phroditum semel observatum, noLis videtur vera Gynmanthis species, fasciculo florum diandrorum ab 

 auctore pro flore unico polyandro descripto. Filaments ssepius a basi libera, cujusve flons tix 

 distinct, iiiterdum tamen per paria ph;8 minus coalita sunt, et in fasciculis nonnuUis magis evolutis 

 bractea 2-glandulosa sub pare adest. Flos henuaphroditus a Muellero Prod. p. 1225 descriptus 

 est forte fasciculus florum magis evulutus flore centrali fcemiueo.
