( T a b . L X X X IX . )
A Guiana Fern discovered by Martin, and which Mr J . Smith has dedicated to his friend
Mr Robert Heward, the friend of the lamented Allan Cunningham, and the inheritor of his
collections. “ In habit,” Mr Smith says, “ it approaches the largest forms of Adiantum and
Schizoloma, agreeing with the first, in the sporangia being produced on the indusium, and
with the latter by the reticulated venation, so that Hewardia bears the same relation to
Adiantum that Schizoloma does to Lindsæa. The reticulated veins of Hewardia and Schizoloma
readily distinguish these two Genera from Adiantum and Lindsæa, in which tlie
veins are all free.”
