LASTREA RIGIDA. 47 
year passed, and its new fronds were dwarfed, 
dark, and ill-natured-looking ; moreover they were 
evidently rotting away. I looked for the reason, 
and found a large Fern, planted above rigida, 
dropping some of its surplus wet upon it. I 
moved it to a clearer place, and at last I gave 
satisfaction. I housed it in winter, and planted 
it in a clear sunny spot in summer, protecting 
the young fronds as I do those of Polystichum 
lonchitis, and it has rewarded me beyond my 
expectation. It has now a crown of healthy 
fronds covered with fructification, and it has 
thrown out two young plants at its side : when 
these are well established I shall try the parent 
Fern out of doors all the year, covering it with 
litter during hard frosts.
