WATSON EXCHANGE CLUB REPORT, 1905-6. 



[The following notes are extracted from the Report of the 



Watson Botanical Exchange Club for 1905-6. The Report con- 

 tains a " half-plate photo" of Polygala serpyllacea var. vincoides, 



a plant described in this Journal for 1906, p. 34. The notes 

 as usual display those differences of opinion between competent 

 botanists which are apt to puzzle the confiding beginner ; and the 

 matter is further complicated by the fact that in some cases the 

 same plants receive further (and differing) comments in the Report 

 of the Botanical Exchange Club for the same year : see, for ex- 

 ample, the notes in each Report on specimens of Lepidium hetero- 

 phyJlum from Northamptonshire : " Viola Ritiniana Reichb., forma 

 minor," which Mr. Druce (Rep. Bot. Exch. Club) agrees with Mrs. 

 Gregory in thinking " should certainly equal V. flavicomis Forster," 

 Mr. Marshall thinks (Rept. Watson Club) u merely a starved state, 

 and not deserving a special name." Those who are doubtful as to 

 the specific distinctness of certain " critical " plants will find their 

 scepticism confirmed by the notes on Euphrasia. 



It may be worth while to call attention to a not infrequent 

 misuse of the term " type/' of which an example is found in the 

 statement that Gloucestershire specimens of Carex Leersii are 

 "exactly like the type-specimen in Herb. Brit. Mus." A " type- 

 specimen, " as defined by Mr. Jackson in his Glossary, is u the 

 original specimen from which a description was drawn up," and 

 this is undoubtedly the meaning of the phrase in its strict sense. 

 In the present instance the specimens of C. Leersii in the National 

 Herbarium may be described as authentic, as they were collected 

 and determined by F. Schultz and distributed in " F. Schultz and 

 F. Winter, Herbarium Normale," Cent. 2, n. 173 ; but they are not 

 " type." 



May we suggest that it would be useful if the Reports of both 

 Exchange Clubs included a list of the addresses of their members ? 

 This was done in the early days of the Botanical Exchange Club, 

 which now does not even give the names of those belonging to 

 it. — Ed. Journ. Bot.] 



Clematis Vitalba Lu Martinshaw Wood, Leicestershire, v.c 55, 

 Sept. 1905. I am sending a few specimens of Clematis, as it has 

 hitherto been recorded as naturalized, or an escape, for Leicester- 

 shire. In the Martinshaw it is found in great plenty on the rocks
