676 Bryophyten. — Pteridophyten. 



The second question is, whether floral subprovinces can be 

 established for the rest of the Philippines. There seems to be 

 much difference between the eastern and western provinces, but as 

 some critical areas are yet bryologically inexplored , we must wait 

 the results of further researches. Jongmans.

Campbell, D. B,, The genus Macroglossum Copeland. (The 

 Philippine Journ. Science. C. Botany. IX. p. 219—223. t. 1. 1914.) 



This genus has been described by Copeland from Borneo. 

 A comparison with Angiopteris Srnithii Raciborski shows, that this 

 species also belongs to Macroglossum. The two species of this 

 genus are allied in many respects but can be easily distinguished. 

 A comparison of Macroglossum with Angiopteris shows a number 

 of notable differences. The habit of the plants is quite unlike, as 

 Macroglossum much resembles the larger species of Danaea. The 

 anatomy of the lamina is very different, A striking feature in Ma- 

 croglossutn is the development of a conspicuous ridge separating 

 the elongated sori, so that the latter are sunk in a sort of trough, 

 very much as is the case in Danaea. In M. Alidae only the upper 

 portion of the sporangium is free. In Angiopteris, the sporangia 

 are entirely exposed. 



In Macroglossum there is a conspicuous indusium composed of 

 branching hairs, which form a fringe on either side of the sorus. 

 These indusial hairs are much less developed in Angiopteris. 



The elongated sorus of Macroglossum present a quite different 

 appearance from that of Angiopteris. The individual sporangia are 

 smaller, but much more numerous than in Angiopteris. 



The sporangia of Macroglossum are much less convex dorsally 

 than in Angiopteris, and have an almost flat ventral surface. 



The annulus is much less conspicuous in Macroglossum, and in 

 M. Alidae it is almost entirely wanting. 



There are also slighter differences in the distribution of the 

 tannin cells on the surface of the sporangia. 



The number, arrangement and structure of the sporangia are 

 more like Archangiopteris than like Angiopteris. 



The most obvious difference between M. Alidae and M. Srnithii 

 is in the number of sporangia in the sorus. The sori of M. 

 Alidae contain twice as many sporangia than those of M. Smithii.
