208 THE JOURNAL OF BOTANY 



On reaching the last three groups in our list, including all, or 

 nearly all, the Eubi with very mixed armature, the difficulty of 

 comparison with the concluding pages of Buhi Europai is seriously 

 increased. This special difficulty arises partly from the greater 

 range of variation, which appears to be a genei'al feature of the 

 more glandular Eubi, and partly from the circumstance that these 

 highly glandular Eubi with very mixed armature are, as a rule, 

 much more thinly distributed than the members of the earlier 

 groups — in Britain at all events, and probably in most parts of 

 the Continent also. On these plants, therefore, I propose adding 

 only a few brief notes of a more general character. 



Thus, if we consider them in the order in which they stand 

 in our London Catalogue, ed. x., it may be said in general 

 terms : — 



1. The following species are now recognised as common to 

 Great Britain and the continent of Europe: — B. rosaceus Wh. & 

 N., B. hystrix Wh. & N., B. Koehleri Wh. & N., B. viriclis Kalt. 

 (sensu ampliss.), B. Bellarclii Wh. & N., B. hirtns Waldst. & Kit. 

 (sp. collect.), B. dumetorum Wh. & N. (sp. collect.), B. diversi- 

 folius Lindl. (a species in Bubi Eiiropcei, but a var. in London 

 Catalogue, ed. x.), B. corylifolius Sm., B. Balfourianus Blox., 

 B. ccEsius Linn. These all are strongly marked plants, and may 

 be regarded as somewhat widely distributed here and on the 

 Continent. 



2. Less strongly marked ; as a rule less widely distributed, 

 and therefore somewhat more open to doubt as to their identity 

 here and on the Continent, and perhaps partly on that account 

 not reported for Britain in Biibi Europcei, though probably cor- 

 rectly included in our list, are the following: — B. adornatus P. J. 

 Muell., B. horridica2ilis P. J. MuelL, B. hostiUs Muell. & Wirtg., 

 B. fusco-ater Weihe, B. divexiranms P. J. Muell., B. serpens 

 Weihe, B. Kaltenhachii Metsch., B. mimUiJiorus Wirtg. (or P. J. 

 Muell. ?), B. saxicolus P. J. Muell., B. tereticaulis P. J. Muell., 

 B. cyclophyllus Lindeb. All these names (except perhaps B. cyclo- 

 2)hyllus, which was first suggested as British by Babington) 

 have from time to time, and mostly more than once, been given 

 to British plants by Dr. Focke, though there seems no evidence 

 in Bubi Europai that he would still so apply them. As regards 

 cyclophyllus, we have followed Babington in substituting this 

 name for his conjungens, to be used in an aggregate sense for 

 forms of^ B. corylifolius Sm. other than the type (" a. sublustris 

 Lees " of London Catalogue, ed. x.). As however, there seems to 

 be considerable uncertainty about the right use of Lindeberg's 

 name, it may be wise to substitute conjungens Bab. as is done in 

 Bubi Europm. 



3. British plants for which names different from those in our 

 list are preferred in Bubi Europcei : — B. plmthostylus Genev., 

 B. Marshalli Focke & Eogers and its " b. semiglaber Eogers," 

 B. acutifrons Ley. Brief notes on these may be found of interest. 



B. plintliostylus Genev. is given in Bubi Europai as a synonym 

 of B. Beuteri E. Merc, but our plant, apparently known only
