The apices are tipped with a short bristle. Leaf venation palmate. The contact angle (θ) of water on leaves measured at the gas, solid and liquid interface is an index of surface wettability. Wineberry, Rubus phoenicolasius Flowers. Leaf Surface – Glabrous • The surface is smooth, not hairy. Leaf lower surface green, glabrate or pubescent or with tufts in vein axils, stellate or tomentose. scrub oak (Quercus inopina) Habitat: sandhill and dry pinelands.

The complete, perfect, actinomorphic flowers are arranged in few flowered cymes. 3. I. macrophyllum, with stems and abaxial leaf surface glabrous to puberulent and peduncle with a bract near the middle). Synonyms. The leaf surface is covered with a dense tomentose covering of gray/white stellate hairs. Abaxial leaf surface green or pale and puberulent; simple, tuberculate and smooth-walled trichomes restricted to the midrib and major veins H. arborescens. Leaf blade elliptic, oblong, or ovate, apex acuminate, young branchlets and abaxial surface of leaf blade densely gray-brown tomentose or yellowish brown tomentose. long and in the black group. Place the leaf/stem under the stereo microscope. 12b. Abaxial leaf surface gray-green and hirsutulous and slightly scabrous, 13a. Flowers: inconspicuous. Leaf upper surface green, glabrate or pubescent, stellate or tomentose. Leaves white tomentose beneath, per Vascular Flora of the Carolinas. Leaves are termed as “super-hydrophilic” if θ < 40°, “highly wettable” if θ < 90°, and “wettable” if θ < 110°. Maximum likelihood character mapping of ‘densely tomentose’ trait in the bryoniifolia clade. 2. Observations . (B) The abaxial leaf surfaces of V. (A) Pie charts representing the ML support percentage at ancestral nodes for taxa lacking densely-packed trichomes (white) and those with densely-packed trichomes resulting in a tomentose abaxial leaf surface (black). Wineberry, Rubus phoenicolasius Lateral leaflets sessile or petiolules to 2mm. Leaf Surface • Glabrous • Pubescent • Villous • Tomentose • Scabrous • Glaucous • Rugose • Glandular •There are 8 common leaf surfaces. Leaf Surface – Pubescent • Short, soft hairs cover the surface. Aristolochia durior Hill; Aristolochia macrophylla Lam. Lower leaf surface velutinous, pilose, or tomentose, appearing gray, per Weakley's Flora (2012). Leaf wettability, indicating the affinity for water on leaf surfaces, is a common phenomenon for plants in a wide variety of habitats. Under the stereo microscope, students will be able to see the fine hairs on the surface of the leaf if the leaf/stem has non-glandular, hair-like trichomes on its surface. Buds, young branchlets, and abaxial surface of leaf blade densely gray-brown tomentose; 2-year-old branchlets gray-brown, slightly pubescent, rather The calyx has 5 fused green sepals. 2. The upper leaf surface is bluish to ashy green, and the lower is silvery and tomentose. Family. Tomentose definition is - covered with densely matted woolly hairs. Acorn: ½ – 5/8 in. Plant leaf or stem; Procedure . The leaf surface may be smooth (Figure 13), or wrinkled/rugose (Figure 14), or covered with hairs (pubescent/tomentose, Figure 15) or wax (glaucous, Figure 16). Stipules present, 25–38 mm long, caducous, blade-like, circumferential. Abaxial leaf surface white or gray, hirsutulous to tomentose on veins and inter-venial areas.
