likewise matches the type. Unfortunately, it bears no 
data concerning the locality or date of collection nor a 
collector’s name, but I believe it to be a duplicate type. 
The only annotation it bears is the following: ‘‘dedit 
Willdenowius, 1811.”’ 
Hevea guianensis 4ub/et Hist. Pl. Guian. 2 (1775) 
871. 
In the Paris Herbarium, there are two sheets of Hevea 
guianensis upon which is written: ‘‘Leg. A. Richard. 
Sta. Martha Antilles. Siphonia elastica ex hb. de Fran- 
queville. Herb. E. Cosson 18.°’ The special interest at- 
tending these particular specimens centers on the locality 
data. The only ‘‘Sta. Martha’’ which I have been able 
to find registered for the entire Antillean area is the very 
old city of that name on the Caribbean coast of Colom- 
bia. The genus Hevea, of course, is unknown from that 
region, and we may very safely assume that it does not 
exist there in a natural state. 
I believe this to be an erroneous annotation. The speci- 
men corresponds so very closely to other material of 
Hevea guianensis from French Guiana (including speci- 
mens also collected by Richard) that I am convinced 
that it was collected in that colony. Louis Claude 
Richard, who was commissioned in 1781 to carry out 
explorations in French Guiana and the Antilles, spent 
much of his time in French Guiana, later travelling in 
Martinique, Guadeloupe, Jamaica, St. Thomas, and some 
of the islands in the Gulf of Mexico (cf. Laségue ‘‘Musée 
Botanique de M. Benjamin Delessert’’ (1845) 474). 
Hevea is known in a native state in none of these areas 
except French Guiana.
