IXIOLlEION (Greek, nn Ixia-Uke lily). AmarylliM- 

 ce<e. 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 al)0ve the ovary; segments oblanceo- 

 late; stamens shorter than the segments, attached to 

 their claws. The nearest cultivated allies are Alstroe- 

 meria and Bomarea, which have no distinct rootstock, 

 while Ixiolirion has a bulbous rootstock. Monogr. by 

 Baker, Amaryllidenj, 1888.

IXdRA (a Malabar deity). Subidcete. 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 arc 

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

IXORA 



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 

 flesliy disk, 2-Ioculeil, 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 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, afff-r bavir.' fini-ilied their growth in the early 



autumn, tli. - i I i"' ; i ir,.(l for a time into a lower or 



greenhouvr I i n which they would more fully 



ripen tliiir . ml set and develop their flower 



buds. Ail' r Tin-, ,!,. h :i_-ain placed in the warmhouse, 

 the plants will keep llowc-ring 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 takennottooverpot 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 

 00° while growing. They propagate freely from cuttings 

 of half-rine 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. 



Many of the Latin names of Ixoras are of horticultural 

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

 pure white: cross of /. coccijica and /. s/Wc^o,var. a/6a. 

 Connpiciia, fls. yellow, becoming orange. Dixidna, fls. 

 deep orange. Frdseri, fls. scarlet in the tube, and bril- 

 liant salmon above. Ortidta, salmon-orange. Prlncepa, 

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

 Java. BegXna, fls. shaded violet-salmon. Sanguinea, 

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