146 FLORA OF LOWER COAL MEASURES OF MISSOURL 



But little appears to have been added to our knowledge of this inter- 

 esting and relatively well-known species since the preparation of the review 

 of its status in my report on the flora of the outlying Carboniferous basins 

 of southwestern Missouri.^ 



Both stems and branches (Annularia ramosd) of this species are not 

 rare in the collections. The examples from Owen's bank and Deepwater 

 seem to present the general characters of the species, though the branch 

 scars, of which there is one at nearly every node, are usually small, and are 

 occasionally accompanied by still smaller cicatrices at some of the joints. 

 The thin scale of carbonaceous matter shows the woody zone to have 

 been thin. The fluting, which appeal's less distinct on the outside of the 

 carbonaceous residue, is nearly obliterated from the cast of the pith in sev- 

 eral greatly compressed specimens. It should be remarked that the ribs, 

 which are rather less sharply defined than iisual in this species, are finely 

 striate throughout.
