AND ANATOMY OF THE GENUS RESTIO. 221 
interior of one compartment of the fruit, from the upper and inner 
angle of which it is suspended by a very short funiculus; in form 
it is usually oblong, obscurely three-sided, slightly pointed at the 
upper end, flattened and somewhat quadrangular below. The 
testa is cartilaginous, greyish in colour, usually covered with 
minute pits, between which are interspersed purplish spots; in 
other cases the testa is studded with small whitish tubercles, 
giving the seed the aspect of being studded with minute pearls. 
The perisperm is very copious, white, horny or somewhat fari- 
naceous. 
The embryo is a small lenticular fleshy mass placed in a little 
socket, at that end of the seed most remote from the hilum. 
Teratology.—All the Restiaces appear to be subject to the occa- 
sional presence of bud-like aggregations of scales, like the bracts, 
but destitute of flowers. They are frequently found replacing the 
true inflorescence, and may be arranged in spikes or panicles. 
They are by no means confined to the inflorescence or to the fertile 
culms, but may be met with proceeding from the axils of the 
sheaths of the stem, or in the angles between two diverging 
branches. The scales in these instances are generally closely 
packed, but occasionally the central axis lengthens, and then the 
scales become separated by greater or less intervals one from 
another. These growths are of similar nature to those that occur 
in the so-called Rose Willows and other plants. Monecious 
specimens sometimes occur, as has been before stated. In one 
instance only have I seen a truly hermaphrodite flower of Restio, 
and this occurred in a fragment of an undetermined species. In 
Lepyrodia hermaphrodita this condition is common, and it also 
oceurs, though very rarely, in other genera. 
Minute Anatomy.—Sections of the root of R. triflorus, made in 
various directions, exhibit on the outer surface an epidermal layer 
destitute of stomata; subjacent to this are three or four rows of 
large, loosely-packed oblong cells, polygonal on cross section, and 
having slightly thickened walls ; these again encircle a thick layer 
of pitted liber-cells, which are of a deep-brown colour. In the 
centre is a cylinder of wood-cells, with thick walls and few, if any, 
pits; intermingled with these are a small number of slit-marked 
ducts. 
The structure of the rhizome is very similar to that of the root ; 
there is a similar thick dark-brown epidermis covering a layer of 
very large dark-coloured liber-cells. The great mass of the root- 
stock, however, consists of oblong or polygonal, thick-walled,
