Botanic Gardens, we know three of these rubber-plants 
from which small quantities of rubber have been obtained 
and examined, but larger quantities are needed before, 
from a commercial standpoint, they can be compared 
with the different kinds in the market. These three 
plants pass under the common names of " Hatie," " Touch- 
pong," and " Macwarrieballi." 
The " Hatie" (Hevea spruceana) is closely allied to 
the Para rubber-tree {Hevea brasiliensis), and grows in 
the colony in corresponding situations to its southern 
representative ; that is, in alluvial lands more or less 
swamped and inundated at high water. The tree grows 
to a height of from 40 to 60 ft., with a diameter of about 
twenty inches, straight of trunk among other trees of the 
forest, but spreading and branching by the waterside 
where it is exposed. " The leaves are trifoliate, on long 
stalks crowded together towards the ends of the branches 
from between which the flower opens. The leaflets are 
entire, oblanceolate in shape, acute, polished green above 
and bluish green beneath. The fruit is a three-cornered 
capsule with seed of the size ot a small nutmeg." The 
Hatie is common in the upper estuaries of the great 
rivers and in the various creeks leading therein, but the 
trees are always more or less scattered, though an abun- 
dance of young plants ca»i be obtained in their neigh- 
bourhood. 
The Touchpong (Sapium higlandulosum) appears to 
be a common tree both on the highlands of the interior 
and on the lowlands of the coast. Examples are met 
with in many parts of Georgetown where they are known 
by the common name of gum-tree. It is closely related 
to the Jamaica milk-wood or gum-tree, and grows to a 
larger size even than the bullet-tree. It will readily 
be recognised by its broadly lanceolate, entire leaves, of 
from 5 to 9 inches in length, with two glandular spots, on 
one each side of the short stalk at the base. 
The Macwarrieballi (Forsteronia gracilis) is one of the 
bush-ropes of the interior, where it appears to thrive in 
the more rocky and gravelly places. Mr. Jenman found 
it on the high ground near the Great Falls, Demerara 
River. It is closely allied to the milk-withe of Jamaica,
