need revision by a committee of scholars. 



MISCELLANEA BEYOLOGICA.— III. 



By H. N. Dixon, M.A., F.L.S. 



(Continued from Journ. Bot. 1913, p. 330.) 



Sematophyllum acutirameum (Mitt.), a "composite" species. 



In the course of working out a collection of mosses made by 

 Eev. C. H. Binstead in Ceylon, it became necessary to study the 

 above plant. It was described by Mitten (Muse. Ind. Or. p. 106) 

 as Stereodon aciitirameus ; the localities given being " In Ceylon, 

 Gardner \ In mont. Khasian., ad Moflong, in pinetis, Griffith ! " 



* Probably this ought to be cited as a subspecies ; but the point is con- 

 fused by Fries placing his " Batrachium " heterophylluvi under ''Ranunculus " 

 aquatilis.
