* vlridlflora (greenish-flowered).* fl. green, spot 

 scape many-spiked, many-flowered. May and Jui 

 ensftorm, edged, h. 1ft. 1780. (B. M. 549, un 



jtted at base; 

 June. I. linear- 



oiiouuii.i, odged. h. 1ft. 1780. (B. M. 549, under name of 

 /. maculata viridis.) There are two varieties : cana (B. M. 789, 

 under name of /. maculata amethystina) and ca'sia (A. B. B. 

 530, under name of 7. maculata ccesia). 



IXIOLIRION (from Ixia, and Leirion, a Lily ; Ixia- 

 like Lily). STN. Kolpakowskia. ORD. Amaryllidece. A 

 genus of two species of elegant half-hardy bulbous plants, 

 with loose racemes of large trumpet-shaped flowers, and 

 narrow, grass-like leaves. Probably the two species here 

 mentioned are simply forms of one. They thrive best 

 in an open, dry, sunny, and well-drained border, and 

 the most suitable soil is a light loamy one. If culti- 

 vated outside, the protection of a handlight is needful, 

 when commencing growth, in spring. The bulbs may be 

 carefully lifted in the autumn, and stored away in a 

 dry place. 



I. Kolpakowskianum (Kolpakowski's). fl. bine or white ; 

 perianth trumpet-shaped, with a long, slender tube, and six 

 narrow-acute segments. Summer. I. linear, h. 1ft. Lake Sairan, 

 1878. SYN. Kolpakowskia ixiolirioides. (R. G. 953.) 

 I. montanum (mountain). A synonym of /. tataricum. 

 I. Pallasi (Pallas's). A synonym of /. tataricum brachyantherum. 

 I. tataricum (Tartar), fl. blue ; segments more or less spread- 

 ing or recurved ; inflorescence sometimes paniculate. June. 

 I. broadly linear, h. 1ft. to lift. Central Asia, &c., 1844. SYN. 

 /. montanum. (B. R. 1844, 66.)

 (R. G. 910.) 



1. 1. Ledebourii (Ledebour's). This differs from the type prin- 

 cipally in the curvature of the anthers after flowering. Central 

 Asia, 1880. (R. G. 1014.) 



IXODIA (from ixodes, viscid ; in reference to the 

 viscid secretions on the plant). ORD. Composites. A 

 monotypic genus. The species is a glabrous greenhouse 

 evergreen shrub, from Australia. It thrives in a com- 

 post of sandy peat and a little fibry loam. Propagated 

 in May, by cuttings of the young shoots, getting hard 

 at their base, inserted in sand, under a bell glass, in a 

 close frame or pit. 



I. achilleoides (Achillea-like). fl.-heads in a dense terminal 

 corymb, very much resembling those of Achillea, the white, petal- 

 like, radiating laminae of the inner involucral bracts being similar 

 to the ray-florets of that genus ; involucre glutinous, with green 

 centres, and often slightly woolly. June. I. linear-lanceolate or 

 slightly spathulate, usually acute, mostly above lin. long, more 

 or less decurrent on the stem. h. lift. 1803. (B. M. 1534.) 



XXORA (the name of a Malabar idol, to which the 

 flowers of some of the species are offered). SYNS. Sidero- 

 dendron, Sideroxyloides. ORD. Rubiacece. A genus 

 comprising about 100 species of stove evergreen shrubs 



Ixora continued. 



or small trees, natives, for the most part, of the tropical 

 regions of Asia and Africa, and rarely of America, 

 Australia, and the Islands of the Pacific. Flowers 

 scarlet, pink, or white, handsome, in terminal corymbs ; 

 corolla salver-shaped; tube long, slender. Leaves oppo- 

 site, rarely ternate, verticillate, coriaceous, petiolate or 

 sessile. Ixoras are amongst the most handsome and 

 gorgeous of stove flowering plants. They are usually of 

 a compact bushy habit, requiring but little training, and 

 the foliage itself is by no means unattractive. Pro- 

 pagation is readily effected by cuttings : these should 

 be short-jointed, and moderately firm, and be inserted 

 singly in small pots, which should afterwards be plunged, 

 in a close frame, with a bottom heat of about SOdeg., 

 and kept shaded. Roots will, as a rule, soon be emitted ; 

 the plants* may then be inured to the open house, 

 and placed in Sin. pots. If kept in a high temperature, 

 and supplied with plenty of moisture, they soon grow. 

 Some of the species and hybrids flower in this size, 

 and are very attractive. A compost of fibry peat, a 

 little leaf soil, and plenty of silver sand, is most 

 suitable for Ixoras at all stages of their growth. It 

 should be made rather fine for cuttings, and used in a 

 rough state for established plants. Almost any amount of 

 heat and moisture may be applied to these subjects in 

 summer; but a cooler and somewhat drier atmosphere 

 should be maintained in autumn and winter, for ripening 

 the wood. Young plants succeed and grow freely, if 

 plunged in a bed of fermenting material ; but this 

 should not be allowed to become very hot. A little 

 shade from bright sunshine is advisable in summer 

 time; but in dull weather, and at other seasons, all 

 possible light should be admitted.
