Callerya neocaledonica I.C. Nielsen & Veillon View in CoL , sp. nov.

Species nova generis Calleryae characteribus sequentibus distinguibilis: stipulis filiformibus, stipellis praecociter caducis, rachide foliorum dense puberula, 2.5-5 cm longa, panicula c. 8-10 cm longa, c. 6 cm lata; dentibus inferioribus calycis late triangularibus, superioribus lobum emarginatum formantibus, vexillo basaliter callosifero.

TYPUS. — J.-M. Veillon 7466, Nouvelle-Calédonie, Dumbéa , Nakutakoin, western slope of Pic Jacob, c. 150 m, 15 Jan. 1992 (fl.) (holo-, P; iso-, AAU, NOU).

Woody liana, 8 cm in diameter at base, the young shoots pubescent, glabrescent; bark grey, rough, the inner reddish coloured by a very sticky red mucilage. Stipules filiform, acute, c. 3 mm long, early caducous. Leaves: rhachis 2.5-5 cm long, densely puberulous, stipels not observed, petiolules c. 2 mm long, densely puberulous; leaflets 7, elliptic to obovate-elliptic, 2-6.2 cm long, 1-2.8 cm wide, apex rounded to obscurely acuminate, upper surface glabrous except for a few hairs on midrib and ciliate along the margin, lower surface with scattered appressed hairs, venation densely reticulate on both surfaces, secondary nerves (5-)7 pairs, marginal arches near margin, variable. Inflorescences of terminal panicles on leafy lateral shoots, main axis c. 8-10 cm long, densely puberulous, lateral branches up to 3 cm long, pedicel c. 0.7 cm long, bract ovate, 1.2 mm long, cuspidate, densely sericeous, early caducous, bracteoles on top of pedicel, filiform, 1-1.2 mm long, densely sericeous, early caducous. Flowers violet: calyx broadly cup-shaped, densely sericeous, tube 3 mm long, oblique, three lower teeth c. 1.2 mm long, broadly triangular, upper lip slightly emarginate. Petals violet, clawed. Standard blade reflexed, sub-circular in outline, 14 mm long and 16 mm wide, auricled, emarginate, densely sericeous outside, and with two callosities inside at base, nectar guides present (yellow), claw 1-1.2 mm long; wings semi-pandurate, c. 15 mm long, exceeding the keel with 1 mm, ciliate along the upper margin, lower auricle indistinct, upper auricle c. 2.5 mm deep; keel c. 14 mm long, blade semi-pandurate, 10-10.5 mm long ciliate along the upper margin, claw 3.5-4 mm long, upper auricle present, lower absent; stamens c. 12 mm long, tube c. 10-11 mm long; disc c. 0.5 mm high, indistinctly lobed, surrounding the base of the ovary; anthers dorsifixed; ovary sessile, c. 8 mm long, sericeous, style curved, c. 5 mm long, stigma minute and capitate. Pod not observed. — Fig. 1. View FIG

FIELD NOTES. — Liana, at base 8 cm in diameter, with blood-red sap, which is visible in the old parts only. Inflorescence terminal or axillary, consisting of flower-rich panicles. Standard with yellow spot, flowers violet becoming white after anthesis.

DISTRIBUTION. — New Caledonia.

HABITAT AND ECOLOGY. — Phtanite rocks, soil dark brown. Sclerophyllous forest on slope. Altitude c. 150 m.

NOTES. — The species has not yet been collected with fruits. It is a good match of Callerya australis . The specimen shares the facies of Callerya australis (Endl.) Schot (syn. Pterocarpus australis Endl. , Millettia australis (Endl.) Benth. ) which is distributed in New Guinea, Norfolk Island, Rarotonga, and Australia (Queensland) ( VERDCOURT 1979). C. neocaledonica differs from C. australis in the following characters: stipules filiform (narrowly triangular in C. australis ), stipels early caducous, if present not to be observed in mature leaves (persistent in C. australis ) rhachis of leaves shorter 2.5-5 cm vs 9- 15 cm, leaflets 7 vs 7-13, panicle c. 8-10 by c. 6 cm vs terminal panicles 16-30 cm long. Lower calyx teeth broadly triangular and the upper two forming an emarginate lip vs calyx teeth all triangular acute/acuminate, basal callosities in standard present vs absent.

A collection, McKee 45807, Dumbéa, southwest slope of Pic aux Chèvres, sclerophyllous forest on steep slope, c. 100 m (12 May 1992), sterile (AAU; NOU; P) probably belongs to this genus. It has up to 19 leaflets, that are smaller than in the present species, but as it is sterile it is not possible to decide upon its affinity at present.

PARATYPE. — J.-M. Veillon 7086, New Caledonia, Nakutakoin, south-west slope of Pic Jacob ; more or less sclerophyllous forest on steep slope; large, robust liana, with blood-red, liquid latex, ster., 11 Aug. 1989 ( AAU, NOU, P) .
