quite unknown to us and must be very rare; the most diligent 
search of tree-trunks and rocks failed to reveal another of the 
same kind; the plant was preserved in formalin for Mr. Ames’ 
examination. 
One object in visiting Bath was to see the rare tree Prioria 
copaifera, definitely known to us to grow only in the vicinity of 
that place, although reported to occur also in Panama; it is 
locally known as oil-tree and gum-tree, its wood containing an 
inflammable heavy oil or liquid resin, which gives off dense black 
smoke when burned; it was discovered here before 1860 by 
Nathaniel Wison, for many years curator of the Bath Botanical 
Garden and a diligent collector who contributed much to the 
knowledge of Jamaica plants; its generic name commemorates 
the important botanical work of Dr. R. C. Alexander Prior in 
Jamaica. We failed to find it on the Cuna Cuna road. Mr. 
Harris had visited the district in search of this tree some years 
ago, and had found one at Mansfield, a short distance from the 
town. We therefore visited the estate, where we were cordially 
received by the owner, Mr. A. H. Groves, who kindly gave 
us permission to ke his woodlands. We made collec- 
tions of many plants, including some fine orchids, but did not 
find the tree sought for. The valley of the Devil’s River on this 
estate proved very interesting, but we were driven out by rain in 
the afternoon and could not explore it thoroughly. 
The next day we again set out to find Proria, going to Bache- 
lor’s Hall estate where it was first discovered by Wilson. After 
climbing over the foothills of the John Crow Mountain range all 
day, with only ordinary success, we were finally rewarded at dusk 
and again in the rain, by finding it in a valley at an altitude of 
about 600 feet. The tree is a magnificent one, forming a straight 
smooth cylindric trunk rising to at least 90 feet, the head of dark 
green foliage being oblong in outline. It was not in flower at 
the time, but we obtained specimens of the foliage from a young 
specimen and plenty of fruits and young seedlings on the ground 
under a large tree. The genus is of the Senna Family and has 
remarkable fruits, these being woody one-seeded, somewhat heart- 
shaped pods, about three inches across, the seed germinating in-
