The above nd! will I think serve to distingush the plants in 
nearly every case, but it is of course quite artificial, and the only 
satisfactory a ee is to have a close knowledge of certain minor and 
another, but also because some of the species of Rhynchostegium 
are equally hard to separate from them in the absence of fruit.
