acuminate, considerably smaller than the petals; the latter, one- 
third or more longer than the sepals, very broadly obtuse or else 
cucullate at the apex. Fruit regularly ovoid-ellipsoid, equally 
narrowed at both ends, 63 mm long and 35 mm through (in 
two specimens) or a little less than twice as long as broad. 
The pericarp is 5 to 6 mm thick at the sides, and only in its 
outermost half at maturity does it disintegrate into capillary 
fibers, its inner half remaining woody; the apex in its internal 
part is also woody, but the base is entirely fibrous. The seed 
is inserted a little below the lower third of the entire fruit, 
ovoid with a flattish base and a very obtuse apex, 28 mm long, 
22 mm broad; the vascular branches of the integument are very 
numerous and arise parallel and undivided at an acute angle 
from the base, anastomosing only above and on the ventral or 
antiraphal side; the rumination of the albumen is produced by 
numerous straight and descending lamella. Embryo broadly 
ovoid.

This is a wild-growing species approaching Areca Catechu, 
although doubtless specifically distinct from it. The spadix, in 
flower, has the appearance of that of A. Catechu, but its flori- 
feroys branches are more robust and strongly zigzag-sinuous 
in the male flower-bearing portion. The male flowers are larger 
and broader than those of Areca Catechu and differ also in 
having very blunt anthers and a short rudimentary ovary. Fur- 
thermore, the female flowers of A. parens differ also from those 
of A. Catechu especially in the sepals being considerably shorter 
than the petals, the latter being usually blunt and more or less 
cucullate at apex. The fruit of Areca parens resembles that of 
A. macrocarpa, but differs from the fruit of all the species ap- 
proaching A. Catechw in having the outer half of the pericarp 
disintegrable into soft fibers only, the inner half being woody. 
The seed is also characterized by the very numerous vascular 
branches of the integument lying close together, parallel and 
undivided laterally and on the raphal side, and by the lamellz 
which cause the rumination of the albumen being straight and 
inclined toward the base of the seed.
