i»ear the Upper Essequibo and very abundantly along the Rupununi 

 and Takutu, the heart of which is highly ornamental, but not more 

 than 6 inches in diameter, and very subject to holes. 



Maipuremu (Vantanea Guianensis, AubL). Wood very subject to 

 worms, and not likely to become of much use ; but the tree presents 

 a beautiful appearance with its large clusters of pink flowers, and is 

 even more remarkable for its drupaceous fruit, which is furrowed like 

 our peaches and almonds, and is cut in half by the Indians to form 

 ornaments, chiefly for the children. 



Camara, Camacusack, Makoripong , or Ackatvai- Nutmeg {Acrodicli- 

 dium Camara, Scho7nb.}. Timber most like the Siruaballis, aromatic 

 and bitter, and consequently resisting worms and insects. Trunk 

 40 or 50 feet high, with a circumference of 8 to 10 feet, and apt 

 (like the Yarura and Mora) to form tabular projections at the lower 

 part. Chiefly prized for its aromatic fruit, which is considered one 

 of the most eflficacious remedies in colic, diarrhoea and dysentery. 



Greenheart, Sipiri (Nectandra Rodiaei, ScJiomb.^. The brown 

 Greenheart is one of the most useful timber-trees of the colony, and 

 is found in great abundance within 100 miles of the Coast Region. It 

 grows to the height of about 60 feet, and is generally used for house- 

 frames, wharfs, bridges, piles and planks. Within the last twenty 

 years a large quantity has been imported into Liverpool and Green- 

 ock ; and it has been even asserted that in strength and durability 

 it is superior to English oak, than which it commands a higher 

 price. In times of scarcity the Indians obtain from its fruit, grated 

 and macerated in water, a fecula which is mixed with the rotten 

 wood of the Wallaba-tree, pounded, sifted and baked into bread, in 

 like manner with the Cassava. In the bark and also in the fruit. 

 Dr. Rodie of Demerara has discovered a substance which forms an, 

 excellent substitute for quinine, and to which he has given the name 

 of biberine. The black greenheart appears to be a mere variety, 



Cartan-yeh of the Macusi Indians, Pao da Rainhaof the Brazilians. 

 Apparently restricted to the Savannahs in the neighbourhood of the 

 rivers Rupununi, Takutu, Branco, &c. The Brazilian name is de- 

 rived from the red colour of the wood, which resembles that of the 

 Brazil-wood of Pernambuco, to which the same name (Queen's- 

 wood) is applied. It reaches a height of 80 to 100 feet ; and being 

 easily worked and of a handsome colour, promises to become of great 

 interest to cabinet-makers. It was used by the author during his 

 sojourn in Pirara for temporary tables, and the large size of its 

 planks induced the military commandant to construct of it a tem- 

 porary bridge across the river. The leaves are impari-pinnate, the
