Abstract
While collecting woody plants for the Arnold Arboretum, west of the Mississippi River, in the autumn of 1923, I spent several days in October on Magazine Mountain, in Logan County, Arkansas. This proved to be an extremely interesting locality both for its ligneous and herbaceous plants. Amongst a few of the latter class collected were two ferns, which I did not at once recognize (as familiar species for that part of the country). These turn out to be Dennstaedtia punctilobula (Michx.) Moore and Woodsia scopulina D. C. Eaton, both of which, so far as I know, have not been found before in the state nor in that region. Magazine Mountain is an isolated flat-topped eminence, rising about 2000 feet above the surrounding valleys, and with its summit reaching a height of about 2800 feet above sea level. The formation is Pennsylvanian sandstone and shale. The mountain sides are steep, and the summit is bounded by a rim of precipitous bluffs in most places. On the north side these attain in places a perpendicular height of perhaps 200 feet or more, with remarkable accumulations of talus at their base. The top of the mountain is a level tableland, about seven miles in length and from a quarter to three quarters of a mile wide. Deciduous woods, with a small percentage of yellow pine (Pinus echinata), and with many small prairie openings, characterize the general region. The slopes of the mountain are heavily wooded, especially on the north side, where most of the rarer species occur. Oaks, hickories, sweet and black gum, red and sugar maple, linden, cucumber tree, buckeye, chinquapin and many other trees constitute the forest. The herbaceous growth shows much diversity at different levels, and 39
