ORIXA (Japanese name). Rutacese. Deciduous 

 shrub, with alternate petioled almost entire Ivs., and 

 greenish inconspicuous dioecious fls. with 4 sepals and 

 4 minute petals, the staminate fls. in racemes, the pis- 

 tillate fls. solitary: fr. 

 consisting of 4 dehiscent 

 pods, each containing 1 

 black subglobose seed. 

 It has proved hardy in 

 Mass., but has no dec- 

 orative merit except its 

 bright green foliage, 

 which is not attacked by 

 bisects or fungi, and has 

 a strong disagreeable 

 odor like that of ptelea. 

 Orixa seems to grow in 

 almost any soil. Prop, 

 by greenwood cuttings; 

 also by layers and root- 

 cuttings and by seeds. 

 The only species is O. 

 jap6nica, Thunb. (Celds- 

 trus Orixa, Sieb. & Zucc. 

 Ilex Orixa, Spreng. 

 Othera Orixa, Lam.). 

 Fig. 2677. Shrub, to 8 ft., 

 with spreading branches 

 pubescent when young: 

 Ivs. obovate to oblong, 

 obtusely pointed, entire 

 or finely crenulate, bright 

 green above, finely pu- 

 bescent beneath, trans- 

 lucently glandular-punc- 

 tate, 2-A in. long: fls. 

 small, greenish: pods 

 about 3^ m - l n g> light 

 greenish brown. April,

 seeds of some species used as beads). Leguminbsse. 

 NECKLACE TREE. Trees, around the world in the 

 tropics, of 40 or more species, bearing large panicles or 

 racemes of white, lilac or black-purple papilionaceous 

 fls., and often handsomely colored seeds, planted some- 

 times in warm countries: calyx more or less 2-lobed, the 

 2 upper teeth being somewhat connate; standard very 

 broad, the wings obovate-oblong and oblique; stamens 

 free and unequal ; stigma lateral : pod leathery, woody, or 

 fleshy, oblong to linear and compressed, wingless and 

 2-valved, sometimes septate: Ivs. odd-pinnate, with 

 coriaceous Ifts. 



monosperma, Urban (Sophora monosperma, Swartz. 

 Ormosia das year pa, Jacks.). Fig. 2678. Offered abroad : 

 large tree: Ifts. 5 pairs, oblong and pointed, 3-4 in. long: 

 fls. blue, %in. long in large rusty panicles: pod 13^ in. 

 long, tomentose, 1 -seeded; seed somewhat compressed, 

 irregular in shape, Hin. or more longest way, bright 

 scarlet with large angular black patch. W. Indies. 



Other species do not appear in accessible lists, but they may be 

 sparingly in cult. O. coccinea, Jacks., of S. Amer., is in horticultural 

 literature: Ifts. ovate, the margins revolute: fls. blue: pod glabrous 

 and shining; seeds scarlet, with black spot. L H B 



ORNAMENTAL GARDENING, or ornamental 

 horticulture, is that branch of horticulture concerned 

 with cultivating plants of all kinds for show and to 

 satisfy the eye rather than for food. It includes flori- 

 culture and also the culture of trees for shade and dis- 

 play. (The culture of trees on a large scale for -timber 

 and for other profitable purposes aside from ornament 

 is forestry. The culture of trees in general is arbori- 

 culture.) Ornamental gardening includes carpet-bed- 

 ding and formal gardening in general, while landscape

gardening is concerned with making nature-like pic- 

 tures, or at least with the general plan and setting of 

 the place; it also comprises all that part of floriculture 

 that aims to make grounds and gardens beautiful. 



ORNITHLDIUM (the diminutive for bird, from the 

 form of the flower). Orchidacese. Epiphytic orchids 

 for the warm greenhouse. 



Stems leafy, covered with distichously imbricated 

 sheaths, the 1-lvd. pseudobulbs lateral: fls. medium or 

 small, solitary on peduncles which are fascicled in the 

 axils; sepals and petals similar, the sepals free, a little 

 larger than petals; lip 3-lobed, the lateral lobes erect, 

 sometimes inclosing the column; column usually short 

 and footless; pollinia 4, waxy. About 20 species, in 

 Trop. Amer. 



densum, Reichb. f. (Maxillaria densa, Lindl.). 

 Pseudobulbs oblong, compressed: peduncles densely 

 fascicled; sepals and petals yellowish, the column and 

 lip marked with rose. Mex. B.R. 1804. 



fragrans, Rolfe. Pseudobulbs ovoid-oblong: fls. few, 

 fragrant, white, faintly flushed with mauve; sepals 

 spreading, oblong-linear, rather acute, the petals some- 

 what connivent, lanceolate-linear, acute; lip 3-lobed, 

 dull mauve, the lateral lobes small, the middle lobe 

 reflexed, quadrate-oblong, truncate or emarginate.

ORNITHOCEPHALUS (Greek, bird and head in 

 allusion to the aspect of the column). Orchidacese.

 free, spreading; upper sepal concave; labellum subsessile, 

 3-lobed, lateral lobes broad and thickened, middle lobe 

 elongated; column short with the rostellum conspicu- 

 ously elongated; pollinia 4. About 20 species from 

 Brazil to W- Indies and Mex. The geographical range 

 of the species herein described indicates an intermedi- 

 ate temperature. They may be treated like cattleyas. 



grandiflorus, Lindl. A dwarf compact epiphyte: Ivs. 

 distichous, oblong, obtuse, about %in. long: scape from 

 the axil of the Ivs.; fls. small, whitish, about 

 across, borne in racemes;

 emerald-green; labellum 

 3-lobed, somewhat 

 rounded, saccate, keeled 

 beneath. Brazil. 



multiflfirus, Rolfe. 

 Plant densely cespitose: 

 sts. 2% in. high, diphyl- 

 lous: Ivs. lanceolate or 

 oblong, somewhat fleshy,
