Botrychium paradoxum is a species of fern known by the common name peculiar moonwort. It is native to North America, where there are scattered occurrences in Alberta, British Columbia, Saskatchewan, Montana, Oregon, Utah, Washington, and Wyoming.[3]
This plant is unique among the moonworts. While other species generally produce one fertile frond and one sterile, this species produces only the fertile frond. This frond has two segments, both bearing spores.[4] The plant grows up to 15 centimeters tall. As the leaflike sterile frond is absent, the plant likely obtains much of its energy from mycorrhizae instead of photosynthesis.[3]
This fern grows in subalpine climates in snowfields and western red cedar forests.[4][3]
