50 feet. The type specimen is in my private herbarium. 



This species is remarkable for the caudate upper portion of the 

 inflorescence, no other species known to me approaching it in this 

 respect. The divisions of the perianth are also unusually narrow. 

 The plants are gregarious in habit, a dozen or two of them usually 

 growing in proximity.
