IXIOLtKION (Greek, an Ixia-like lily). Amaryllidd- 

 cece. A genus of 2 species of hardy bulbs from western 

 Asia, with umbels of 5-9 deep blue or violet, 6-lobed 

 fls. each 2 in. across, borne in spring. Perianth regular, 

 without any tube above the ovary; segments oblanceo- 

 late; stamens shorter than the segments, attached to 

 their claws. The nearest cultivated allies are Alstrce- 

 meria and Bomarea, which have no distinct rootstock, 

 while Ixiolirion has a bulbous rootstock. Monogr. by 

 Baker, Amaryllideffi, 1888. 



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

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

 tuft of Ivs.: stem about 1 ft. long: Ivs. about 4, 

 persistent, and a few smaller ones above: fls. on long 

 unequal pedicels and often 1 or 2 fls. below; perianth 

 bright lilac according to Baker. Syria to Siberia. B.R.

 more slender: Ivs. awl-shaped: fls. all in a terminal 

 umbel, smaller than the type. AltaiMts. G.C. II. 19:757. 

 Regel calls the collective species 7. Tataricum, and de- 

 . scribes 5 species of it. 



IXORA (a Malabar deity). Rubiacece. Many species 

 (100 or more) of shrubs or small trees with opposite or 

 verticillate Ivs. and terminal or axillary corymbs of very 

 showy fls., inhabiting the tropical parts of Asia, Africa, 

 America, Australia and Pacific islands. The species are 

 very difficult to distinguish. The fls. are white, rose or 

 .scarlet, 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. L. H. B 



Ixoras, which are handsome dwarf flowering shrubs, 

 belong to the tropics. The species, as well as their hy- 

 brids, all bear beautiful trusses of flowers of various 

 shades, from a creamy white to a rich crimson. They 

 require a stove temperature during most of the time 

 although, after having finished their growth in the early 

 autumn, they could be placed for a time into a lower or 

 greenhouse temperature, in which they would more fully 

 ripen their young growth and set and develop their flower 

 buds. After this, when again placed in the warmhouse, 

 the plants will keep flowering until spring. .Sandy leaf- 

 mold, with plenty of drainage, is best to cultivate them 

 in. They like plenty of heat and moisture, and care 

 should be taken not to overpot them. The foliage should 

 be syringed often, as otherwise the mealy bug and other 

 insects will infest them. They do best in a sunny spot 

 in a greenhouse temperature, but should not fall below 

 60 while growing. They propagate freely from cuttii 

 of half-ripe wood, and they produce their best Howe 

 when the pots are filled with roots; then a little feedi 

 with liquid manure will bring out the size and colon 

 the flowers to perfection. H. A. SIEBRECHT. 



Many of the Latin names of Ixoras are of horticulti 

 forms. Of this class, the following are in the Ame 

 trade: Chelsoni, fls. brilliant salmon-orange. Cdlei, 

 pure white : cross of J. coccinea and 7. s1ricta,vs.r. all 

 Conspicua, fls. yellow, becoming orange. Dixidna, 

 deep orange. Fraseri, fls. scarlet in the tube, and 

 liant salmon above. Ornata, salmon-orange. Prince} 

 fls. whitish, becoming orange; said to have come fr 

 Java. JZeglna, fls. shaded violet-salmon. Sanguined, 

 fls. crimson, shaded with violet. Splendida, crimson- 

 orange. I.H. 29:463. Westii, fls. pale rose, becoming 

 brilliant; hybrid (Gn. 42:886. G.M. 36:35). Williamsii, 

 fls. reddish salmon. Other horticultural forms are: 

 Armeniaca, yellow; Decora, yellow; Illustris, oranj 

 Insignis, rose ; Pilgrimi, orange-scarlet ; Profusa, 

 Specidsa, -yellow; Splendens, orange; Venusta, orar 



A. Fls. usually in shades of red (sometimes varying 

 rose). 



stricta, Roxbg. (/. coccinea, Hort. /. bldnda, 

 I. crocdta, Lindl.). . Apparently the common sj 

 known in greenhouses as 7. coccinea: glabrous shrul 

 with sessile or subsessile Ivs. which are obovate or obo- 

 vate oblong,and very slender-tubed fls. in dense corynit 

 the corolla lobes short and rounded. Moluccas 

 China. B.M. 169 (as /. coccinea). B.R. 10:782. -R-. 

 into nearly pure white forms. /. striata of the import* 

 of Japanese plants is probably a misprint for strict 

 There are said to be yellowish fld. forms. Prince 

 Orange is said to be a form of this species. 



coccinea, Linn. (J. grandiflbra, Br. 7. Bandhi 

 Roxbg. ) . Much like the last, but Ivs. oblong and corol 

 lobes acute. E.Indies. B.R. 2:154; 6:513. 



macrothyrsa, Tejsm. & Binn. (7. Duffii, Moore). 

 Very large, glabrous: Ivs. a foot long, linear-oblong to 

 oblong-lanceolate : cluster very large, 8 in. across, 

 bearing very many deep red tinged crimson fls., with 

 lanceolate obtuse lobes about % in. long. E. Indies. B. 

 M. 6853. Probably the finest of the germs. 



AA. Fls. in shades of yellow or orange. 



Javanica, DC. Glabrous shrub with Ivs. 5-7 in. Ion?, 

 ovate-oblong, acute or acuminate: corymb terminal, with 

 forking coral-red branches: fls. deep orange-red, the 

 lobes rounded. Java. B.M. 4586. 



congesta, Roxb. (7. Griffithii, Hook.). Evergreen 

 tree in its native haunts, glabrous, except the cyiues: 

 Ivs. very large (6-12 in. long), stalked, elliptic or elliptic- 

 oblong, acute or acuminate: cymes sessile or nearly so: 

 fls. orange-yellow, changing to reddish, the segments 

 rounded. Indies. B.M. 4325. 



AAA. Flowers white. 



parviflora, Vahl. Evergreen tree, with subsessile ob- 

 long or elliptic-obtuse Ivs. 3-6 in. long: cymes sessil< 

 fls. white, the tube only % in. long. India. L. H. B.
