description: <i>Cryptocarya barrabeae</i> Munzinger &amp; McPherson, sp. nov. (Fig 3; 4) TYPUS. — <b>New Caledonia</b>. Province Sud, Col d’Amieu, fl., 11.II.2005, <i>Barrabé, Pillon, D., I. &amp; C. Létocart 280</i> (holo-, P [P01963123!]; iso-, MO [MO-2849659!], NOU [NOU004589!], P [P01963124!]). DIAGNOSIS. — Among New Caledonian species of <i>Cryptocarya</i>, the new species most closely resembles <i>C. pluricostata</i> in having relatively large leaves (blades mostly&gt; 7.5 cm long and petioles&gt; 10 mm long) with typically more than five pairs of lateral veins and a dense, suberect indument; however, in <i>C. barrabeae</i>, sp. nov., the leaf blade is elliptical (vs ovate in <i>C. pluricostata</i>), the longer petioles at midpoint are&gt; 2.5 mm in diameter (vs 2 mm), the indument of the inflorescence axes is longer (0.5-1 mm) and more-or-less straight (vs short &lt;0.5 mm and contorted) and that of the abaxial leaf surface is persistent (vs mostly worn away at leaf maturity), and the hypanthial cavity is densely pubescent (vs glabrous). PHENOLOGY. — Buds/flowers in January, February; green fruit in June and November. VERNACULAR NAME. — Citronelle (French) fide Papineau (in <i>MacKee 37451</i>), but this name is given to several species of the genus with this odour (Sarlin 1954). LOCAL USE. — Used as timber. ETYMOLOGY. — The plant is dedicated to Laure Barrabé, whose excellent flowering collection alerted us to the existence of this new species, and whose studies of the genera <i>Psychotria</i> and <i>Thiollierea</i> (Rubiaceae) have increased our understanding of New Caledonia’s flora (Barrabé <i>et al</i>. 2011a, b; 2012; 2014; Barrabé 2014). HABITAT. — The tree is restricted to the “forêts denses humides de basse et moyenne altitudes sur roches volcano-sédimentaires” sensu Jaffré <i>et al</i>. (2012); it has been encountered between 390 and 760 m. DISTRIBUTION. — The plant is known from Col d’Amieu (in the South) to Mandjélia (in the North), on the eastern part of the main Island “Grande Terre” (Fig. 4). CONSERVATION STATUS. — The plant appears to be quite common in dense humid forest; and is probably under-collected. It occurs in Aoupinié and Panié protected areas in North Province, and Parc des Grandes Fougères in the South Province. The calculated EOO is 2321 km 2 and the AOO is 117 km 2, but there is no identified threat to the species. We assign <i>Cryptocarya barrabeae</i>, sp. nov., a preliminary status of Least Concern (LC).

DESCRIPTION Tree 4-20 m; 25-50 cm in diameter. Bark brown, somewhat rough, not aromatic.Twigs subterete, densely pubescent with long, erect, reddish brown, straight to somewhat curved, persistent hairs; lenticels not evident in the leafy portions; terminal buds densely erect-pubescent. Leaves alternate; blades elliptical, 4-13.5 × 2-7(-9) cm; base broadly acute (in the smaller leaves) to obtuse (in the larger), often briefly attenuate; apex rounded to truncate or briefly acuminate to an acute or narrowly obtuse tip; margin not or only slightly revolute; texture subcoriaceous; adaxial surface glossy, scrobiculate, glabrous except on the midrib and larger veins, abaxial surface dull, sometimes glaucous, scrobiculate (sometimes only shallowly so), pubescent with long (<i>c.</i> 0.5 mm), erect, reddish brown, essentially straight hairs, the hairs persistent on mature leaves; lateral veins 5-7(-8) on each side, regularly spaced, slightly sunken on the adaxial surface, prominently raised abaxially, lower venation typically evident on both surfaces; petioles (7-)11-22 × 1.6-3.5 mm, densely pubescent, flat adaxially. Inflorescences axillary, 2-3(-4) cm long, sometimes appearing terminal, paniculate, densely pubescent; reduced leaves of the terminal inflorescences 3-6 mm long, caducous, densely pubescent; bracts and bracteoles 1-2 mm long, caducous, densely pubescent; pedicels essentially absent, the flowers sessile or very nearly sessile above the most distal bracteoles. Flowers yellowgreen, 6-7 mm long, <i>c.</i> 3 mm in diameter distally, externally densely pubescent, the tube 3-4 mm long, <i>c.</i> 2 mm in diameter, the tepals 2.5-3 mm long, 1-1.5(-2) mm wide, erect at anthesis, equal (in height), narrowly ovate, densely pubescent adaxially; stamens 9, all 2-celled, pubescent, <i>c.</i> 1.5 mm long, slightly shorter than the tepals and hidden behind them; the filaments <i>c.</i> 0.5 mm long, the anther cells <i>c.</i> 1.0 mm long, the connectives prolonged beyond the anther cells; paired glands at the bases of the inner three stamens globose, <i>c.</i> 0.5 mm in diameter; staminodia ovoid, <i>c.</i> 1 mm long; pistil glabrous, <i>c.</i> 4 mm long, the style not exerted; receptacle cylindric, densely pubescent within. Fruits pubescent and longitudinally ridged when immature; mature fruits not known. NOTE Cited as [<i>Cryptocarya</i> sp. “ aff. pluricostata ” (<i>Barrabé 280</i>)] in Munzinger (2013).
