apply to the plant figured by Beddome,' which is very distinct. It has 

 naked indusia, broader than long, usually cordate, and with free sides. 



ANGIOPTERIS MADAGASCAR! ENSIS De Vriese. 



Madagascar, Humblot 5U6. 



De Vriese 4 concludes his description with "An fortasee potius evolu- 

 tionis status?" That his specimen was decidedly immature is shown by 

 several of his notes; especially, "Sori . . . nigri, propter indusium quo 

 teguntur, haud bene conspiciendi." The character on which he lays most 

 emphasis, the very thin and pellucid pinnule, depends on the immaturity. 

 Humblot's specimen is mature, and permits the following corrections to 

 be made in the description: 



Rachis pale brown and, like the costa, nearly naked; pinnules up to 

 20 cm long, lanceolate, dentate with moderately serrate tip, papyraceous, 

 subpellucid, veins opaque, conspicuous, false veins present, but incon- 

 spicuous and reaching less than halfway to the costa; sori 2 mm from the 

 margin, 1.5 to 2 mm long, deep brown, on the outside almost black because 

 of the dried and adherent indusium, of which there are no loose fragments; 

 sporangia 10 to 15, or rarely 18. The pinnules are rather long-stalked 

 (3 mm) ; the lowest has a stalk 2 cm long, and bears 2 free leaflets on the 

 lower side — as sometimes observed in other species with very ample 

 fronds. As these deviations from De Vriese's description are all such as 

 a mature frond could be expected to show in comparison with an immature 

 one, I have no doubt that the plants are the same.

This has the form of a very small E. decurrens, but utterly different
