- Diagnosis
- Male inflorescence. This consists of a compound catkin, the axis of which is 13*8 cm. long. The axis is 5*5 mm. wide at its base, and tapers gradually to about 1 mm. at its apex. It is flexuous, pendulous and forms almost a semicircle. The staminate buds alternate and are arranged distichously on the axis. One portion of the axis near to the apex is devoid of buds, which have probably fallen off before coming to rest in the mud. The buds, of which there are thirteen, are sessile and those which are well-preserved consist of a number of imbricated scales arranged in cup-like form from the centre of which spring several microsporophylls arching over to the centre of each bud. The largest bud, which occupies a position near the base of the axis, is 1 9 cm. long and 1'5 cm. wide. The buds gradually diminish in size towards the apex of the catkin. The scales are keeled, longitudinally striated and are about 10 mm. long and 3 mm. wide. Each scale terminates in an acute point. In a few cases bracts can be seen, from the axils of which spring the buds.
