will detach themselves either when the root-fibre has reached the soft 

 ground, or when the parent leaf has decayed. See Hopkirk's Fl, 

 Glott. p. 83; Fl. Berw. ii. p. 296 ; Don's Gard. Diet. i. p. 171 ;

37. C. AMARA. "Watery places in denes, on burn-sides, and at 

 the base of hills, not uncommon. — B. In the Pease and Dunglass 

 deans, and in Blackbuin-rig dean : in Langton woods, and at the foot 

 of Cockbum-law. In a ditch near the Sow-mire at Swinton, J. 

 Hardy ; and on the banks of the Tweed at Birgham, Dr. R. D. 

 Thomson. — R. Banks of the Tweed near Kelso, Dr. F. Douglas. — 

 N. In the ravine above Akeld or Akolde. — June. 



38. Sisymbrium officinale. Wastes and road-sides, common. 

 — June- August. 



39. S. iRio. On the walls of Berwick-upon-Tweed, John Ray. 

 It grows in profusion about the Ness-gate, and there only ; and there, 

 for many years, it has scattered its numerous seeds on the heaps of 

 manure collected from the streets. This manure is carried away an- 

 nually and spread over the fields in the Liberties ; yet a plant of the 

 Irio has never been seen in any of these fields. This is a curious 

 fact, — more especially when viewed in connection with another. In 

 1847 a large quantity of earth was taken from an adjoining field, 

 where the Irio was never known to grow, and used to make the em- 

 bankment on which the station of the N. British Railway partly 

 stands. The Irio grew up on front of the bank in great profusion 

 immediately. It rapidly, however, decreased ; — oidy a few specimens 

 were noticed in 1849, and in 1851 not an indi^ddual remained. Sin- 

 gularly enough, this plant, which refuses to colonize, is about the most 

 profuse in seed of its tribe.
