Phippsia concinna

HABIT Perennial; caespitose. Culms 2–15(–25) cm long. Ligule an eciliate membrane. Leaf-blades 1–3 cm long; 0.5–2 mm wide. Leaf-blade apex obtuse.

INFLORESCENCE Inflorescence a panicle; exserted.

Panicle open; pyramidal; 1.5–4 cm long; 1–3 cm wide. Primary panicle branches appressed, or ascending; bearing spikelets almost to the base.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 1.3–1.6 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes deciduous; similar; shorter than spikelet. Lower glume lanceolate; 0.2–0.5 mm long; 0.3–0.6 length of upper glume; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 0.3–0.6 mm long; 0.2–0.3 length of adjacent fertile lemma; hyaline; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma ovate; 1.3–1.6 mm long; hyaline; keeled; 3 -veined. Lemma lateral veins obscure; less than two thirds length of lemma. Lemma surface hispidulous; hairy below. Lemma apex acute. Palea 2 -veined. Palea keels ciliolate.

FLOWER Anthers 1.

FRUIT Caryopsis with adherent pericarp; ovoid; exposed between gaping lemma and palea at maturity. Hilum elliptic.

DISTRIBUTION Europe: northern and eastern. Asia-temperate: Siberia and Soviet far east.
