Puccinellia

Common salt plume ( Puccinellia distans )

The salt plume ( Puccinellia ) are a genus of plants of the family Gramineae ( Poaceae ). It is named after the Italian botanist Luigi Benedetto Puccinelli ( 1808-1850 ). The genus is distributed worldwide, but the focus is in the temperate regions of the northern hemisphere.

Features

The representatives of the genus are mostly perennial grasses, rare is an annual or biennial plants. They grow in tufts, the perennial species as Horst, renewal shoots usually grow up within the leaf sheaths (intravaginal ). The leaf sheaths are open to the bottom, on the back they are rounded, its surface is usually smooth and bare. The ligule is a membranous hem. Leaf blades are flat, folded or rolled in rare cases. In the vernation they are folded, rarely rolled.

The inflorescence is a panicle or raceme. The spikelets consist of three to ten flowers and are laterally compressed. All flowers are hermaphrodite. The glumes are unequal. Their shape is lanceolate to ovate, obtuse to acute. You are bald, membranous with a thinner edge. On the back are rounded. The lower glume is einnervig (rarely to three annoying ), the top three annoying. Both of which are shorter than the lemmas. These are five annoying, from lanceolate to egg-shaped, also rounded membranous with thinner edge and back. The palea are two annoying and the same length as the lemmas. Above they are notched, the lateral surfaces are wrapped wide. On the keels they are hairy. There are three stamens; their anthers protrude from the floral lace. The ovary is bald and wears two short pen with dense feathery scars.

At maturity, the Ährchenachse decays between the flowers, stop the glumes. The caryopsis coincides with deck and palea. It has an oblong to elliptical outline. The embryo is about one quarter as long as the fruit. The navel is point-like to elliptical.
