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