* J. Sphagni and J. comprtssa, if the young shoots alone are examined, will be seen to possess small stipules; 
but, as I never could find them on the older stems, I have thought it best to place them in the division Exstipulatce. 
p This species has the leaves very indistinctly divided ; yet, I think, it cannot enter into any other family than 
the present. 
j j, capitata has the leaves sometimes, though rarely, bifid, and it might be looked for in the following tribe.
