390 XL. LEGUMiNOSiE. * [Jcacia, 



. 201; A. excelsa, SenfL in MitcL Trop. Austr. 235. . A large forest- 

 tree; branclilets slender, terete or nearly so, glabrous or rarely minutely pu- 

 bescent. Phyllodia oblong-falcate, rather obtuse or mucronulate, narro^ved 

 at the base, 2 to 3 in. long, \ to | In. broad, thuily coriaceous, with 5 to 7 

 nerves, and smooth or faintly veined between them. Peduncles solitary, in 

 pairs or clusters, sometimes not 2 lines, in other specimens nearly 2 in. 

 Ions, bearing each a globular head of numerous (20 to 30) flowers, mostly 5 



merous. Sepals distinct. Petals smooth. Pod straight, flat, about 3 lines 

 broad, thinly coriaceous, the sutures narrow-edged or almost winged, not 

 usually dehiscent but hardening over the seeds and readily breaking off be- 

 tween them. Seeds ovate, lohgitudinal ; funicle short and filiform, neither 

 folded nor enlarged. — A, Baintreana^ ¥, Muell. Fragm. iv. 6, 



Queensland. Near Lake Salvator, Mitchell; Peak Downs^Z Maeller ; Clarke river, 

 Dairdree ; also in Bowman s coUectiOn. Very closely allied to, and perhaps a variety of, 

 A, laurifolia, Willd., from New Caledonia and the Pacific islands, differing chiefly ia the 

 narrower phylbdia and pods. 



202. A. coxnplanata. A, Cnnn. ; BentJi. in HooTc. Lond, Jonrn, i. 369. 

 A tree, glabrous; branclilets flattened, bordered by 2 or rarely 3 acute 

 angles or narrow wings. Phyllodia oval or oblong, obtuse, 2 to 3 in. long, 

 ^ to 1 in. broad, thinly coriaceous, with 5 to 9 or even more longitudinal 

 nerves and a few fine veins between thena. Peduncles slender, about 2 ^^• 

 long, in axillaiy clusters often of 6 to 8' or more, or by the abortion of tlie 

 upper phyllodia forming an irregular terminal raceme, bearing each a globular 

 head of numerous flowers, mostly 5-raerous. Sepals free, spathulate. Petals 

 smooth, free. Pod curved, acuminate, veiy flat, 3 to 4 lines broad, the upper 

 suture nerve-like or with a narrow border. Seeds oblong ; funicle in tbe 

 Banksian specimens short and not dilated, but not quite perfect, in F. Muel- 

 ler's specimens elongated, more or less dilated from near the base, ^^^^1 e"^J,^' 

 cling the seed in a single fold.— ^. anceps. Hook. Ic. PI, t. 167, not of Db.

G. Dimidiate.— Phyllodia usuallv broad and often long, falcate or veij 

 oblique, with 2 or 3 prominent distant nerves and retieulately penniveme 

 between them. Stipules minute or none. 



These correspond with the i»uhseries Dimidiates of J«A>f(?/^, differing in their capitate^^^^ 

 florescence. The phyllodia are much larger and more oblique than in the ^^'9^'^^'^^^\--^^ 

 the stipules are not 'spluescent as in A. urophylla amongst Armata, which has somei 

 large phyllodia. 



203. A. binervata, DC Prod. ii. 452. A tall shrub or a tree, attain- 

 ing sometimes 30 to 40 ft., jrlabrous, with slightly angular brancUets, so 

 becoming terete. Phyllodia falcate, oblong or lanceolate, narrowed at e* 

 end, mostly 3 to 4 in. lorig, with 2 or 3 longitudinal nerves and F""^^^^^ 

 veined between them, the marginal gland below the middle rather ^.^"^jP^j 

 CU0113. Peduncles rather slender, 3 to 8, at first in an axillary racciue, 

 after flowering the raceme often grows ont into a leafy branch with t"^P|^ 

 duncles at the base, each bearing a globular head of about 20 flo^^^""^* "^"^p^; 



5-merous- Calyx scarcely half as long as tbQ corolla, siauAte-tootued.
