Conard says ‘the American plant, from its small nuinber of 
stamens and their insertion below the summit of the torus, may

Conard shows that Walter’s diagnosis cannot wholly apply 
to this plant, and no specimens exhist in the Walter herbarium. 
“Loculis monospermis”” applies to Neluméo, and Rafinesque so 
understood it. Conard calls this plant M. odorata gigantea 
_Tricker, 1897, but cites much earlier names.
