Crinum brachynema, called Karna phul is an ornamental restricted to Gujarat and Maharashtra States in western India. Due to its narrow range of distribution and extreme rarity, it has been listed as Critically Endangered.
It was first imported into the UK from India by Messrs Loddiges of Hackney, who sent the bulbs on to William Herbert at Spofforth (North Yorkshire). Herbert subsequently described C. brachynema as a new species, in 1842.
Restricted to the North Western Ghats of western India, where it occurs in three areas: in the Dharmapur forest range of the Bulsar District in Gujarat State at about 700 m above sea level; at Kate’s Point, Mahabaleshwar; and on the Kas Plateau, Satara District of Maharashtra State, at 1,250–1,300 m above sea level. It is usually found on lateritic plateaus along the margins of stunted, semi-evergreen forest, and more rarely on hill slopes. It has been found growing in association with Adelocaryum coelestinum, A. malabaricum, Crinum woodrowii, Curculigo orchioides, Curcuma caulina, C. neilgherrensis, Euphorbia nana, Habenaria brachyphylla, H. grandifloriformis, Ledebouria species, Pimpinella heyneana, Pinda concanensis, Pteris quadriaurita and Strobilanthes reticulata.
A bulbous herb, 30–60 cm high, with an ovoid bulb 5–8 cm across. The leaves develop after the flowers, and are erect, then recurved, folded, bright to dark green, linear-oblong, moderately firm, with a smooth margin and an obtuse (blunt) apex. The scape (leafless flower stalk) is stout, almost circular in cross-section and 30–60 cm long. The fragrant flowers are borne in an umbel (of 5–20 individual flowers). The spathe (sheathing bract) bears two valves, is lanceolate and 3–5 cm long. The bracts are awl-shaped or thread-like. The pedicel (individual flower stalk) is as long as the ovary. The perianth (petals and sepals) is funnel-shaped and the tube is slightly curved, greenish, and 3–5 cm long. It has six lobes, which are pure white, oblanceolate to oblong, obtuse, cuspidate (abruptly tipped with a sharp, rigid point) and about 5 x 2 cm long, many times longer than the stamens. The six stamens are attached to the throat of the perianth tube. The filaments are short (about 1 cm long), and are attached to the tube. The pollen grains are mono-aperturate (have a single opening), ovoid, 50 x 55 µm. The exine (outer wall) is micro-verrucate (warty) with bulbous excrescences (outgrowths). The ovary is about 1 cm long and slender. The style is shorter than the stamens and the stigma is shortly three-lobed. The fruit is sub-globose
