52 ANNALS OF SCOTTISH NATURAL HISTORY 



true Lepidium Jiirtum of De Candolle (then known as TJilaspi 

 Jiirtum, Linn.) and our British plant to which he gave that 

 name. It was indeed Smith's imperfect definition of the 

 species that led Hooker to name the plant L. SmitJiii. 

 Hooker may not have been aware how closely related this 

 plant was to L. heteropkyllum of Bentham, of which our 

 British plant was subsequently made a variety by Grenier 

 and Godron as var. canescens, a name which in my opinion 

 still holds the field. It may be that the Lepidium hirtuin of 

 Smith's " Compendium " may be held to be a tenable name for 

 the Continental plant (the TJilaspi Jiirtum of Linnaeus), on 

 account of the description "siliculis hirtis," but the reference in 

 the "Compendium " to " E. B. 26, 1803," so far as the figure 

 of the plant goes, is incorrect and applies only to the fruit 

 figured on that plate ; the plant figured being, as already stated, 

 L. JieteropJiyllum, var. canescens. De Candolle in the 

 " Systema " gave a proper description of TJilaspi Jiirtum 

 under the name of Lepidium hirtum, and this appears to be 

 the first time that the plant was correctly diagnosed under 

 that name. 



No census numbers are given for Cotoneaster or 

 Agropyron acutum. May I suggest that in future editions 

 the names of plants which have been expunged should be 

 appended. I have failed to find the following plants, which 

 appeared in the eighth edition : Rosa systyla, var. Monsonice, 

 R. arvensis, var. Briggsii, LytJirum Salicaria, var. canescens, 

 Epilobium rosmarinifolium, Solidago Virgaurea, var. angnsti- 

 folia, Veronica peregrina and V. repens, Plantago argentca, 

 Carex prcecox, var. capitata, Botrychium lanceolatum, Coronilla, 

 Potamogeton polygonifolius, var. linearis, P. pcrfoliatns, var. 

 lanceolatus, Taxusbaccata,\?cc.fastigiata, and OpJn ys aranifera, 

 var. fucifera. The omission of these will probably not meet 

 with much adverse criticism.

NOTES ON THE NINTH EDITION OF THE LONDON CATALOGUE. 

 Since I wrote the foregoing notes, which were in type before the end of 

 last September, the fourth volume of the "Ke\v Index" has appeared, 

 and a Review of the " London Catalogue " has been printed in the 

 Bulletin of the Torrey Club. It is stated in the latter publication
