K. Wu from the same locality in 1962.  To our great surprise, however, this distinct taxon reveals a number of important morphological characteristics intermediate between An- giopteris and Archangiopteris as diagnosed above.   The present species resembles Archangiopteris in small build with creeping dorsi- ventral rhizome, unigeniculate, thin, smooth stipe in pinnate to bipinnatifid fronds, spa- ringly clad in linear-lanceolate peltately affixed scales with variously fimbriate margin, lamina 1—2 pinnate or subbipinnate, pinnules distinctly and shortly stipitate, base cuneate or broadly cuneate, sori of different length separated from each other by broad spaces, and rather far away (2—3 mm) from the margin, paraphyses few, rudimentary and short, but, on the other hand, it also similar to Angiopteris in usually bipinnate fronds, the petiole of pinnae with swollen base (blackish upon drying), short (2—4 mm long) linear sori consisting of 5—16 pairs of sporangia and globulax spores with densely tubucular sporoderms.  All the above characteristics combined clearly indicate the spe- cies is in all likelihood a natural hybrid between  Angiopteris  and Archangiopteris, pending cytological investigation and the reason for presently placing it in Angiopteris rather than in Archangiopteris is because of the fact that in overall impression the newtaxon appears more like the former than the latter.Decontaminated thianthrene disproportion.
