S. Coll. 776. R. S. in detail. The sporangia occur associated in large masses, and crowded together, representing, no doubt, the collective output of a compound fertile frond. The pyriform sporangia are shortly stalked and grouped in tufts, on the branches of the fertile rachis (see Fig. 123). The latter shows in section the characteristic &)-shaped vascular bundle of the species, thus placing the identification beyond 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 Scott, Dukinfield Henry, 1854-1934.
