similar to, but always smaller than, those typical of the 
species itself; the capsule usually measures about 4 cm. 
long. 
Ducke published Cunuria bracteosa in 19838, but a 
year previously he had said (in Notizbl. /oc. cit.) that ‘‘zu 
dieser Art [C. Spruceana]| gehért wohl sicher das Herb- 
armaterial das unter dem Namen Cunuria bracteosa nov. 
spec. von mir verteilt wurde; wahrscheinlich ist iibrigens 
diese Gattung monotypisch.’’ It is obvious that Ducke 
continued to regard his species, Cunuria bracteosa, as 
synonymous with C. Spruceana, because his more recent 
collections of the former concept have all been deter- 
mined by him as representing the latter, and, in 1934, 
he reiterated his opinion that C. bracteosa should be re- 
garded as a synonym of C. Spruceana (in Arq. Instit. 
Biol. Veget. Rio Jan. 1, no. 2 (1984) 91, footnote 1). 
A letter from Ducke (April 1982) attached to A. 
Ducke 23519 in the Kew Herbarium states: ‘‘I distrib- 
uted the no. 23519 with the name Cunuria bracteosa 
n.sp. (Sao Paulo de Olivenca, Solimées River), but lately 
I collected similar material on the upper Rio Negro, typi- 
cal region of Cunuria Spruceana. Cunuria bracteosa dif- 
fers of the description of Cun. Spruceana by bracteae 
well developed and by the glandulae of the exterior of 
the male flowers receptacle, but I now presume that 
Spruce did not collected material in good conditions and 
that the Cunuria might be only of one single species. 
Still, I dare to say that the flowers as well as the cap- 
sules and seeds may vary in size on the same tree enor- 
mously. Consequently, I resolved not to publish mean- 
while my supposed new species.’
