Balfour's Touch Me Not

Impatiens balfourii Hook. fil.

Comments

I have seen populations of this species growing alongside Impatiens bicolor Royle, near Bhagnotar, Abbottabad-Nathia Gall road and may be hybridising with it in nature. Pl. 17, Fig. 3, in Blatter (l.c.) is not that of Impatiens balfourii.

Impatiens balfourii

Impatiens balfourii is a species of the genus Impatiens known by the common names Balfour's touch-me-not, Kashmir balsam,[1] and poor man's orchid. It belongs to the family Balsaminaceae.

Etymology

The Latin name Impatiens means "impatient" or "intolerant" and refers to the explosive dehiscence of the fruits, which burst at the slightest touch as a means of scattering the seeds. The Latin species epithet balfourii honors the Scottish botanist Isaac Bayley Balfour (1853-1922).[2]

Description

This is an annual herb growing 15–120 centimetres (5.9–47.2 in) in height. Its stem is glabrous, reddish, lined and very branched. It has alternately arranged, oval to lance-shaped, toothed, stalked leaves up to 4 centimetres (1.6 in) long. The inflorescence is a raceme generally bearing 4 to 8 flowers. Each flower is about 2 centimetres (0.79 in) long, with one of its white sepals forming a long, thin spur, and two of its yellow-dotted lavender or pink petals extending from the mouth.

Reproduction

The flowers are hermaphrodite, or perfect, and are pollinated by insects, or, in the Americas, by hummingbirds. The flowering period extends from July through September. The fruits are glabrous capsules about 20 millimetres (0.79 in) long and the seeds are dispersed when the fruits burst, launching them up to 6 metres (20 ft) away.

Distribution

It is native to the Himalayas, particularly Kashmir and surrounding areas, where it grows in mountains of 5,000 to 6,000 feet.[3] It was brought back to England and many other European countries as a garden plant, and then it became popular in the San Francisco Bay Area and other parts of the United States.[3] It can now be found growing wild as a garden escapee in Europe, on the US Pacific Coast, and in Wisconsin,[4] where it is a restricted species because of its invasiveness.[5]

Habitat

In the wild the plant occurs along the banks of rivers, on roadsides, and in wastelands. It thrives in cool and moist areas, at an altitude of 100–600 metres (330–1,970 ft) above sea level.
