Glyceria maxima (Hartm.)
 Holmb.
 (syn.
 "G. aquatica" (L.) Wahlenb.; "G. spectabilis" Mert.
 & W.D.J. Koch; "Molinia maxima" Hartm.; "Poa aquatica" L.), commonly known as Great Manna Grass, Reed Mannagrass, and Reed Sweet-grass, is a species of rhizomatous perennial grasses in the mannagrass genus native to Europe and Western Siberia and growing in wet areas such as riverbanks and ponds.
 It is highly competitive and invasive and is often considered to be a noxious weed outside its native range.
There are many species in the plant genus Cynoglossum ( ).
 They are coarse-appearing, small-flowered plants of the family Boraginaceae.
 "Cynoglossum officinale", the common hound's-tongue, is a native of Asia, Africa, and Europe.
 It has been introduced into North America, and it is considered to be a troublesome weed because its burs stick to the wool of sheep and to other animals.
 Ingestion of this plant can also lead to photosensitivity in grazing animals.
Clarkia unguiculata is a species of wildflower known by the common name elegant clarkia or mountain garland.
 This plant is endemic to California, where it is found in many woodland habitats. Specifically it is common on the forest floor of many oak woodlands, along with typical understory wildflowers that include "Calochortus luteus", "Cynoglossum grande" and "Delphinium variegatum".
 "C. unguiculata" presents a spindly, hairless, waxy stem not exceeding a meter in height and bears occasional narrow leaves.
 The showy flowers have hairy, fused sepals forming a cup beneath the corolla, and four petals each one to 2.5 centimeters long.
 The paddle-like petals are a shade of pink to reddish to purple and are slender and diamond-shaped or triangular.
 There are eight long stamens, the outer four of which have large red anthers.
 The stigma protrudes from the flower and can be quite large.
 Flowers of the genus "Clarkia" are primarily pollinated by specialist bees found in their native habitat "Clarkias independently developed self-pollination in 12 lineages."
Molinia (moor grass) is a genus of two species of flowering plants in the grass family, native to damp moorland in Eurasia and northern Africa.
 They are both herbaceous perennial grasses.
