. Our ferns in their haunts; a guide to all the native species. Ferns. CHEILANTHES AND MAIDENHAIR. T first glance the maidenhair fern seems to have very little in common with the various species of Cheilan- tlies, but the way in which they all fruit brings them very close together in the opinion of botanists. Both genera belong to the tribe of which the bracken is a prominent member and, like the species in that genus, bear their sori close to the margins of the pinnules. But here the likeness ends, for there are many patterns after which marginal sori may be arranged. In the bracken the fruit

Both genera belong to the tribe of which the bracken is a prominent member and, like the species in that genus, bear their sori close to the margins of the pinnules. But here the likeness ends, for there are many patterns after which marginal sori may be arranged. In the bracken the fruit is in long lines and covered with linear indusia; in the maidenhair it is under a re- flexed tooth of the pinnule; while in Cheilanthes the edges of the pinnules simply curl over the fruit, and scarcely form an indusium at Cheilanthes Vestita, This interesting little species is rather southern in its distribution, beginning to be rare north of Maryland. It once grew in what is now the northern part of New York City and this is generally supposed to be the fern's northern limit, but a station still further north has been known to a few botanists since 1892 when the plant was discovered near New Haven, Connecticut. This is its northeastern limit, so far as 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 Clute, Willard Nelson, b. 1869.
