Liatris cylindracea (known as barrelhead blazing star,[1] cylindric or cylindrical blazing star,[2][3] Ontario blazing star,[4][5][2] or dwarf blazing star[5]) is a plant species in the family Asteraceae. It is native to eastern North America, where its populations are concentrated in the Midwestern United States.[6] It is found in habitats such as prairies, limestone and sandstone outcroppings, bluffs, barrens, glades, woodlands and dunes.
The cylindrical blazing star grows from rounded or sometimes elongated corms, which produce hairless stems 20–60 cm (8–24 in) tall. At the top of the stem is a single flower head or a loose to dense cluster (raceme, spike, or panicle) of 2 to 28 flower heads. Each flower head has 10–35 florets, and is stemless or has a stem 2–10 mm (3⁄32–13⁄32 in) long that orients the head upwards. The flowers bloom in mid to late summer, starting at the top of the cluster.
The basal and cauline leaves usually have three nerves, though sometimes up to five. They are long and thin, ranging from 8 to 25 cm (3+1⁄4 to 9+3⁄4 in) long and 2 to 6 mm (3⁄32 to 1⁄4 in) wide. The leaves are mostly hairless or may have some hairs on the margins. Some plants in Kentucky and Missouri are hairy; this may indicate hybridization with Liatris hirsuta. The largest leaves are a little above the bottom of the stem; above that, the leaves become gradually smaller.
The seed are produced in fruits (cypselae) that are 5–7 mm (3⁄16–9⁄32 in) long with feathery pappi.[7]
Its roots can reach depths of 15 ft (4.6 m).[8]

Liatris cylindracea, ( en inglés : Barrelhead gayfeather, Cylindrical blazing star, o Ontario blazing star),[1] es una especie botánica en la familia Asteraceae y del género Liatris.
Es nativa de noreste y el centro de Norteamérica, donde se le encuentra en hábitat tales como praderas, derrudios de piedra caliza y de piedra arenisca, entre peñascos, y en los claros de los arbolados y las dunas. También se encuentra a lo largo de los bordes de la carretera y en el bosque mixto pino-roble con suelos arenosos, comunidades norteñas arboladas en las laderas de los montes. Florece a mediados de al verano tardío con las cabezas de flor púrpuras.
Crece de bulbos redondeados o a veces alargados, vástagos sin pelo 20 a 60 centímetros de alto. Las flores están en cabezuelas densas con 10 a 35 floretes, y las cabezuelas carecen de vástagos o tienen vástagos de 2 a 10 milímetros de largo que orienten las cabezas hacia arriba. Las cabezuelas producidas quizá simples o en flojo al racimo denso de 2 a 28. Se arreglan en denso punto-como o raceme-como colecciones. Las hojas basales y del tallo tienen tres nervios (algunas pueden tener cinco), que son largos y finos, extendiéndose a partir del 8 a 25 centímetros de largo y 2 a 6 milímetros de ancho. El follaje es sobre todo sin pelo o puede tener algunos pelos en los márgenes (algunas plantas en Kentucky y Misuri son peludas y pueden indicar la hibridación con Liatris hirsuta); las hojas se reducen gradualmente de tamaño mientras que ascienden cerca del extremo del tallo. La semilla se produce en las frutas de los cypselae que tienen 5 a 7 milímetros de largo con mechones plumosos.[2]
Liatris cylindracea fue descrita por André Michaux y publicado en Flora Boreali-Americana 2: 93. 1803.[3]
