The State of Texas, with a variation in altitude of almost ten thousand feet, and a variation in life zones from Boreal to Tropical, embracing swamp, forest, prairie, desert, and mountain areas, is the home of a very large number of plants. While the distribution of plants has been intensively studied in some small localities, no State-wide work has been done. The results of these limited investigations have never been gathered into one publication. This procedure has resulted in the use of several systems of botanical nomenclature and accordingly misunderstandings easily originate. Little or no work has been done on the general distribution of plants. In many lists a plant is said to exist in Texas, which statement gives little aid to one who wishes to find that plant. The growing interest in plant life which has been brought about in very recent years by the sudden coming into prominence of plants which are poisonous to livestock; of plants which are of value for use in roadside beautification; of plants which because of their hardiness and beauty can be utilized in landscaping farmsteads where little attention can be given; and the mat forming quality of their roots make them a prime factor in erosion control, has created a great demand for a list of the native plants of Texas giving both scientific and standard common names together with their occurrence. To provide such a list a project was outlined and the following has been compiled as a tentative answer to the demand. It was decided that the list should include all plants from Ferns to Composites inclusive. The plants given must be known to occur within the limits of the State, the proof of which must be in the form of the abundant occurrence of the plant; an authenticated reference to the collection of the plant within the State, or to herbarium specimens from reliable collectors. In addition any plant that has been introduced and has definitely proved that it not only can maintain itself but increase in its population, is included.
