Rye ( Secale cereale ), illustration
The inflorescence is usually a simple spike , which is densely and laterally compressed, and stands individually at the tip of the stalk. The spikelets are double-rowed, with one spikelet on each shoulder of the spikelet axis. The spikelet is sessile and two-flowered. There is a stem-like extension above the florets. The florets are hermaphroditic. There are seldom three hermaphroditic flowers or one or two sterile flowers over the two fertile flowers. The glumes are subulate, keeled and single-nerved. The lemmas are lanceolate, keeled and five-nerved. On the keel there is stiff hair that protrudes like a comb. The lemma has a long, straight, rough awn .
The representatives of the genus occur mainly in the temperate areas of Europe and Asia.
The information on the number of species varies between 3 and 8, depending on whether some plant species are viewed as subspecies or as separate species. Grin lists four types, R. Govaerts nine:
- Secale africanum Stapf (Syn .: Secale strictum subsp. Africanum (Stapf) K. Hammer ): It occurs in the Capensis.
- Secale anatolicum Boiss. (Syn .: Secale strictum subsp. Anatolicum (Boiss.) K. Hammer ): It occurs from southern Greece to Iran.
