ACACIA 



A( 'ACIA 



wide; very prominent gland, its position varying, some- 

 times above, sometimes below the middle: pod wider, 

 1 J-^-3 in. long, i^in. wide; funicle short (not surround- 

 ing the seed), filiform and ending in fleshy aril. Fls. 

 late Feb. and March. B.M. 3502. This variety does 

 not appear to seed in Calif. 



23. falcate, Willd. (A. plaffiophyUa, Spreng.). Tree 

 or tall shrub: phyli. distinctly pinniveined, lanceolate- 

 falcate, much narrowed toward base, 3-6 in. long; 

 nerve excentric; gland at base or none: racemes shorter 

 than phyll., 20 fls. in a head; sepals free, narrow, cUiate, 



about half as long 

 as petals; pet- 

 als striate, with 

 prominent m i d- 

 rib: pod flat, 2-3 

 in. long, ^iin. 

 wide; seed longi- 

 tudinal, close to 

 the margin; funi- 

 cle colored, ex- 

 tending around 

 seed and bent 

 back on itself in 

 a double fold, en- 

 larged at hilum 

 end into a fleshy 

 aril. This may 

 be distinguished 

 from A . penniner- 

 vis by its smaller 

 pod (half the size), 

 by its gland close 

 to base instead of 

 distant from it, 

 and by its free, 

 narrow, spatulate 

 ciliate sepals. 



24. penninervis, 

 Sieb. MOUNTAIN 

 HICKORY. A tall 

 glabrous shrub or 

 a tree, 40-80 ft. 

 high: phyll. pin- 

 niveined, lanceo- 

 late-falcate, acu- 

 minate, much 

 narrowed at the 

 base, 3-4 in. long 

 (sometimes twice 

 that length) about 

 3^in. broad; nerve 

 excentric with a 

 short secondary 

 nerve terminating 

 in a marginal 

 gland below the 



72. Acacia leaves. 1, A. longifolia; 2, middle: fls. pale 

 A. pravissima; 3, A. Cyclops; 4. A. bi- yellow, m short 

 nervata; 5, A. implexa; 6, A. pycnantha; 7, r-ircmr-^ innr-li 

 A. saligna 8, A. podalyriasfolia ; 9, A. mel- Ia ^ m f ' m " C 



anoiylon. (xH) shorter than 



phyll. ; peduncles 



l^in. long: pod 3J^~5 in. long, J^in. broad with nerve- 

 like margins; seed longitudinal; funicle colored, extend- 

 ing around seed and bent back on same side so as to 

 encircle in double fold. B.M. 2754. Maiden Wattles 

 and Wattlebark, p. 35. A variable species with very 

 narrow phyll., often J^-Hin. w 'de and 8-12 in. long, 

 the average being 1 in. broad and 5 in. long. 



Var. falcif6rmis, Benth. (A. falciformis, DC.). A 

 shrub 6-10 ft. high with young shoots and infl. 

 minutely hoary or golden pubescent: phyll. broad, 

 obliquely ovate-oblong, obtuse, smooth and feather- 

 veined, 34 in. long, 1 in. broad; gland at base: fls. in 

 racemes. Larger and more falcate than the type. 



25. pycnantha, Benth. (A.petiolaris,Lehm.). GOLDEN 

 WATTLE. BROAD-LEAVED WATTLE. Fig. 72. A small 

 tree with more or less pendulous branchlets: phyll. 

 pinniveined, oblong-lanceolate to falcate-lanceolate or 

 even broadly obovate, 2^-6 in. long, %-!} in. wide, 

 1 -nerved, the nerve more or less excentric; gland 

 VT-^A: in. from base: racemes either simple or com- 

 pound, large-fld., fragrant and showy, often bending 

 the tree with its weight of bloom; 50-60 fls. in a 

 head with peduncles J^in. long; sepals 5, ciliate, 

 almost as long as petals: pods varying, 2-4 l /2 or 5 in. 

 long, y^a\. wide, contracted and slightly constricted 

 between the seeds and with nerve-like margins; fu- 

 nicle whitish, club-shaped, not folded, half as long 

 as seed or occasionally folded and transverse to the 

 seed; ripe Aug. Fls. Feb., March. Maiden Wattles 

 and Wattlebark, p. 39. R.H. 1896, p. 504 Brown, 

 For. Flora of S. Austral. The name "broad-leaved" 

 is derived from its reference to the seedling Ivs., 

 which are of great size, sometimes 5 in. long and 

 4 in. wide. The bark contains the highest percent- 

 age of tannin of any of the species, but the tree does 

 not attain the size of A. decurrens, and hence so 

 great a quantity is not obtained from any one tree. 

 It is made into perfume, exudes a good gum, and is 

 used as a sand-binder. 



26. saligna, Wendl. (A. leiophylla, Benth.). Fig. 72. 

 A low tree or tall shrub with angular, rather drooping 

 branches: phyll. lanceolate to linear-lanceolate, or even 

 oblanceolate, 3-8]^ in. or lower Ivs. 1 ft. long, ]4,-\% or 

 even \% in. wide, acute to obtuse, narrowed to base; 

 1 central nerve, often excentric, ending in a recurved 

 point or obtuse; gland at base or none: fls. large (J^in. 

 in diam.), either in large racemes at the ends of the 

 branches or reduced to 4 or 5 heads strung along the 

 axils of the Ivs. for 2 or 3 ft. ; peduncles varying from 

 J^-J^in. in length: pods constricted between the seeds, 

 flat with nerve-like margins, 3-5 in. long, J^in. wide; 

 funicle club-shaped, three-fourths length of seed; ripe 

 Aug. Fls. March-May and to slight extent at various 

 times. Botanists do not find any well-marked differ- 

 ences between this species and the next and are there- 

 fore inclined to combine the two. Nurserymen base 

 their distinction on the color of the phyll., a bluish- 

 tinged one being called A. cyanophylla, while the green 

 phyll., especially if it is smaller, is called A. saligna. 

 Both forms are also said to have been secured from 

 seed gathered from a single tree. Nurserymen should 

 test this to satisfy themselves. Another so-called 

 botanical distinction gives the funicle straight in one 

 species and folded in the other. This does not hold, as 

 such a combination can be seen in the same plant, and 

 even in the same pod. This species is variable in other 

 respects. Fls. may be in groups of 4 or 5 and strung 

 along the axis of Ivs. for 2 or 3 ft. This type may have 

 either large or small or even mixed phyll., or the fls. may 

 be in large clusters (either erect or pendulous) at the 

 ends of the branches. In either case, the large or the 

 small or the mixed types of phyll. may accompany 

 them. 



27. cyanophylla, Lindl. BLUE-LEAVED WATTLE. 

 Tall shrub, 18 ft., stolonif erous : branches drooping: 

 lower phyll. about 12 in. long; upper 6 in. or less and 

 narrower, linear-oblong to lanceolate-falcate, much 

 narrowed toward the base, glabrous and often glaucous: 

 peduncles J^-J^in. long; fls. 3-5, large, golden yellow. 

 March. Gn. 52, p. 99. Said to be the same as A. 

 saligna, as they run into each other. 



28. obtusata, Sieb. Tall, glabrous shrub: phyll. 

 lJ^-3 in. long, oblong-linear, or almost spatulate, 

 usually almost straight, rather obtuse, point not curved, 

 thick, rigid, with thickened, nerve-like margins; mar- 

 ginal gland 1, distant from the base, not prominent: 

 racemes about. %in. long, with densely packed heads; 

 fls. 30 or more. March.
