little more than a page to the treatment of "Lichen." lu its 

 general trend, this is much like the discussion of Brunfels, so 

 that there is no occasion for reproducing it. A slight advance 

 is made, however, in that the caulicles are said to bear stellate 

 capitula, and the accompanying figure shows Marchavtia 

 polymorpJia with numerous carpocephala. The form spoken 

 of, he says, is collected in the month of July. 



At about this time, Jerome Bock carries the description of 

 Marchantia a little further.' In a paragraph* on ^'Hepatica 

 fontana sen Lichen" are words which may be translated thus: 

 "Lichen is a plant unfriendly to the summer sun, which de- 

 lights in shady and likewise moist places and therefore grows 

 only about the deeper and colder springs and on dewy rocks;

 together like scales and cohering. The plant creeps here and 

 there not differently from the way in which the lichen or im- 

 petigo spreads itself far and wide upon the skin. The root 

 of the Lichen is nothing other than a very fine, soft, matted 

 wool, by which it clings to the rocks; if you tear the herb away, 

 it is plainly observed to be green on one side, and furnished 

 with a many-parted, thick leaf, while, on the other, tliat by 

 which it is Joined to the rock, it is seen to be covered over in 

 the manner of a plaster. As the month of May approaches, 

 above the greater of those parts which we have spoken of as 

 leaves, there arise certain other very small leaflets, similar to 

 those of the mtiscus palustris, which raise themselves into
