IXIOLIRION (Greek, an ixia-like lily). Amaryl- 

 lidacese. Three or four species of hardy bulbs from 

 western and central Asia, with umbels of deep blue or 

 violet six-lobed flowers, borne in spring. 



Perianth regular, without tube above the ovary; 

 segms., oblanceolate, acute; stamens shorter than the 

 segms., attached to their claws; ovary club-shaped, 

 3-celled, becoming a 3-valved caps.: Ivs. very narrow, 

 mostly at base of the st. The nearest cult, allies are 

 Alstroemeria and Bomarea, which have no distinct 

 rootstock, while Ixiolirion has a bulbous rootstock. 

 The bulbs should be lifted in autumn and stored. 



montanum, Herb. (7. Pdllasii, Fisch. & Mey.). Bulb 

 ovoid, 1 in. thick, with a neck 2-3 in. below the basal 

 tuft of Ivs.: st. about 1 ft. long: Ivs. about 4, persistent, 

 and a few smaller ones above: fls. on long unequal 

 pedicels, about 4, and often 1 or 2 fls. below; perianth 

 bright lilac according to Baker, 1 ^ in. or less long. 

 Syria to Siberia. B.R. 30:66. F.S. 22:2270. RH 

 1880:310. J.H. III. 31:583. 



Var. tataricum, Herb. (7. tatdricum, Hort. 7. 

 Ledebourii, Fisch. & Mey.). Sts. more slender: Ivs. 

 awl-shaped: fls. all in a terminal umbel, smaller than 

 the type. Altai Mts. G.C. II. 19:757. Gn. 75, p. 188. 

 Gn.W. 21:685. J.H. III. 42:532. 



I. Kolpakowskianum, Regel (Kolpakowskia ixiolirioides, Regel), 

 is perhaps a form of above, but has a smaller bulb, fls. 2-4 in a 

 terminal umbel, and the perianth-segms. %-l in. long: Ivs. about 4 

 in a basal tuft and 1 or 2 small ones above. Turkestan. Gt.

IXORA (a Malabar deity). Rubiacese. Warmhouse 

 woody plants with showy flowers in clusters and ever- 

 green foliage; handsome and desirable. 



Shrubs or small trees with opposite or verticillate 

 Ivs. and terminal or axillary usually dense corymbs of 

 very showy white, rose or scarlet fls. on bracteate 

 pedicels: corolla very long and slender -tubed, the 

 throat sometimes barbed, the limb 4- or 5-lobed and 

 wide-spreading; stamens 4 or 5, inserted on the throat, 

 the filaments short or none; ovary on a fleshy disk, 

 2-loculed, the style filiform and exserted, 2-branched; 

 ovules solitary: fr. a hard or fleshy 2-pyrenous berry. 

 Species upward of 150, in the tropical parts well around 

 the globe. 



There are many garden forms of Ixora under Latin 

 names, and these complicate a botanical account of the 

 genus. Some of the named garden ixoras are the follow- 

 ing: Amabilis, pinkish, suffused orange. Aurantiaca, 

 orange-red; compact. Chelsonii, fls. brilliant salmon- 

 orange. Colei, fls. pure white: cross of 7. coccinea and 

 7. stricta var. alba. Conspicua, fls. yellow, becoming 

 orange. Decora, yellow. Dixiana, fls. deep orange; 

 G. 27:363. F. S. R. 3, p. 275. Fraseri, fls. scarlet in the 

 tube, and brilliant salmon above; G. 7:529. Illustris, 

 orange. Incarnata, flesh-color. Insignis, rose. Ornata, 

 salmon-orange. Pilgrimii, orange-scarlet. Princeps, fls. 

 whitish, becoming orange; said to have come from 

 Java. Profusa, rose. Regina, fls. shaded violet-salmon, 

 in large dense clusters. J.H. III. 42:159. Sanguinea, 

 fls. crimson, shaded with violet. Speciosa, yellow. 

 Splendens, orange. G.Z. 23:193. Splendida, crimson- 

 orange. G.Z. 26, p. 217. I.H. 29:463. Venusta, orange. 

 Westii, fls. pale rose, becoming brilliant; hybrid. Gn. 

 42:496. G.M. 36:35. G. 25:457. Williamsii, fls. 

 reddish salmon. 



The ixoras are perhaps the best tropical warmhouse 

 plants that combine the showiest of flowers with fine 

 evergreen foliage. They are of easy culture, and should 

 be far oftener seen in tropical plant-houses. They 

 may be propagated at any season, but early spring is 

 probably best. Take good strong cuttings, with four
