  • Description

    Species Description - Small tree or shrub, 1-6(-10) m tall, 2-8 cm in diam. Young twigs and petioles totally covered with stellate scales 0.1-0.4 mm in diam. Petioles 2-4 mm long, 13 mm in diam. Lamina mostly narrowly obovate, to narrowly elliptic, 10-20(-30) cm long, 3.5-8(-10) cm wide, leaf index 2.5-4, chartaceous, slightly bullate and greyish green above, brown below, glabrous above, sparsely covered with stellate scales 0.1-0.3 mm in diam. below, base acute, apex acuminate (acumen 5-25 mm long), primary vein impressed above, secondary veins curved to straight, 12-17 on either side of primary vein, raised above, angles with primary vein 6080°, loop-forming at obtuse to right angles, loops distinct, smallest distance between loops and margin 3-5 mm, tertiary veins raised above. Inflorescences among leaves or on older branchlets, leaf-opposed or supra-axillary, occasionally near the base of a lateral shoot, exceptionally terminal, a single rhipidium or composed of 2-3 rhipidia and/or sometimes becoming (densely) ramified and glomerulate at last; rhipidia 1-2-flowered, to 7 flowers in succession. Indument: peduncles, pedicels, inner side of sepals, and both sides of petals densely to totally covered with stellate hairs 0.1-0.2 mm in diam., outer side of sepals densely to totally covered with stellate scales 0.1-0.2 mm in diam., inner, basal 1/2 of petals glabrous. Peduncle 1-3 mm long, 2-3 mm in diam. Sympodial rachis to 8 mm long. Pedicels 2-7 mm long, 2-5 mm in diam. Upper bract at the base to 1/4 of base of pedicel, deltate to very shallowly triangular, 2-4 mm long. Flower buds depressed ovoid-triangular. Flowers greenish white to white in vivo. Sepals connate for 10-30%, very broadly to depressed ovate-triangular, 10-20 mm long, 10-20 mm wide, acute to obtuse. Petals subequal, ovate-triangular to elliptic, 16-40 mm long, 14-30 mm wide, acute to obtuse, inner base of inner petals callose, distinctly grooved. Stamens 1.5-4 mm long, cream, apex of connective discoid, 0.2-0.7 x 0.7-1.1 mm, densely covered with simple hairs to 0.1 mm long. Carpels 2-6 mm long, ovary densely covered with stellate scales, stigma glabrous to papillate. Fruit green to yellow in vivo, globose to ellipsoid, 2-7 cm long, 2-5.5 cm in diam., basal collar composed of 12-20 connate, sterile carpels, 10-14 mm in diam., not or slightly protruding below the fruit, fertile carpels 50-100, obpyramidal to trulloid, 15-20 mm long, 6-15 mm in diam., free to fused for 10%, areoles very shallowly pyramidal, 1-7 mm high, obtuse, apiculate (apicule 1-6 mm long), surface wrinkled to crested, densely covered with stellate scales ca. 0.1 mm in diam. Seeds obovoid to obtrulloid, 8-13 mm long, 5-9 mm in diam., acute to obtuse, cream to very pale brown, shiny.

  • Discussion

    Duguetia yeshidan is characterized by narrowly obovate, shortly petiolate leaves, which often have a distinctive greyish green color when dried. In fruit it is distinguished by its strongly-wrinkled carpels. D. yeshidan resembles most D. calycina, from which it differs most clearly by the fruit. See further notes under D. calycina.
