Actinodaphne kontumi de Kok, sp. nov.</p> <p>(Figs 1; 2)</p> <p>Actinodaphne reticulata var. reticulata sensu Nguyén Kim Đào, Flora of Vietnam 20: 420 (Nguyén Kim Đào 2017).</p> <p>Actinodaphne reticulata var. glabra sensu Nguyén Kim Đào, Flora of Vietnam 20: 421 (Nguyén Kim Đào 2017).</p> <p>DIAGNOSIS. —This species differs from its close relative Actinodaphne perlucida C.K. Allen by having leaves that are thinly leathery (rather than thickly leathery in A. perlucida) with the midrib raised on the upper surface (rather than sunken in A. perlucida) and the petiole 6-15 mm long (rather than 10-20 mm long in A. perlucida).</p> <p>TYPE SPECIMEN. — Vietnam. Kon-Tum, Massif du Ngok Pan, 9.XII.1946, Poilane 35755 (holo-, P [P02035722]).</p> <p>DISTRIBUTION. — Vietnam. Kon-Tum and Gia Lai provinces (Fig. 2). This species has also been recorded from the Vietnamese provinces of Ha Giang, Vinh Phuc and Thua Thien-Hue as Actinodaphne reticulata var. reticulata and Actinodaphne reticulata var. glabra (see Nguyén Kim Đào [2017]), but specimens on which these records are based have not been seen by the author.</p> <p>ECOLOGY. — This species is known from upland forest over granite, between 800-2000 m altitude. Flowering in December; fruiting time unknown.</p> <p>CONSERVATION ASSESSMENT. — Endangered (EN B1ab(i,iii), B2ab(ii,iii)). This species is only definitely known from a small number of collections from a few localities in the Kon-Tum and Gia Lai Provinces of Vietnam. An analysis of the Extent of Occurrence (EOO) and Area of Occupancy (AOO) gives an IUCN Conservation Assessment of Endangered. Given that it is only known from three populations and has small area of occupancy as well as the intensive logging and landscape modification that has occurred in the region during the last 50 years, this species must be considered endangered.</p> <p>ADDITIONAL COLLECTIONS SEEN. — Vietnam. Kon-Tum: Massif du Ngok Pan, 9.XII.1946, Poilane 35754 (P [P02035820]); Massif du Ngok Pan, 18.XII.1946, Poilane 35936 (P); Massif du Ngok Pan, alt. 2000 m; 18.XII.1946, Poilane 35943 (P [P02035701]); Dak Gley, 6.XII.1995, Averyanov et al.

Twigs slender to stout 3.4-6 cm thick, angular in cross-section, sparsely hairy when young, glabrescent; hairs yellowish, appressed; terminal leaf bud ovoid, 3-4 mm long, apex acute, velutinous. Leaves subopposite, domatia absent; blade elliptic to lanceolate, 5.5-7.5 × 2.2-3 cm, apex long acuminate, base cuneate, blade leathery, triplinerved, secondary nerves extending to leaf tip, brochidodromous, sometimes with a false side vein, tertiary nerves scalariform; upper surface sparsely hairy on major nerves and at base, midrib and secondary nerves sunken to raised, tertiary nerves indistinct; lower surface reddish brown when dried, sparsely hairy, midrib and secondary nerves raised, tertiary nerves distinct; hairs reddish, appressed; petiole half terete, 11-15 cm long, slender, sparsely hairy.</p> <p>Inflorescence 1-10 cm long, a few flowered panicle, axillary, densely to sparsely hairy; hairs yellowish, appressed; bracts leaf-like; bracteoles elliptic, 2-2.4 mm long, apex acute, sparely hairy, caducous. Flowers immature, with reddish appressed hairs.</p> <p>Fruit unknown.</p> <p>NOTES</p> <p>No evidence that this name was ever validly published could be found and so it is validated here. Although it is generally not a good idea, especially in the Lauraceae, to published new species based on incomplete material (in this case lacking fruits and with only immature flowers), this species is clearly a Cinnamomum based on the immature flowers (number of perianth lobes and stamens) and the orientation (subopposite) and venation (triplinerved) of the leaves. Within the genus it is unique because of the reddish appressed hairs on the lower leaf surface.</p> </div>	https://treatment.plazi.org/id/03FC87DAFFE3FFF8D20BFBEFFBE9FBB2	Public Domain	No known copyright restrictions apply.

Leaves alternate to (sub)opposite, drying dark brown, smelling of etheric oils when crushed, domatia absent; leaf ovate to elliptic, 2.5-8 × 1.3-5.2 cm, apex acute, base slightly cordate to rounded, thickly leathery, trinerved, secondary nerves usually one pair, extending up to ¾ of the length of the blade, sometimes more prominent secondary side nerves present distally, tertiary nerves scalariform; upper surface glabrous, midrib and secondary nerves raised to flattened, tertiary nerves indistinct; lower surface glabrous, midrib and secondary nerves raised to flattened, tertiary nerves indistinct; petiole half-terete, 5-20 mm long, slender, glabrous.</p> <p>Inflorescences 2-12 cm long, few-flowered panicles, terminal and axillary, sparsely hairy; bracts leaf-like or absent; bracteoles linear, c. 2.3 mm long, apex acute, sparsely hairy, caducous. Flowers with perianth tube shallow; perianth lobes elliptic, 2.6-3 × 2.2-2.6 mm, apex acute, sparsely hairy outside and inside; stamens 9, 1.8-2.3 mm long, hairy, anthers 4-celled; style and stigma unknown.</p> <p>Fruits unknown.

Specimens have sometimes been placed in the southern Chinese species Cinnamomum rigidissimum H.T. Chang. It differs from this taxon in the placement of the inflorescences (can be terminal) and in the hairiness (pressed yellowish hairs) of the leaves and twigs (glabrous to sparsely grey-brown hairy in C. rigidissimum).</p> </div>	https://treatment.plazi.org/id/03FC87DAFFEFFFF1D07BFF02FE9FFC8E	Public Domain	No known copyright restrictions apply.
