description

Ornithogalum nivale is a perennial , herbaceous bulb plant that reaches heights of 1 to 4 centimeters. The onion is egg-shaped and surrounded by a membranous, somewhat thick, blackish shell. The onion scales are fused. The leaves appear in spring. They are blue-green with a white central stripe, runny, narrowly linear, and with 12 × about 2 millimeters significantly longer than the shaft, their edge is always bare.

The very short shaft is underground. The flowers appear just above the ground. The inflorescence is a little-flowered umbrella cluster . The lanceolate, pointed, whitish-skinned bracts tower above the flower stalks. The bracts are about 12 millimeters long. They are lanceolate, very blunt and have an intense green stripe on the back in the middle with a snow-white edge that is almost twice as wide. The stamens are triangular-lanceolate. The fruit stalks are spread out more or less arched. Germination takes place epigeously.

The flowering time is in June.

The number of chromosomes is 2n = 14.

Occurrence

Ornithogalum nivale is an east Mediterranean floral element. This little-known species is only known for certain from the peaks of Boz Dağ (Tmolus) near Izmir . There it grows at altitudes of about 2100 m in open places on the melting snow. The deposits brought here from Crete and the East Aegean Islands belong to Ornithogalum pumilum .
