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