We may also observe that a very interesting 

 species may be found on several species of St. 

 John^s wort [Hypericum), but especially on the 

 under surface of the leaves of the Tutsan^ covering 

 them with its golden-coloured spores (plate VIII. 

 fig. 174). Another occurs on the leaves of some 

 of the wild garlics {Allium) ; one is not uncommon 

 on some of the stitchworts ; another on saxifrages ; 

 another on willow-herbs [Eiyilohium) , and one on the 

 leaves of the cowberry. All of these have yellowish 

 spores, A species with brown spores occurs on 

 sea lavender {Statice), Space to write on our own 

 partj and patience to read on the part of others^ 

 induce us to dismiss all these species with the 

 bare allusion to them and the plants on which 

 they may be found. Some of them may occur in 

 one locality and some in another^ and enough has 

 perhaps been said to enable any one to place any 

 that he may find in the proper genus^ if not with 

 the scientific name. 



From the numerous instances we have met with 

 of persons wholly disinterested in the subject,, 

 collecting and making inquiries concerning the 

 bright orange patches next to be referred to^ we 

 are led to conclude that most persons have^ at 

 least^ seen them. These patches of orange-coloured 

 powder burst through the cuticle^ and appear on 

 the young branches of wild roses^ extending some- 

 times for two or three inches in length (plate VII. 

 fig. 147)_, and form one of the most beautiful and
