. A history of British ferns. Ferns. 128 MARSH FERN. and very fragile ; the texture thin and almost membranaceous; the colour pale green. The fertile frond differs in being much more taU and robust, and in having the margins of the pinnules convolute, and the pinnules themselves are thus rendered nar- rower, and apparently more distant. The lateral veins of the pinnules are alter- nate ; they are forked almost immedi- ately on leaving the midvein, and each branch proceeds to the margin of the pin- nule (as shown at page 123), bearing a nearly circular cluster of capsules about midway between the midvein and mar- gin : at the back of each cluster, in an early stage of the frond, may be seen a small, flat, whitish, reniform involucre, as represented in the figure in the mar- gin ; this soon withers, is pushed aside by the swelling capsules, and is lost: the clusters of capsules become confluent, and are always concealed by the semi- bleached semi-membranous margin of the €ultmt This fern grows freely, provided the soil be sufficiently peaty and the supply of moisture abundant: if this can be done in no other way, it may always be accomplished by digging out the ordinary soil, and making a cemented bottom upon which to spread the peat: saturate this thoroughly with water; too much cannot be given, as the rhizomes will thrive equally well when constantly submerged. For gi-eenhouse cultivation, use the largest obtainable seed-pan without any aperture for the escape of water: sift peat-earth through a coarse sieve, and mix it with charcoal broken small, in the proportion of seven parts peat to one of charcoal: arrange the rhizomes among this compost and saturate with water : no protection against sun is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Newman, Edward, 1801-1876.
