 both ends ; panicles ovate ; spikelets usually simple. J? . G. 

 Native of the Canary Islands. Lehm. asper. p. 418. This very- 

 distinct species is difficult to characterize : the calyxes in the 

 terminal panicles are equal in length to the corollas, but those in 

 all the lateral panicles are not one half the length of the corolla, 

 hence the specific name. Corolla white, fading to red.
