Rhynchospora colorata, also known as starrush whitetop, white star sedge and white-topped sedge, is a perennial sedge with white bracts, giving it the appearance of white petals with long, green points. It is native to southeastern North America, from Virginia west to New Mexico in the United States, and south into the Caribbean islands.
Rhynchospora is a genus of about 400 species of sedges with a cosmopolitan distribution. The genus includes both annual and perennial species, mostly with erect 3-sided stems and 3-ranked leaves. The achenes bear a beak-like tubercule and are sometimes subtended by bristles. Many of the species are similar in vegetative appearance, and mature fruits are needed to make a positive identification.
Persicaria pensylvanica is a species of flowering plant in the buckwheat family, Polygonaceae. It is native to parts of North America, where it is widespread in Canada and the United States. It has also been noted as an introduced species in parts of Europe and South America. Common names include Pennsylvania smartweed and pinkweed.

It has also been introduced to parts of France, likely during the First World War.
Rhynchospora californica is a species of sedge known by the common names California beaked-rush and California beaksedge. It is endemic to California where it is mainly distributed in the northwestern corner of the state south to the San Francisco Bay Area. It bears long, thin stems topped with dense inflorescences of dark brown flowers enfolding grainlike fruits that have white-fuzzy tubercles. It is a plant of marshes and bogs.
Rhynchospora alba, the white beak-sedge, is a plant in the sedge family, Cyperaceae. It is a tufted herbaceous perennial around 50 cm tall, with white inflorescences that flower in August. The fruit of the sedge is a small achene with a characteristic beak-like cap. It is dispersed by wind or falls by gravity, leading to individuals existing in tight clumps. The species favours wet, acidic and nutrient poor soils, thriving in Sphagnum-dominated bogs, but also peaty grasslands. As such it is often used as a positive indicator for bog and mire ecosystem health.
Lactuca biennis is a North American species of wild lettuce known by the common names tall blue lettuce and blue wood lettuce. It is widespread across much of the United States and Canada from Alaska and Yukon south as far as California, New Mexico, and Georgia.
Fritillaria purdyi, known by the common name Purdy's fritillary, is a rare species of flowering plant in the lily family.
Pyrrocoma racemosa is a species of flowering plant in the aster family known by the common name clustered goldenweed. It is native to the western United States, where it grows in many types of habitat. It is quite variable in morphology, and there are several varieties which are sometimes hard to tell apart. In general, it is a perennial herb usually producing two or more mostly erect stems reaching maximum heights between 15 and 90 centimeters. The stems are reddish or brownish in color, leafy or not, and hairless to quite woolly. The longest leaves are located in tufts around the base of the stems. They are lance-shaped to oval, smooth-edged, wavy, or deeply spine-toothed, and may exceed 30 centimeters in length. Basal leaves are borne on woolly petioles. Leaves located higher on the stem lack petioles and may clasp the stem at their bases. The inflorescence is a cluster of several flower heads lined with phyllaries which may be over a centimeter long and are hairy to hairless in texture. Each head contains many yellow disc florets and a fringe of several yellow ray florets. The fruit is an achene which may be over a centimeter long including its pappus.
Stephanomeria pauciflora is a species of flowering plant in the aster family known by the common names brownplume wirelettuce, few-flowered wirelettuce, and prairie skeletonplant. It is native to the southwestern United States and northern Mexico, where it grows in many types of habitat, including many desert areas, woodlands, and plains. It is a perennial herb or bushy subshrub producing one or more sturdy, stiff stems with many spreading branches, taking a rounded but vertical form. The leaves are mostly basal and ephemeral, with smaller, scale-like leaves occurring on the upper stem. Flower heads occur at intervals along the mostly naked stems, especially near the tips. Each has a cylindrical base covered in hairless phyllaries. It contains 3 to 6 florets, each with an elongated tube and a flat pink ligule. The fruit is an achene tipped with a spreading cluster of plumelike pappus bristles. These are usually brownish, but are sometimes white. The specific epithet pauciflora, refers to the Latin term for 'few flowered'.
Pleiacanthus is a monotypic genus of flowering plants in the aster family containing the single species Pleiacanthus spinosus, which is known by the common name thorn skeletonweed, or thorny skeletonweed. It is native to the western United States from Montana and Idaho to southern California and Arizona, where it grows in many types of mostly dry habitat from deserts to mountains. It is a spindly subshrub producing several slender stems up to 40 or 50 centimeters tall from a woody caudex. The stems divide many times into short, rigid branches which narrow to sharp thorn-tips. The plant is mostly hairless except for brownish woolly tufts at the base and below the basal leaves. The leaves are small and linear on the lower stem, and reduced to scale-like growths on the upper branches. Flower heads occur near the ends of the branches. Each has a cylindrical base wrapped in one layer of phyllaries. The head contains 3 to 5 ray florets, each with an elongated tube and a pale to bright pink ligule. The fruit is an achene tipped with a cluster of pappus bristles which are not plumelike as are those of the Stephanomeria species with which this plant was once classified.
Trillium angustipetalum, with the common name is narrowpetal wakerobin, is a species of Trillium, plants which may be included within the Liliaceae or the newer family Melanthiaceae.
Rhynchospora knieskernii is a rare species of sedge known by the common name Knieskern's beaksedge. It is endemic to the state of New Jersey in the United States, where it occurs naturallyin the Pine Barrens. Reports have cited it present in Delaware as well, but these populations appear to have been introduced. It is threatened by the destruction and degradation of its habitat. It is a federally listed threatened species of the United States.
