Text Appearing Before Image:
g fronds of our speciesare merely a little more incised or cut-toothed on the edges, andeven in these fronds, only the upper portion, on which the fruitappears, has this character, while the lower portion, which bearsno sori, is like the barren ones. Sometimes all the fronds, bar-ren as well as fertile, are incised, which condition was formerlysupposed to denote a distinct species, named A. Schzvciiiitzii,but this distinction has now been abandoned. In an average-sized pinna there is but a single row of sori oneach side of the midrib, but in tlie stronger ones there is gener-ally a double row, and at the season of maturity the whole backis covered with the sporangia. Explanation of the Plate.— i. A plant rather below the medium size. — 2. Pinna froma male frond, showing the disposition of the veins. — 3. Pinna from the fertile portionof a frond, just previous to the bursting of the sporangia through the membrane of theindusium, and e.xhibiting its more deeply cut margin. Vol, n.
