Aegilops triuncialis (drawing from the United States Grass Guide,
A.S. Hitchcock , 1950)
Thorny spikelets with a long spine are attached to animals and people, contributing to the spread of the plant.
An annual herbaceous plant 20-45 cm tall, the stems in most cases erect.
The leaves are linear, flat. The leaves, tongue and upper part of the sheaths of the leaf are ciliated.
Ears of 3.5-7 cm long (not counting the spines), with 4-5 (less often with 3 or 6) spikelets, narrow-lanceolate. At the base of the ear there are 2-3 rudimentary spikelets. Spikelet scales are oblong, ovate or obovate, less than 2 times shorter than the adjacent lower floral scales, cartilaginous, with 7-13 wide veins, rough or short-haired, at the apex with 2-3 a few slightly deviated awns from the spike axis. Spikelet scales of the upper spikelet 4.5-6 mm long. The ribs of the axis of the ears are often only with sharp tubercles, without longer spines. Grains do not grow together with flowering scales.
Wind and self-pollinating plant. Autochor. Propagated by seeds. It blooms in May, bears fruit in June. Ploidy 2n = 28 [3] .
