32 THE JOURNAL OF BOTANY 



Of a similar kind is a nuisance which may be of a more wide- 

 spread natm-e. In this part of the country, at any rate, it is the 

 custom of herbalists to travel (they are often railway guards) far 

 afield in search of plants used medicinally, and to root them up 

 and bring them home, and plant them in or near their houses, e. g. 

 on railway banks. This has a twofold artificial effect : (a) plants 

 are redistributed by man ; (b) laid open to extermination in their 

 original habitats. I have not seen this practice described before, 

 and it may serve to explain some present anomalies of distribution. 



Owing to one cause or another the following plants, moreover, 

 have disappeared from v.-c. 55 since 1886 : — Arabis Jdrsuta, 

 Dianthus deltoides, Sagina nodosa, Hypericum elodes, Trifolmm 

 glomeratum, Lathyrus palustris, Drosera rotundifolia, D. anglica, 

 Siitm latifoUum, CEnanthe silaifoUa, Antennaria dioica, Inula Puli- 

 caria, Anthemis nobilis, Senecio campestris, Arnoseris pusilla, Crepis 

 palitdosa, HypochcBvis glabra, Vaccinium Vitis-idaa, AnagalUs 

 tenella, Gentiana Pneumonanthe, Limosella aquatica, Orobanche 

 major, 0. purpurea, Pinguicula vulgaris, Mentha piperita, M. gen- 

 tilis, Calammtha Nepeta, Littorella juncea, Polygonum minus, 

 Bumex p)ulcher, Aristolochia Clematitis, Empetrum nigrum, Sjn- 

 ranthes autumnalis, Orchis ustulata (? an error), Habenaria bifolia, 

 Buscus aculeatus, Tofieldia palustris, Luzula Forsteri, Scirpus 

 pauciflorus, S. ccBspitosus, Bynchospora alba, Schoenus 7iigricans, 

 Carex dioica, G. filiformis, Asplenium Adiantum-nigrumr A. Tri- 

 cJiomanes,'-'' A. viride, Cystopteris fragilis, Lastraa Thelypteris, 

 Osmunda regalis, Lycopodium Selago, L. inundatum, L. clavatum, 

 Pilularia globulifera. 



These are mentioned here in case any of them are still known 

 to occur in localities in Leicestershire unknown to us, and as a 

 supplement to the list of Cryptogams cited as extinct here since 

 1886.t

Thanks are due to the Rev. W. Moyle Rogers, E. F. Linton, 

 Prof. E. Hackel, Messrs. J. E. Bagnall, Arthur Bennett, H. and J. 

 Groves, and J. W. White for naming several of the more critical 

 species. 



* Found where probably they have been planted recently, but not in truly 

 native habitats.
