Dr. Smith's Characters of Hookeria. 275 



ferent from the English one, all other parts of their fructification, 

 fts well as habit, agreeing so well as they do. 



I have great pleasure in dedicating this genus to my young 

 friend Mr. William Jackson Hooker of Norwich, F.L.S., a mos°t 

 assiduous and intelligent botanist, already well known by his in- 

 teresting discovery of Buxbaumia aphylla, as well as by his sci- 

 entific drawings of Fuci for Mr. Turner's work ; and likely to be 

 far more distinguished by his illustrations of the difficult genus 

 Jungermannia, to which he has given peculiar attention. The 

 reticulated habit of this his favourite genus accords with what is 

 most remarkable in my Hookeria. 



To the 2 species already mentioned I am enabled by Mr. Mcn- 

 zies's bounty to add 6 more, as well as 2 from the Linnrean her- 

 barium, of all which I beg leave to offer the following generic 

 and specific characters.
