 gradually tapering to about 1;^ lin. in diam. at the base of the lobes, 

 glabrous ; lobes erect, cohering at the tips, 8 J lin. long, linear-spathulate

 f lin. below the mouth of the tube, and in the bud form 5 short, blunt, 

 deflexed spurs), replicate throughout their length, fringed with rather 

 long hairs in the lower part, blackish at the mouth of the tube and 

 base of the lobes, shading into blackish-green or dark dull green in

 shortly erect.

 corona, and the processes described may possibly belong to the inner corona.
