and rigour. The dictamniises known as eau- 

 casic'us and tanritns are, lioAvover, nobler 

 than the otlier forms of the eommon one, 

 which is named D. albns in the Kew 

 ''Hand List," althongh best known to us 

 as D. Fraxinella, Some doubt has been 

 throw^n on the behef that the dictamnuses 

 emit an inflammable vapour, which will 

 ignite on a calm evening if a lit match is 

 applied to the flowers or upper portions of 

 tlie stems. This is, however, a well-proved 

 fact, and it renders these handsome border 

 flowers more interesting than they would 

 otherwise be. Yet they deserve notice for 

 their beauty. By the way, they are easily 



feet in such a border. It is not nearly so 

 stiff wdien in flower as our native burnet, 

 and the spikes look quite light and elegant, 

 it sows its seeds freely enough, and ako 

 increases by undergroimd runners, so that 

 it can hold its own well, and requires to 

 be watched, indeed, lest it injures some of 

 its neighbours 



Geranium pra.tense. 



It may appear superfluous to write of the 

 native craneshill called Geranium pratense. 

 But it would seem that there is a good 

 chance of it giving a considerable diver- 

 sity of colouring if some attention were

depth of tone, there would surely he 

 some encoiiragement for seedling raisers, 

 crossei's and liybi'idisers to persevere.

One finds that this tall liorder or wild

 to know that so many people are unac-
