Aquilegia chrysantha var. chaplinei (Standl. ex Payson) Lott | |
Aquilegia chaplinei, also known as Chaplin's columbine,[note 1] is a species of flowering plant in the family Ranunculaceae native to the arid Guadalupe and Sacramento Mountains of West Texas and southeastern New Mexico in the West South Central United States. A perennial plant with an average height of 40 centimetres (16 in), A. chaplinei is characterized as a dwarf version of its close relative Aquilegia chrysantha and is sometimes considered a variant of this species. A. chaplinei's leaves are in a basal arrangement (sprouting from base of the shoot) and give the plant a fern-link appearance when not flowering. Its flowers are pale yellow. It is named for W. R. Chapline, the first person to collect the plant and who collected the holotype from Sitting Bull Falls in New Mexico in 1916.[3]: 74 [4]: 157
Description
[edit]Aquilegia chaplinei is a perennial plant with a height from 20 centimetres (7.9 in) to 50 centimetres (20 in),[5] averaging 40 centimetres (16 in) tall. This is somewhat shorter than the closely related Aquilegia chrysantha, which can reach up to 120 centimetres (47 in) tall.[3]: 74–75 A. chaplinei's type locality at an altitude of 1,650 metres (5,410 ft) suggests that it is better adapted than A. chrysantha to arid environments.[4]: 157 A. chaplinei has a slender stem that is glabrous (smooth) with the exception of the inflorescence.[4]: 156
Possessing leaves in a basal arrangement (sprouting from base of the shoot). Its leaves extend on slender petioles that are 7 centimetres (2.8 in) to 10 centimetres (3.9 in) long.[4]: 156 The leaves themselves range from bi- to barely triternately compound. A. chaplinei has a fern-like appearance when not flowering.[4]: 156 [3]: 74–75 The leaves are semi-evergreen.[2]
It has pale yellow flowers. Its spurs range from 30 millimetres (1.2 in) to 40 millimetres (1.6 in) and can be slender, straight, or slightly spreading.[3]: 74 The short spurs and sepals under 2 centimeters long – between 13 millimetres (0.51 in) and 16 millimetres (0.63 in)[3]: 74 – are the primary distinguishing features that separate A. chaplinei from A. chrysantha.[2] A. chaplinei has yellow sepals.[6]
Taxonomy
[edit]
A. chaplinei is within the Aquilegia (columbine) genus.[1] The plant, including its holotype,[7] was first collected by W. R. Chapline from Sitting Bull Falls in New Mexico on May 25, 1916. It received the binomial Aquilegia chaplinei in 1918 within Edwin Blake Payson's "The North American Species of Aquilegia", published in Contributions from the United States National Herbarium.[4]: 156–157 [6] The holotype is now in the collection of the National Museum of Natural History.[7]
In 1985, Emily J. Lott proposed reclassifying the plant as Aquilegia chrysantha var. chaplinei in the journal Phytologia. Lott's proposal came out of her study of plants in the Chihuahuan Desert, stemming from her 1979 unpublished master's thesis on Aquilegia in the Trans-Pecos region of Texas.[8] The name proposed by Lott was not broadly accepted outside of Texas,[3]: 74 where it is used by the Lady Bird Johnson Wildflower Center of the University of Texas at Austin.[2]
Distribution
[edit]The species is endemic to the Guadalupe Mountains of West Texas and southeastern New Mexico in the West South Central United States.[1] The Guadalupe Mountains are an extremely arid environment, and A. chaplinei is found where the ground is moist such as along streams, canyons, and at the base of rocks.[5][3]: 74 It is also native to the New Mexican Sacramento Mountains.[2]
A. chaplinei is considered a rare flower.[2] The species is of conservation concern.[6]
Cultivation
[edit]As of 2003[update], both seeds and plants were sometimes available, particularly from native plant nurseries in the region of A. chaplinei's native range.[3]: 74
