IXIOLlRION (Greek, a« Txia-like lily). Ainaryllid,}- 

 ce<p. A genus of 2 species of hardy bulbs from western 

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

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

 without any tube above the ovary; segments oblauceo- 

 late; stamens shorter than the segments, attached t<) 

 their claws. The nearest cultivated allies are Alstni-- 

 meria and. Bomarea, which have no distinct rootstock, 

 ■while Ixiolirion has a bulbous rootstock. Monogr. by 

 Baker, Amaryllideai, 1888.

IXORA (a Malabar deity). J^)<bi().cecr. Many species 

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

 verticillate Ivs. and terminal or axillary corymbs of A'ery 

 showy fls., inhabiting the tropical parts of Asia, Afri<'a, 

 America, Aiistralia and Pacific islands. The species arc 

 very difficult to distinguisli. The Hs. 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-locuIed, the style filiform and exserted, 2- 

 brauched: ovules solitary. L. H. B. 



Ixoras, which are handsome dwarf flowering shrubs, 

 belong to the tropics. The species, as w^ell 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 flnished their growth in the early 

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

 i^reeuhouse temperature, in which they would more fully 

 ripen their young growth and set and develop their flower 

 i)uds. 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 takennot tooverjiot tbem. 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 

 ()0° while growing. They propagate freely from cuttings 

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

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

 with liquid manure will bring out the size and color of 

 the flowers to perfection. H. A. Siebrecht.
