Pelory. The gynostemium shows three lobes, which surround 

 the concave stigma. The topmost lobe is of course a staminode, 

 the two others, which are indented, represent the sides of the 

 clinandrium. (Fig. 37).

The stout flowerstalk normally cilindrical at the lower end, 

 splits up into two at the top. This bifurcation is preceded 

 by a flattening 6 cM. lower and a furrow on either side higher 

 up. At the beginning of the furrows two bracts are found at 

 a distance of 5 mM. between one another. At distances of res- 

 pectively 23 and 27 mM. higher than these bracts there spring 

 from the edges of the stalk two normal flowers, the higher of 

 the two remaining 3 cM. under the bifurcation; the two branches 

 of this bifurcation, 4 and 5^ cM. long, are at almost a straight 

 angle and show — as usual — a zigzagline. Moreover on the point 

 of bifurcation two bracts are to be seen, placed back to back. 

 From the axil of the one bract springs a normal flower, from 

 the other a synanthy consisting of two flowers which along the 

 whole length of the petioles and part of the ovaries have grown 

 together, though deep furrows indicate their limits. For the 

 rest the flowers are normaP). (Fig. 38).
