NOTES ON HYPOPTERYGIUM. 
By Canon H. W. Lert, M.A., M.R.1.A. 
(Pirate 463.) 
Tur genus Hypopterygium differs from other Musci in having 
the branch-leaves arranged in three rows, after the manner of many 
leaves are Po nad with rows of longitudinal cells, and the tea aves 
of the front rows are more or less 2 midiate. All the species are 
natives of warm countries, poe! ew Ze saland, Australia, Tas- 
mania, Brazil, Jamaica, Tibet, id Japan. My attention was 
drawn to these most curious mosses by the discovery in 1887 of a 
colony of a species growing i cold fern- tne at Easton Lodge, 
Monkstown, Co. Dublin che! meio eis of Greenwood Pim, Esq. “y 
F.L.S. I received several plants from Mr. Pim it in 1 1899, which are 
growing and looking quite healthy under glass in a cold pit devoted 
to the cultivation of He epatice in my garden; and it is still flourishing 
and occasionally fruiting in Mr. Pim’s house, where of course it is an 
pct Museum and Kew, and Messrs. Mitten nnd Binstead, and it 
not been identified with any known species. I therefore submit 
the ean description :—
