M. G. Price, who has seen living plants on Mt Makiling, regards this as a distinct species, in frond-form between T. decurrens and T. crenata. It differs from the former in the firmer texture of the narrow rachis-wing which extends only a short distance below the lowest lobes of the lamina, in the more numerous and closer lamina-lobes, darker stipe and rachis and broad stipe-scales. The type of T. loheri Copel., though consisting of an almost complete frond, is imperfectly developed; that of T. sulitii is much better and is therefore preferred; they were published simultaneously. There may be intermediates between T. sulitii and T. crenata.
