Dr. Aunandale's specimen consists of the male plant only, and I have not 
thought it desirable therefore to give it a name as in the absence of the 
female plant it is not possible to draw up a satisfactory description, or to 
compare it with the allied Australian species. It is a striking plant with 
fertile whorls about 20 mm. in diameter invested in a dense mucilaginous 
cloud. The stem is about 750 p in diameter, the branchlets usually 8, twice 
or three times forked, with about 8 rays at the first forking ; the penultimate 
rays are not much shorter than the daetyls which are about 6 in number, 
elongated, of about equal length, the lower cell slightly narrowing at the 
apex, the apical cell very narrow and acute. The antheridia, about 450 y in 
diameter, are produced at all the nodes, though less frequently at the first 
node. 
It is much to be hoped that the plant may be again collected, so that 
female examples may be obtained.
