minute and subglobose with about 
3 exposed scales, the terminal 
larger, ovoid, with some half- 
dozen ciliate scales. lLeaf-scars 
alternate, clustered toward the end 
of the season’s growth, broadly 
crescent-shaped, somewhat raised:

ing. Leaves simple, entire, spatu- 
late-obovate in the following. 
An odoriferous resin, produced 
in passages that are characteristi- 
cally distributed in the tissues and 
which is especially abundant in 
the fruit, renders this a favorite 
source of incense for church purposes in the Azores.
