According to Tison, a third median bundle is usually formed, and in several

Attention will be directed later to the resemblance between the mega- 
sporophyll of Saxegothea and those of other Conifers, such as Athrotaxis i 
in which reduction has undoubtedly taken place. 
Conditions in Microcachrys are very similar to those in Saxegothea , but 
are more simple. The cone-like female strobilus bears numerous fertile 
scales which somewhat resemble the small appressed vegetative leaves and
