BOTANICAL REPORT. 365 



Potentilla Tormentilla, Neck., var. sciaphila, Zimmeter. 

 A plant found by me on Wheal Clifford Downs and Carnmarth, 

 Gwennap, is so placed by Mr. Bennett, who tells me it agrees 

 with an authentic British specimen so named by Dr. Wolf, who 

 is monographing the genus. The plant is generally more 

 compact than the type, with short, many-flowered branches. 

 The radical leaves are mostly small, almost circular in outline, 

 generally ternate, but sometimes with four broadly wedge-shaped 

 leaflets, which overlap. The achenes are less keeled than in the 

 type, and (when fresh) have a number of pale longitudinal 

 markings. The divisions of the epicalyx are more abrubtly 

 contracted at the base, and more conspicuously 3-nerved. Br. 

 Vigurs has recently found the plant at Retew, in the parish of St. 

 Enoder. 



Crepis Yirens, Linn., var. agrestis, Koch. (C. agredis, 

 Wald. & Kit.) This variety occurs in the late summer and 

 autumn in potato and turnij) flelds. In the neighbourhood of 

 Ponsanooth it is very common, and I have no doubt it will be 

 found in most parts of the county. It is a stout, erect plant, 

 from two to three feet high, with larger anthodes than in C. 

 vhrns, and the phyliaries are covered with dark glandular 

 hairs. 



Leontodon autumnalis, Linn., var. simplex, Duby. A 

 dwarf plant with generally a monocephalous scape. It is very 

 frequent in the short turf on Connor Downs. 



Nepeta Glechoma, Benth., var. parviflora, Benth. Easily 

 recognised by the corolla tube being but little longer than the 

 calyx, and by its smaller, hispid-pubescent foliage. Newquay, 

 C. C. Vigurs. Perranzabuloe, TF. Tresidder. Perrauporth, J. TF. 

 Jones. Ponsanooth, F. II. Bavey. 



Galeopsis Tetrahit, Linn., var. biMa (Boenn.) Plant 

 much smaller than the type, with a shorter corolla, the lower 

 lobe of which is notched. Newquay, C. C. Vigurs. Goonhavern 

 and Perranwell, Perranzabuloe, W. Tresidder. Parishes of St. 

 Gluvias, Perranarworthal, Gwennap, Stithians and Mabe, F. H. 

 Bavey. 



Polygonum Persicaria, Linn., var. prostratum, Breb. 

 This variety, marked by its decumbent stems and short sj)ikes of
