3 P. acumina'ra (Willd. rel. in Roem. et Schultes, syst. 5. p. 
23.) leaves ovate, acuminated. h.S. Native of New Spain,

Acuminated-leaved Portlandia. Shrub. 
Cult. The species of Portléndia are deserving of a place in 
every collection of stove plants, for their large showy flowers. 
They thrive best in a mixture of sandy loam and peat; and 
cuttings, not having their leaves shortened, will root freely if 
planted in a pot of sand, plunged in heat, with a hand-glass over 
them. A strong heat is necessary for flowering the species, and 
without it they will not even grow freely.

Lix. syst. Tetréndria, Monogynia. Calyx witha turbinately 
oblong tube, which is angular from 8 filiform ribs, 4 of which are 
carinal, and 4 sutural: and a 4-parted limb; lobes linear-lan- 
ceolate. Corolla clavate, tetragonal, with a 4-parted limb. 
Anthers 4, linear, not exceeding the limb of the corolla. Stigma 
unknown. Capsule ovate, dehiscing at the apex, separable from 
the calyx, and therefore at length becoming naked, 2-celled, but 
almost 4-celled from the margins of the valves being involute ; 
valves bifid at the apex. Placentas narrow, rather prominent. 
Seeds innumerable, small, compressed, not winged, but echi- 
nated along the margins from membranous crests. Albumen 
fleshy.—A glabrous shrub. Leaves opposite, obovate, bluntish,

Stamens inserted in the bottom of the tube of the corolla, and 
about its length; filaments capillary, villous at the base, and 
combined together in a monadelphous manner ; anthers oblong;

bilamellate ; lamellae oblong, obtuse. Capsule almost globose, 
pentagonal, truncate at the apex, crowned by the segments of

from being pressed against each other, girded by a cup-shaped 
membrane at the base.—A stiff shrub, with the habit of Ernòdea. 
Leaves opposite, linear, stiff, with revolute margins. Stipulas 
on the younger branches entire and subulate, but those on the 
older branches are bipartite. Flowers almost terminal, solitary, 
nearly sessile, often hexamerous. i
