360 BOTANICAL REPORT. 



R. horridicaulis, P. J. Muell. On a hedge at the top 

 of the Cairns, Potisanooth, extending about one hundred yards, 

 F. JS. 'Davey. When Mr. Eogers published his invaluable 

 "Handbook of British E.ubi " (1900), Glamorgan and Brecon 

 were the only British counties where this striking plant was 

 known to occur. Almost as soon as it commences to flower, the 

 leaves are elaborately spotted and riddled through fungoid and 

 insect attacks, and before the fruit are ripe the whole bush wears 

 a very woe-begone appearance. 



Gaucalis latifolia, Linn. This plant, which was previously 

 known to have occurred in the counties of Devon, Somerset, 

 Gloucester, Hampshire, Herts, Cambridge, Bedford, and 

 Carmarthen, only, was found in June last by Miss Boucher in a 

 permanent pasture at Morval, near Looe. The Cornish locality 

 is an interesting one, as hitherto in this country it had been 

 looked upon as a weed of cornfields. 



Senecio Cineraria, DC. fS. maritimus, Reichb. Cineraria 

 maritima, Linn). Of undoubted garden origin, but perfectly 

 naturalized and more or less abundant on the cliffs above 

 Newquay harbour, where it appears to have been first noticed, 

 though only recently identified, by Br. Vignrs. By reason of 

 their attractive silvery grey foliage, the scores of plants which 

 have obtained a footing on the cliffs stand out among other 

 vegetation as very conspicuous objects. Torquay, in Devon, 

 and Killiney Bay, County Dublin, are the only other places in 

 the British Isles where this native of the Mediterranean is found 

 in anything approaching a naturalized state. Dr. Yigurs is of 

 opinion that S. albescens^ Burbidge and Colgan, a hybrid between 

 8. Cineraria, DC , and 8. Jacohcea, Linn., also grows above 

 Newqua}^ harbour. 



Gentiana lingulata, C. A. Agardh, var. prcecox, Townsend 

 (Murbeck). The type is not known to occur in Great Britain, 

 but the variety has been detected in several counties. I was able 

 to add it to our Cornish list in June last by finding it fairly 

 plentiful at Forth Towan. "Within a fortnight of my discovery 

 Mr. Edgar Richards sent me specimens gathered at Chapel Forth, 

 in the same parish, and about the same time Br. Vigurs detected 

 it at Newquay. From Gentiana Amarella, Linn., with which
