various features. The leaves on the evanescent basal rosette are three- 
veined instead of five-veined, and the two lateral veins are often very 
faint. The leaves are also smaller and more orbicular, The flowering 
stem is covered with fine closely-set short papillae, especially short and 
dense on the stalk and ridges of the ovary, and on the under surfaces 
of the leaves. The upper leaves on the flowering stem are often more 
than an inch long and nearly quarter of an inch broad, the edges finely 
dentieulate, and contracted to a subulate. brownish, often curved tip 
usually one-eighth of an inch or more in length, but less developed on 
the basal leaves. The labellum is lanceolate, strongly contracted in its 
upper third to a reddish-brown entire tip. The basal appendage is 
curved and irregularly fringed with cilia along its distal third, the ter- 
minal eilium being larger than the rest. In other respects the plant 
bears a close resemblance to P. obtusa, from which however its labellum 
at once distinguishes it. The labellum and flower are like those of P. 
praecox, the leaves, stem, and papillose surface are more like the charac- 
ters of P. reflexa. 
Since a perfect series of gradations exist as regard size of flower, 
length of point of labellum, size and acuminate character of leaves, and 
Scabrous or glabrous character of stem and leaves between P. reflexa 
and P. praecox Lindl, the latter species must be reduced to a variety 
of P. reflexa. P. obtusa R. Br., seems to be distinct, especially as regards 
the obtusely oblong shape of its labellum.

Aizoon intermedium is distinguished by Diels from A. zygophylloides 
(F. v. M), by the shape of the leaves, longer pedicels and narrow calyx 
lobes. It comes very close to some nearly smooth stemmed specimens 
included by F. v. Mueller in A. zygophylloides, and may ultimately prove 
to have not more than a varietal significance. It is, however, quite 
distinct from Luehmann's undescribed Aizoon glabrum. This is a rather 
small plant, spreading more or less from a single root, the slender wiry 
glabrous stems, 2 to 6 inches high, simple or branching one or more: 
times, bearing terminal flowers in loose cymes on short pedicels, one or 
two pairs of linear leaves being close under the flower, which is some- 
times and inch. across when fully open, but usually less. Calyx 4 par- 
tite, usually divided nearly to the base, enlarging during flowering to-
