'296 Botany. 



and Artemisia maritima was found abundantly at Burrowhead, near Cragleton 

 Castle, and at St Mary's Isle, more sparingly in a few other places between the 

 first and second stations. The neighbourhood of Kirkcudbright is quoted as a 

 Scotch station for Lathyrus latifolius. It was accordingly found abundantly in 

 the woods at St Mary's Isle, but it is known certainly to have been introduced 

 many years ago. Solanum nigrum, which is by no means a common plant in 

 Scotland, and perhaps only occurs where introduced, was observed in dense 

 masses growing in the neighbourhood of Sandhead, and to the northward of Port 

 William, on three or four spots where sea-weed had formerly been laid up to 

 dry. 



The pools were examined on the whole route, and inquiry made everywhere 

 for Cladium mariscus, but no trace of it was seen or heard of ; and a suspicion 

 necessarily arose regarding the correctness of a statement, that the plant is abund- 

 ant in Galloway. Does it exist there at all ? Has Galloway been inadvertently 

 substituted for Galway ? There it does grow R. G. 



Calothrix distorta, Hook. Br. Flor. ii. 369 — This pretty and rather rare Al- 

 gae was found by Mr Selby and myself in Newham Lough, August 15, 1836. 

 It is a new acquisition to the Flora of Northumberland G. J. 



Jungermannia Machaii — This plant was observed growing on some rocks by 

 the sea side near Drumore, Galloway, in the month of August last. It is a rare 

 species, confined to the British Islands, and no Scottish station for it has been 

 hitherto placed on record — R. K. G. 



The genus Rub us In Koch's Synopsis Flora Germanica et Helvetia, re- 

 cently published, the species of this most difficult genus are reduced to five, viz. 

 R. Idceus, fruticosus, casius, saxatilis, and chamcemorus. The number of spe- 

 cies in the British Flora is thirteen. The German and Swiss roses are all re- 

 ferred by Koch to seventeen species — R. K. G. 



The genus Adoxa — This plant, referred by some botanists to Saxifragecc, by 

 others .to Araliacea, is placed by Koch among the Caprifoliacea. He observes 

 that it is closely allied to Sambucus in the parts of fructification — R. K. G.
