Veronica is the largest genus in the flowering plant family Plantaginaceae, with about 500 species; it was formerly classified in the family Scrophulariaceae.
 Common names include speedwell, bird's eye, and gypsyweed.
Veronica wormskjoldii is a species of flowering plant in the plantain family known by the common name American alpine speedwell.
 It is native to much of northern and western North America, including the western United States and northern Canada, from where it grows in moist alpine habitat, such as mountain forest understory.
 It has a wide subarctic distribution from Alaska to Greenland.
 This is a rhizomatous perennial herb producing a decumbent to erect, mostly unbranched stem up to 25 to 40 centimeters tall and coated in long hairs.
 The oppositely arranged leaves are 2 to 4 centimeters long and lack petioles.
 The inflorescence is a hairy, glandular raceme of flowers at the tip of the stem.
 Each flower has hairy, lance-shaped sepals and a blue corolla up to a centimeter wide.
 The fruit is a capsule around half a centimeter long which contains tiny flattened seeds.
Stewartia (sometimes spelled Stuartia) is a genus of 8-20 species of flowering plants in the family Theaceae, related to "Camellia".
 Most of the species are native to eastern Asia in China, Japan, Korea, Laos, Myanmar, Thailand, and Vietnam, with two ("S. malacodendron, S. ovata") in southeast North America, from Virginia and Kentucky south to Florida and Louisiana.
The Antirrhineae are one of the 12 tribes of the Plantaginaceae family.
 It contains the toadflax relatives, such as snapdragons.
 They are probably most closely related to the turtlehead tribe (Cheloneae) and/or a large and badly resolved core group of their family including plants as diverse as water-starworts ("Callitriche"), foxgloves ("Digitalis"), and speedwell ("Veronica").
 The Antirrhineae include about 30 genera with roughly 320 species, of which 150 are in genus "Linaria".
 The type genus is "Antirrhinum" .
