ARAUCARIA 



ARAUCARIA 



302. Araucaria excelsa, a poor speci- 

 men because too crowded or not suffi- 

 cient light. 



F.S. 22: 2304-2305. An excellent house plant, and 

 keeps well in a cool room near a window. In summer 

 it may be used on the veranda, but must be shaded. 



The timber is used 

 for ship-building. 



2. Cunninghamii, 

 Sweet. Plants less 

 formal and sym- 

 metrical than A . 

 excelsa, the upper 

 branches ascend- 

 ing and the lower 

 horizontal: Ivs. 

 stiff and very 

 sharp-pointed, 

 straight or nearly 

 so. There is also a 

 glaucous form (A, 

 glauca) ; also a 

 weeping form. 

 Austral., where it 

 reaches a height 

 of 200 ft., yielding 

 valuable timber 

 and resin. Locally known as hoop pine, Moreton Bay 

 pine, colonial pine, coorong, cumburtu, coonam. 



3. Codkii, R. Br. (A. columnaris, Hook.). A slender 

 columnar tree, much narrower in shape than A. excelsa 

 which it closely resembles when young: branches dis- 

 posed as in A. excelsa, but tree tending to shed the 

 lower ones; branchlets crowded on the branches and 

 turning upwards in a boat-like form: young Ivs. 

 alternate and rather closely arranged on the branchlet 

 and J^in. long, broad 



and slightly decurrent 

 at base, slightly curved, 

 mucronate; adult Ivs. 

 densely imbricated, _j^ 

 short and ovate, ob- 

 tuse; cones 3-4 in. 



diam. and somewhat 303. Araucaria excelsa. ( x M) 

 longer. New Cale- 

 donia, where it reaches a height of 200 ft., making 

 very straight and imposing shafts. B.M. 4635. A.F. 

 12:559. Named for Captain Cook. Var. a urea, Hort., 

 has golden-yellow foliage. There is also a var. glauca, 

 Hort., with silvery Ivs. 



4. Balansae, Brongn. & Gris. (A. elegans, Hort. 

 Bull.). A dwarf-growing species of slow growth (when 

 grown as a pot-plant) and with few loosely arranged 

 tiers of branches, usually 5 in a tier; branchlets 

 distichous, narrow and deflexed with age: Ivs. imbri- 

 cated, short, stiff; Y%m. long, falcate, more or less 

 obtuse, dark olive-green in color: male cones cylindri- 

 cal-conical, 2-3 in. long; female cones globose or 

 elliptic, 4 in. long. New Caledonia. Rarely grown. 

 The narrowest and most slender-branched species 

 in cult. 



AA. Lvs. broader, usually plane and imbricated. 



5. Riilei, Muell. Fig. 304. Leafy branchlets very 

 long: Ivs. oval-elliptic, imbricated, concave, arched 

 towards the branch, nearly or quite obtuse, with a 



prominent dor- 

 sal nerve, sil- 

 very gray on 

 the upper and 



304. Araucaria Rulei. ( X M) 



rich glossy 

 green on the 

 lower side. Variable at -different ages. When young, 

 the branches are often drooping and the Ivs. com- 

 pressed and obscurely 4-angled and nearly or quite 

 subulate, var. polymdrpha, R.H. 1866, p. 350. There 

 is also a var. compacta. New Caledonia. Reaching 50 

 ft. in height. R.H. 1866:390, and plate. I.H. 



305. Araucaria 

 Bidwillii. (XH) 



22:204. A strikingly beautiful plant and somewhat 

 rare in cult. The figure in G.C. 1861:868, is A. 

 Mitelleri, Brongn. & Gris., a broader-lvd. species. 

 Var Goldieana, Hort. (.4. Gohlieana, T. Moore). A 

 variety with narrower Ivs. and with branches rather 

 more erect than the type. F. 1877:39. A var. elegans, 

 Hort., is described ,with smaller Ivs., and close-whorled 

 more slender branches: 

 dwarf. | 



6. Bidwillii, Hook: 

 Fig. 305. Rather nar- 

 row in growth, especi- 

 ally with age, the 

 branches simple: Ivs. 

 in two rows, lance- 

 ovate and very sharp- 

 pointed, thick, firm 

 and shining. Austral., 

 where it attains a 

 height of 150 ft., and 



is known as bunya-bunya. R.H. 1897, p. 500, desc. G.C. 

 III. 15:465, showing the pineapple-like cone. One of 

 the best and handsomest species for pots. 



7. braziliana, A. Rich. (A. grdcilis, Hort.). Branches 

 verticillate, somewhat inclined, raised at the ends, 

 tending to disappear below as the plant grows: Ivs. 

 alternate, oblong-lanceolate, 1-2 in. long, somewhat 

 decurrent, much attenuated and very sharp-pointed, 

 deep glaucous green, loosely imbricated: cone large and 

 nearly globular. S. Brazil, reaching a height of 100 ft. 

 F.S. 21:2202. Var. elegans (A. elegans, Hort.), is a 

 form with very numerous branches and more crowded 

 and often glaucous Ivs. Var. Ridolfiana, Gord., is a 

 more robust form, with larger and longer Ivs. 



8. imbricata, Pav. MONKEY PUZZLE. Figs. 306, 307. 

 A striking tree of pyramidal habit: branches generally 

 in 5's, at first horizontal, with upward-curving (some- 

 times downward-curving) tips, but finally becoming 

 much deflexed; branchlets in opposite pairs, curved 

 upward when young, and continuing to grow until 

 several feet long when adult: Ivs. imbricated and per- 

 sisting, even on the trunk, ovate-lanceolate, very stiff, 

 leathery, and sharp-pointed, 2 in. long on the primary 

 st. and branches, 1 in. long on the branchlets, slightly 

 concave at the base, bright green on both sides: cone 

 6-8in.diam. West- 

 ern slope of the An- 

 des in Chile, reach- 

 ing a height of 100 



ft. F.S. 15: 1577- 

 1580. R.H. 1893, 

 p. 153; 1897, pp. 

 271, 319, desc. Gt. 

 44:115. G.C. III. 

 21:288; 24:154. 

 Hardy in the S. 

 This is the species 

 which is grown in 

 the open in Eng- 

 land and Ireland. 

 The hardiest species 

 in cult. Thrives well 

 in a heavy loamy 

 soil in a moist valley 

 or position shel- 

 tered from rough 

 winds in mild clim- 

 ates. The branches 

 are heavy and 

 rather brittle and 

 the beauty and 

 symmetry is soon 



destroyed if planted ,.-,--- - 



in an exposed posi- 

 tion. The timber is 306. Araucaria imbricata. California.
