Triticum cristatum, Schreb. 



Area [15]. 



Incognit. Stated to have been found by George Don, 

 on steep banks and rocks by the sea-side, between Ar- 

 broath and Montrose (E. F.). The late Mr. N. J. Winch 

 gave me a specimen, said to have been received from Don, 

 and localized b}^ its label on the sands of Barrie. In a 

 letter from Sir W. C. Trevelyan, dated August 19, 1839, 

 he remarks that T. cristatum was then " abundant in 

 Lunan Bay, near Arbroath." But in 1848, Mr. Gardiner 

 asserted in his Flora of Forfarshire, that Don " alone has 

 found it." On which side is the error ? 



Triticum bitlorum, " Brig." 



Area [15]. 



Incognit. " The present is one of those plants gathered 

 by the late Mr. G. Don, which appear to have been over- 

 looked by other botanists. His label in Mr. Borrer's 

 herbarium, runs thus : ' Triticum alpinum, nova spec. — 

 it differs from the caninum by its short arista and upright 

 spikes, and from the repens by not running at the roots.' 

 No date is mentioned. It is thus clearly evident that he 

 distinguished it as a new species. The only British Tri- 

 ticum with which it can be confounded is T. caninum, from 

 which it may be distinguished by its leaves smooth on 

 both sides, its usually two-flowered spikelets, and its want 

 of the long awn ; it also appears to be a more slender 

 plant with narrower leaves " (Mr. Mitten, in London 

 Journal of Botany, viii. 588). The locality indicated is
