Borrera Jlavicans discovered in Fruit near Penzance, 

 By Alfred Greenwood, Esq. 



I HAVE great pleasure in communicating the discovery of the fruit 

 of Borrera flavicans, which I found some days ago in an orchard, in 

 the neighbourhood of this town. I first brought home a single speci- 

 men, not being aware, at the time of gathering, that it was in fruit. 

 Afterwards Mr. Ralfs and myself succeeded in getting in the same 

 and surrounding orchards about seventeen more : most of these had 

 from one to three apothecia upon each of them, but a few were more 

 thickly fruited, and one specimen had, I believe, as many as one hun- 

 dred shields upon it. 



I understand there is only one recorded instance of the fruit of this 

 lichen having been previously found in Britain : this was a single 

 specimen gathered by Mr. liobb in the eastern part of the county. 

 It is now at Truro, in the herbarium of the Horticultural Society of 

 Cornwall. 



Even the barren specimens of the Borrera are valuable, from the 

 size which they attain in some of these orchards ; indeed, the fruit- 

 trees are so covered with different species of Parmelia, Usnea, &c., 

 that frequently but little of the bark can be seen, and many of the 

 smaller branches are quite destroyed by these epiphytes. The ap- 

 pearance thus given to the orchards struck me as peculiarly charac- 

 teristic of the country on ray first arrival from Essex, where the trees 

 are comparatively free from this nuisance, for such it is to the gardener, 

 although it adds to the beauty of the scenery, and is interesting to 

 the botanist, particularly when he finds among the lichens such a ra- 

 rity as Borrera flavicans in fruit.

Note on Hieracium pulmonarium. By Wm. Borrer, Esq., F.L.S. 



I AM glad to learn from the remarks in the ' Phytologist ' (ii. 442), 

 that Mr. Watson has come independently to the same conclusion as 

 myself respecting Hieracium pulmonarium of Smith, viz., that it is 

 identical with the plant which we regard as H. nigrescens of Willde- 

 now. I believe that Mr. Babington, too, now agrees with us. My 

 opinion has reference to the specimens which I gathered in 1810, from 

 rocks by the river Nevis (or Nivis) from one of which the figure in
