OF TREES AND PLANTS. 



bufhy and tangled in its younger ftate. In its older one it is 

 more open and lefs implicated, as it grows in length and thick- 

 nefs. Thofe that bear the fructifications are robuft, with dicho- 

 tomous branches, fome with finer, and others with more rigid 

 points, or fibrils. Thefe Micheli has figured four different times 

 as four different plants. One of thefe, which is the firfl he men- 

 tions, he calls the knotty Vfnea (ivj. The knots are only the fruc- 

 tifications, which before they expand into the form of difhes, 

 are orbicular, and look like knots. The fructifications of the 

 alpine crejled coralline Mofs are formed after the fame manner. 

 He has drawn it more after nature than Dilhnius. The fecond 

 is that I have referred to among the Synonyms, ufed by the judici- 

 ous Haller. It has longer and finer points. Dillenlus acquaints 

 us he never obferved it in all his fearches *. The third is with 

 rigid (x), and the fourth with fmall (y) t fibrils at the ends. It 

 is in all thefe forms on the face of the fame fleep and lofty pre- 

 cipices. It is one and the fame plant under all thefe appearances 

 in its ftate of fructification. An over-fondnefs for being the au- 

 thor of the difcovery of new and unknown plants, natural to the 

 moft ingenious men, ftimulated by a generous ardour for the 

 enlargement of knowledge, led the learned and curious Micheli 

 into this miflake ; and a want of opportunity for obfervation, 

 made it not mended by others.
