Cryptocarya adpressa Munzinger & McPherson

sp. nov.

Cryptocarya adpressa Munzinger & McPherson   , sp. nov.

( Figs 1 View FIG ; 2 View FIG )

TYPUS. — New Caledonia. Province Nord, Mandjélia , 860 m, fl., 1.X.2009, 20°23’48’’S, 164°31’55’’E, Munzinger et al. 5832 (holo-, P [ P02433555]!   ; iso-, MO [ MO-2849665]!, MPU [ MPU026702]!, NOU [ NOU051487]!).  

DIAGNOSIS. — The new species resembles several other New Caledonian Cryptocarya   species ( C. leptospermoides   , C. gracilis   , C. chartacea Kosterm.   , C. mackeei Kosterm.   , C. schmidii Kosterm.   ) in having relatively small leaves (up to 7 × 4 cm) with pinnate venation, but can be most easily distinguished from them by its persistent and strongly appressed indument on the inflorescences (vs inflorescences glabrous or rapidly glabrate in C. mackeei   and C. schmidii   ), its short (up to 3.6 cm) inflorescences and unraised lenticels (vs inflorescences 5-10 cm and lenticels prominent in C. chartacea   ), and by its relatively long flowers (2.5-3.5 mm) (vs 2.0- 2.5 mm in C. leptospermoides   and C. gracilis   ).

PHENOLOGY. — Flowers in April, May, October, November. Fruits in March, July, August, September, November, December.

ETYMOLOGY. — The specific epithet refers to the tightly appressed indument, very distinctive within New Caledonian Cryptocarya   species.

H ABITAT. — The tree is restricted to the “forêts denses humides de basse et moyenne altitudes sur roches volcano-sédimentaires” sensu Jaffré et al. (2012), from 500 to 1000 m.

DISTRIBUTION. — This tree is known from the forests of the Mont Koghis region in the south to the Tendé basin in the north-east; it apparently does not occur on ultramafic substrates ( Fig. 2 View FIG ).

CONSERVATION STATUS. — The plant appears to be quite common in dense humid forest. It occurs in the Aoupinié and Panié protected areas in the North Province, as well as in Parc des Grandes Fougères, and Thy in the South Province. The calculated EOO is 3067 km 2 and the AOO is 153 km 2, but there is no special threat identified against this species. We assign Cryptocarya adpressa   , sp. nov., a preliminary status of Least Concern (LC).

Tree 6-25 m. Diameter 15-20 cm. Bark brown, somewhat rough to nearly smooth. Twigs somewhat flattened, densely puberulous at first with minute, tightly appressed, essentially straight hairs, soon glabrescent, wrinkled and shallowly ridged at first, becoming smoother in the lower leaf-bearing region, lenticels not prominent; terminal buds densely appressed puberulent. Leaves alternate, blades elliptic to slightly ovate, 2.6-7.0 × 1.1-4.0 cm; base acute to broadly acute, subcuneate to somewhat attenuate-decurrent into the petiole; apex rounded to shortly acuminate and obtuse; margin not or only slightly thickened, typically flush; texture coriaceous; adaxial surface typically glossy, glabrous except near the base while immature, abaxial surface dull, typically glaucous at least when young, glabrous except near the base and on the midrib while immature; lateral veins (4-)6-9 on each side, uniformly pinnate, flush on both surfaces or slightly raised adaxially, lower venation obscure or very finely reticulate on both surfaces; petioles 4-7 × c. 2 mm, flat adaxially.

Inflorescences axillary or appearing terminal, 1.2-3.6 cm long, paniculate, densely appressed puberulent; peduncle 3-22 mm long, 1 mm wide; bracts up to 5 mm long, bracteoles up to 1 mm long, acute, caducous; pedicels (uppermost bracteoles to hypanthium base) of at least the central flower of each dichasium 0.5-1.0(-2.0) mm long, those of the lateral flowers often shorter. Flowers yellow-green to green, 2.5-3.5 mm long, 2-3 mm in diameter at anthesis, externally appressed puberulent, the tube 1-1.5 mm long, the tepals 1.5-2.3 mm long, erect to slightly spreading at anthesis, subequal, ovate, pubescent adaxially as well; stamens 9, all 2-celled, pubescent, c. 1.5 mm long, the filaments about as long as the anther cells, the connectives prolonged beyond the anther cells; stamens shorter than the tepals and hidden behind them; paired glands at the bases of the inner three stamens globose, c. 0.4 mm in diameter; staminodia c. 0.6 mm long, ovate; pistil glabrous, c. 2 mm long, the style not exerted; receptacle cylindric, pubescent at the rim, otherwise glabrous. Fruits spherical or somewhat flattened, 2.0- 2.5 cm in diameter × 2.0- 2.1 cm high (dried), reddish to black at maturity, the pericarp 1.5- 2 mm thick (dried), the embryo golden yellow to orange in cross-section.


Cited as [ Cryptocarya   sp. “glauque” (Munzinger 5832)] in Munzinger (2013). Most of the collections identified by Kostermans (1974) as Cryptocarya leptospermoides Kosterm.   belong to this new species.
