The salt clouds ( Puccinellia ) are a genus of plants within the sweet grass family (Poaceae). The genus is distributed worldwide, but the focus is on the temperate areas of the northern hemisphere .

Vegetative characteristics

The salt plumes are mostly perennial , more rarely one or two year old herbaceous plants . These grasses grow in tufts, the perennial species as eyrie , the renewal shoots usually grow high within the leaf sheaths (intravaginally). The leaf sheaths are open to the base, on the back they are rounded, their surface is usually smooth and bare. The ligule is a membranous border. The leaf blades are flat, folded or rarely rolled up. In the bud position they are folded, rarely rolled.

Generative characteristics

The paniculate or rarely assembled racemose inflorescences contain spikelets. The spikelets contain three to ten flowers and are laterally compressed. All flowers are hermaphroditic. The unequal glumes are lanceolate to ovate with a blunt to pointed upper end and on the back they are rounded. They are bald, membranous with a thinner edge. The lower glume is single-nerved (rarely up to three-nerved), the upper three-nerved. Both are shorter than the lemmas . These are five-nerved, lanceolate to egg-shaped, also membranous with a thinner edge and rounded on the back. The palea are two-veined and of the same length as the lemma. They are notched at the top, the sides are broadly folded. They are hairy on the keels. There are three stamens ; their anthers protrude from the tip of the flower. The ovary is bare and has two short styles with densely feathery scars .

At maturity, the spikelet axis disintegrates between the flowers, the glumes remain. The caryopsis falls out together with the cover and palea. It has an elongated to elliptical shape. The embryo is about a quarter as long as the fruit. The navel is punctiform to elliptical.

Systematics

The genus Puccinellia was first published by Filippo Parlatore . The generic name Puccinellia honors the Italian doctor and botanist Benedetto Luigi Puccinelli (1808-1850).

The genus Puccinellia belongs to the tribe Poeae in the subfamily Pooideae within the family Poaceae .
