5. A. tetragonophylla (four-angled phyllodia), F. v. M. in Journ. [Ann. 
Sac. iii. 121 (under A. sphacelata), and Fragm. iv. 8 ; Bentli. FI. Austr. ii. 880 ; F. 
v. M. lc. Dec. i. 7. A tall spreading shrub or small tree, glabrous ; branches terete. 
Phyllodia usually clustered on the old nodes, linear-subulate, rigid, pungent- 
pointed, | to lin. long or rarely more, with 1 or 2 nerves on each side. Stipules 
small, deciduous. Peduncles solitary or 2 together, nearly as long as the 
phyllodia, bearing a globular head of numerous (often above 50) 5-merous 
flowers. Sepals linear-spathulate, half as long as the corolla. Petals smooth, 
usually cohering to the middle. Pod much curved or twisted, flat with thickened 
margins, nearly 8 lines broad. Seeds longitudinal ; funicle yellow, shortly 
flexuose and much thickened at the base, then completely encircling the seed in a 
single fold more or less dilated the whole length. 
Hab.: Bulloo Biver, J. F. Bailey. 
6. A. juniperina (Juniper-like), Willi. Spec. PI. iw 1049; Benth. FI. Austr. 
ii. 381. A rigid bushy divaricate shrub, attaining several feet, the branches 
pubescent or in some varieties glabrous. Phyllodia scattered, often numerous, 
divaricate, linear-subulate, rigid and tapering into a pungent point, rarely above 
Jin. long, with a prominent nerve on each side and a rather broad base. 
Peduncles often exceeding the leaves, bearing each a dense globular head of 
numerous (20 to 50) flowers, mostly 5-merous. Bracts more or less acuminate. 
Sepals narrow-spathulate, at first united but readily separating. Petals also 
separating, smooth but with prominent midribs. Pod more or less falcate, flat, 1 
to 2in. long, about 2 lines broad, usually contracted between the seeds. Seeds 
longitudinal, the funicle but little folded and filiform to the end. — Mimosa juni-

Hab.: Moreton Island and Brisbane Biver, F. v. Mueller. Flowering in October. 
Var. Brownei. Branches glabrous ; peduncles slender. — A. acicularis, B. Br. in Ait. Hort. Kew 
ed. 3, v. 460, not of Willd.; altered to A. pugioniformis, by Wendl. in Flora, 1819, 139, but not

A. genistifolia, Link, Enum. Hort. Berol. ii. 442 ; DC. Prod. ii. 449, above referred with doubt 
to A. trinervata, may, from the very incomplete description given, be almost equally referable to 
some forms of A. juniperina. — Bentli. 
7. A. Bynoeana (after Dr. Bynoe), Bentli. inLinnaa , xxvi. 614, and FI. Austr. 
ii. 337 ; F. v. M. Ic. Dec. iii. 11. Shrubby, with numerous branches, loosely 
pubescent and sometimes glutinous. Phyllodia numerous, linear-terete, striate 
with several nerves, usually recurved at the point, rarely above lin. long 
Stipules small, deciduous. Peduncles 3 to 4 lines long, bearing each a small 
globular head of about 20 flowers, mostly 5-merous. Calyx with narrow ciliate 
lobes. Petals narrow, smooth, not much longer than the calyx and quite distinct. 
Pod much curved, flat, with thickened margins, scarcely above 1 line broad. 
Seeds oblong, longitudinal, the last fold of the funicle, and sometimes part of the 
next also, thickened into a fleshy aril. — A. leptophylla , F. v. M. Fragm. iv. 9. 
Hab.: Gulf of Carpentaria, F. v. Mueller. 
These specimens are alluded to by F. v. Mueller, PI. Viet. ii. 12, as nearly resembling A. Wil- 
helmsiana. The corresponding ones, both in Herb. Hooker and in Herb. Sonder, were, by some 
mistake, labelled as A. Wilhelmsiana from the Murray scrub, and were mentioned by me in 
Linnsea, xxvi. 613, as a var. of A. nematophylla , F. v. M. The latter is, however, a short-leaved 
form of A. calamifolia, which has never more than 1 nerve on each side of the phyllodium. —
