374 Mr. C. C. Babington on the British species of Arctium. 



when neither A. majus nor A. tomentosum is known, or when 

 only the lateral branches are examined, but when an intimate 

 acquaintance has been obtained with either of them, it is nearly 

 impossible that any doubt of the distinctness of those species can 

 continue to exist. 



The remarks to be found under A. tomentosum have shown 

 how differently the name A. Lappa has been applied by bota- 

 nical writers ; three out of our five species having been so called. 

 It is therefore desirable that the use of it should cease. It 

 also appears from the remarks of Fries (Nov. 263), that the 

 A. majics was certainly not the typical A. Lappa of Linnaeus ; 

 the name therefore cannot be properly employed to designate 

 this plant. 



The figure given by Tournefort to illustrate his genus Lappa 

 rather represents a head of the A. tomentosum than of A. majus 

 of this paper. The head named L, major by Gaertner is more 

 like my A. minus. 



A. majus is probably generally distributed in Britain, flower- 

 ing in August. 



My specimens are from Grosmont, Monmouthshire ; Mor- 

 diford, Herefordshire; Bluntisham, Hunts; Clonakilty, Cork. I 

 have seen it in several other places, but unfortunately my notes 

 concerning them have been lost. 



3. A. intermedium (Lange) ; heads racemose suhsessile ovate closed 

 in fruit slightly webbed, phyllaries equalling or exceeding the 

 florets subulate, inner row lanceolate shorter than the others, 

 subcylindrical upper part of the florets equalling the lower 

 part. 



A. intermedium, Lange, MS. in Herb. Bab. et litt. ; * Flora of Ben- 

 mark I Reichenb.fil. in Icon. Fl. Germ. xv. 54. t. 812. 



Stem and petioles floccose. Stem 3-4 feet high. Leaves 

 roundish-cordate, lowermost large. Central stem usually (?) 

 nodding and as well as the branches furnished with many nearly 

 sessile heads arranged in a racemose manner ; ending in three 

 heads placed close together. Heads moderately large, narrower 

 than those of A. majus, but appearing long from the ascending 

 direction of most of the phyllaries, usually slightly webbed. 

 Phyllaries purplish-green and subulate; their hooked points 

 purplish-yellow ; inner row purple at the end, lanceolate acute. 

 Florets cylindrical in their upper half, much resembling those of 

 A. majus but with different proportions, apparently persistent. 

 I have not seen the fruit. 



This plant may be known from all the others by having its
