Chrysopogon festucoides (Presl) Veldk. is reported from Kerala in South India. A detailed description, illustration and photographs of the taxon are provided for easy identification.
Two new species of Poaceae, Tripogon karnatakensis and T. munnarensis from South India are described and illustrated. T. karnatakensis closely resembles T. filiformis, but differs in having 15–28 cm long leaden green spikes with 2-keeled lower glumes. T. munnarensis closely resembles T. narayanae, but differs in having 10–16 mm long spikelets with 10–16 florets.

ABSTRACT. Tripogon bimucronatus Thoiba & Sunil, a new species of grass from the Nelliyampathy Hills, Palakkad District of Kerala, South India is described and illustrated. It is morphologically similar to Tripogon vellarianus Pradeep but differs by having adaxially scabrid, linear-acuminate leaves; ligules a fringe of hairs to 2.5 mm long; spikelets with 6–8 closely packed florets; lower glume asymmetrical; upper glume awned; lemma awn scabrid; palea elliptic-lanceolate, apex bimucronate and notched at the centre.
The present investigations were carried out in Melghat Tiger Reserve, regarding the morphology of grasses as an aid to their correct identification, their distribution and indigenous uses in the area. The study area is globally known by its large Reserve Forest and it has rich floral diversity. From the study area 126 species of grasses belonging to 11 tribes were collected. The largest tribe was Paniceae followed by Andropogoneae having 98 and 28 species, respectively. The grasses play an important role in economy of the people of the area. Mainly, grasses are used as fodder in the area; some grasses are used for thatching and for medicinal purpose. There is deterioration of the habitat of grasses due to overgrazing. In situ conservation is recommended for future research.
A new species Dimeria kalliadense, collected from the lateritic plateau of Northern Kerala, India is described and illustrated. This new species is similar to Dimeria keralae in having intertwining racemes, oblique tip of the pedicel, long callus and callus hairs, upper glumes with round and echinate dorsal surface, but differs in having two sub-equal racemes, long pedicel, larger and distantly arranged spikelets, aristate upper glumes, acuminate lower glume, very long and hairy column of awns, lower lemma with dorsal keel and larger vinaceous anthers.
A floristic account is provided for the grass family as part of the vascular plant flora of the contiguous protected areas of Organ Pipe Cactus National Monument, Cabeza Prieta National Wildlife Refuge, and the Tinajas Altas Region in southwestern Arizona. This is the second largest family in the flora area after Asteraceae. A total of 97 taxa in 46 genera of grasses are included in this publication, which includes ones established and reproducing in the modern flora (86 taxa in 43 genera), some occurring at the margins of the flora area or no long known from the area, and ice age fossils. At least 28 taxa are known by fossils recovered from packrat middens, five of which have not been found in the modern flora: little barley (Hordeum pusillum), cliff muhly (Muhlenbergia polycaulis), Paspalum sp., mutton bluegrass (Poa fendleriana), and bulb panic grass (Zuloagaea bulbosa). Non-native grasses are represented by 27 species, or 28% of the modern grass flora. No other large family in t...
Abstract Tripogon idukkianus, a new species of grass from the Ramakkalmedu hill slopes of Idukki district of Kerala, South India is described and illustrated. The new species differs from T. anantaswamianus in having 5–13 mm long, acuminate glabrous leaves, 6–14 flowered spikelets with secund florets, 4-lobed scabrid lemmas with 3 awns each, and 2-keeled ciliate paleas with an obtuse or acute apex with two subapical setae.
