Eucomis montana is a plant species in the family Asparagaceae, subfamily Scilloideae, found in South Africa (KwaZulu-Natal and the Northern Provinces) and Eswatini (Swaziland).[1] When in flower in summer, the plant reaches a height of up to 45 cm (1 ft 6 in), with a dense spike (raceme) of greenish flowers, topped by a "head" of green bracts.
Description
Eucomis montana is a perennial growing from a large ovoid bulb with a diameter of up to 8 cm (3+1⁄4 in). Like other Eucomis species, it has a basal rosette of strap-shaped leaves. These are about 50 cm (20 in) long and 12 cm (4+1⁄2 in) wide, with smooth margins and purple spots or speckles underneath. The inflorescence, produced in late summer, is a dense raceme.[2] The plant reaches an overall height of around 25–45 cm (10 in – 1 ft 6 in).[3] The individual flowers have greenish tepals and stamens with purple filaments, and are borne on short stalks (pedicels) 5–10 mm (1⁄5–2⁄5 in) long. The inflorescence is topped by a head (coma) of green bracts, up to 5 cm (2 in) long.[2]
The homoisoflavanone 5,6-dimethoxy-7-hydroxy-3-(4′-hydroxybenzyl)-4-chromanone can be found in the bulbs of E. montana.[4]
Taxonomy
Eucomis montana was first described by Robert Harold Compton in 1967,[1] after he retired to Eswatini (then Swaziland) where it was first found.[2] The Latin specific epithetmontana refers to mountains or coming from mountains.[5] It is one of a group of larger, tetraploid species with 2n = 4x = 60 chromosomes.[6]
Distribution and habitat
Eucomis montana was initially discovered in Eswatini, where it grew in colonies on damp grassland slopes at elevations of 1,500 m (4,900 ft).[2] It has since also been found in South Africa, in KwaZulu-Natal and the Northern Provinces.[1] It grows at elevations of up to 2,080 m (6,820 ft).[3]
Cultivation
As of 2007[update], it was said to be very rare in cultivation, but should prove to be "at least frost-hardy".[7]
