Natural history. 448 The Canadian Field-Naturalist Vol. 115 vine; the roots are situated two inches below the surface of the soil, and the bulbs of oval figures, are strung together like beads, being attached to each other by a strong ligament. They are of a blackish brown color, and also resemble potatoes in their general character, being dry, farinaceous and nutritive". Gesner's saa-gaa-ban has characteristics of Apios and occupies habitat similar to that in which it was found on Lennox Island, also in Malpeque Bay. Hinds (2000) reports Segabun as a Mi'Kmaq name for Apios and this plant is well-known as a food of eastern North America's early aboriginal peoples who both gathered it from the wild and transplanted it near campsites (Reynolds et al. 1990). It is possi- ble that this accounts for the species' presence on Lennox Island. Apios is common in southwestern Nova Scotia and scattered elsewhere in that province (Zinck 1998). In New Brunswick, it is scattered in southern areas, reaching as far north as Kouchibouguac National Park (Hinds 2000). Its range extends into southern Quebec and Ontario (Scoggan 1979) and the eastern half of the United States to the Gulf of Mexico (Reynolds et al. 1990). Voucher material and photographs of the newly- discovered Prince Edward Island population are on file with Island Nature Trust. A voucher specimen has been sent to the Department of Agriculture Herbarium in Ottawa. Polystichum braunii (Braun's Holly Fern) Polystichum braunii is an easily recognized fern (Figure 4). Its stipe is conspicuously chaffy, covered in light brown to golden scales. The blade is leathery at both ends, twice pinnate and chaffy beneath and on the rachis. Each pinnule has spiny edges and a sharp lobe at its base, characteristic of the holly ferns. Sori are arranged in two ranks along the midrib and spores are present from June to September (Zinck 1998). In Canada, P. braunii is found from Newfoundland west to sou
