Discussion
The photo of the holotype at K deposited at N Y shows the broad ovate leafblades with subacuminate apex and rounded base and few lateral nerves as described for this species. However, the photo from B at F has two discordant elements shown mounted on the same photo: the upper fragmentary branch is the broad-leaved, few-nerved 31. panurensis with acute apex and rounded leaf-base; the lower fragmentary branch has oblong leaf-blades which are rounded to obtuse at the apex and subacute at the base, and with 9 lateral nerves on each side which are definitely sulcate on the upper surface. On the upper specimen of the B photo the true 31. peinuren.sis specimen has an evident flowering rachis with all the glomerules of flowers sessile, the inflorescence as a whole 2.7 cm long. The lower specimen on this photo does not belong with M. panurensis, and represents a different species.
