Semiaquilegia is a genus of flowering plants of the family Ranunculaceae, native to eastern Asia. The genus was first proposed by the botanist Tomitaro Makino in 1902. Most authorities generally hold that there is only one species in the genus, Semiaquilegia adoxoides , though other species have been proposed as members. The Royal Botanic Gardens, Kew's Plants of the World Online accepts four species of Semiaquilegia.
The genus Semiaquilegia a perennial herb of the Ranunculaceae family. The plants possess tuberous roots. The arrangement of the leaves is basal (protruding from the stem's base) and cauline (attached to aerial stem). [2] Some small leaves will grow on the flower stem during the early summer. [3]
Semiaquilegia plants flower, with flowers that are actinomorphic (possess radial symmetrical). These flowers possess five petaloid sepals and five petals. The petals are in a basally gibbous arrangement. There are 8 to 14 stamens. [2] Characteristic of the genus, inner stamen can resemble flattened staminodes. [4] : 45 The anthers are yellow. [2] While Semiaquilegia flowers can resemble those of Aquilegia , Semiaquilegia flowers lack nectar spurs or possess extremely short spurs. [3]
Fruit appear in groups of three to five follicles that diverge. [3] The seeds of the genus are colored brown to black-brown and heavily wrinkled. [2]
The Japanese botanist Tomitaro Makino proposed the establishment of Semiaquilegia as a genus in 1902. Makino assessed the characteristics of the genus as approximating the appearance of plants in the genus Aquilegia , but with several distinctions. Among the features of Semiaquilegia that Makino identified were the absence of nectar spurs, the presence of fewer than 15 stamens, and possession of inner stamens that look like flattened staminodes. [4] : 45
In 1920, British botanists James Ramsay Drummond and John Hutchinson published a paper, "A Revision of Isopyrum (Ranunculaceae) and Its Nearer Allies", in the Royal Botanic Gardens, Kew's Bulletin of Miscellaneous Information to address problems that had developed within the genus Isopyrum . In order to address the substantial morphological variance that had coexisted within Isopyrum, Drummond and Hutchinson segregated out the genus Paraquilegia and expanded Semiaquilegia to include species formerly identified as Isopyrum. [5] [4] : 46 The American botanist and gardener referred to the 1920 expansion of Semiaquilegia to four species as "rather less fortunate". These new Semiaquilegia have been subsequently removed from the genus, with only S. adoxoides accepted as part of the genus by 2003. [4] : 46–47
The generic name Semiaquilegia is derived from the name for the genus Aquilegia (columbines), to which they are closely related, and literally translates as "half-columbines". [4] : 46
Species are regularly described, synonymized, or reassigned to other genera, so presently only one is considered valid by most authorities: the type species Semiaquilegia adoxoides . [2] [4] : 45–47 There are four species accepted by the Royal Botanic Gardens, Kew's Plants of the World Online: [6]
Semiaquilegia is native to East Asia. [3] If the genus is understood as only encompassing Semiaquilegia adoxoides, its range extends across China, Japan, and Korea. [2]
According to the Alpine Garden Society, Semiaquilegia are well-suited to pot cultivation at alpine houses. The plants require well-drained soil and can be short-lived. Propagation can be achieved by sowing seeds when they are fresh and in the spring. Division can also be used in propagation, if performed carefully. [3]
Aquilegia is a genus of about 130 species of perennial plants that are found in meadows, woodlands, and at higher elevations throughout the Northern Hemisphere, known for the spurred petals of their flowers.
Isopyrum is a genus of flowering plants of the family Ranunculaceae native to Eurasia and North America. Isopyrum plants possess white flowers with five sepals and five petals.
Aquilegia chrysantha, the golden columbine, is a perennial herbaceous flowering plant native to the southwestern United States and northwestern Mexico. The plant, with a height of between 40 centimetres (16 in) and 120 centimetres (47 in), has yellow flowers. A. chrysantha. as with other members of the Aquilegia coerulea species complex, is evolved for pollination by hawkmoth. It favors moist environments in its mountainous range.
Paraquilegia uniflora is a species of perennial flowering plant in the family Ranunculaceae. Its range spans Tajikistan to the mountainous border between Afghanistan and northern Pakistan. It is a cushion plant with flowers that are blue or creamy white.
Aquilegia alpina, often called the alpine columbine or breath of God, is a perennial species of flowering plant in the family Ranunculaceae, native to the western and central Alps. Though rare in its Swiss, Austrian, and Italian range, it is commonly found in the French Maritime Alps. A. alpina is appreciated for its light blue to blue-purple flowers.
Semiaquilegia adoxoides is a species of perennial flowering plant in the Ranunculaceae. Native to Japan, Korea, and China, the plant grows to about 40 cm (16 in) tall and blooms with pale pink flowers. Now often considered the sole member of the genus Semiaquilegia, it bears similarities to members of the genus Aquilegia. S. adoxoides is native to China, Korea, and Japan and has an introduced population on Taiwan.
Urophysa is a genus of perennial flowering plants belonging to the family Ranunculaceae, endemic to China.
Aquilegia gegica is a species of flowering plant in the genus Aquilegia (columbine) in the family Ranunculaceae endemic to the western South Caucasus region in Abkhazia and Georgia. The plant's flower petals are light blue.
Paraquilegia is a genus of flowering plants belonging to the family Ranunculaceae. The genus was segregated out from the genus Isopyrum in 1920 by British botanists James Ramsay Drummond and John Hutchinson. The native range of the genus is temperate central Asia.
Aquilegia moorcroftiana is a species of flowering plant in the genus Aquilegia (columbines) in the family Ranunculaceae. It is native to central Asia, with a range spanning Afghanistan, Tajikistan, Pakistan, Kashmir, Nepal, and Tibet. A. moorcroftiana grows at the highest elevation of any species of columbine, with examples frequently found at over 4,000 metres (13,000 ft) of elevation.
Aquilegia sibirica, the Siberian columbine, is a species of flowering plant in the family Ranunculaceae native to the north-central Asian regions of Siberia, northern Mongolia, Kazakhstan, and Xinjiang. A hardy perennial plant, it prefers temperate environments. The Siberian columbine can be between 1 foot (0.30 m) and 2 feet (0.61 m) tall with flowers that are lilac-blue and white in color.
Aquilegia micrantha, the Mancos columbine or Bluff City columbine, is a perennial species of flowering plant in the family Ranunculaceae. It is native to Utah, Colorado, and Arizona. The species grows to between 30 cm (12 in) and 60 cm (24 in) tall and produces flowers that can be white, cream, blue, or pink.

Aquilegia amurensis is a partially accepted species of flowering plant in the genus Aquilegia (columbines) in the family Ranunculaceae that is native to northeast Asia. Its natural range is in the northern Greater Khingan mountain range and Amur River of China, as well as Siberian Russia, Mongolia, and possibly North Korea. Flowers of this plant have petal blades that are whitish or white-tipped, with blue-violet nectar spurs and sepals. The plant is rarely cultivated.
