The leaf surface is covered with a dense tomentose covering of gray/white stellate hairs. scrub oak (Quercus inopina) I. macrophyllum, with stems and abaxial leaf surface glabrous to puberulent and peduncle with a bract near the middle). Synonyms. Increase magnification while focusing and record observations. Habitat: sandhill and dry pinelands. Abaxial leaf surface white or gray, hirsutulous to tomentose on veins and inter-venial areas. The upper leaf surface is bluish to ashy green, and the lower is silvery and tomentose. Leaf blade elliptic, oblong, or ovate, apex acuminate, young branchlets and abaxial surface of leaf blade densely gray-brown tomentose or yellowish brown tomentose. 13a. Leaf venation palmate. long and in the black group. Family. Wineberry, Rubus phoenicolasius The complete, perfect, actinomorphic flowers are arranged in few flowered cymes. The contact angle (θ) of water on leaves measured at the gas, solid and liquid interface is an index of surface wettability. Petioles 5–12 cm long, glabrous or pubescent. How to use tomentose in a sentence. Tomentose definition is - covered with densely matted woolly hairs. Lower leaf surface velutinous, pilose, or tomentose, appearing gray, per Weakley's Flora (2012). Abaxial leaf surface green or pale and puberulent; simple, tuberculate and smooth-walled trichomes restricted to the midrib and major veins H. arborescens. The apices are tipped with a short bristle. The calyx has 5 fused green sepals. (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. Stipules present, 25–38 mm long, caducous, blade-like, circumferential. Aristolochiaceae. Leaf wettability, indicating the affinity for water on leaf surfaces, is a common phenomenon for plants in a wide variety of habitats. 2. Maximum likelihood character mapping of ‘densely tomentose’ trait in the bryoniifolia clade. Flowers. Abaxial leaf surface gray-green and hirsutulous and slightly scabrous, Leaves white tomentose beneath, per Vascular Flora of the Carolinas. Acorn: ½ – 5/8 in. Buds, young branchlets, and abaxial surface of leaf blade densely gray-brown tomentose; 2-year-old branchlets gray-brown, slightly pubescent, rather Plant leaf or stem; Procedure . 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. Observations . Leaves are termed as “super-hydrophilic” if θ < 40°, “highly wettable” if θ < 90°, and “wettable” if θ < 110°. Leaf upper surface green, glabrate or pubescent, stellate or tomentose. Place the leaf/stem under the stereo microscope. Leaf Surface – Glabrous • The surface is smooth, not hairy. Leaf Surface – Pubescent • Short, soft hairs cover the surface. Leaf lower surface green, glabrate or pubescent or with tufts in vein axils, stellate or tomentose. stems and abaxial leaf surface tomentose and the peduncle without a bract (vs. 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). 12b. 2. Flowers: inconspicuous. Leaf Surface • Glabrous • Pubescent • Villous • Tomentose • Scabrous • Glaucous • Rugose • Glandular •There are 8 common leaf surfaces. (B) The abaxial leaf surfaces of V. 3.
