A climbing plant with slender branches, and axils 14 in. apart: its spreading leaves 
are 3-37 in. long, 12-21 in. broad, on a petiole 3 lines long: the panicles, more fre- 
quently in the axils of the younger branchlets, are 1-13 in. long, the peduncle 6-7 lines 
long, the primary branches 5 lines, the secondary 4 lines, the rest diminishing upwards, 
all verrucose on their sharp angles; sometimes the first articulation is trichotomous, but 
all the remaining branchlets are dichotomous, either bare or with a solitary flower in 
each dichotomy; the flower expanded is 3 lines in diameter, the sepals 3 line, the petals 
1i line long, À line broad, pedicel 14 line long. 
7. CLERCIA. à; 
This genus, proposed in 1825 by Padre Velloz, has not been recognized by botanists : 
he figured 2 species in his * Flora Fluminensis,' one of which must be rejected, as it belongs 
to Raddia. The Macahanea of Aublet has a fruit with seeds so very similar to that of 
Velloz's typical species that I have no hesitation in referring it to Clercia. This genus is 
distinguished by its very divided dichotomous inflorescence with extremely slender rami- 
fications and copious very small flowers, dark fleshy sepals, petals, and disk, in which 
respects it approaches Tontelea ; but it differs widely in the size of its fruit and seeds, the 
difference being remarkable.
