One of the isolectotypes (P00602555) was annotated by the author in 2005 mistakenly as “lectotype”, instead (correctly) of “isolectotype”.

DESCRIPTION

Shrubs or trees

1.5- 10 m.

Branchlets

Terete to compressed, surface developing small dark rectangular flakes; internodes> 5 mm.

Leaves

Coriaceous, 2 per node; petioles 2-6.5 mm, sulcate; blades 4.0-8.5 × 1.7-3.8 cm, elliptic, base cuneate, surface flat, margin slightly revolute, apex obtuse or retuse, midnerve above sulcate, secondary veins above raised prominently, oil glands of lower surface dense (and of uniform size), prominent.

Inflorescence

2-5.5(-8) cm, pedicels (1.5-) 5-9 mm, a simple cyme, raceme, or panicle, terminal or axillary; extrafloral bracts leafy.

Bracteoles

1.3-2 mm, linear to narrowly elliptic, sparsely to densely sericeous.

Hypanthium

Calyx

Lobes 5, 1.3-2.5 mm, broadly rounded to almost truncate, sericeous to densely sericeous above and below, green.

Petals 4.5-6 × c. 5 mm, somewhat tomentose above and below.

Filaments 2.5-4 mm; anther sacs 0.5-0.8 mm.

Style

c. 4 mm, lower half villous. Fruits (material scant) 5-6 × 5-6 mm, dark blue-black, globose, base rounded; seeds 1-2.

REMARKS

Gossia pancheri is the second most common member of the genus in New Caledonia after Gossia vieillardii . It is common in the southern part of Grande Terre but ranges north to Mt. Colnett.

The best distinguishing characters include the raised secondary and tertiary venation of the leaves, the thickly coriaceous texture and often glossy sheen of the upper leaf surface.

The species most closely resembles Gossia kaalaensis sp. nov., but that species has narrower leaves, a more acute leaf apex, and a glabrous ovary apex. Some specimens (e.g., MacKee 28691 and 42493) have more densely pubescent and somewhat smaller flowers, but these differences are merely quantitative.
