Dr. Hooker merely recalls attention to the essential facts that these plants — 
exhibit true flowers with stamens and pistils, genuine ovules, and even em- 
ryo, and so accord in no one particulan with Cryptogams. He shows 
moreover that the embryo is dicotyledonous in the few cases where it is 
sufficiently developed to manifest the character, and that the stem is con- 
structed upon the exogenous plan. Even with these facts before him 
Lindley has retained his Rhizogens, as “ logically a class ;” as an interme 
diate form of organization between Hndogens and Thaillogens, and chat- 
acterized by vegetation rather than fructification. But there is little or 
are not founded upon degradation of type, but upon change of type. 
Viewing Balunophorca, then, as degraded members of the Dicotyledo- 
conceive of Gunnera with its minute embryo as a reduced Pa 
while it is impossible to sever the chain of evidence which binds the genus 
the 
od 
eous has them in Monotropee ; a 
degrades through Santalacee into Loranthacea. 
It is quite probable that our author would deny the degradation in ae 
latter case, judging from some points which he makes when consicernd 
whether the group of Balanophorea, “ putting aside any consideration © 
its relationship with other orders, and regarding it per 8, 6s: should 
abstractedly be considered as ranking high, or the contrary.” This is #?
