better if starred. B. secalinns itself is probably only a 

 colonist. 



The census numbers are brought as far as possible up to 

 date : but would it not be well to put a note of interrogation 

 after the figure in the cases of Carex Davalliana, which has 

 long ago been extinct in its Somersetshire station ; Senecio 

 palustris, which is cited for eight counties ; Senecio pahtdosus, 

 which is recorded for three counties ; Holosteum umbellaturn, 

 which is credited with the same number. Poa laxa and Poa 

 stricta are recorded for three counties ; are these correct ? 

 Vicia Icevigata is starred, but I suppose there was no doubt 

 of the plant being a native at Weymouth. It has long been 

 sought for in vain. Probably V. hybrida was an introduction 

 at Glastonbury, where it no longer occurs. I have had it 

 sent me from one or two places as a cornfield weed in cen- 

 tral England. 



Why should the genus Falcaria and the genus Fagopyrum 

 not be separately numbered ? It appears to be the general 

 plan when the plant or plants in a genus are starred to star 

 the generic name also, but this is not done in the case of 

 Crocus, Panicuin, and Setaria. 



No two botanists would probably agree as to what casual 

 plants should be inserted in the Catalogue. Some of us 

 think that when plants such as Archangelica, Arabis Turrita, 

 Prenanthcs, etc., are admitted, we need not be squeamish 

 about finding a place for Erysimum repandum, Silene 

 dichotoma, Trigonella ccernlea, and Aster paniculatus. 



When we have varieties such as Hippuris, var. fluviatilis^ 

 Weber, admitted, it appears reasonable that many others 

 might be added. Among these may be mentioned Papaver 

 Rhccas, var. Pryorii ; Cardamine pratensis, var. pains tris 

 (Petermann) ; Malva sylvestris, var. lasiocarpa (a hairy fruited 

 variety which I have seen in three or four counties) ; a narrow- 

 leaved form of Vicia gemella, which is often mistaken for V. 

 gracilis (it may be distinguished as var. tenuissimd] ; the 

 ebracteate form of Heliantkum Breweri, viz. var. ebracteata ; 

 Crepis nicceensis, var. eglandulosa, Crep. ; Geranium sylvaticum, 

 vzx.parviflorum, Blytt; Crepis virens,vdx. agrestis ; ZannicJiellia 

 arvensis, var. repens (Boenn.) ; Anemone nemorosa, var. ccemlea, 

 DC.; Sherardia arvensis, we. Walravenii; the pubescent variety
