The agreement of the above characters establishes not 
a mere analogy, or remote relationship between two orders, as 
botanists have hitherto supposed, but gives to all the genera 
a common ordinal value ; for the herbaceous or semi-shrubby 
mode of growth, presence or absence of tracheids in the tissues 
and of petals in the flowers, the distinct or fused stamens, and 
other points of difference, are not sufficient, and have not been 
made sufficient by systematists hitherto, for the separation of 
genera that otherwise showed decided affinities. 
The following condensed description would enable us to 
diagnose readily from all others an order which might appro- 
priately be termed the Ascidiaceae : — 
Glandular herbs or under-shrubs , inhabiting swamps and
