ANNUAL KEPORT OF WATSOX EXCHANGE CLUB 25 



1914. — R. S. Standen. Though the aerial leaves soraetmies resemble 

 those of R. tripartitus, 1 should refer this, and all the other New 

 Forest plants 1 have seen, to B. lutarius. R. tripartitus, which 

 occurs in Cornwall an'd Co. Cork, may be readily distingushed by the 

 production of a number of very finely divided submerged leaves, the 

 segments of which are capillary. R. lutarius, on the other hand, 

 rarely produces any divided submerged leaves, and when these are 

 present they are few in number, less frequently forked, and have the 

 segments distinctly flattened. Usually there are also some tran- 

 sitional leaves present, and these I have not seen in R. tripartitus. — •

Viola hirta L., f. lactiflora Eeichb. Cadbury Eidge, Tickenham, 

 N; Somerset, v.c' 6, April 22 and Aug. 26, 191.3. Flowers pm-e 

 white. — Ida M. Roper. This plant is not the counterpart of the one 

 found on Cadbur}^ Camp, in the same district. Its surface is much 

 more hairy; its flowers are smaller, with much thinner narrower 

 petals ; its fruit is furnished with long shaggy hairs. The same form 

 grows sparingly in Banwell Wood, Somerset, and at Stokeinteignhead, 

 Devon. In 1914, Miss Livett very kindly sent me an assortment of 

 variegata and lactiflora forms from Cadbury, so that I might study 

 the capsules. I found all variegata capsules to have long, shaggy 

 hairs on the angles ; some lactiflora capsules were glabrous (as 

 described in British Violets, p. 24) ; some were slightly hairy, but 

 not shaggy. The name I applied to this form from Banwell Wood 

 and Stokeinteignhead is: — " F. hirta, var. hirsitta, f. lactiflora.'''' 

 Miss Roper's specimens — taken in flower, and again in fruit — make 

 violet-stud}^ a pleasure. — E. S. Gregory. 



V. Lloydii Jord., var. insignis Drabble. Abundant in oatfields, 

 Melvich, W. Sutherland, v.c. 108, July 15, 1915. Named by 

 Dr. Drabble. This beautiful pansy is common on the North coast, 

 in cultivated land ; but it is also probably native, as I saw it in wild 

 ground near Strathy and Altnaharra.- — Edward S. Marshall. 



Ruhus caeresiensis Sudre & Gravet, subsp. or var. integrihasis 

 Rogers. This is the plant represented in " Lond. Cat.," ed. x., by 



No. 444, ''integrihasis P. J. Muell. ? " ; The alteration of 



name suggested above is due to Dr. Focke's change of view. It was- 

 at his suggestion that we adopted the name R. integrihasis P. J. 

 Muell. (see Journ. Bot. 1890. p. 100) ; but now [see his Sp. Ruboi-um 

 (Rubi Europa?i) 1914, pp. 330, 331 (106, 107)] he associates om* 

 plant more closely with Sudre & Gravet's R. caeresiensis. His words- 

 (p. 330) are: " i?. integrihasis (cit. P. J. Muell.) Rogers ' Handb. 

 Brit. Rubi,' p. 24, forma R. caeresiensi arete affinis videtur " ; and 

 he adds (p. 331) "in planta Britannica (R. infegrihasi Rogers) 

 foliola potius obovata, aculei paullo longiores et robustiores sunt. 

 Stamina stylos superant. Petala roseola. R. caeresiensi sine dubio 

 magis affinis quam R. integrihasi. In sudHchen England." 1 have 

 not seen R. caeresiensis, which is reported only " in den belgischen 

 Ardennen." — W. M. Rogers. 



Saxifraga ^tei^nhergii Willd. Hort. " Caradon," Southampton, 

 Hants, May 30, 1915. Originally brought two years ago by 

 Mr, Arnold Eliott from Brandon Head, Co. Kerry, and transjjlanted
