372 THE PLOEA OF CORinVALL. 



Gwennap, by Mr. W. Rowe, and from near Perranporth, by 

 Mrs. E. Pierson. A native of western North Ajnerica, it has 

 long shown permanency in several of the eastern and northern 

 counties, but has been very tardy in extending its range 

 westward. 



At Hayle, Canon Rogers has also found the Hispid Mallow 

 [Althcea hirsuta, Linn), one of the rarest items in the British 

 flora. In common with some of the other plants already 

 mentioned, it has not yet honoured the soil of Devon. 



To the same indefatigable worker must the next plant on 

 my list be credited. Long known to occur in Devon, it was not 

 until Canon Rogers found it west of Carbis Bay that anyone 

 suspected the presence in Cornwall of Medicago minima, Desr. It 

 is very probable it has been overlooked in other parts of the 

 county, and a diligent search should be made for it. 



Between Penzance and Gulval Messrs. E. S. and C. E. 

 Salmon, of Reigate, have gathered Melilotus indica, All., a plant 

 said to have occurred near Liverpool, and to be not uncommon 

 about Battersea and Wandsworth. No one has yet found it in 

 Devon, and this is a welcome confirmation of Mr. W. A. 

 Glasson's record for the Eastern Grreen twelve years ago. 



As is the case with Penzance, Hayle, Par, Looe, and other 

 sea-port towns, many agents contribute to swell the richness of 

 the flora of Falmouth. For the latest addition we are indebted 

 to Mr. J. Lawson. In May last Mr. Lawson sent me for 

 identification a plant which he said was not uncommon at one 

 place on the out.skirts of the town. Careful examination proved 

 it to be a Trifolium, allied to ochroleucon and squamosum, but its 

 specific identify is still uncertain. Nothing like it can be found 

 in the herbariums at Kew and South Kensington Natural History 

 Museu.m, where it was taken for comparison. 



As ballast plants, Mr. Tellam reports Lathyrus hirsutus, 

 Linn., and Z, tuherosUs, Linn., from Par. Both are new to 

 Cornwall and both have yet to be found in the adjacent county. 



The first plant to be noticed under the Natural Order 

 Rosacem is Spiraea salicifolia, Linn. In a paper on " The Botany 

 of Polperro and its neighbourhood," in the Annual Report of the 

 Royal Cornwall Polytechnic Society for 1848, Mr. T. Q. Couch
