The specimen is in young flower and without the lower stem and leaves. It is 

 probably specitically separable from 31. suhcomposifa, as the very long style-bi*anches 

 here present could hardly become short in fruit.

One of G. Mann's examples has the brarts sessile and truncate at the base, the 

 other has tlie bracts long attenuate and quasi-peiioled. These may represent two 

 distinct species ; hut G. Mann has numbered both 1639.
