In this plant, as in the Eleusine cruciata, and even indica, the ter- 

 minal florets are frequently abortive ; but they gradually diininisli, 

 ana ppearto have been sterile, because the spike had produced more 

 wus than t could mature. Ths occurs in most spiked grasses, and in 

 manj other plants ; but these abortive flowers are very distinct from 

 J,^ pedicelled neutral floret of the Thloris, (I speak of the C. petraea).
