T TJXBRIDGE EILMY FERN. 
a )HIS and the following are the smallest British ferns, and are remarkable for their moss-like 
! appearance. 
It seems to have no particular time for springing up, as new and withered fronds may always 
he found mixed together in every mass. 
The roots are wiry and adhere strongly to the surface of damp rocks. The rhizomes are 
creeping and much matted together. The stem is about half as long as the frond, and the whole 
rarely attains the length of three inches. The frond consists of veins very much branched and 
covered with a filmy wing, which is serrate. The seed is contained in cup-like involucres, supported 
on short stalks, between the stem and the branches, which split open at the top when the seed is 
ripe to allow the capsules to escape. 
On damp rocks, generally near streams, in all mountainous districts.

This fern is difficult to cultivate, but I have found the following plan to succeed best:—Bill the 
bottom of a large earthenware saucer (pierced in the bottom) with pieces of broken brick or sand¬ 
stone ; over this place a layer of Spagnum, and then a thin layer of soil composed of peat and sand 
in equal proportions, in which the fern must be planted. It must be kept covered with a plate of 
glass and well supplied with water.

WILSOX’S EILMY XERX. 
HIS species is rather larger than H. Tunbridgense, but very much resembles it, so that they 
^ are often mistaken for one another; but a close inspection shows them to be distinct. 
The same description applies to it in every particular, except that the wings are rarely more 
than three times divided; that they are drooping while those of H. Tunbridgense are erect; and the 
involucre is pointed and entire at the top, while that of H. Tunbridgense is rounded and serrated. 
The same as H. Tunbridgense, but it is rather rarer.
