82. PETALOSTYLES, R. Br. 
(Style petal-like.) 
Sepals 5, much imbricate, somewhat unequal, scarcely connected at the base. 
Petals 5, spreading, nearly equal. Stamens 3 perfect ; filaments very short ; 
anthers linear, the cells opening inwardly in longitudinal slits; 2 small staminodia, 
with acuminate imperfect anthers. Ovary nearly sessile, with several ovules ; 
style large and petal-like, saccate immediately above the ovary, with 3 erect lobes, 
2 short ones in front, the other much longer, concave, the midrib prominent 
inside and terminating at the top in a small stigma. Pod flat, oblong-linear, 
oblique, 2-valved. Seeds ovate-oblong, compressed ; testa shining ; funicle 
expanded into a fleshy appendage distinct from the seed ; albumen copious ; coty- 
ledons flat. — Shrubs. Leaves simply pinnate. Flowers yellow, on axillary 
peduncles. 
The genus is limited to a single species, endemic in Australia, very nearly allied to Cassia 
(sect. Chamacrista) and to Labicliea, but distinguished especially by the very singular style. —
