connate to form a tube about the length of the corolla; a few 
bristles (similar to those of the ray-florets) extend beyond the 
tube for the whole length of the corolla. Style and style-branches 
nearly two times as long as the corolla; the style-branches nearly 
‘terete, with obtuse elongated clavate tips, papillose on the back. 
Anthers obtuse at the base. Achenes abortive. 
Habitat.—Mount Lyndhurst Run near Farina, South Aus- 
tralia ; discovered by Mr. Max Koch, who has had the species 
under observation for two flowering seasons. 
The floral characters presented by this new plant are in the 
main proper to Minuria ; and of the five species which are com- 
‘prised in the genus (restrictively Australian), it makes some 
-approach to I. suaedifolia by its yellow flowers and connate 
pappus of the disk-florets. But the species differs from all of 
them by its herbaceous habit, and more particularly by its lateral 
(not terminal) flower-heads; the long corolla-tube of the ray- 
‘florets is a further difference, though one of degree only, and 
therefore not of generic value. 
Nevertheless, the species typifies a new section or subgenus, 
‘for which I propose the name MINURIELLA (diminutive of 
Minuria, in allusion to its dwarf and herbaceous habit). 
GENUS ZYGOPHYLLUM. 
Before proceeding to the diagnoses of certain new forms in the 
-genus, I will make some general observations on those characters, 
presented by known species inhabiting Australia, which are 
-employed in the discrimination of the species. 
_ Mueller admits nine species, to which I add two; these may 
‘be grouped into two series on the differential characters afforded 
by the filaments, shape of capsule, and fioral taxonomy. 
Bentham, in “Fl. Aust.,” L, p. 292, employed the first 
character to distinguish the primary subdivisions; Mueller, 
“Vict. Plants,” the last; and I, in my “Flora 3. Aust.,” the 
‘second. The species included under these several schedules are 
-as follows :— : 
FILAMENTS. 
1. Basal part of filament winged. 
Apiculatum, glaucescens, crenatum, iodocarpum, prisma- 
tothecum, Kochii, hybridum. 
. Filaments subulate, not winged. 
Bulardieri, ammophilum, fruticulosum, Hou ttti. 
bo 
FRUITS. 
. Capsule obconic, truncate atop. 
Apiculatum, fruticulosum, ammophilum, Billardieri. 
. Capsule globulose, oval, or oval-oblong. 
Prismatothecum, Howitti, glaucescens, crenatum, iodocar- 
pum, Kochi, hybridum.
