modestum, Jord., and P. Lamottei, Boreau. Unless I am under 

 a misapprehension^ the common dubium of our country is iden- 

 tical with the first of these. Of our plant the capsule is oblong- 

 cylindrical in shape, broadest rather above the middle, narrowed 

 very gradually till within a short distance of the base, the stig- 

 matiferous disc (in the mature capsule) flattish at the sides, but 

 raised at the centre into a rounded protuberance, its crenations in- 

 conspicuous, and the stigmas are from five to seven in number, and 

 fall short of the edge of the disc by a little space. In P. Lecoguii 

 the capsule is exceedingly similar in shape, but the stigraatiferous 

 disc is more convex, its crenations much more conspicuous and 

 decided, and the stigmas are eight or nine in number, and reach 

 quite to the edge of the disc. It was originally described from the 

 centre of France, and has since been met with by Messrs. Crepin 

 and Graret in several stations in Belgium. It appears to have a 

 preference for calcareous districts, as is stated to be also the case 

 with P. modestum. 



" Fumaria pallidiflora, Jordan. A study of the descriptions in 

 Boreau's Flora, and comparison with French specimens, shows 

 me that the Fumai^ia of which I spoke in a recent note as the 

 normal form of capreolata is identical with this plant. The true 

 F. speciosa, Jordan, is very closely allied to it, but has larger, 

 deeper-coloured flowers, and broader based fruit. F. pallidiflora 

 and Borm are no doubt both of them both frequent and widely 

 diffused in Britain, and I hope that by next year we shall be able 

 to get a sufficient stock to meet the requirements of our friends. 

 Both of them are sometimes plentiful enough in this neighbour- 

 hood, but they are uncertain in their ajapearance, and last year 

 I only dried a small supply of Borm. Barbarea intermedia, 

 Boreau, has been met with by Mr. More in Ireland, in county 

 Armagh. He writes respecting it, ' My specimens were collected 

 in 1844, and it is to Mr. Borrer that I am indebted for the name. 

 They differ in no respect whatever from what you gent me from 

 Thirsk last year, labelled Hulme, Lancashire, by Mr. Hardy, but 

 I cannot answer for the plant being a true native. All the de- 

 terminable specimens were gathered in cultivated fields, where it 

 was an abundant weed, and I think some younger plants from 

 roadsides adjoining were the same. I half suspect that the plant 

 is sometimes grown in gardens.'
