and turning its micropyle up- 
wards and inwards. The fruit 
is said to be dry, ovoid, turbi- 
nate, acuminate, traversed by 
ten longitudinal grooves, with 
coriaceous, fungous, indehis- 
cent pericarp. It contains a 
seed, the coats’ covering a 
fleshy embryo, with superior 
radicle, straight and short, 
and large, thick, fleshy’ coty- 
ledons. The only known spe- 
cies of this genus, P. Rhizo- 
phore; is a tree growing in 
the marshes near the sea, at 
the extreme north-west of 
South America, and which 
has the appearance of the 
Mangrove. All its organs 
are glabrous; its leaves alternate, nearly sessile, involuted in verna- 
tion, are unsymmetrical at the base, glabrous, and coriaceous. The 
edges, when young, are furnished with very small, prominent, 
triangular,’ caducous teeth. The flowers’ are solitary and terminal,’ 
and each of them enveloped in the bud by two large membranous 
involute bracts. 

VI. MARCGRAVIA SERIES. 
The flowers of Marcgravia' (figs. 269-277) are hermaphrodite and 
regular. The receptacle, in the form of a depressed cone, bears first a

tinguish two forms which should perhaps be 
two species, distinguished from each other by the 
colour of the flower and the number of ovary 
cells.

the upper leaves. It seems to us that the short 
thick peduncle supporting the flower is the 
extremity of the branch, and that the pointed 
shoot upon the side is not terminal, but placed 
in the axil of the leaf preceding the flower.
