20. retin6des, Schlecht. A tall shrub or small tree: 

 ph.\!l. lanooolato, with nervo-like margins and nar- 

 ro\vi'(i to liasc, acute, pinnatoly veinod, 3-6 in. long, 

 }4-^4in. wide; gland >4in. from base: fls. in racemes, 

 mostly compound; peduncles Ji'in. long; 30-40 fls, in 

 a hcail: pod flat, with nerve-like margin, 3-4 in. long, 

 about }4in. wide; funicle colored red, encircling seed, 

 bent back upon itself in a double fold and ending in 

 club-shaped aril; ripe June-Oct. Fls, p'eb.-.Sept.. F. y. 

 M. Icon. ,5:9. — Very closely resembhng A. ncriijolin in 

 foliage and fls., but difl'ers in pod, being narrower than 

 that of A. nrriifolia, while the funicle is red and en- 

 circles seed in double fold. 



30. neriifolia, Cunn. A small tree with angular 

 branchlets: phyll. lanceolate, acute, narrowed at both 

 ends, 1' 2-534 in. long, J^-^sin- w'ide, 1 central nerve; 

 gland } 21"- from base: fls. about 40 in a head, .5-merous, 

 in short racemes; sepals 5, separate, ciliate; peduncles 

 3 s-?4in. long: pods with nerve-like margins, contracted 

 between the seeds and often constricted, a rich brown, 

 3-6 in. long, fin. wide; funicle wliite, short, not encir- 

 cling seed, but thickened into a club-shaped aril; seed 

 longitudinal, oval, with central depression. Fls. July. 



31. suaveolens, Willd. A glabrous shrub, 3-6 ft. 

 tall: ph\'ll. hnear to lanceolate, apex acute, tapering to 

 base; 1 central nerve; gland near base: fl. -heads in axil- 

 lary racemes, at first inclosed by imbricate scaly bracts, 

 which soon fall; fls. 6-10 in a head: pod oblong, rounded 

 at both ends, flat, impressed between the seeds, 1-1 1^ 

 in. long, J^-^'sin. wide; seeds transverse; funicle fili- 

 form and suddenly enlarged into fleshy aril at right 

 angles to itself. Fls. Apr. — Superficially it resembles 

 narrow-lvd. A. retinodes, but note the imbricated bracts; 

 the pods are shorter and wider and the funicle does not 

 encircle the seed. 



32. macradenia, Benth. A glabrous shrub, 10-12 ft. 

 tall, or, in favorable situations, a tree 30-50 ft. high: 

 phyll. lanceolate-falcate, narrowed to base, 53 2~12 in. 

 long, 32'"- W'ide; veins fine, prominent and transverse; 

 gland at base, large or often wanting: racemes com- 

 pound, short; fls. small; petals pubescent; calyx more 

 than half as long as corolla, turbinate, toothed and 

 ciliate: pod with nerve-like margin, 2-4 in. long, }^in. 

 wide or more, slightly constricted between the seeds; 

 seeds longitudinal; funicle not enfolding seed but bent 

 upon itself and ending in club-shaped aril, about half 

 as long as seed. F. v. M. Icon 5:7. — A beautiful close- 

 grained wood that is capable of taking a high pohsh. 



33. salicina, Lindl. Small tree; branches drooping: 

 foliage pale; phyll. 2-5 in. long, J^-H'"-. wide, oblong- 

 linear or lanceolate, narrowed at base, thick, rigid, with 

 a curved point; midrib and marginal veins scarcely 

 prominent: racemes short, often reduced to 2 or 3 heads, 

 or even only 1 ; peduncles slender; fls. about 20 in the 

 head: pods straight, 1-3 in. long, Jiin. broad, valves 

 convex, hard antl thick; seeds longitudinal; funicle 

 thickened and usually scarlet almost from the base, 

 forming several folds under the seed. — The timber is 

 dark brown and tough, taking a high poUsh. It is a 

 good forage plant and on this account is becoming 

 scarce in the wild state. 



