Glabrous, the corymbs puberulous and recurved ; berries crowned by the calyx-lobcs, 



. . I. recurva. 

 Glabrous, also the erect or nearly erect corymbs ; berries marked by the circular scar 



of the fallen calyx-limb, /. webercefolia. 



O Corolla-tube slender, ^ — | in. long ; flowers pedicelled. 



All parts (also the corymbs) glabrous, in drying remaining green, /. Pavetta. 



All parts more or less puberulous to tomcntose, usually tm-ning black in drying ; 



corymbs short-puberulous, /. tomentosa. 



All parts villous-puboscent, in drying not blackening ; corymbs villous from spreading 



short hairs, 7. naudeiflora. 



Sithg. 2. Ixora. L. Flowers 4- rarely 5-merous. Style shorter or 

 longer exserted but never exceeding the corolla-tube by more than \ — f of 

 its length, the stigmatic lobes usually spreading, rarely longer cohering. 

 §. Eu-Ixora. Flowers 4-merous. 



* Flotvers in sessile or peduncled cymes or corymbs. 



X Corymbs trichotomous, short-peduncled or sessile and in this case con- 

 sisting of 3 or more terminal peduncled cymes. Flowers and fruits 

 conspicuously (1 — 21in.) pedicelled as in true Pavetta. 

 -f Leaves acuminate or acute at the base, on a petiole | — 1 in. long. 

 Leaves one-coloured, black in drying ; flowers white ; corolla-tube 4 lin. only long, 



. . /. coriacea. 



Exactly as preceding, but corolla-tube nearly an inch long, /. macrosiphon. 



Leaves pale-coloured beneath ; flowers pale-rose ; corolla-tube an inch long, I. rosella. 

 + + Leaves sessile or nearly so, the base rounded or cordate. 



Tree ; corymbs on a peduncle 1 — 1| in. long, J. brimnescens. 



X X Cymes or corymbs short-peduncled or sessile, the flowers sessile or 

 shortly and stoutly pedicelled. 

 + Flowers white or rarely pale rose-coloured (never orange or scar- 

 let), the corolla-lobes often comparatively narrower. 

 O Corolla puberulous or pubescent outside. 

 All parts more or less pubescent ; cyme rather small, almost sessile ; leaves pubescent, 



sessile, /• Brunonis. 



O Corolla glabrous, rarely the throat bearded. 



t Flowers sessile. Corolla-tube | — f in. long, the thi'oat 

 naked. 

 Shrub ; leaves sessile with a rounded or cordate base ; corymb glabrous, 



. . /. memecylifolia. 

 Shrub ; leaves petioled, the base acute or obtuse ; corymb glabrous, .... I. sessiliflora. 



Tree ; leaves petioled, the base acute or obtuse ; cymes puberulous, p I. rugosula. 



t t Flowers shortly pedicelled. Corolla-tube \\ — 2 in. 

 long, the throat bearded. 



Glabrous, also the inflorescence ; leaves sessile or nearly so, /. Brandisiana. 



-h + Flowers orange to deep scarlet, very rarely (in varieties 

 chiefly) white or pale rose-coloured, and in this case the corolla- 

 lobes always much broader than those of the white-flowered sec- 

 tion, 

 Calyx-teeth very short. 



t Inflorescence puberulous.
