of the involucre seems to depend upon the comparative shortness of 

 the hairs with which it is clothed ; they are terminated by a pale por- 

 tion as in H. alpinum, but that part is very short, thus allowing their 

 lower part, which is black, to be much more distinctly seen. These 

 peculiar hairs will enable the plant to be distinguished from all forms 

 of H. murorum ; and in those specimens which produce more than 

 one flower, the very acute angle between the peduncles is a certain 

 character. I do not venture to give any strong opinion upon the spe- 

 cific claims of this plant, but am strongly inclined to think it distinct 

 from H. alpinum. I hope now to be allowed to say a few words on the 

 second plant referred to by Mr. Watson. During a visit to the West 

 Riding of Yorkshire in July last, I was shown by Mr. John Tatham, 

 jun., the plant that has for many years been called Hypochoeris ma- 

 culata by the botanists of that neighbourhood, growing upon rocks 

 near Settle, and had no hesitation in calling it a form of Hieracium 

 murorum. T have now re-examined specimens from that place, and 

 am fully confirmed in my opinion. I consider Mr. S. Gibson's H. 

 hypochceroides to be the same plant. This is far from being an un- 

 common plant, and is very often taken for the H. maculatum {Sm.) or 

 H, pulmonarium [Sm.], to which it is very closely allied, or the H. 

 pictum of authors. H. maculatum is, according to my view, a much 

 larger plant, with several stem-leaves, having a decurrent base to all 

 the leaves, thus referring it to H. sylvaticum. The plant called H. 

 pictum from the falls of the Ogwen is the H. rigidum, 7. pictum of 

 my Manual (p. 186), and quite distinct from all the forms of H. mu- 

 rorum or H, sylvaticum ; I possess it from Wastwater, Cumberland ; 

 Falls of the Ogwen, and near Llanberis, Caernarvonshire ; and from 

 near Thorngrafton, Northumberland. — C. C, Bahington ; St. JohrC'i

434, Note on the Weymouth Stations of Lathyrus Nissolia and Sa- 

 licornia radicans. In reference to Mr. Gibson's remarks on the plants 

 of Weymouth (Phytol. 735), and the Rev. A. Bloxam's note (Id. 775) 

 on the same subject, it may be worth mentioning that I was at Wey- 

 mouth in 1837, immediately after Mr. Bloxam's visit, when I found 

 Lathyrus Nissolia growing abundantly to the west of Portland Ferry, 

 and Salicornia radicans, also abundantly, on the ground newly re- 

 claimed from the Backwater. — T. Bell Salter ; Ryde, December, 1843. 



435. Note on the Hieraciums. You will perhaps allow me to thank 

 Mr. Watson for his information on the subject of the Hieracium (Phy- 

 tol. 801), Mr. Watson's remarks are very clear and satisfactory, and 

 there is little doubt of the plant sent by Mr. Tatham " to the Botani-
