Some of the native tufts of this species must be very old, 

 as upon countin^:: the number of sheaths upon a short measured len- 

 gth of one of the stems this species forms, I found that at a 

 rou^h estimate that particular plant was at least one hundred 

 yeers old. '^e p;ro' ths form only one sheeth each year under nat- 

 iirpl conditions.
