 nists indeed had detected them in the Lemna 

 or Duck-weed, so abundant on the surface of 

 still waters, and Valisneri alone for a long time 

 engrossed the honour of having; seen them, 

 In our days however they rewarded the re- 

 searches of the indefatigable Ehrhart in Ger- 

 many, and on being sought with equal acute- 

 ness, were found in England. Three species 

 have been delineated in Engl. Bot. t. 926> 

 1095 and 1233, from the discoveries of Mr. 

 Turner and Mr. W. Borrer. The flowers 

 of Mosses, long neglected and afterwards 

 mistaken, were faithfully delineated by Mi- 

 cheli, carefully examined and properly un- 

 derstood by Linnaeus as he rambled over the 

 wilds of Lapland *, and at length fully illus- 

 trated and placed out of all uncertainty by 

 the justly celebrated Hedwig. These parts 

 indeed are still unknown in ferns, or at least 

 no satisfactory explanation of them has 

 readied me, though the seeds and seed- 

 vessels are sufficiently obvious. 



* This hitherto unknown fact will appear in his Tour 

 through that country,- now preparing for the press in 

 English.
