This is a scandent plant, with the axils of its branches 14-2 in. apart; the leaves are 
21—4 in. long, 1-13 in. broad, on a petiole 3-5 lines long; the peduncle of the inflo- 
rescence is 1-17 in. long, the primary branches 4-7 lines long, the rest becoming gra- 
dually very short, the flowers being thus aggregated: these are 3 lines in diameter 
when expanded, on pedicels 1 line long. 
20. HIPPOCRATEA DIFFUSA, nob.: ramulis validiusculis, patentissime divaricatis, rugoso- 
striatis, glabris, teretibus, axillis subremotis : foliis ovatis aut obovatis, imo obtusis 
vel rotundioribus, apice rotundatis et in apiculum brevem obtusum sub-naviculari- 
recurvatum repente constrictis, marginibus cartilagineis reflexis grossule et obtuse 
serratis, coriaceis, rigidis, supra viridibus, minute punctulato-rugulosis, tactu sub- 
asperulis, nervis tenuibus arcuatim nexis fere immersis, subtus haud concoloribus, 
opacis, costa prominula, nervis venisque valde reticulatis vix conspicuis; petiolo 
canaliculato, subtus ruguloso, striato, imo 10-plo breviore: paniculis axillaribus et 
terminalibus, corymbosis, rufulo-tomentosis, opposite ramosis, ramis dichotome 
divisis, cum ramulis 2 brevissimis paucifloris in dichotomiis; floribus in ramulis 
ultimis subcongestis, pedicellatis; petalis acute oblongis, extus rufo-tomentosis, 
intus barbatis; disco alte conico, subangulato, leviter fusco-tomentello, apice rufo- 
tomentoso ; filamentis leviter tomentellis, subreflexis ; ovario trigono, subabscondito ; 
stylo longiusculo exserto. In Brasilia, v. s. in hb. Hook. (Sellow). 
In this species the opposite branches extend at right angles with their axils 4 in. apart ; 
the leaves are 21—3 in. long, 1j-1$ in. broad, on a petiole 21-3 lines long; the panicles 
are 14 in. long, the peduncle being 9 lines in length, the primary branches 5 lines, the 
rest gradually diminishing, so that the flowers become crowded in roundish heads; the 
flower expanded is 3 lines in diameter, on a pedicel 1 line long. The entire pa and 
inflorescence is charged with 1 numerous white spiral threads.
