292 ODOROGRAPHIA. 
bisci Creek of the Essequibo River, in loose, sandy soil ; its wood 
is little used, as it decays rapidly on exposure to the weather. 
The average height of the tree is about 50 feet. The Caribbee 
name for this is “ Arouaou.”’ Another wood of strong aromatic 
scent, resembling the “ Hyawa,” also found along the Itoori-bisci 
Creek, Essequibo River, and growing plentifully in the loose, 
sandy soil, is locally called Oulu; its average height is about 
90 feet. This produces a gum resembling “ Hyawa,” but in much 
smaller quantities*. Its wood is the colour of pale cedar, and 
should be useful for drawers and shelves of wardrobes. The 
timber will square 16 to 18 inches. 
The Icica Icicariba, D.C.t, is a native of Brazil, where it is 
called “Icicariba” and “ Resina Icica.” It produces a sweet- 
scented gum which is used as incense. The Icica decandra, Aublett, 
is a native of the woods of Guiana, where it is called Chipa. It 
is the Amyris decandra of Willdenow§, and is synonymous with 
I. pentandra, Aublet ||. When the bark of this tree is wounded a 
whitish liquid flows out, which has a scent of citrons, when dry 
becoming a yellow transparent resin, which is found in small 
pieces under the bark. The resin is carried by the Caribbees to 
Cayenne, where it is employed in churches as incense. 
The balsams obtained from some of the species of [cica remain 
fluid for a considerable time, but ultimately harden, and are then 
used for burning in the churches. Some of the trees are so highly 
charged with resin that the branches can be used as torches. 
Other aromatic woods from British Guiana, derived from trees 
not botanically identified, are locally known as “ Keritee” or 
“ Kretti” from the Aroua-pia-kooroo Creek, Pomeroon River; a 
wood which is plentiful in some localities. It has a strong aro- 
matic scent, is light, and im colour and appearance resembles 
satin-wood. Its average height is 80 feet, and its timber will 
square 20 inches. The ‘‘ Yellow Cirouballi” or “ Sirua-balli,’’ 
also from the Aroua-pia-kooroo Creek of the Pomeroon River, is 
light, of bright yellow colour, and strong aromatic scent. It often 
grows to a very large size, averaging in height 60 feet, and prefers 
a sandy soil. Its bark is useful for tanning.
