ALIEN PLANTS 105 



*Triticum yEgilops, Beaiiv. {^gilops candata, L.). Two fine clumps, 

 at Leith. 



*T. caudatum, G. and G. One plant, Leith, in 1904. This plant 

 was in error recorded as T. speitoides, var. Aucheri^ Aschers. 

 and Grbn. in my paper on 'Alien Plants' in the "Ann. Scot. 

 Nat. Hist." for April 1905. 



*T. crassum. Ait. and Hemsley, nov. var. oligochaetum, HackeL 

 Plentiful at Slateford, several at Gorgie and Leith. Identified 

 by Professor Hackel, who adds the following remark : " Differt 

 a typo glumis fertilibus scabridis non tomentellis, aristis 

 glumarum fertilium in spicula terminali elongatis, in spiculis 

 lateralibus brevissimis vel ad mucronem redactis. Spica quam 

 ilia typi minus crassa." 



*T. peregrinum, Hackel^ nov. spec. Once found at Leith and once 

 at Slateford in 1906. 



For convenience the description of this plant, by Professor 

 Hackel, is reproduced below to accompany the figure (Plate HL), 

 which is from a dried specimen grown from the seed of one of the 

 original plants.
