like floriferous branches axillary elongated, simple or slightly 
divided in short pedicellate cymes (Zrop. West. Africa). 
90. Hyptiandra Hook. ¥.?— Flowers hermaphrodite, usually 
5-merous ; receptacle shortly conical. Sepals small free. Petals 
alternate, much longer, dorsally pilose, imbricated. Stamens 10, 
5 oppositipetalous shorter; anthers introrse, 2-rimose versatile. 
Gynæceum placed on glandular thick depressed conical disk ; germens 
free oppositipetalous villous ; ovules in each 1, descending ; micropyle 
extrorse superior ; styles inserted at summit of germens, afterwards 
coalescing among themselves in short column, at apex only stig- 
matiferous free minutely capitellate. Fruit carpels 1 or more, 
seated on acute obpyramidal receptacle compressed ovate, subdru- 
paceous ; exocarp subcoriaceous, putamen 1-spermous; seed ventri- 
fixed ; testa membranous; albumen very scanty; embryo straight ; 
cotyledons ovate plano-convex; radicle short superior. — Shrub 
somewhat glabrous, younger branches pubescent; leaves alternate 
(bitter’) narrow lanceolate entire coriaceous ; flowers small, shortly 
pedunculate, axillary, solitary or few (Hast. Subtrop. Australia’). 
91. Castela Turr.— Flowers dicecious, 4-merous ; receptacle short. 
Calyx small, 4-fid. Petals 4, longer, imbricated. Stamens 8, 
2-seriate ; filaments free inserted below 8-crenate disk; scales 0, or 
very short; anthers (sterile in female flower or 0) 2-locular, at 
margin or extrorsely rimose. Carpels 4, oppositipetalous (rudimen- 
tary or 0 in male flower), seated on disk; germens free; styles co- 
alescing at middle, at apex inwardly stigmatiferous revolute ; ovules 
in germens solitary descending incompletely anatropous ; micropyle 
extrorse superior. Drupes 4 (or fewer from abortion), free patent ; 
mesocarp usually thin ; putamen crustaceous ; seeds descending, with 
wide funicle; testa membranous; albumen thin; embryo inverse ; 
cotyledons plano-convex ; radicle superior.—Shrubs ; branches often 
spinescent; leaves alternate small very shortly petiolate entire
