Stipa arabica

الوصف النباتي

الأوراق

Leaves: Sheaths ridged and hairless, rough, with translucent margins; ligule oval and blunt, finely fringed with hairs. Blades very slender and folded lengthwise.

الأزهار

Inflorescence & flowers: Panicle enclosed at its base by the uppermost sheath, with fine, erect branches. Glumes membranous, linear-lanceolate, tapering to long, soft points; the upper glume slightly shorter. Lemma rolled into a cylinder, with short hairs; palea hardened and channelled. Mouterde distinguishes subsp. damascena from typical S. barbata by the lower part of the bent awn: below the bend it is rough and lightly hairy rather than feathery; above the bend it is feathery. His historical description includes awns around 15 cm long.
