Apud hotachidem Lyallii et Gunnianam (1. c.) fructificatio ita descri- 

 bitur : 



hotachis Lyallii. — « Perianthio elongato subcylindrico minute tuber- 

 » culato apice obtuso, Ibliis amphigastrioqueinvolucralibus internis minu- 

 )) tissimis, externis majoribus marginibus dorsalibus magis dentatis. » 



Quibus verbis additur : <i It is closely allied to /. madida and to /. Gun- 

 )) nia.na, in the structure ofits perianth, which unlike any other Junger- 

 )) mannia is composed of several layers of cells; this thickening ofits wall 

 w is not owing to the adhésion of the calyptra within, nor to leaves on 

 » the external surface. The inner involucral leaves in ail thèse species are 

 » very minute and liable to be ovcrlooked. n 



hotachis Gunniana. — « Perianthio cylindrico rugoso apice contracto 

 » diaphano. Folia involucralia caulinis similia , interiora minuta et 

 » perianthio appressa. »
