Ferns of Hot Springs National Park and Vicinity

Hot Springs National Park is located in central Arkansas in the eastern part of the Ouachita Mountains. Due to its mountainous character there is a wide range in the natural topography within the area of the park itself and in the surrounding region. One may find rocky bluffs or dry hillsides either open or shaded by a growth of pine, oak, and hickory. The soil is mostly acid, derived from the disintegration of shaley sandstone. There are also isolated outcrops of limestone especially toward the north. In the deeper valleys are accumulations of humus and richer soil, often damp and boggy from springs at the base of the rocky cliffs. Such a varied range of natural conditions would naturally support a wide variety of ferns. The following list represents the collection made by the writer in Hot Springs National Park and the immediate vicinity. POLYPODIUM POLYPODIOIDES (L.) HIitchc. Gray Polypody. Common on trees with rough porous bark and on moist mossy rocks, in moderate shade. ADIANTUM PEDATUM L. Maiden-hair Fern. Occasional at base of shady wooded slopes in rich, moist, well drained soil. Rocky bluffs near the Ouachita River and other smaller streams.

Jersey Meeting of the British Empire Naturalists' Association

THE decision of the council of the British Empire Naturalists' Association to hold a summer holiday meeting at Jersey in the latter half of June is an interesting tribute to the natural history interests of the Channel Islands, where so many Continental and North African plants reach the northern limit of their distribution, and certain reptiles and birds unknown in England may be studied. In its flora, Jersey holds most interest to the British naturalist for the very mild winters permitting up to forty species to flower in late December, thus producing a Continental rather than British flora. The most interesting species on the island not found in the rest of the British Isles are the Jersey bugloss; the Jersey toadflax, one of the rarest of European flowers blooming at the end of May; the Jersey star thistle; and the loose-flowered orchid. The region of St. Ouens Bay is considered the richest botanically, for there are few woods on the island, though such rare flowers elsewhere in Britain as the wild daffodil flourish on the cliffs, maiden hair fern in certain rocks, wild wallflower on the walls of Mont Orgueil Castle, yellow horn poppy, golden samphire, sea-lavender and sea kale on the coast. Scirpus americanus, found at St. Ouen's Ponds, is a very rare rush of the Jersey flora, while the Jersey fern (Gymnogramme leptophylla, Des.), a North African species, is equally interesting.

Timber, and Some of its Diseases 1

IV. BEFORE proceeding further it will be of advantage to describe another tree-killing fungus, which has long been well known to mycologists as one of the commonest of our toadstools growing from rotten stumps, and decaying wood-work such as old water-pipes, bridges, &c. This is Agaricus melleus (Fig. 15), a tawny yellow toadstool with a ring round its stem, and its gills running down on the stem and bearing white spores, and which springs in tufts from the base of dead and dying trees during September and October. It is very common in this country, and I have often found it on beeches and other trees in Surrey, but it has been regarded as simply springing from the dead rotten wood, &c., at the base of the tree. As a matter of fact, however, this toadstool is traced to a series of dark shining strings, looking almost like the purple-black leaf-stalks of the maidenhair fern, and these strings branch and meander in the wood of the tree, and in the soil, and may attain even great lengths—several feet, for instance. The interest of all this is enhanced when we know that until the last few years these long black cords were supposed to be a peculiar form of fungus, and were known as Rhisomorpha. They are, however, the subterranean vegetative parts (mycelium) of the Agaric we are concerned with, and they can be traced without break of continuity from the base of the toadstool into the soil and tree (Fig. 16). I have several times followed these dark mycelial cords into the timber of old beeches and spruce-fir stumps, but they are also to be found in oaks, plums, various Conifers, and probably may occur in most of our timber-trees if opportunity offers.

A Chapter in the History of the Coniferæ

II. GINKGO (Linnæus) THE perhaps better known name of this genus is Salisburia (Smith), but the Linnæan name, adapted from the Chinese, has unfortunately priority. The genus contains only one existing species, the gigantic Ginkgo biloba of Northern China and Japan. It is classified with the Taxeæ, is diœcious, and the flabelliform leaves are deciduous, leathery, very variably lobed, and of all sizes up to an extreme of five inches across. The fruit, about an inch in diameter, is drupaceous, on a slender footstalk, composed externally of a fleshy layer, and internally of a hard light-coloured shell, and is somewhat unsymmetrical, owing to the abortion of one of the seeds. The foliage is like that of the maidenhair fern, but the petiole is stout, often three inches long, and distinctly articulated at the base. An important characteristic in recognising the fossil leaf, besides the petiole, is that however irregularly they may be lobed, they are almost invariably primarily bilobed.
