show that Mr. Baines and myself are not alone in considering Avena alpina and pra- 

 tensis to be the same species, I copy the following from a note that I received from 

 Mr. Tatham a short time ago. " Dost thou think there is any real difference between 

 Avena pratensis and alpina ? If the panicle being compound or simple is any distinc- 

 tion, we have them both, but I think they are one and the same." Mr. Tatham fur- 

 ther says in a note dated September 9, 1841, " I do not think the roughness or smooth- 

 ness of the sheaths of Avena alpina is at all to be depended on, for I have seen both 

 extremes in the same tuft." — Id. 



83. Sedum rupestre, (Phytol. 68). Your correspondent says " no doubt introduced 

 originally." Why he should suppose so I know not. The plant is by no means local 

 in its distribution upon the rocks, and frequently occurs in the most inaccessible parts. 

 — Leo. H. Grindon ; Manchester, October 20, 1841. 



84. Habenaria chlorantha, (Id. 70). The species which I have always considered 

 to be the bifolia, is very common in woods and shady places about Bristol. Near But- 

 combe, Somersetshire, as well as at Horfield and Stapleton, it grows in most luxuriant 

 profusion. The chlorantha I have seen but once, viz. under Cook's Folly — one of the 

 localities quoted for it. Does it really deserve to rank higher than as a variety of H. 

 bifolia ? — Id. 



85. Anagallis cm'ulea, (Id. 76). I thought botanists were long since agreed as to 

 this plant being only a variety of A. arvensis. It grows in cornfields upon the lias at 

 Knowle and Horfield, near Bristol, and ouIt/ on the lias, never appearing elsewhere 

 with blue flowers, or retaining its colour when sown in ordinaiy garden soil, as I have 

 myself proved.— ZtZ. 



86. Equisetum fiuviatile. I gathered a curious variety of this plant in August, 

 1841, on the bank of the Manchester and Sheffield railway, near Glossip. This spe- 

 cimen was leafy and in good fruit ; the catkin was topped by a prolongation of the 

 frond about twelve inches in length. Mr. Francis, in his ' History of British Ferns,' 

 mentions a similar specimen having been gathered near Bangor, in 1836, — Joseph 

 Sidebotham ; Manchester, November 4, 1841. 



87. Plants observed in the Neighbourhood of Shoreham, Stissex. During the early 

 part of July, 1838, my brother and myself spent some days at Shoreham, on the coast 

 of Sussex, principally with the view of collecting a few plants from that locality. 

 Amongst the great mass of shingle thrown up by the sea, we found Vicia lutea very 

 abundant. Galeopsis Ladanum, specimens very small, scarcely exceeding 6 inches in 

 height. Glaucium luteum, abundantly displaying its large bright yellow flowers to 

 the saline breeze. A few solitary plants of Crambe maritima (which had not flowered 

 that season) between the pier-head and the preventive station ; and in the same loca- 

 lity we observed a few patches of Crithmum maritimum, just coming into flower. Se- 

 dum anglicum, plentiful, displaying its beautiful white starry flowers out of reach of 

 the shingle ; as was also the case with Statice Armeria, Frankenia laevis, Arenaria ma- 

 rina and Ervum hirsutum. Ruppia maritima, very plentiful in the small pools of salt 

 water in the marshes adjoining, (towards Worthing); and on their margins Triglochin 

 maritimum, CEnanthe pimpinelloides, Glaux maritima and Juncus acutus, and where 

 the tide flows over, Salicornia herbacea and Atriplex portulacoides, very abundant. 

 At the harbour's mouth, against the piers, we found a few plants of Cakile maritima 

 and Statice spathulata. Centaurea Calcitrapa abundant. Linum angustifolium very 

 abundant at the foot of the cliff's towards Brighton, near Kingston. RottboUia incur- 

 vata, on the sands just above h'gh-water mark. Cheuopodium maritimum and Silene
