A. lasiospatha, Mart : 
Local Name. 
Arawak Yawarra. 
Measurements. — Height to base of leaf-stalks = 37 feet. 6 in. ; Girth 
of stem at ground = 3 ft. 10 inch : half-way up = 2 ft. 6 in: at top = 2 ft. 
3 inch. Length of leaf = 8 ft. 8 inch. Breadth of leaf = 3 ft. 6 inch. 
Leaf of pinnae = 2 feet. 1 inch, of rachis = 4 ft. 3 in. 
A few aerial roots. Spines deciduous on trunk 
but persistent on leaf. The most recent leaf stands 
upright in a very bold way, the rest are very much 
curved ; so that the whole head of the tree has a globular 
outline. 
Fruit large, round, compressed, yellow. Spathes 
very long but narrow, without prickles but rusty-villous. 
Leaflets very narrow, almost linear. 
The trunk, in the specimens measured, was not 
swollen in any part, but gradually decreased from the 
base upward. A. lasiospatha of Martius is, however, 
said to have a ' ventricous middle part.' 
This is by no means a common palm in the colony. A 
large group crowns the " Second Hill" on the Corentyn 
river. The hill on which stands the old settlement 
of " Peerboom" on the Berbice river also has a large 
number of Acrocomias on it which probably belong to 
this species. And it is said to grow at Hitchia, and also 
at one or two other spots, also on the Berbice. I do not 
know it elsewhere.
