Embryos of Angiopteris and Kaulfussia.—In connection with a study of 
these two genera, CAMPBELL” has presented the embryo-formatiop of Marattia- 
ceae. He thinks it probable that in all cases the stem, leaf, and root are epi- 
basal in origin. In Danaea the primary hypobasal cell forms a suspensor, so 
that the foot also is epibasal; and in Kaulfussia and Angiopteris the foot is 
also partly epibasal in origin. The root arises endogenously as a secondary 
structure, and in its growth almost obliterates the foot, which is very large in 
the young embryo.—J. M. C 
Anatomy of Calamostachys.—HICKLING” has studied new sections of C. 
Binneyana, and has come to the conclusion that the so-called fertile or spo- 
rangiophore-bearing “‘nodes’”’ are not nodes in the same sense as the bract- 
earing nodes. He shows that the sporangiophore trace arises from the node 
that supplies the whorl of bracts below, and he believes this to be a general 
characteristic of calamitean strobili, the point of insertion of the sporangio- 
phores on the internode being very variable.—J. M. C.
