432 NATURAL HISTORY OF PLANTS. 
resembles that of Cinuamomum, becomes transformed into the one- 
seeded fruit, the receptacle goes on increasing in height and 
thickness, so. as to envelope the whole fruit. On 
top thereof (fig. 246) is seen a narrow opening: 
this is surrounded by the scars of the perianth in 
Cryptocarya ; but the perianth persists to the last 
in Cyanodaphne, of which some have made a sepa- 
rate genus. Or again the accrescent receptacle is 
closely applied and almost adnate to the pericarp, 
as we find in Caryodaphne; similarly made by 
some a distinct genus, and reduced by us to a 
section of the genus Cryptocarya. Thus constituted,* 
this genus consists of trees and shrubs, with their 
leaves alternate, and their flowers in ramified axil- 
lary and terminal racemes of cymes. They inhabit nearly all 
tropical regions. Of the forty-three known species,’ five or six 
are American. 
Boldu? has altogether the flowers of Cryptocarya ; the same 
receptacle and perianth, the same androceum, with nine of its 
stamens fertile and two-celled, the same gynzceum inserted in 
the bottom of the receptacular sac. But the last, instead of 
becoming thickened, as in Cryptocarya, remains thin, dry, and 
fragile. It forms a completely closed sac around the fruit, and is 
covered by the scars of the perianth ; it breaks, however, at the 
least touch, and it is often the fruit itself that appears by its 
growth to burst it and make it fall at a variable period. Only 
two species of Boldu are known,° trees from Chili, with their 
leaves opposite, or nearly so, and with axillary inflorescences like’ 
those of Cryptocarya.
