A desert species allied in habit and characters 
closely to Pimelea pauciflora, a common

Stuart’s Creek. Common on clayey river 
banks and other argillaceous localities 
subject to inundation throughout the 
greater portion of the interior. 
A curious variety with nmnerous short di- 
varicate spinescent branchlets and with 
smaUer almost octaedrous fruit occurs in 
the collection.

Sepals of the specimens from the above 
locality, only three or four times longer 
than the bractcoles ; the inner ones to- 
mentose at the back, and blunt at the 
apex. 
This species is ^jerhaps to be united with T.

TriMni um ■parvifolixm. 
Branches verg nmierousy spreading, and 
leaves glabrous ; leaves veig minutey errate 
acute, the upper ones mucronate ; dower- 
heads nearly globose, terminal, solitary ; 
calyx rather small, three times longer 
than the bracteoles, towards the top j)ink, 
densely clothed with remotely articulate 
villi ; bracteoles hyalinous, oue-nerved, 
round, with a mucronulate acumen, to- 
wards the base vOlose-tomentosc ; fila- 
ments very narrow, linear and style gla- 
brous j anthers oval. 
Stuart’s Creek. 
The plant, to judge from the fragment in the 
Expeditiondierbarium, seems 8h^ubb\^ 
Branclilets thin, streaked. Leaves only 
-1^ long, more distant in the upper part 
of the branchlets. Sepals scarcely 
long, all acute. Rachis tomentose. Villi 
extremely tender. Style hardly as long 
as the sepals, longer than the stamens. 
Similar as regards flowers to T. roseum. 
Villi less rigid, not quite as much spread- 
ing, nor reaching nearly to the summit of 
the sepals. In regard to its ramification 
and the minuteness of its leaves from 
every other species widely distinct, unless 
it should prove' to be one of those re- 
markable abnormities, which plants after 
the accidental loss of their Iffading stem 
sometimes jmoduce by prolific growth.

Lake Gregory and common on sand ridges 
of the Murray desert, and near Spencer’s 
and St. Vincent’s Gulf. 
T. pachycephalum seems to me a variety 
of T. angustifoliuin, which inhabits the 
basaltic jtlains from Newcastle Range 
(lat. 18® S.) to the Southern Glenelg River 
(lat. 38® S.) 
In all the numerous species of this genus 
which I liad an opportunity of examining 
I observed constantly one or more of the 
stamens sterile, the same observation 
having been previously made positively 
on T. mucroiiatimi and indirectly on 
T. sericostachyum and T. villosum by 
Nees, and also indirectly on T. erube- 
scens by Scblecbtcndal. (Linnaja XX, 
575). These staminodia produce in some 
species barren anthers, in others not, 
and it appears that from this character 
and tlie length of their filamcntvS good 
marks of discrimination between the dif- 
ferent species can he derived. Even in 
Trichinium spathulatum I noticed the 
dissimilari^ of the stamens, although the 
beautiful plate of this plant, in J. Hooker’s 
Flora Tasmanica, famishes a contradiction 
to this statement, so that the above 
character may possibly be subject to 
exceptions. It is however now sufficiently 
evident that Hemisteirus (Linnaia XXV, 
435) stands in close relationship to Tri- 
chinium.

nt a span liigh seemingly with an annual 
root. Leaves about 1" long and broad. 
Fruit long, with no discernible sutures, 
to indicate a valvate stmeture. Seeds 
brown, shining. Eadiclo superior. 
Closely allied to A. iuflatum. 
The leaves more tender and broad ; fruit 
not appendiculate, but in a similar manner 
spongy and reticulate. This and several 
other species with valveless spongy fruit 
deserve perhaps to be transferred under 
the sectional name into a separate genus.
