The Riza snowdrop ( Galanthus rizehensis ) is a species of the snowdrop ( Galanthus ) genus in the Amaryllis family (Amaryllidaceae). It is named after its first place of discovery in the hinterland of the Turkish Black Sea city of Rize . The name Riza snowdrop is probably due to a confusion with the Riza lake in Abkhazia , especially since the species is also native there. It was first described by Stern.
features
The Riza snowdrop is a perennial herbaceous plant that reaches heights of 8 to 12 centimeters. This geophyte forms an onion as a persistence organ, which is egg-shaped and measures 1.8 to 3 × 0.6 to 1.5 centimeters. The simple leaves are usually dull green and have a pale central stripe, at flowering time they are usually 6.5 to 13 (4 to 16) × usually 0.4 to 0.8 (0.3 to 1) centimeters in size, later 33.5 × 1.4 centimeters. The spot at the end of the inner bracts is usually U-shaped.
The flowering period extends from January to March, sometimes until April.
The number of chromosomes is 2n = 26.
