LOWER DEVONIAN PLANT REMAINS 129 
broad. From the concave side of the axis three short branches 
arise, and it appears to terminate in a flattened, irregular expan- 
sion. The recurrence of this type links the beds under discussion 
with the sandstones of Mount Pleasant and encourages the hope 
that more connected specimens will ultimately be found. 
(c) Stems with Small Spirally-arranged Elevations 
Plate VI, Fig. 25. 
A few short axes with small elevations on the surface or 
depressions (Plate VI, Fig. 25) on the corresponding counter- 
parts have been found at this locality. These are suggestive of 
remains of small leaved stems, but no evidence of leaves or 
spines either at the margins or on the flattened surfaces has been 
seen. The specimens agree in every respect with similar remains 
described and figured from Mount Pleasant but like them can only 
be mentioned as a type of plant-remains and not as evidence of a 
small leaved plant in the Siluro-Devonian rocks of Victoria. 
(а) Smooth Branched Axes 
Plate VI, Fig. 26. 
Small branched leafless axes are abundant in this deposit. АП 
are indeterminate. The one shown in Plate VI, Fig. 26, however, 
has some comparative interest. It is a slender stem which just 
behind the point of bifurcation shows the base of an additional 
branch. Similar specimens were met with at the Centennial beds 
(Lang and Cookson 1930, Fig. 8) and at Mount Pleasant (Cook- 
son 1935, Figs. 17, 18). They were recorded as Hostimella sp. and 
cf. Hostimella sp. respectively. At that time the resemblance to 
Goslingia (Heard 1927) was pointed out. Croft and Lang (1942, 
p. 143), in writing about similar axillary bodies in G'oslingia 
from Llanover Quarry, Wales, stated that ‘‘it is useless at present 
to enter further into the general question of the nature of the 
axilary bodies which are now known to have been present in 
various early plants without being satisfactorily understood in 
any of them." The occurrence of this feature in several types of 
plant greatly reduces its usefulness as a diagnostie feature. It is 
therefore now suggested that the use of the name Hostimella sp. 
for branched leafless stems with axillary bodies be discontinued.
