which may surely be regarded as closely related to each other, 

 thus forming an apparently natural section or group. The same 

 view was, also, held by Tuckermann, who placed them as his 

 Phyllostachyce next his Careyance, in which we find G plan- 

 taginea, C. gynomane and G. depauperata. It was Professor 

 L. H. Bailey that first enlarged the section Phyllostachys, and 

 this author includes not only the three species enumerated 

 above, G. Willdenowii, etc., as a subsection " Bracteatce" 

 (Bractoidece Bailey), but also G. Geyeri Boott and G. multi- 

 caidisBa.\\. as representing another subsection " Phyllostachyaz" 

 however with no very clear distinction. As a matter of fact, 

 the section Phyllostachys became confused by this enlarge- 

 ment, which is readily noticeable from the statement by 

 Professor Bailey that the section is not only u to be regarded, 

 probably, as an offshoot of the Montana, but also to be con- 

 nected with the LaxifiorcB by C. multicaulis, being related to 

 G HitchcockianaP It is true that Drejer considered his 

 Garices dactylostachyce as derived from his G. sphmridiojphorce, 

 but this author would not have included the true Phyllostachys 

 in any of these, judging from the diagnosis, while he might 

 have included G. Geyeri among the Dactylostachyce. In a 

 lately published paper on the Garices of South America, a 

 German author, Rev. G. Kukenthal, follows Prof. Bailey's dis- 

 position of Phyllostachys, and includes another species, G 

 Sellowiana Schl., which, however, shows no marked affinity to 

 either G. Willdenowii or to C. Geyeri. Rev. G. Kiikenthal, 

 moreover, considers Phyllostachys as a subsection of Drejer's 

 Sphceridiophorce, which does not seem to be in conformity 

 with the original diagnosis of this section. While thus 

 Torrey's Phyllostachys, even if reduced to a section, has been 

 maintained through so many years, Duval-Jouve's (Edipostyla 

 does not seem to have gained recognition at all. In the Cata- 

 logue of European species of Garex, Dr. H. Christ has only 

 enumerated G cedipostyla as one of the Digitatce Fries and 

 placed it between G. JTalleriana Asso and G. pihilifera L., 

 while this same author has counted C. depatiperata Good and 

 G. olhiensis Jord. among the Phyllostachyce of Torrey. If 

 we consider the Digitatce as understood by Dr. Christ, these 

 contain representatives that are so little related to each other, 

 that we must combine the Sphceridiophorce, the Dactylo 

 stachym and the Latnprochlcence with each other in order to 

 get them all together. It may be, however, that G cedipostyla 

 is in some respects related to, for instance, G. digitata L., as 

 suggested by Dr. Christ, but we cannot find any characters by 

 which we might connect this with G pilidifera or with G. 

 supina Wahlbg. Future research must decide the proper 

 place for G asdipostyla ; in the present paper we intend only
