between the bases of the petioles or axillary, usually consisting of 
slender, simple or branched cymes of flower-clusters or short racemes, 
or occasionally the flower-clusters are sessile at the nodes of the stem; 
flowers usually small. 
Species many, widely distributed in the tropical and subtropical regions of the 
Old World. 
In some species I have failed to find any caudicles to the pollen-masses ; they 
are always very slender. I heve not found the pollen-masses pendulous as repre- 
sented in Engler & Prantl, Pflanzenfam., but frequently their longer axis lies hori- 
zontally in the anther-cell so that half of the mass is above and half below its 
attachment to the caudicle.
