HENDERSON'S HANDBOOK OF PLANTS. 



IVY 



cuttings of the young wood. Introduced in 

 1838. 



Ivy. See Hedera. 



Lxia. From ixia, bird lime; in reference to the 

 clammy juice. Linn. Triantlrin-Monogynut. Nat. 

 Ord. Iridacete. 



A genus of beautiful Cape bulbs, with narrow 

 ensate leaves, and slender, simple, or slightly 

 branched stems, bearing spikes of large showy 

 flowers, various in color, and exceedingly attract- 

 ive when fully expanded by sunshine. These 

 flowers have a salver-shaped perianth, with a 

 slender tube, and six-parted, spreading, equal 

 limb, three stamens inserted in the throat, with 

 filiform filaments and versatile anthers, and a 

 three-celled ovary with numerous ovules, termi- 

 nating in a filiform style, and three narrow 

 linear conduplicate recurved stigmas. /. viridi- 

 flara, which has large sea-green flowers with 

 black markings at the base of the segments, is a 

 very singular-looking, as well as very beautiful 

 plant There are many species and some varie- 

 ties, and the greater part of them are worthy of 

 cultivation. They are half hardy, but with us 

 should be grown in pots in the green-house; 

 about midwinter they will begin to show their 

 handsome flowers freely. When done flowering 

 they should be dried off till September or Octo- 

 ber, which is the proper time to start them 

 again. They grow well in a light loam with 

 the addition of leaf mould and sand. Propa- 

 gated by offsets. First introduced in 1757. 



Ixiolirion. From ixia, and leirion, a lily; literally, 

 Ixia-like Lily. Linn. Hexandria-Monogynia. Nat. 

 Ord. AmaryUidtic.fd'. 



A small genus of rare and beautiful little 

 hardy bulbs from Asia Minor. They have 

 simple erect stems, with terminal clusters or 

 racemes of sky-blue flowers. Propagated by 

 seeds or offsets. Introduced in 1844. 



Ixora. Named after Isvara, a Malabar deity, to 

 whom the flowers of some are offered. Linn. 

 TetrandriO'Mmogynia. Nat. Ord. Cinchonaceo'. 



JAS 



A genus of Indian and tropical African shrubs, 

 with corymbs of handsome flowers of a scarlet, 

 pink, or white color, and frequently having an 

 agreeable fragrance. The history of Ixora coc.- 

 rinea, the best known species, is rather curious. 

 It is a native of China and some of the East 

 India islands, where it is worshiped as a sacred 

 plant, and where it is said to form a small tree 

 about six feet high, rising with a single stem, 

 and having its head formed entirely of clusters 

 of bright scarlet and yellow flowers, whence it 

 has received the name of flamma Sylrarum, or 

 the Tree of Fire. This plant was first intro- 

 duced in 1690; but it was soon lost, and its ex- 

 istence was even doubted till it was re-intro- 

 duced about a hundred years afterward by the 

 celebrated Dr. Fothergill. The Ixoras are really 

 magnificent plants, and should be grown in a 

 warm temperature. They are propagated from 

 cuttings, and should be grown in a sandy loam 

 and leaf mould. When re-potted, which should 

 be done immediately after flowering, the plants 

 will be benefited by being plunged into a mode- 

 rate bottom heat, which induces them to root 

 freely, and to form the growth quickly and with 

 vigor, thus enabling them to become properly 

 ripened before winter. In the spring, when the 

 flower heads begin to appear, a liberal regimen 

 should be adopted, and liquid manure occa- 

 sionally applied. At this time, and, indeed, 

 throughout the summer, the foliage should be 

 frequently syringed, in order to keep it clear of 

 insects, and to preserve its rich green and glossi- 

 ness. As soon as the flowers are expanded, and 

 onward till the growth is complete, the plants 

 should be shaded from powerful light, and 

 through the summer a moderately moist atmos- 

 phere of about 75 should be kept about them. 

 In winter the ordinary attention required by 

 hot-house plants will suffice. The taste for hard- 

 wooded plants is on the increase. Among the 

 best is the Ixora, which should be more gener- 

 ally grown.
