Between lat. 22° 30' and 28° S., and long. 136° 30' and 139° 30' E., By 
OH* W INNEOKE, ESQ., 
DURING HIS EXPEDITION IN 1883 ; 
EXAMINBI) BY 
BARON FERD. VON MUELLER, K.C.M.G., M.D., Ph.D., F.R.S. 
Lepidium papillosum, F. v. M. 
Erysimum Blennodia, F. v. M. 
Capparis Mitchelli, Lindley. 
Capparis lasiantha, R. Brown. 
Drosera Indica, Linne. 
Owenia acidula, F. y. M. 
Borgia perennis, F. v. M. 
Tribulus Ilystrix. R. Brown. 
Zygophyllum Howittii, F. v. M. Petals about £in. long; 
filaments without appendages ; anthers when fully 
opened almost roundish ; radicle often three times as long 
as the cotyledons. 
Vrodium cygnorum, Nees. 
Gossypium australe, F. v. M. 
Lavatera pleboja, Sims. 
Ahutilon leucopetalum, F. v. M. A variety with yellow petals 
of nearly 2in. in length ; some of the stamens fully as 
long ; upper part of the styles exserted ; fruit not seen. 
This plant offers an approach to A. exoncmum, Mons. 
Thozet, sent from M uellersville, specimens with flowers 
fully 3in. long. 
Melhania incana, Heyne. 
Seringea integrifolia, F. v. M. 
Triumfetta AVinneckeana, F. v. M. Leaves roundish or 
verging into an oval form, denticulated and somewhat 
crisp at the margin, velvety on both sides ; sepals 
narrow, dorsally terminated by a minute conical append- 
age, petals downy towards the base ; stamens numerous ; 
ovary three-celled ; fruit large, on slender stalklet, 
almost globular, indehiscent, thinly tomentose, copiously 
beset with long spreading bristlelike, nearly glabrous at 
the summit, hooked prickles. The nearest affinity of 
this plant is with T. leptacantha, but the fruits are much 
larger and not glabrous ; indeed, they are in size similar 
to those of T. procumbens, but provided with longer and 
much more slender prickles. Leaves and flowers have 
been described from mere remnants adhering to the fruit. 
Frankenia laevis, Linne. 
Claytonia Balonnensis, F. v. M. 
Atriplex leptocarpum, F. v. M. 
Atriplex Muelleri, Bentham, var. lobaticarpa ; dwarf, pro- 
cumbent or ascendent, leaves small ; fruitbearing calyces 
minute, to the middle bivalved, digitate or flabellate, 
rhomboid, anteriorly cleft into five deltoid- semilameolar 
lobules, the lateral of which divergent or recurved but 
often abbreviated, the lower portion of the fruit-calyx 
thickened towards the middle but not appendiculated. 
This may possibly require specific separation, but the 
degree of variability of the group of saltbushes to which 
this plant belongs needs yet further to be studied in the 
field or from augmented museum material. The plant 
here under consideration reminds us also of A. fissivalve, 
from which it differs, in less succulency, smaller leaves, 
less transparent, and less deeply valvate fruit-calyces, 
with shorter lobules without dorsal appendages. 
Kochia triptera, Bentham. 
Salsola Kali, Linne. A variety with flowers and fruits 
crowded headlike on abbreviated branches ; appendages 
of calyx minute. 
Ptilotus latifolius, R. Brown. 
Ptilotus alopecuroidens, F. v. M. 
Ptilotus abovatus, F. v. M. 
Polygonum plebejum, R. Brown. 
Prumex crystallinus, Lange. Some of the plants only lin. 
high, though fully in fruit. 
Macgregoria racemigera, F. v. M. 
^Isotropis Wihneckei, F. v. M., in Melb. Chemistry, Febr., 
A 1881. An entirely new plant. 
Crotalaria dissitiflora, Bentham. 
I’soralea patens, Lindley. 
Indigofera viscosa, Lamarck. 
Sw'ainsona laxa, It. Brown. A variety with somewhat larger 
flowers ; lobes of the calyx considerably shorter than the 
tube, the two upper rather blunt ; lateral petals dark 
violet-colored towards the summit ; stipe of pod slightly 
longer than the calyx. 
Glycine sericea, Bentham. Reminds of Gelactia tenuiflora. 
Petalostylio labicheoides, R. Brown. 
Bauhinia Leichhardtii, F. v. M., var. cinerascens. In this 
singular variety the rust-colored silky vestiture of the 
calyces and petals is replaced by a thin dull- greyish 
tomentum. The same form has been obtained on Julia 
Creek, a tributary of the Flinders River, by Mr. Armit ; 
there particularly the petals become glabrescent. The 
leaflets are narrower than usual. Fruit for further com- 
parison is not available. The far extratropis Bauhinia of 
Cooper’s Creek is B. Carronii. 
Neptunia gracilis, Bentham. 
Aoacia dictyophleba, F. v. M. Young pod broad-linear, 
viscid, straight, flat, not hairy, somewhat thickened at 
the margin ; stipe short. 
Calycothrix longiflora, F. v. M. This has recently been also 
collected within the limits of New South Wales, near the 
Warrego, by Mr. Betchc. 
Melaleuca glomerata, F. v. M. Flowers small ; tube of calyx 
thin-velvety, lobes short and blunt ; petals tender-mem- 
branous, almost colorless, ciliolated, otherwise glabrous ; 
stamens when dry pale-yellowish, five to seven in each 
bundle ; the connate portion about as long as the petals, 
but much shorter than the free portions of the filaments. 
Eucalyptus gamophylla, F. v. M. On the specimens now 
collected the upper leaves become narrow lanceolar, con- 
tinuing opposite or getting scattered. 
Eucalyptus microtheca, F. v. M. 
Lythrum hyssopifolium, Linne.
