Elymus texensis

Elymus texensis, commonly called Texas wildrye, [2] is a species of flowering plant in the grass family (Poaceae). It is native to United States, where it is endemic to the Edwards Plateau of Texas. [3] [4] Its natural habitat is on calcareous bluffs in Juniperus woodlands and grassy areas. [3]

Elymus texensis is a recently discovered and poorly known species. It was described to science in 2006. [5] It is currently only documented from three collections, [3] although further surveys will likely reveal more localities. It appears to be most morphologically similar to Elymus pringlei, which is found further south in Mexico. [5]

<i>Chloris</i> (plant) Genus of grasses

Chloris is a widespread genus of monophyletic grasses belonging to the family Poaceae, known generally as windmill grass or finger grass. The genus is found worldwide, but especially in the tropical and subtropical regions, and more often in the Southern Hemisphere. 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.

Piptochaetium, or speargrass, is a genus of plants in the grass family, native to North and South America. Piptochaetium is a bunchgrass genus in the tribe Stipeae.

Puccinellia pumila is a species of grass known by the common names dwarf akaligrass and smooth alkali grass. It is native to North America where it grows along the coastline in the northern latitudes, from Alaska across Arctic northern Canada to Greenland. It occurs on the coast of the Pacific Northwest in the United States and it is known from the Kamchatka Peninsula. The grass is only found on the coast, in wetland habitat, beaches, and areas inundated by the highest tides, in saline sand and mud. This perennial grass grows decumbent or erect to a maximum height near 40 centimeters, often remaining much smaller, especially in harsh habitat. It may root at stem nodes which become buried in wet substrate. The inflorescence is a dense or open array of branches bearing spikelets.

Bothriochloa ischaemum is a species of perennial grass in the family Poaceae, found throughout much of the world. It is commonly known as yellow bluestem. Two varieties are recognized, of which Bothriochloa ischaemum var. ischaemum is native to Europe, Asia, and Africa and naturalized elsewhere, and var. songarica is native to Asia and naturalized elsewhere. Var. songarica is an invasive weed in Texas, where it is known as "King Ranch bluestem"; it has displaced native grasses in large areas of central and south Texas.
