Trees grow as native plants across the integral state of Texas . The greatest denseness and multifariousness of tree diagram types in Texas , however , is found in East and Central Texas , including the West Gulf Coastal Plain ( Region 2 ) and the Oaks and Prairies ( Region 3 ) . identify a Texas tree successfully involves using a detailed verbal description of its leaves in improver to general information about the develop habit of the tree diagram and its emplacement .

Arrangement

The agreement of tree leaves on the twig or arm is one piece of data that point to designation . Leaves may alternate on either side of the stem at different superlative . On the other bridge player , leave may be opposite one another at the same level on the twig . voluted leaves are arranged with several leaves — three or four — at the same degree . Crape Myrtle , a Texas favourite tree or bush , has diametric leaf close to the trunk and may have whorled leaves at the terminal of a shoot .

Shape

The name of leaf condition are often descriptive . egg-shaped leaves are elliptical and longer than they are wide , and they are shaped equally around the gist . Ovate leave of absence are bollock shaped with the base broad than the end or apex of the leaf . The Cedar Elm that grows in North Texas has elliptical leaf . A heart - shaped leaf , called cordate , has a across-the-board base with a pass where the leaf sequester to the stem and is triangular . Hastate leaves are sharply notch on both side and wider at the base . The notch may be deep enough to seem as freestanding leafs without nigh inspection . lancelike farewell are narrow , spear shaped and triangular .

Edge

The five vulgar leaf edge types are lobed , serrate , dentate , wiggly and entire . lobate leaves have bland border with declamatory divisions or indents that go almost to the heart of the folio . Texas native oaks have lob leaves . The depth of the indention come apart lob leaf from wiggly leaves , which also have undulating edges but shallower indentations . Dentate and serrate foliage edges have the appearing of modest tooth ; serrated leaf border , however , are sawlike and direct upwardly , whereas dentate leaves ' teeth are more even in size and run to point outwards . Entire leaves have a smooth edge .

Veins

Leaf nervure may be parallel , pinnate or palmate . Parallel veins are equidistant and straight . Pinnates have a meat vein with smaller side vena grow from the pith toward the edge and slant upward . Palmates are shaped like the palm of a hand ; larger nervure are on each section with little veins radiate from each large mineral vein . Texas Sabal Palm is an example of a palmate - flip Sir Herbert Beerbohm Tree .

Color

Even on a unmarried tree , the color of leave exchange with the seasons . Therefore , color is less effective for tree leafage identification than leaf arrangement , shape and edges . Noting the general color of a tree ’s leaves in summer , however , such as light greenish , shiny immature , dark green or grey - green , may help oneself in cause a correct designation of a tree in Texas .
