trema in lacinias quinque antheriferas lineares, 4—5 mm. 
longas producta; laciniis sex antherarum loculis, oblon- 
gis, 1-1.2 mm. longis, valde contiguis munitis, et loculis 
alteris (1-2) parte superiore tubo concrescentibus. Stylus 
longe villosus, antherarum lobulis parum brevior vel ae- 
quilongus. Stigma capitatum, 1.8 mm. crassum. 
In connection with the foregoing description, Cuatre- 
casas states: ‘‘Quararibea Schultesiu belongs to the small 
group of species which have wings on the calyx. The 
most similar to it is Quararibea bracteolosa (Ducke) 
Cuatr. but Q. Schultesiu differs in having longer petioles 
and pedicels, by its smaller flowers, by the shorter mem- 
branaceous calyx of which the wings are more expanded 
and even more membranaceous, by the herbaceous- 
membranaceous lanceolate bracts, and by the indumen- 
tum of calyx and bracts which is shorter and thinner. 
Quararibea bracteolosa, on the contrary, has bracts which 
are ovate and coriaceous or subcoriaceous, a calyx tube 
which is much thicker and dense. I have seen an isotype 
of Quararibea bracteolosa which is preserved at the 
Chicago Museum of Natural History. Probably Ducke 
1781 and 1782 (fruiting specimens), distributed as Quar- 
aribea bracteolosa, do not belong to that species. ”’
