72. A. Wickhami (after Capt. Wickham), Benth. in Hook. howl. Journ. i. 
379, and FI. A ustr. ii. 392 ; F. v. M. Ic. Dec. xi. 6. A glabrous shrub, often very 
glaucous or resinous ; branchlets angular-striate. Phyllodia numerous, obliquely 
ovate or falcate-oblong, obtuse with a small oblique glandular point, rarely 
exceeding 4in., coriaceous, undulate, with several nerves all very faint or 1 or 3 
more prominent. Spikes pedunculate, | to | or rarely lin. long, densely cylin- 
drical. Flowers mostly 5-merous. Calyx thin, broadly sinuate-toothed, fully 
half as long as the corolla. Petals united below the middle, the midrib 
prominent. Pod flat, but thick and woody ; obliquely veined, about 2in. long, 
2 lines broad above the middle, gradually tapering at the base and recurved at the 
end. Seeds oblique, oblong ; funicle straight, gradually thickened from the base 
into a narrow-turbinate aril, not at all folded. 
Hab.: Islands of the Gulf of Carpentaria. 
The more or less prominent nerves, the glaucous hue, or resinous exudations, very different in 
parts of the same specimen.- — Benth. 
73. A. lysiphloea (referring to the flow of resin), F. v. M. in Journ. Linn. 
Soc. iii. 137; Benth. FI. Anstr. ii. 393; F. v. M. Ic. Dec. x. 4. “ Urr-tee,” 
Palmer River, Both. A rigid shrub of several feet or small tree, glabrous or 
nearly so, often very resinous. Phyllodia rather crowded, erect, obliquely linear- 
oblong, linear or oblanceolate, mostly obtuse but with a short rigid straight or 
oblique point, narrowed at the base, 4 to lin. long, thick and rigid, with 3 to 5 
obscure or more or less prominent nerves. Spikes pedunculate, f to lin. long, 
slender but dense. Flow’ers mostly 5-merous. Sepals very short, thin, shortly 
united at the base. Petals shortly united, the midribs prominent. Pod flat, 
oblique or falcate, 1 to 2in. long, J to ^in. broad, hard and almost woody, 
reticulate and resinous. Seeds ovate, oblique ; funicle with one long fold and 
then thickened into a small aril under the base of the seed. 
Hab.: Islands of the Gulf of Carpentaria, It. Brown. 
Some of the narrow-leaved specimens have some resemblance to A. linarioides, but the fruit is 
very different. — Benth. 
Twine made from the bark, and wood used for making spears. — Both. 
74. A. linarioides (Linaria-like), Benth. in Hook. Bond. .Journ. i. 371, and 
II. Anstr. ii. 393. Glabrous or slightly pubescent and viscid, with terete 
branchlets. Phyllodia rather crow'ded, linear, obtuse, with a small rigid but not 
pungent point, f to lin. long, not above 1 line broad, obscurely 1-nerved. 
Spikes slender but rather dense, shortly pedunculate and exceeding the phyllodia. 
Flowers mostly 5-merous. Sepals small, thin, free or slightly connate at the 
base. Petals connate to the middle, with thickened tips. Pod linear, slightly 
curved, 14- line broad at the seeds and contracted between them, the valves 
convex, rigid, obscurely striate, with thickened nerve-like margins. Seeds oblong, 
longitudinal ; funicle with the last 2 or 3 folds thickened into an irregularly cup- 
shaped aril under the seed. 
Hab.: Cavern Island, Gulf of Carpentaria, B. Broion. 
This species has small 5-merous dowers and nearly the phyllodia of A. lysiphloea, with the pod 
more allied to that of A. longifolia and its allies, but more rigid. — Benth. 
75. A. Chisholmi (after W. R. Chisholm), Bail. Ql. Ayri. Journ. iv., part 1. 
Plant very resinous, branches slightly pubescent, and more or less corrugated. 
Phyllodia linear, about lin. long and scarcely exceeding J line broad, apiculate, 
often somewhat falcate, slightly hairy. Spikes erect, rather slender, about 4 or 5 
lines long, upon ‘a slender peduncle of an equal length. Flowers crowded, 
5-merous. Sepals small, hyaline, only connate near the base. Petals twice as 
long as the sepals, free almost to the base, colour a deep-yellow. Stamens 
numerous ; filaments flexuose, slender. Ovary scaly, style flexuose, exceeding 
the stamens. Pod linear, slightly curved, about 24in. long and 3 lines broad,
