Obs. — In Herbariums and books there is great confusion 
in the synonymy of what, according to Garden plants, seem 
to be two distinct species ; — • viz., Dictyopteris irregularis and 
T). macrodon of Presl ; judging from Herbarium specimens, they 
are difficult to be recognized as distinct ; but living plants show 
the first to have erect vernation, the other decumbent. 
The Kew Collection is indebted for this species, as also the 
beautiful Microlepia flatyphylla, and others, to Mr. Robert 
Kennedy, Florist and Fern-dealer in Covent Garden.

Obs. — A plant of this Fem was sent some time ago from Old 
Calabar to the Royal Botanic Garden, Edinburgh, and I am 
indebted for a specimen of it to Mr. James McNab, the 
Curator of that truly scientific garden.
