seeds which are provided with an arillus, that appendage 
is not developed till after the fecundation of the infant 
ovulum. If the unimpregnated ovulum of our subject 
be examined, no traces will be discovered of the arillus, 
which is subsequently so rapidly formed as, in maturity, to 
_ form a complete wrapper for the seed. This may perhaps 
have given rise to M. Decandolle’s mistake in supposing 
that the seeds of Hibbertia are destitute of arillus. 
A neat little greenhouse plant, with the appearance of 
some small-leaved Helianthemum. Our drawing was 
made from Mr. Lee’s Nursery, in June 1825. 
An undershrub about a foot high, in wild specimens 
nearly erect, in cultivated plants decumbent. Branches 
filiform, round, hairy. Leaves linear, sessile, obtuse, some- 
what toothletted at the edge, slightly hairy, the adult 
leaves being reflexed. owers solitary, terminal, stalked, 
with a filiform, hairy, coloured peduncle. Calyx with one 
little bractea, 5-leaved ; sepals concave, hairy, imbricated, 
somewhat unequal, coloured either at back or margin. 
Petals yellow, sessile, oblong, emarginate. Stamens yellow, 
hypogynous in a simple series ; fi/aments subulate ; anthers 
continuous, innate, obtuse, turned inwards, bursting at the 
sides. Ovaries 3-5, roundish, silky; ovules in each oya- 
rium 6, horizontal, adhering to the inner edge of the 
ovarium, without arillus; with an obscure foramen next 
the hilum. Sty/es subulate, spreading ; stigma quite simple. 
Carpella membranous, 3-4-seeded. Jmmature seeds involved 
in a transparent lacerated arillus; testa pale and ae
