Question: Which plant grows in East Asia, Aquilegia or Semiarundinaria?
Context: Heteropogon contortus is a tropical, perennial tussock grass with a native distribution encompassing Southern Africa, southern Asia, Northern Australia, Oceania, and southwestern North America.  The species has also become a naturalised weed in tropical and subtropical regions in the Americas and East Asia.  The plant grows to 1.5 m in height and is favoured in most environments by frequent burning.  The plants develop characteristic dark seeds with a single long awn at one end and a sharp spike at the other.  The awn becomes twisted when dry and straightens when moistened, and in combination with the spike is capable of drilling the seed into the soil. Sansevieria ehrenbergii (blue sansevieria, sword sansevieria, oldupai, or East African wild sisal) is a flowering plant which grows in northeastern Africa from Libya south to Tanzania, Oman, and Saudi Arabia.  It occurs notably in proliferation along the Olduvai Gorge in northern Tanzania.  Mature leaves are dark green and usually range between 0.5 and 1.5 m in length and 2.45 and 8.0 cm in width.  The plant grows in tight clusters and in close proximity amongst itself. Mendoncia velloziana is a plant native to Atlantic Coast restingas vegetation which is an ecosystem of Atlantic Forest biome.  In addition, this plant grows either in Cerrado vegetation of Brazil.  This plant grows in following states of Brazil: Bahia, Ceará Minas Gerais Rio de Janeiro, São Paulo, Paraná and Santa Catarina, and it is usually visited by the hummingbirds. Delphinium staphisagria is a species of "Delphinium", or larkspur, of the family Ranunculaceae.  This plant is also known as Lice-Bane or Stavesacre.  It is described botanically as a stoutly-stemmed, hairy biennial with large palmate leaves up to 6 inches (15 cm) across.  The flowers are mauve-blue to blue, short-spurred, and up to 1 inch (2.5 cm) across, occurring in racemes.  The plant grows to a height of 4–5 feet.  It grows throughout the Mediterranean.  The dark-colored, wrinkled seeds of "D. staphisagria" are characteristically quite large (~5x6 mm), and it is likely that the species name, which translates to "wild raisin" (classical Greek: σταφὶς ἀγρία) is based on their appearance.  This name-derivation seems to have been arrived at independently by a modern horticulturalist, David Bassett, who also gives a detailed account of his experiences in growing this species.  All parts of this plant are highly toxic and should not be ingested in any quantity. Aquilegia (common names: granny's bonnet or columbine) is a genus of about 60-70 species of perennial plants that are found in meadows, woodlands, and at higher altitudes throughout the Northern Hemisphere, known for the spurred petals of their flowers. Calamus rotang aka rotang is a plant species native to India, Sri Lanka and Myanmar (Burma).  It one of the scandent rattan palms used for Malacca cane in the making of furniture, baskets, walking-sticks, umbrellas, tables and general wickerwork, and is found in Southwest Asia.  The basal section of the plant grows vertically for 10 metres or so, after which the slender, tough stem of a few centimetres in diameter, grows horizontally for 200 metres or more.  It is extremely flexible and uniform in thickness, and frequently has sheaths and petioles armed with backward-facing spines which enable it to scramble over other plants.  It has pinnate, alternate leaves, 60–80 cm long, armed with two rows of spines on the upper face. Semiarundinaria is a genus of East Asian bamboo in the grass family. Polygonum cespitosum or tufted knotweed is a summer annual weed plant of the family Polygonaceae, native to eastern Asia, from China to Japan and Southeast Asia, and introduced into North America.  The plant grows to 3.5 feet (105 cm) in height with elliptic to lanceolate leaves, usually 20–75 mm (0.4-30.0 inches) long.  It has small pink or red flowers arranged in tight terminal spikes. Chorizanthe watsonii is a species of flowering plant in the buckwheat family known by the common name fivetooth spineflower.  It is native to the western United States from Washington to the Mojave Desert.  It grows in many types of plant communities from desert scrub to woodland and sagebrush.  This small plant grows a woolly erect stem up to about 15 centimeters tall.  The inflorescence is a cluster of flowers surrounded by five hairy greenish bracts tipped with hooked awns.  The flower is about 2 millimeters wide and yellow in color. Argemone albiflora, the white prickly poppy, also known as the bluestem prickly poppy or the Texas prickly poppy, is a small erect plant with a decorative white flower with a yellow latex.  It is deeply rooted with yellow or red stamens.  The plant is known for the sharp prickles on its stem and leaves.  The sepals fall off as the flower of this plant grows bigger.  It grows in the arid regions of the southern Midwest along roadsides and disturbed pieces of land.  Native Americans have long revered this plant for its medicinal and other uses.
