Ischaemum is a genus in the tribe Andropogoneae, belonging to the grass family, widespread in tropical and semitropical regions in many countries. [4] [5] [6] [7] [8] [9] Many species are known commonly as murainagrass.

Contents

In 2022, Shahid Nawaz (an agrostologist, The Blatter Herbarium (BLAT)) described an unusual species in the genus characterised by its dioecious breeding system, it was named as Ischaemum dioecum Landge & R.D. Shinde. [7] This species is endemic to a couple of locations in Western Ghats of Raigad district, Maharashtra, India. [7] The male and female plants are sexually separate individuals and occupy similar ecological niches. [7] This is the only dioecious species in the tribe Andropogoneae. [7]

They are widely distributed, with the centers of diversity for the group occurring in tropical regions, particularly the Americas. Very few species extend to temperate regions, with only 16 species in the United States, mostly in the southern states from California to Florida, only two species in Canada, and only one species in Europe. They tend to be associated with wet soils, many growing in shallow water. This is also reported from the southern part of India and the regions of Western Ghats hot spots.

The species are variable in morphology, but in general, the plants are less than 0.5 m in height. They bear inflorescences shaped like umbels, with several plumes lined with rows of spikelets. The genus is characterized by the series of sterile florets above the lowest fertile ones, spikes usually 4–10 in numbers, approximated or in a slightly separated series of 10–20 spikes, rarely an indefinite numbers of terminal spikes. In India, 11 species are known to occur in which only two are endemic viz. Chloris wightiana Nees ex Steud. and Chloris bournei Rangachariar & Tadulingam.

Ischaemum rugosum, also known as saramollagrass, is a flowering plant belonging to the grass family Poaceae in the genus Ischaemum, and is native to tropical and temperate regions of Asia, growing in marshes and other wet habitats. It is a vigorous annual, and is an invasive species in South America and Madagascar. It reaches heights of up to 1 m and is primarily recognized by the ridged surface of its sessile spikelet’s lower glume. Despite its historic importance as fodder in Asia, the grass has become a major weed in mid-latitude rice paddies throughout Asia and South America.

<i>Rottboellia cochinchinensis</i> Species of grass

Rottboellia cochinchinensis is a species of grass known by the common names Itchgrass,Raoul grass, corngrass, Kokoma grass, Guinea-fowl grass, jointed grass, Shamwa grass and Kelly grass. It is a tall, tufted annual grass whose stems (culms) grow up to 3 metres in height with leaf-blades of up to 45 centimetres in length. The species flowers at the apex of culms in the form of spike-like racemes composed of paired spikelets. The common name Itchgrass comes from the bristly (hispid) leaf-sheath which can be irritating to the skin.
