Th ro u g h o u t th e progress o f th is publication, I cannot promise m yself a more g ra te fu l ta sk , th a n
th a t o f d edic a ting a small b u t m o st e legant species of ray favorite genus to Dawson T u rn e r, Esq.,
as a memoria l o f th e g re a t an d undiminished kindness vvhich I have fo r many yeai-s received from
him. T o his friendly advice and in stru c tio n s th e p re s en t work is indebted for wha tev e r m e rits i t
mav possess. J . Turneri has h ith e rto been found alone in th e neighborhood o f B antry, and is one
o f th e many in te re s tin g additions th a t have be en made to th e Cryptogamic Flo ra o f th e B ritish
Isles, by Miss Hutchins. I t is n o t a little rem a rk ab le th a t this is th e second species of
Ju n g e rm an n ia , discovered by this lady, th a t is distinguished from all th e r e s t o f its affinities (which,
in th e p re sent instance, I need h ardly say, are J . hicuspidata, J . byssacea, Sfc.) in h aving th e leaves
den ta te ii in a very conspicuous and strik in g ly b e au tifu l m a n n e r : th e former p lan t o f this
d e sc ription is J . Hutchinsice, repre sented on th e first pla te o f this Monograph; and I have, on this
account, th e g re a te r pleasure in affixing to th e species th e names o f two botanists, who have alike
ren d e red themselves celebraled by th e ir knowledge and discoveries.
Bcrtides th e d enta te leaves, th e re is ano th e r p e culia rity possessed by th e p re s en t p lan t, th a t I
have n o t observed in any o th e r o f th e g e n u s : th is is in th e la rg e cellules with which th e whole of
th e foliage and surculi appe a r to be studded, in th e same m an n e r as th e leaves o f Dicranum
pulv inalum and a few o th e r mosses; for, th o u g h these ai'c d is tantly placed, they ai'e, nevertheless,
iUTaiiged in lo n g itu d in a l and pai-allel lines.
