Art. CCXLVIII. — Additional Plants found about Saffron Walden, 

 during the Summer of 1844 ; with Remarks on some of the 

 Species. By G. S. Gibson, Esq. 



Papaver somniferum. Ditch-banks, &c., rare ; an outcast from 

 gardens. 



Hypericum maculatum. Woods and moist hedge-banks in several 

 places. It appears clearly distinct from either H. perforatum or H. 

 quadrangulum, for which it is probably often overlooked ; but I can- 

 not think it more than a slight variety of H, dubium, having the broad, 

 obtuse, reflexed sepals mucronated instead of entire, and the petals 

 slightly streaked with purple. Probably it is not an uncommon plant 

 in most parts of England. 



Ruhus Koehleri. Hedges on the Ashdon-road. 



R. villicaulis. How-wood, Littlebury. 



This genus is so intricate, and such a remarkable diversity of opin- 

 ion exists as to the distinction of the species, and also as to which 

 species many of the variable forms are to be referred ; that I feel some 

 hesitation in giving names to them : yet those who have paid atten- 

 tion to the subject, must feel satisfied that there are a considerable 

 number of really separate species, and I cannot doubt that these two 

 are among the number. They agree with authentic specimens so 

 named by E. Lees, the great authority for this genus, which I have 

 received from the Botanical Society of London. I wish the attention 

 of botanists were more drawn to this tribe of plants, which requires 

 much further examination, but is too often passed by, either as unde- 

 serving of notice, or so intricate as to render the investigation of it a 

 hopeless task. But surely it deserves equal attention with other ge- 

 nera ; and the only way to clear up the difficulties connected with it, 

 can be by patient observation in various localities. 



Rosa systyla. Hedges, rare. 



R. inodora and micrantha f Not common. Introduced here on 

 the authority of Joshua Clarke. 



Galium Vaillantii. This plant, which I believe has not been hi- 

 therto noticed in Britain, was discovered by myself last month, in a 

 field adjoining this town ; it grew in tolerable abundance, and was 

 intermixed with G. Aparine. The crop on one part of the field was 

 barley, on the other, clover, grown from English seed. It was found 

 among both, and therefore could not have been recently introduced 

 with the seed ; independently of which, it is the opinion of the grow-
