and disused quarries, and appears to be indigenous. — C. B. Headly. 

 This is certainly the best record we have ; but the Clematis is 

 almost exclusively a chalk plant, and I fear we cannot claim it as 

 indigenous for Leicestershire, unless it should be found on the 

 oolite on the eastern border of the county. — W. B [ell] . 



Ranunculus tripartitus DO. Catsfield, East Sussex, v.-c 14, 

 1894. — Coll. E. S. Salmon. Comm. C. E. Salmon. A very 

 pretty but puzzling Batrachian. Named " pel tat us var. truncatus" 

 11 intermedins" and <; ololeucos " during the past three or four years 

 by well-known botanists. Major A. H. Wolley-Dod says that "the 

 almost free stipules remove it from any peltatus form, and its small 

 flowers are against this, too." R. ololeucos Lloyd must be very 

 similar to this plant, but the fruits of that species have longer 

 beaks, and the petals are wholly white. Prof. Corbiere very kindly 

 sent me a specimen. These Catsfield examples show well-developed 

 capillary submerged leaves, and appear to be large-flowered R. 

 tripartitus DC. The flowers were usually of Lenormandi size.

Viburnum Opulus L. (yellow-fruited form). Narborough, Lei- 

 cestershire, v.-c. 55, July, 1904. This form, which was first pointed 

 out to me by Mr. A. B. Jackson, is remarkable in that the berries 

 never become red, but retain their yellow colour until they fall. 

 The bushes from which these specimens were gathered presented a 

 striking contrast to those close by that bore berries of the normal 

 red colour, these latter being red practically as soon as the fruit is 

 formed. Beyond this characteristic there is no essential difference 

 between the fruit of the type-plant and that of the form, except, 

 perhaps, in that the berries of the latter may be said to be less 

 globose. — A. R. Horwood. The yellow-fruited Guelder-rose has 

 been known at Narborough Bogs for many years ; and it is quite 

 constant in the colour of its fruit. I know no other station. Is it 

 worthy of a varietal name or of being raised to a specific form ? 

 Some plants with less differentiation and constancy have been so 

 honoured. — W. B. A yellow-fruited form would seem to be of rare 

 occurrence. I have not found any reference to it in books, and 

 have it only from Ednaston, South Derbyshire. — E. P. L. 



Linaria supina Desf. Par, East Cornwall, v.-c. 2, Sept. 13th, 

 1905. This plant occurs in great abundance along the sandy beach 

 all around the harbour, along the St. Blazey-Fowey railway line, 

 and by the roadsides, and I think it has every claim to be considered 

 a native. It has been known as one of the common plants of that 

 district for quite sixty years. — F. H. Davey. 



Mimulus luteus L. [Langsdorjii Donn.] Walkham Vale, South 

 Devon, v.-c. 3, May 29th, 1905. This species is very plentiful on the 

 banks of the River Walkham. There are large masses of its yellow 

 blooms for a distance of seven or eight miles. In Mr. Archer

These 



specimens differ from those from the Dove in Derbyshire, in that 

 these are mostly upright and rooting from the two or three lower 

 nodes only, while the Derbyshire ones are more recumbent and
