60 MICROSCOPIC FUNai. 



constricted ; the apex is often pointed^ tliougli not 

 always so mucli as in our figure (fig. 74). 



Of otlier species found on allied plants we have 



not considered it necessary to give figures, or write 



much. The betony brand (P. Betonicce, DC.) does 



not seem to be common enough to be readily found 



by any one desiring to examine it for himself; 



and the same may be said of the iris brand 



(P. truncata, B. and Br.), the wood-sage brand 



(P. ScorodonicBj Lk-)^ ^^^ ^^^^ speedwell brand 



(P. Veronicarum, D C.) ; all of these are, however,, 



characterized by a distinct feature, or features, 



which have been considered of sufiicient importance 



to constitute them separate species. 



We have had occasion to refer incidentally to the 

 brand found on the under surface of the leaves of 

 the wood-anemone (P. Anemones , P.). This is one 

 of the earliest and commonest species. Go wherever 

 the wood-anemone abounds, in any of the woods 

 lying immediately to the north of the metropolis, 

 or any of the woods in Kent, and from March 

 to May it will not be difficult to find attenuated, 

 sickly-looking leaves, with the under surface covered 

 with the pustules of this brand, looking so like the 

 son of some fern (fig. 65) that it has been, and 

 still is, sometimes considered as such. In Ray's 

 " Synopsis'' (3rd edition, 1724), it is described in 

 company with the maidenhair and wall-rue ferns ; a 

 figure is given of it in the same work (t. iii. fig. 1), 

 and it is stated,—" this capillary was gathered by
