EUHEVEA 
Hevea guianensis 4 ub/et Hist. Pl. Guyan. 2 (1775) 
871. 
There are two collections in the De Candolle Her- 
barium which Mueller refers to this concept. I have an- 
notated them both as Hevea guianensis. 
Frencw Guyana: 1840, Leprieur. 
The Leprieur collection, represented also at Paris, 
seems to be the earliest flowering material of Hevea 
guianensis. Mueller has left a label in his handwriting, 
which reads: ‘‘Euphorbiae. Calyx ad mediam usque 5- 
partitus, petala nulla, stam 5! circa rudimentum ovarii 
in columnam coalita, filamenta subnulla, fol. stipulata. ”’ 
Frencu Guyana: Maroni, 1857, P. Sagot 510. 
The Sagot collection is represented in several herbaria. 
The specimen in the De Candolle Herbarium is in abun- 
dant flower. 
2. Miscellaneous notes, chiefly on specimens of Hevea 
in various European herbaria 
Hevea brasiliensis (Willd. ex A. Juss.) Mueller- 
Argoviensis in Linnaea 84 (1865) 204. 
Brazit: [Near mouth of Rio Amazonas] Sieber s.n. [?] 
The Humboldt Herbarium in Paris has a collection 
referable to Hevea brasiliensis and consisting of one leaf- 
let and several flowers in a little packet. The packet is 
labelled ‘“Stphonia brasiliensis W. (e specim authent. ab 
ipso Willdenow misso),’’ and is evidently a fragment 
from the type specimen in the Willdenow Herbarium 
collected by Sieber, which it matches perfectly (ef. 
Schultes in Bot. Mus. Leafl. Harvard Univ. 14 (1950) 
79). 
In this same herbarium, there is a full specimen which
