An abundant quantity of material enabled us to study a 
number of remarkable disturbances of the flower. In order to 
give a proper idea of these we first call attention to fig. 6: the 
calyx is only slightly disturbed, whereas the corolla remains 
very small and scarcely differentiated. The stamens show them- 
selves rather normal, but the pistil is broad and distinctly 
stalked '). No style, but the ovary bent towards the ventral 
suture, the latter being split up and thus opening the ovary. 
Instead of ovules we found small, green, veined lobes or teeth. 
The parts of the flower haying been removed the lengthened 
torus is seen about halfway upward to end in a bud(b), which 
with special distinctness shows the lateral position of the pistil. 
A closer examination of the stamens shows that some of them 
tend to petalize the anther or to produce an appendage under 
the same. The most striking phenomenon is, however, the appear- 
ance inside the whorl of stamens of a row of small buds, 
which as we shall see immediately, foretells an avillary foliar 
prolification. 
When examining the flowers higher up the inflorescence we 
saw that the disturbance works more intensely: apart from the 
calyx which hardly shows further alteration, the corolla gradu- 
ally falls off finally to disappear altogether, the stamens are 
shorter and scantier, while on the other hand the buds grow 
stronger and finally become short branchlets with trifoliolate 
leaves (axillary foliar prolification). 
But also the torus lengthens and produces a number of 
»lowers” of which the bracts are much more developed than 
the minute flowerbuds which they subtend and cover (terminal 
floral prolification). On the rest of the general peduncle the
