The Grass Diversity of Vagamon Hills in Kerala

2014

Grasses contribute tremendously to the earth’s green mantle of vegetation. They are one of the most widely distributed groups of angiosperms with gross morphological complexity. Among flowering plants Gramineae, with their 10,000 species and 620 genera is the fourth largest family of the flowering plants. They owe their importance in the plant kingdom not so much to their multiplicity of species as to their ability to flourish and spread quickly in great areas of low rainfall. Many are cultivated as cereal crops, as ornamentals and as plants of medicinal and industrial importance. Grasslands form an important vegetation type in the high ranges of Western Ghats in the states of Karnataka, Kerala and Tamil Nadu, mostly between 1000-2200 m above msl. The species diversity is extremely high in grassland-forest margins that are very frequent in south Indian forest vegetation especially along Nilgiri and Anamalai - High Ranges. The grasslands of South India, especially Vagamon hills are r...

MORPHO-TAXONOMIC STUDY OF SOME GRASS SPECIES OF THE CAMPUS OF SANT GADGE BABA AMRAVATI UNIVERSITY, AMRAVATI

From the very beginning of inception of human beings on the earth man has relied on plants to fulfill his basic needs for his survival. Plants provide food, shelter and health. It is estimated that about ten million species of plants inhabit the planet earth of which, however only 1.7 million species are known to science. It is therefore the need of the hour to explore the floristic wealth of the earth so as to know what we have. The plant diversity however is under serious threat due to various anthropogenic factors and many plant species are disappearing. Many species are becoming extinct even before their discovery. This scenario necessitates the urgent need of conservation of this diversity. To formulate various strategies for this purpose, the first important step is to explore and inventories the flora. Keeping this perspective in view the present studies were conducted in the university campus to explore and inventorize the grass species in the

International Journal for Research in Applied Science and Engineering Technology, 2021

The present study was aimed to determining Diversity of grass species of Sendhwa Dist. Barwani, Madhya Pradesh, India. Sendhwa is bestowed with unique diversity of ethnic culture and natural resource. The present study is based on diversity of grass species in Satpura region of Sendhwa Dist. Barwani, of Madhya Pradesh, India during the period of 2017-2020. This area is the representative of climax vegetation and rich in grass biodiversity. On the basis of grass utility three species are abundantly found along with 38 genera and 45 species are frequently occurred in Sendhwa dist. Barwani. The data from the primary and secondary sources resulted in the documentation of 45 species belonging to 38 genera. The study area has a rich species diversity of grasses.

An annotated checklist of the Grasses (Poaceae) of Southern Assam

Check List, 2013

We provide a checklist of grass flora along with the details of life form a ~ 6922 km2 area located in the southern part of Assam (Barak valley). This area harbors 98 grass species belonging to 49 genera of the Poaceae. Subfamily Panicoideae (52 species) had the highest number of species followed by Bambusoideae (25 species), Chloridoideae (13 species), Ehrhartoideae (4 species), Centothecoideae (3 species) and Arundinoideae (1 species), while subfamilies like Anomochlooideae, Aristidoideae, Danthonioideae, Pharoideae, Pooideae and Puelioideae were not represented. The region accounts ca. 32% of the diversity of grass flora of the state of Assam.
