the twigs, lj-2i in. long, with many rather dense male liowers above 

 and 1-2 basal female flowers, in both sexes very shortly pedicelled and 

 solitary to their bracts ;. bracts 3-lobed, central lobe lanceolate, acute, 

 twice as long as the two lateral suborbicular glandular lobes. Male : 

 Calyx deeply 8-sect ; lobes triangular, denticulate. Stamens 3, hardly 

 exserted. Female ; Calyx 3-paitite ; lobes suborbicular, denticulate, 

 eglandular. Ovary glabrous, not horned ; styles 3, almost free. Capsule 

 not seen ripe; its valves thinly crustaceous. Seeds nairow-ovoid, 

 smooth, yellow. — Excaxaria farad ianens is, Beille in Bull. Soc. Hot.

A very distinct species, reiiiiily recognised by its hyaline and denticulate leaf- 

 margins. Beille describes tlie cocci of the unripe cap&ule as appendaged on the back. 

 There is, however, no trace of appendages on the ovary itself in the liowers exainine<l 

 by us and the appearance described, which is also met witli in }OUiig capsules of 

 S. Gra/iami,is perhaps the result of irregular shrinking of the thin capsule-walls in 

 drying. The species is most nearly allied to S. Grahami.

 Hippoman. '24:-i,Jig. 46 E. A shrub or small tree, reaching 15-16 ft. in

 2^ in. wide, dark green above, paler beneath; lateral nerves 13-10 on 

 each side ; petiole slender, ^-^ in. long, slightly channelled above ; 

 stipules very caducous, not seen. Spikes terminal on the twigs, male 

 portion not seen, with usually 2 distinctly pedicelled basal female flowers ; 

 female bracts ovate, ^ in. long, eglandular, with ciliately laciniate 

 margins, each 1 -flowered ; pedicels in fruit J-| in. long. Female: 

 Calyx deeply 3-sect ; lobes wide-ovate, acute, denticulate, with a small
