in F. laevis, but are several times the volume of the latter, which fact, 
however, seems not to have made an appreciable difference in the capacity 
for distribution. In the matter of plant habit, certain more erect forms of 
F. pauciflora constitute prominent bushy growths of the height of one meter. 
Even more interesting because of its relationship is F. serpyllifolia !) 
Lindl., placed by Benruam as a variety of F. pauciflora. F. serpyllifolia is 
an annual prostrate plant exactly corresponding to F. pulverulenta of 
the Med. region and F. grandifolia of California and Chili, with the latter 
of which it coincides strikingly in appearance. But although so nearly 
related, it is separate from both. The chief distinguishing character is 
found in the seeds which, have unusually conspicuous epidermal papillae. 
The seeds of F. pulverulenta are very minutely papillate, those of F. gran- 
difolia very large, reddish and mostly smooth. While the specimen of 
F. serpyllifolia examined has seeds two or three times the volume of 
F. pulverulenta with papillae half as long as the breadth of the seed itself, 
which give it a grayish, hairy appearance. 
Toichogonia isolata. 
This section is represented in Australia by the two species F. parvula 
Turcz. and F. punctata Turez. These are two prostrate shrubby species 
from West Australia, in which region all of the peculiarly Australian species 
oecur and so far as reported not elsewhere in the continent. Each of these 
species receives its peculiar distinction from its method of developing leaf 
struetures, which in F. parvula are very minute, 1—11/; mm long, of the 
Beatsonia type as to form and manner of folding, but with the peculiar 
quelling cellulose layer in the epidermis which is most pronounced in 
F. bracteata, but which is developed in most of the strictly Australian type. 
The leaves of F. punctata are of a form which is not found elsewhere 
in the family. These occur in isolated pairs at the nodes, where being 
coalescent, they form an inconspicuous sheath. Instead of having the 
lamina developed at the upper margin of the sheath the assimilating sur- 
face is developed as a lobe-like appendage lying nearly parallel with the 
stem and closely pressed against it, extending both above and below the 
surface of attachment to the stem and of coalescence with the opposite leaf. 
The floral structure of F. punctata is like Eufrankenia except that the 
gynoecium is bicarpellary. Only one or two pairs of ovules are started 
and probably only two or three seeds matured. 
1) The only specimen I have seen was one collected by Mürter in West Austr., 
which seems to answer to LixpLEv's description of the Drummonn specimen from Mur- 
chison River. It must have been a plant of this species also which pe CANDOLLE (Prod. I, 
350) referred with doubt to F. pulverulenta.
