NOTES ON EUBI. 207 



this term applied by several German writers to the female organ of 

 Chara, and contests the view of A. Braun and Sachs that the 

 carpogonium must be regarded as a metamorphosed shoot. The 

 " enclosed (behitUte) oogonium," as he prefers to term it, Celakovsky 

 considers, on the contrary, to be a metamorphosed foliar structure 

 or portion of a leaf, homologous to the ovule of Phanerogams.

17. RuBUS GLANDULOsus, Bell. — By the kindness of Mr. Bagnall 

 I possess specimens of a iDlant gathered by him on Bromsgrove 

 Lickey, and supposed to belong to R. Koehleri var. infestus, which 

 now seems to me to be a form of the aggregate R. glandulosus, 

 api^roaching closely to R. rotundifolius, Blox., and also to 

 R. dejie.videns, Boulay, but differing in some respects fi'om them. 

 The shape of the terminal leaflet is different : it is much broader 

 in its lower half, and much more cordate at the base. Two of these 

 specimens have the dentition described by Boulay : " Les dents 

 grandes et fortement refractees qui terminent les principales 

 nervures des f. caulinaires." On Mr. Bagnall's plant they seem 

 to be as remarkable as on Boulay's specimen (No. 125). The 

 stems of all the three have similar prickles and aciculi ; but there 

 are much fewer (indeed scarcely any) hairs on Mr. Bagnall's plant. 

 My opinion now is that these three plants are forms of the segregate 

 species, and that it must bear Mr. Bloxam's name, given to it and 

 published nineteen years, sooner than that of Boulay, namely, 

 R. rotundifolius. 



Mr. Bagnall's plant differs fi-om my short description of 

 R. rotundifolius (' Rubi,' 252) by its terminal leaflets being not 

 only duplicato-dentata, but duplicato-reflexi-dentata, in the manner 

 described by Boulay. On none of my specimens of R. rotundifolius 

 from Twycross, nor on the one from Cowley Park, are the leaves 

 more than duplicato-patenti-dentata, for the teeth which terminate 

 the chief veins are simj)ly more prominent than the others, although 

 showing a manifest tendency, but only a tendency, to be reflexed. 

 On the plant fi-om Bromsgrove Lickey the recurved hooks, formed 

 by some of the ^Drimary teeth, are as remarkable as on the 

 R. deftexidens of Boulay. It appears, therefore, that Mr. Bagnall's 

 plant has differently shaped leaves, from either of the others, and 

 also a less hauy stem ; that it agrees exactly with one of them in 

 its dentition, and with both in most other respects. 



18. R. GLANDULOSUS ft. HiRTus. — Thcro are two plants in Mr. 

 Bloxam's "Set" which seem to belong to the same species: — 

 (1) That named R. fuscus (from Beaumaris) is apparently the 

 former R. fuscus of Lees, Bloxam, and myself. I have been long 

 convinced that it is not the R. fuscus, W. & N., but the R. hirtus,
