Cephalanthera longifolia (Sword Leaved Helleborine)

Cephalanthera longifolia, commonly known as the Sword Leaved Helleborine, is a delicate terrestrial orchid native to the Great Himalayan National Park (GHNP). This orchid is recognized by its elegant sword-like leaves and striking white flowers, making it one of the lesser-known yet captivating plants of the Himalayan understory.

Habitat in the Great Himalayan National Park

This orchid thrives in:

  • Mixed coniferous and broadleaf forests

  • Shady, humus-rich soils

  • Elevations between 1,800 and 3,000 meters

It is frequently spotted along quiet forest trails in the Tirthan and Sainj valleys, especially during the spring and early summer months.

Botanical Description

  • Leaves: Long, narrow, and grass-like—hence the name sword-leaved

  • Height: Typically ranges from 20 to 60 cm

  • Flowers: Creamy-white with a yellowish center, blooming from April to June

  • Stems: Upright and thin, often blending with surrounding foliage

Despite its subtle appearance, its flowers are self-pollinating and also attract small forest insects.
