Jatropa urens produces he says a kind of Balata very easy to 
work and easy to propagate from seeds or cuttings. This may be so, 
but it is not likely to be popular as a cultivated plant as it is one of 
the worst stinging plants in the world. It is quite a small plant and 
at Fernando de Noronha where I met with it in abundance, the 
botanists of the Challenger expedition said the only way to gather 
it was to lasso it with a string, haul it up and drop it in to the 
botanical papers and drop a weight on it. It is impossible to touch 
the plant without being stung. 
These plants, Seffer says, grow usually in ground unsuited 
for agriculture and will give 75 pounds of rubber per acre. The 
Plumieras are big enough to tap in three years, and the rubber can 
be placed on the market at 2 fr. 50 per kilo at most. An English 
Syndicate is just formed to exploit these plants with a capital of 
7,500,000 francs. — E d. 
SOME CORRECTIONS. 
Mr. Trelease sends the following note as to references concerning 
the publication of the account of the Zapupe, in Bulletin No. IX. p. 569. 
THE MISSOURI BOTANICAL GARDEN. 
Dear Doctor Ridley, 
St. Louis, Mo., 
January 24, 1910. 
I am pleased to learn from the December number of the Agri- 
cultural Bulletin that you are taking interest in the new Zapupes. 
I notice, though, that through some inadvertence you refer to Consul 
Millward’s pub ication as having been contained in the Transactions 
of our local Academy of Science. His several important practical 
papers were actually published in our Government Consular Reports, 
or in periodicals, while it is only my own paper on the subject (which 
I sent you when I sent you the bulbils that you are growing) that 
was published by the Saint Louis Academy. 
Sincerely yours, 
Wm. TRELEASE, 
Director. 
In the Bulletin for March, p. 84, the omission of a line in the 
fourth paragraph makes the passage obscure, and it should read 
line 29 “nor does the suggestion that ” and that thus the 
cotton is not affected after the death of the sorghum, does not seem 
to make matters any clearer.
