Polypodium virginianum, commonly known as rock polypody, rock cap fern, or common polypody, is a small evergreen species of fern native to the Eastern United States and Canada. It generally grows on rocks and occasionally on tree roots in nature.
Description
Polypodium virginianum is a small rhizomatous fern with narrow leaves 8–40 centimetres (3.1–15.7 in) long and 3–6 centimetres (1.2–2.4 in) wide borne on smooth, scaleless petioles 3–15 centimetres (1.2–5.9 in). Leaves are evergreen, oblong and pinnatifid with acuminate tips.
Large, circular sori are prominently featured on the underside of fertile fronds in late summer and autumn. Sporangia are intermixed with long brown glandular hairs.[2]
Taxonomy
Polypodium virginianum has several synonyms including: P. vinlandicum A. Love & D. Love, P. vulgare L. var. americanum Hooker,[3] P. vulgare L. var. virginianum (L.) D. C. Eaton.[4] It is generally treated as distinct, though some have recommended it is equally well treated as a North American variety of the circumboreal Polypodium vulgare.[2]
This species is an allotetraploid of hybrid origin, the parents being Polypodium appalachianum and P. sibiricum.
Distribution and habitat
Polypodium virginianum typically grows on boulders, cliffs, and rocky slopes and does not need well-developed soil. It is common throughout eastern North America; its native distribution ranges from Newfoundland to Yukon south to Georgia, Alabama, and Arkansas.[2]

About Interactions
Most organisms interact with other organisms in some way or another, and how they do so usually defines how they fit into an ecosystem. These intereactions come to us fromGlobal Biotic Interactions (GLoBI), a database and webservice that combines interaction data from numerous sources, including iNaturalist. You can actually contribute to this database by adding the "Eating", "Eaten by", and "Host" observation fields to observations that demonstrate those interactions.

About Names
Most categories of organisms have "common names" in spoken languages. These names are usually recognizable, easy to pronounce, and stable over time, but many organisms have several different names in different places, even in the same language, which can make it difficult to communicate about these organisms without confusion. Scientists address this problem by using a single "scienti...
