bs. The species of the genus ‘Plagiochila, Sere so abun- 
E 
dant in tropical countries, are very few in Europe, and a 1, with 
one exception, found land, so that my journey of abaat fo 
hundred miles in order to spend three days on gr to 
ound as clas: 
the cryptogamic botanist as Killarney has amply been rewarded by 
the addition of this distinct plant. The first day I was there I visited 
Cromaglown, but being warned off the mountain at the Hunting 
Tower I had to botanize by the staciaa, the third day being spent 
in the Horses Glen, near Mangerton, but the stormy, wet weather 
prevented me doing much collecting. The second day I et by 
the Tore Waterfall, and, pr to hints given me by my friend 
Mr. Holt, I w ollecting most of the rarities, Saleen 
Radula Holtié ‘na Lejeunea Ho ltit. 
Plagiochila kiilarniensis is easil distinguished from any of the 
other native species by the horizontally inserted truncate, bidentate 
leaves, and igen the forms of P. punctata and P. spinulosa are 
very num

et that I was only able to find very little of the Sone but 
omnia ge pegs may be more fortunate; the place where 
I collected it was on the exposed surface of a si aaapetell stone
