We’re trialling a new ‘app switcher’ feature to help our users move between our science apps. For now we’ve just listed some of our more popular apps, but soon we hope to show more and roll it out across all our science websites.
Let us know what you think via the link at the bottom of the app switcher.
Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume linear, or lanceolate; 1 length of upper glume; membranous; without keels. Lower glume apex attenuate. Upper glume linear, or lanceolate; 25-40 mm long; membranous; without keels. Upper glume apex attenuate.
Fertile lemma elliptic; subterete; 14-16 mm long; coriaceous; without keel. Lemma surface pubescent; hairy below; hairy in lines. Lemma margins convolute; covering most of palea. Lemma apex surmounted by a ring of hairs; awned; 1 -awned. Principal lemma awn bigeniculate; 160-300 mm long overall; with twisted column; limb glabrous, or puberulous. Column of lemma awn 50-60 mm long; plumose; with 1-2 mm long hairs. Palea 2 -veined; without keels.
Anthers 3; anther tip penicillate. Stigmas 2. Ovary glabrous.
Caryopsis with adherent pericarp. Hilum linear.
