 Ist 1912 and the additions which could not be inserted in the 

 first part of this publication, when in the press.

When the manuscript of this Bulletin was in the press we 

 received on loan from the RIJKSHERBARIUM in Leiclen {Holland) 

 a spécimen of L. pumila BL — The fronds agrée in ail parts with 

 Blume's coloured plate quoted above except that the sori are 

 more round. The pinnae are suberecto-patent, with the soriferous 

 lobes neither compressed nor twisted, turned back on the upper 

 surface of the frond, and the sori therefore facing upwards. — L. 

 "philippinensis v. A. v. R. differs from this in having the pinnae 

 nearly horizontal, with the soriferous lobes horizontally spreading, 

 laterally compressed, twisted, and the sori facing towards the 

 apices of the pinnae.

 crassae; venae latérales adsunt, liberi. Sori lineares, utrinque 1, 

 costae paralleli, parenchymate costali inferiori valde producto

Sori linear, 1 on each side, parallel to the costa, immersed in 

 relatively deep submarginal or intramarginal grooves, i.e. protected 

 by the much produced (widened and thickened) costal paren- 

 chyma which is sometimes nearly as broad as the lamina, so 

 as to form the common inner wall to both soral grooves, the 

 fructiferous région of the frond therefore conspicuously thick,
