FIGURE 71.—Lepturidium insulare. Plant, X 44; spikelet and floret, X 10 (type). 
No pistils have been found in the specimens examined. The 
species may be dioecious. On one specimen (no. 12155), there is an 
auriculate extension of the margin of the rachis below many of the 
spikelets, forming a glumelike point by the side of the spikelet. 
This appears to be an abnormality. In aspect the sterile plants 
somewhat resemble those of Cenchrus distichophyllus.
