annotated ‘‘Gummi elastique’’ but which had not been 
labelled with a Latin epithet. This Brazilian specimen ' 
is neither Jatropha nor Hevea but, curiously, would 
seem also to be a rutaceous plant, Msenbechkia febrifuga 
(St. Hil.) Mart., likewise a source of bitters and often, 
in an earlier period, used to adulterate or falsify true 
Angostura-bitters. It naturally does not represent a lac- 
ticiferous plant, and the annotation with reference to 
gum elastic is as erroneous as the analogous annotation 
on the sheet of the Mutis specimen of Cusparia trifolata 
and was undoubtedly made for the same purpose. 
We wish to express our appreciation to Spencer 
Savage, Esq., Assistant Secretary of the Linnaean So- 
ciety, for his very kind help in the study which has led 
to the clarification of the erroneous record of a Mutis 
collection of Hevea. 
7 The Brazilian specimens in the herbarium of Linnaeus were prob- 
ably collected by Joaquim Velloso de Miranda (1733-1815) and sent 
to Linnaeus by Domenico Vandelli (1735-1816). He collected in 
Minas Geraes.
