Forage or Packing Plants. 



Plantago major L. 1, 2, 4, 5. Hordeum distichon L. (culti- 

 Urtica dioica L. vated form). 



Agrostis alba L. 2, 4, 5. Pteris aquilina L. 1, 5. 



Avejia sativa L. (cultivated 

 form). 1, 2, 5. 



4. Site in Russell Steeet, Covent Garden. 



This site was formerly occupied by small tenements ; these 

 were pulled down as the leases expired, from 1901 to 1906. The 

 area of the site is comparatively limited, and the street is not a 

 wide one. An extensive forage-plant flora could scarcely be ex- 

 pected upon this site, and villa gardening is not likely to have 

 been practised in such a contracted area. The nearness of Covent 

 Garden Market might lead us to anticipate some interesting plants 

 from this source. None, however, were found. This confirms 

 the opinion that plants found in central town situations must 

 have been carried on to the spot, either by wind, birds, or by the 

 direct or indirect agency of man. 



Wind-distributed Plants. 



Epilobium angustifolium L. 1, Artemisia vulgaris L. 



2, 3, 5. Senecio vulgaris L. 2, 5. 



E. roseum Schreb. 1, 5. Cardmts arvensis Robson. 1, 2, 



Tussilago Farfara L. 1, 2, 3, 3. 



5. Salix {caprea?). 1,3. 

 Erigeron canadensis L. 1, 2, 3. 



Forage or Packing Plants. 

 Sinapis arvensis L. P. Convolvulus L. 1, 2, 5. 



Plantago inajor L. 1, 2, 3, 5. Agrostis alba L. 2, 3, 5. 

 Bumex obtusifolius L. 2. Poa annua L. 1, 2, 5. 



Polygonum PersicariaLi. 1,2. Lastrea Filix-mas 'Presl. 



A liverwort {Marchantia polymorpJia L.) bearing sporogonium 

 was found upon this site (see site 1). 



5. Site at the Corner of St. John's Street and Aylesbury 

 Street, Clerkenwell. 



This site, the property of the London County Council, was at 

 the time of my visit partially covered with road material, and 

 much of the uncovered part had been trodden down, and had 

 become turfed with Poa annua. The space is somewhat exten- 

 sive, and no doubt horses had stood upon it with their nose-bags, 

 both during the clearing of the site and in carting road material. 

 There is little doubt a more varied flora would have been found 

 upon this site if it had been visited before the space had been 

 covered by road material, and before it had been so much trodden 

 upon.
