Aquilegia moorcroftiana

Aquilegia moorcroftiana is a species of flowering plant in the genus Aquilegia (columbines) in the family Ranunculaceae 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.

The species is named after William Moorcroft, a British mountaineer and explorer of Ladakh and Tibet.[2]: 104 

Description

edit

Aquilegia moorcraftiana generally ranges from between 2 decimetres (7.9 in) and 4 decimetres (16 in) tall with stems usually featuring two or more flowers.[3]: 90  The flower petal blades, which range from between 10 millimetres (0.39 in) and 13 millimetres (0.51 in) long, are blue with rounded tips. Sometimes they have light yellow margins. The blue-purple nectar spurs are thin and extend for between 12 millimetres (0.47 in) and 17 millimetres (0.67 in).[2]: 102 

Taxonomy

Sixty-seven species of Aquilegia were identified in Philip A. Munz's 1946 Aquilegia: The Cultivated and Wild Columbines, which is considered the principal authority on the genus. Later authorities on Aquilegia show little consensus regarding the number of species, subspecies, and varieties.[2]: 51  Aquilegia moorcroftiana was first described by British botanist John Forbes Royle in 1834 in his book Illustrations of the Botany and Other Branches of the Natural History of the Himalayan Mountains and of the Flora of Cashmere.[1] The type locality is at Ladakh in Kashmir.[3]: 89 

As of 2003, the Flora Iranica made reference to three species of Aquilegia that were described as "Species nova ex affinitate remota Aquilegia moorcroftiana" but unknown in the United States. The botanist Robert Nold noted that political circumstances between Iran and the U.S. would mean that the species would "probably remain nothing but names for years too come". Nold mentioned them within the species A. moorcroftiana, saying that he hoped "that A. moorcroftiana is more polymorphic than anyone suspects".[2]: 103 

A dwarf variety known as A. moorcroftiana var. afghanica is found in the western portion of the range. This variety, sometimes referred to as ''A. afghanica, is more pubescent. While the flowers are generally colored identically to the standard variety, they are morphologically distinct. The type locality is in the Kurram Valley of Pakistan.[2]: 103 

Etymology

edit

The species is named after William Moorcroft, a British mountaineer and explorer of Ladakh and Tibet.[2]: 104 

Distribution

edit

The native range of A. moorcroftiana is found in central Asia, spanning Afghanistan, Tajikistan, Pakistan, Kashmir, Nepal, and Tibet.[1] A. moorcroftiana grows at the highest elevation of any species of columbine, with examples frequently found in both open terrain and among shrubs at over 4,000 metres (13,000 ft) of elevation.[2]: 102 

A. moorcroftiana is thought to be the most common species of Aquilegia in the southwestern portion of the Karakoram mountains.[4]

Cultivation

edit

In 1852, A. moorcraftiana was introduced as a cultivated species in English gardens. Munz reported in 1946 that it remained "very sparingly listed" in nurseries, with Munz noting that at least one cultivated plant advertised as Aquilegia glandulosa appearing more similar to A. moorcroftiana.[3]: 90 

Cultivation of the plant in the United States was noted by Nold in 2003, who observed occasional transfer of seeds through rock garden seed exchanges and the return of collectors bringing back seeds from the Himalayas.[2]: 103
