Moneses uniflora, the one-flowered wintergreen (British Isles),[2] single delight, wax-flower,[3] shy maiden, star of Bethlehem (Aleutians)[4], St. Olaf's candlestick (Norway), wood nymph, or frog's reading lamp,[5] is a plant of the family of Ericaceae, that is indigenous to moist coniferous forests in temperate regions of the Northern Hemisphere from Spain to Japan and across North America.

The genus Moneses originates from the Greek work moses, which translates to 'solitary,' and hesia, meaning 'delight,' referencing the single flower which blooms on the plant.

[6] The plant is also referred to as wood nymph, referencing a nature goddess figure in Greek mythology that lived in forests and resembled beautiful women.

[6] A perennial herb with a slender rhizome, the leaves are basal or low, oval-elliptic to obovate, from 10 to 30 mm in diameter, with small teeth.

[7] Moneses uniflora has floral features (like poricidal anthers and small apical pores) consistent with flowers that reproduce through buzz pollination.

[7] Some scientific studies have explored the antifungal/viral/biotic properties of single delight flower extracts, and found that aerial parts from Moneses uniflora have inhibited growth against M. tuberculosis and M. avium mycobacteria.