Var. Wayae, Maiden. Fig. 73. A shrub 8 ft. tall, 

 which blooms sparingly at various times during the 

 year: phyll. somewhat thick (flat when dried) and 

 succulent-looking, oblong-Unear, narrowed at base, 

 1J^2}2 '"• long, less than J^in. wide; 1 central nerve 

 ending in oblique point; gland below middle: fls. soh- 

 tary or in pairs, or occasionally in short racemes of 3-5 

 fls.; sepals united, truncate; petals 5: pod 1-2 in. long, 

 less than }<iin. broad, contracted between the seeds; 

 seed longitudinal; funicle scarlet its entire length, 

 folded several times at one end of seed; ripe .luiu^ 

 Sept. Fls. Feb.-May. — A neat little shrub with bright 

 green Ivs. The pods must be picked as soon as ripe and 



just before dehiscence, for the elastic opening of the 

 pod will discharge the seed in every direction. 



34. binervata, DC. (A. umbrbsa, Cunn.). Fig. 72. 

 Two-veined Hickory. A tall shrub or shrubby tree of 

 25 ft., with terete branchlets: phyll. falcate-lanceohite to 

 triangular, with 2 distinct veins (occasionally 3-veined) 

 and pinnately veined between, 2J'2-4 in. long, J-^-1 in. 

 wide; gland ]2^n. from base: fls. in racemes shorter than 

 phyll. ; peduncles J^in. long or more, 30 fls. in a head, 

 4- "or .5-merous; calyx not half so long as corolla: pods 

 straight, very thin, convex over seed, 4-5 in. long, li™- 

 wide; seed oblong; funicle long, nearly encircling seed 

 and bent back upon itself in double dark red fold, with 

 light aril at hilum end. B.M. .3.338. Maiden, Flowering 

 Plants of New S. Wales, pt. 5, p. 53. Wattles and 

 Wattlebarks, p. 50. — It inhabits dry, shaded woods in 

 the mountainous district of the coast. 



35. pendula, Cunn. Weeping Myall. A small tree 

 with gray fohage and pendulous branchlets: phyll. 

 covered with a minute pubescence, finely striate with 

 .3-5 obscurely parallel veins, linear-lanceolate, often 

 falcate, acuminate, ending in mu- 

 cronate point, 2-3 ^^ in. long, ].{- 

 }^in. wide; gland less than J^in. 

 from base: fl. -heads in pairs or 

 clusters, about 

 30 in a head; 

 peduncles less 

 than Yiin. long; 

 petals with mid- 

 rib ; sepals spatulate, retic- 

 ulately veined, half as long 

 as petals: pods liva. 

 broad, 2-3 in. long, bor- 

 dered by a narrow wing 

 along each suture. F. v. 

 M. Icon. 6:8.— The or- 

 namental value of this 

 species lies rather in 

 drooping fohage than in 

 the fls. 



36. melanoxylon, R. Br. 

 Blackwood Acacia. Fig. 

 72. A good - sized ever- 

 green tree of pyramidal 

 fonn and dense foliage: 

 phyll. oblanceolate to lan- 

 ceolate, usually one edge 

 straight, the other curved, 

 23^2"^/^ in. long (average 

 ZYz in. long by %m.. 

 wide),. 3-6 parallel nerves, 

 reticulately veined between; gland ](,vn. from base: fls. 

 cream-color, 40-50 in a head, with peduncles over }^in. 

 long, and in short racemes of 3-5 heads: pod reddish 

 brown, with ncrve-hke margins, more or less twisted 

 into shape of letter C or S, 3-5 in. long, ?8'n. wide; 

 seed longitudinal, J^in. in length, encircled in double 

 fold by a long red funicle which is very characteristic 

 of the species, the seed hanging on the trees thus for 

 months; pods ripe July-Nov. Us. late Feb. and 

 March. B.M. 1659. — Its wood is but little inferior to 

 black walnut for furniture - making and grillwork; it 

 makes a good street tree in Calif, and as a fuel it is 

 equal to hickory. 



37. implexa, Benth. Fig. 72. A tall tree, 50 ft. high, 

 with light green foUage and rough bark: phyll. falcate- 

 lanceolate, acuminate, with a more or less hooked 

 point, 4-7 in. long, ^j-S^in. wide, veins 3-5, with 

 finer parallel veins between ; no gland : fls. cream-yellow, 

 in racemes much shorter than phyll., 40-.50 in a head; 

 peduncles 5 gin. long: pod curved, often like an interro- 

 gation point, light brown with nerve-like margin, more 

 or less constricted and contracted between the seeds, 

 4-6 in. long, J^in. wide; seeds longitudinal; funicle 



73. Acacia salicina var. Wayae.
