it was long- confounded, this plant differs by its more dwarfed 

 stature, its earlier time of flowering, and by its calyx being 

 oftener 4-fid than 5-lid, with the segments slightly shorter than 

 in G. Amorelh. G. Jingiilata, var. prcecox commences to flower 

 early in May, and by the first week in July leaves and flowers 

 have disappeared and the capsules are perfectly ripe ; whereas by 

 that time G. Amarella has not made its appearance. In " Acti 

 Horti Bergiani " (8ee "Journal of Botany," 1894, pp. 1-4), 

 Herr Svante Murbeck expresses the opinion that G. lingulata has 

 become differentiated from G. Amarella since the last glacial 

 epoch.

 apjDarently widely distributed throughout Great Britain. 



E ? During the last week in June 1 found a very 



handsome eyebright of the Rostkoviana type on the hillside at 

 Forth Towan. A week or two later I found it rather sparingly 

 on Connor Downs, and about the same time Mr. Tresidder 

 reported it from Goonhavern, Mr. Marshall, to whom fresh 

 specimens were sent, confessed that the plant was new to him, 

 and that it would not come under any described British form. 

 It is shorter and much less branched than E. Rostlcoviana, Hayne, 

 and has a larger and deeper violet-coloured corolla than I have 

 seen in any other eyebright. Specimens sent to Prof. Wettstein, 

 of Prague, the well-known authority on the genus, have not yet 

 elicited a reply. 



Salix lutescens, Kern. {S. aurita x cinereaj. This hybrid 

 willow was found by me along the banks of the reservoir, in the 

 parish of Mabe, early in September. As the willows of Devon 

 have not yet been thoroughly worked, I am unable to say if this 

 recent addition to the flora of Cornwall has been found in the 

 neighbouring county. 



Potamogeton interruptus, Kit. fP.flabellatus, Bab.) In 

 the Supplement to the "Journal of Botany," for August last, 

 Mr. Arthur Bennett includes this species for West Cornwall. In 

 rei)ly to a letter, Mr. Bennett informed me that the plant was 

 found in a ditch near Penzance, in August, 1875, by the late 

 Mrs. E. A. Lomax, and was distributed by the Botanical
