Acuminated-\eaved Portlandia. Shrub. 



Cult. The species of Portldndia 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.

LXII. ISIDO'REA (isidos is the Latin name of a shrub like 

 coral ; the name has been applied to this genus because it is stiff 



and dry, and grows by the sea side). A. Rich, in mem. soc. hist,

 throat, and a 5-cleft limb ; segments triangular, acute, short. 

 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 ; 

 obtuse at the apex. Style slender, length of corolla ; stigma 

 bilamellate ; lamellae oblong, obtuse. Capsule almost globose, 

 pentagonal, truncate at the apex, crowned by the segments of 

 the calyx, 2-celled ; cells dehiscent, many-seeded. Seed angled, 

 from being pressed against each other, girded by a cup-shaped 

 membrane at the base. A stiff shrub, with the habit of Ernodea. 

 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.
