Cuscuta australis. R. Br., Prodr., 491 ; Gascoyne River, J. Forrest. The Dodder-plant 
from this region may deserve specific distinction, and lias been marked by me as a 
variety under the name reducta, because the lobes of the calyx and corolla are 
reduced to 3 or 4, and therefore the stamens also to that number; moreover the 
styles are exceedingly short and the capsule enlarges to an unusual width, 
particularly when all four of its turgid divisions are developed. As, however, it has 
been shown by Dr. Engelmann (Transactions of the Academy of Science of St. 
Louis I, 491-494, anno 1859) that Cuscuta australis extends widely through 
America, also to Africa, Asia, and South Europe, and produces sometimes 
tetramerous flowers and broader fruits, I am led to take Mr. Forrest’s plant as an 
extreme form of C. australis. I have it also from Lady Charlotte’s Water (C. 
Giles), from the Finke River (Kempe), and from Cashmere, North Queensland 
(Armit). It occurs, so far as I have seen, on Indigofera monophylla, Vigna 
lanceolata and Tribulus terrestris.

Stemodia viscosa. Roxb. PI. Corom. ii., 33, t. 163 ; Gascoyne River, Polak ; Menilyalya, 
J. Forrest. The large flowered variety. Occasionally 4 or 5 leaves in a whorl. 
From the same locality Stemodia grossa, with a corolla sometimes fully an inch 
long ; but whether that be only a sessile flowered variety of S. viscosa remains to 
be ascertained. 
Peplidimn Mwdleri. Bcnth. Flor. Austr. iv., 500; Gascoyne River, J. Forrest; found 
also between the Finke River and Lake Eyre, by Mr. E. Giles. 
Buechnera parvijiora. R. Br., Prodr., 438 ; Gascoyne River, Polak. Seeds very minute, 
cuneate-ovate, truncated. The plant seems perennial. 
Orobancheae. 
Orobanche Australiana. F. v. M., Syst. Census, 98 ; Peron Peninsula, Gaudichaud. 
(Voyage de l’Uranie et Physicienne, Botan. p. 36). Professor Caruel concurs in 
my opinion, that the Australian Orobanche is not absolutely identical with 
O. cernua, the exact characteristics of which he had ample opportunities to study 
in the South of Europe.
