POLYSTICHUM LONCHITIS. 251 
Fern when Ray published, in 1670, his Catalogus Plan- 
tarum Anglice, nor when his Historia Plantarum issued 
from the press, in 1686, but it bad been discovered by 
Mr. Lloyd between that year and 1696, when Ray 
mentions it in the second edition of his Synopsis Stir- 
pium Britannicarum. He adopted the name of Lon- 
chitis aspera major, or " larger rough Sjdeeuwort with 
indented leaves." He says, " It issues from clefts in the 
rocks on the tops of the mountains of Wales, as at 
Clogwyn - y - Garnedh - y - Grib - Goch - Trygvylchan (D. 
Lhwyd)." 
Mr. W. Reeve observes that it is a very ornamental little 
plant when it can be cultivated successfully. He grew 
it in a cool house, where it was constantly shaded, and 
upon a damp bottom, with great success. He employed 
a compost of sandy loam and peat in equal parts, with 
a liberal admixture of sharp sand. It may be cultivated 
upon the rockery, but great care is necessary, it being 
a very shy plant to establish itself in dry, exposed 
situations. A shady part of the rockery must be 
selected, where it can be kept damp ; but it will not 
bear stagnant moisture. It must be planted firmly in 
the compost above-mentioned as early in the spring as 
possible ; and if a hand or bell-glass can be kept over it 
for a short time all the better, as this will keep the soil 
moist about it for some time without the application of 
much water. Give a little air occasionally. 
It will thrive remarkably well in a greenhouse, and 
Mr. Reeve had it produce fertile fronds abundantly in a 
stove temperature. It is difficult to increase except by
