not like Helenium at all, and essentially differs in the achenes 

 being hairy, not glabrous. The lower leaves are from J to | of 

 an inch, broad, not 6 to 8 inches, as in Helenium. Loudon, excel- 

 lent as he is, has not space to give an adequate description of the 

 plants, and he omitted the special, and indeed also the group 

 characters, the latter being Folia involucri, apice dilatata, = 

 spathulata, in Helenium, whereas in /. britannica, which is 

 in the section Enula Duby — ' Folia, involucri interiori apice 

 nciiminata.' 



The ' permanence ' of the trivial name, which is a botanical 

 rule, led me to choose the badly descriptive name paniculatum 

 for the broad-leaved Cotton Grass. It was called Linagrostis 

 paniculata before it was named Eriophorum lati folium Hoppe. 

 But a good many battles will have to be fought before we get 

 ■even our British plant names correctly.

ADDITIONAL NOTE. 



F. ARNOLD LEES, M.R.C.S., 



By way of rider to the foregoing, I would add certain facts, 

 privately communicated by G. C. Druce, which should prove 

 stimulating to those North of England Field Botanists, who are 

 inclined not to hide their light under a bushel. We have at 

 least three ' new,' undescribed British Plants, and two of them 

 Yorkshire species ! to which attention should be called, and 

 herbaria examined for with as little delay as possible, so the 

 results may appear in my Supplement. These are : — 



1. Montia lamprosperma Chamisso, the shining chestnut- 

 brown faintly reticulate seeds of which have been detected in 

 Leaf-bed deposits by Clement Reid, as well as the dull blacti 

 ones of the M. fontana, and the shining black, reticulate ones of 

 M. rivularis. Mr. Druce says M. lamprosperma seems a quite 

 distinct species, as in it the ' Flowers are free ' whereas they are 

 joined, not free in the hitherto accepted British forms. The 

 semina are very imperishable so that dried specimens on her- 

 barium sheets can be easily needled over for ripe non-cast seeds. 



2. Orobanche procera Koch (a form of reticulata, Wallroth), 

 which grows tall upon Thistle, Carduus eriophorus in West 

 Yorks., and ' Centaur ea ' (?) in Lincoln at Summer Castle. It is 

 to the obstinate acuteness of Mr. H. E. Craven, of Roundhay, 

 who forced its non-agreement in character with 0. elatior Sutt.,
