Distichophyllum semimarginatum Thér.

SPECIMENS EXAMINED. — New Caledonia. North Province, Mont Paníé, ascend along the hiking trail from the street RPN 3 to the

summit, c. 1300 m, very humid rainforest, on wet boulders along a brook, 13.IX.2001, Müller NC56 (DR).

COMMENTS

The species was described by Thériot (1910a) from “Mont Koghis, sur l’écorce des arbres.”, collected by Isidore Franc. In PC,TRH, L, S, BM there are specimens collected here by Franc and determined by Thériot between 1909-1913, type material is in PC, S, and BM. We are unaware of any newer collection apart from these old specimens from the type locality. With the new specimen Müller NC56, we can confirm the presence of this species, endemic to New Caledonia, newly reported for North Province. The species is unique among the genus by leaves bordered only in the lower half and denticulate all around ( Fig. 5 ).
