32 A LIST OF BRITISH UOSKS 



I have not a single specimen in my herbarium referable to type 

 B. coriifolia, and I think only two of the British specimens in 

 Deseglise's herbarium belong to it. V.-c. 58, 62, 65, 69 ?. 



E. FRUTETORUM Bess. Euum. PI. Volh. Pod. p. 18. Eegarded 

 by some authors as synonymous with the type ; this I think 

 represents the bulk of our Bi-itish B. coriifolia. Besser's descrip- 

 tion says its leaflets have the " serratures subgeminate," and con- 

 tinental authors classify them as somewhat biserrate, as well as 

 less hairy than in B. coriifolia. I have several specimens named 

 B. coriifolia var. suhhiserrata Borb. by Sudre, which variety is 

 practically synonymous with B. frutetorum, the difference, if any, 

 lying in its more globose fruit. Dingier labels all of them that he 

 has seen, except one from Cheshire, " var. subcollina Chr. or near 

 it," in spite of their having very rising or suberect sepals. Both 

 Sudre and Dingier include examples with subglabrous or only 

 hispid styles, and long peduncles, which I follow Crepin in 

 placing to the Dumeiorum group (see under B. suhmitis, p. 22), 

 but I admit that, with the exception of the style clothing, some of 

 these are identical with those referred to B. frutetonim, and it is 

 difficult to draw any line. V.-c. 3, 17, 40 ?, 58, 92. 



E. iMPLEXA Gren. Eev. El. Jur. p. 62. If we confine this, as 

 Grenier defined it, to a form of B. coriifolia with glabrous leaflets, 

 or the midribs alone hairy, I do not think it occurs in Britain, 

 but two Cheshire specimens, for which I know no other name, 

 having the lateral nerves hairy, may be admissible, unless they 

 are B. coriifolia var. liicida Braiick. They have somewhat rising 

 sepals. Forms with spreading or reflexed sepals, which have 

 been referred here, are rejected, as they belong to the next sub- 

 group. A specimen from Buckie Braes, Perth (Barclay), has only 

 spreading-erect sepals and slightly biserrate leaflets and may 

 belong to the Subcollincs. V.-c 58, Perth ?. 



Leaflets Biserrate. 



E. Bakeri Desegl. in Journ. Bot. 1864, p. 267. Following the 

 description and type-specimen, typical plants of this species 

 should have their leaflets glabrous above, more or less glandular 

 beneath, and narrowed towards the base, smooth or rarely glan- 

 dular peduncles, ovoid fruit and spreading-erect sepals. Beyond 

 some of the author's specimens, I have only seen three so 

 labelled, all from Perth (Barclay). One of .these, No. 15, which I 

 passed in Wats. Exch. Club Eept. 1908, has glabrous leaflets, and 

 therefore is a Glauca and not a Coriifolia form (see under B. venosa, 

 p. 29). One of the other two was labelled var. Lintoni by Mr. 

 Barclay, presumably on account of its smooth peduncles, but 

 these and its ovoid fruit are normal for B. Bakeri, to which I 

 place it. V.-c. 62, 67, 69 ?, 88. 



E. coriifolia var. Lintoni Scheutz in Journ. Bot. 1888, p. 68. 

 The description and specimens of this variety are not very con- 

 clusive. It may perhaps be regarded as intermediate l^etween 

 B. Bakeri and B. celerata, differing from the former in its sub-
