descending collateral ovules, very incompletely anatropous, the short 
Suriana maritima.

raphe looking downwards and inwards. The fruit, accompanied by 
the persistent calyx, is formed of five drupes (or fewer) almost com- 
pletely dry, the stone containing a campylotropous ascending seed, 
the coats covering a large fleshy embryo, folded upon itself, so that 
the incumbent cotyledons and superior radicle have their summits 
near the point of attachment. S. maritima,’ the only known species, 
is a shrub frequently met with on the sea-coast of all tropical coun- 
tries. It is tastless, covered with capitate hairs. The leaves are 
alternate, simple, narrow, articulate at the base, besprinkled with 
glandular punctures. The flowers are united towards the extremity 
of the branches in false racemes of uniparous, short, few-flowered, 
but ramified cymes. 
Rutacee, thus comprised, constitute a family by concatenation 
with many affinities, the fourteen series presenting the general cha- 
racters which follow.
