Dallis Grass is considered an introduced or even an invasive species in North America and in many other places around the globe. Here's the apt and succinct thumbnail sketch from Wikipedia: "Paspalum dilatatum is a species of grass known by the common name dallisgrass, Dallas grass, or sticky heads. It is native to Brazil and Argentina, but it is known throughout the world as an introduced species and at times a common weed. Its rapid growth and spreading rhizomes make it an invasive pest in some areas. It is present in the southern half of North America, southern Europe, much of Africa, Australia, New Zealand, and many tropical and subtropical areas." It is definitely an authentic resident of the Western Hemisphere since it is original to the region of South America that are Brazil and Argentina. The range map at the USDA's Plants Database indicates that it is found across the state of Texas though not all counties report or have reported its presence. Greenbelt Park 428 is administered by the Texas Parks and Wildlife Department.

These characteristics include flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; they are fruiting plants, although more commonly referred...
