LEGUMINOSiE. 
ACKSONIA MOLLISSIMA, sp. nov. 
An erect, dense, heavy looking shrub of 8-12 feet in height. The 
branches, branchlets, pedicels, and calyxes closlely invested with short 
appressed silky hairs. Branches prominently angular or almost winged; 
Phyllodineous branchlets linear to linear-lanceolate, straight or falcate, 
almost pungent pointed, of rather soft texture in the specimens seen, 
simple, flat, i-i-£ inch long, central nerve prominent. Flowers, solitary 
or in pairs near the base of the branchlets, or scattered singly along 
their edges, sometimes forming irregular terminal racemes through 
branchlet-suppression. Pedicels nearly as long as the calyx, with 
minute bracteoles below the middle. Calyx 3^-4 lines long, not angu* 
lar in the bud, the segments persistent. Petals as long as the calyx, 
the standard and wings bright yellow ; keel purple. Ovary distinctly 
stipitate, tomentose, 2-ovulate. Pod oblong, falcate, almost acute, 
somewhat turgid, tomentose, 5-6 lines long, on a stipes of about x line. 
Locality . — Margaret River, on hills overlooking Ellensbrook Farm, 
f miles from the coast, in sandy soil overlying limestone. — E. W. 
Hursthouse, March, 1904. 
Remarks . — The ovary and pod of the new species are quite those 
of J '. horrida , DeCandolle, but in other characters it more closely 
approximates J. sericea , Benth. ; differing, besides in the ovary and pod, 
chiefly in the longer flat phyllodineous branchlets, and the pedicels 
and petals proportionately longer as to the calyx. 
MYRTACEJE. 
MICROMYRTUS HURSTHOUSEI, sp. nov.- 
An erect glabrous shrub, of about 2 teet in height, with slender 
twiggy branches. Leaves decussate, loosely imbricate on the short 
branchlets, ovate, obtuse, thick, concave, keeled, f-i line long. Flowers 
small, white, sessile, 1-3 together in the upper axils and forming ovate 
heads or spikes. Bracteoles persistent, linear to linear-spathulate, 
concave, membranous, ciliate, at least as long as the calyx-tube. Calyx- 
tube cylindrico-turbinate, 5 streaked, about J line long; lobes short, 
orbicular, herbaceous, with membranous finely denticulate margins. 
Petals orbicular, f line diameter. Stamens 5, opposite the petals; 
filaments short, filiform ; anther cells globular, opening in terminal 
pores. Ovules 2. Style very short, glabrous ; stigma minute. Fruit- 
ing-calyx of soft texture.
