* Seven individuals were added to the marked plant sample set in 

 1991. 



** A plant mapped as two individuals in 1991 was remapped as one 

 individual in 1992; the 1991 numiber was decreased accordingly. 



*** All fruiting plants at Horse Praire were browsed in 1992; 

 only aborted fruits were produced. 



**** Plant /8 among the permanently marked plants was recorded as 

 dead in 1991 and alive in 1992; it was excluded from mortality 

 figures. This is the only reported incidence of dormancy, and 

 may reflect a misinterpretation or a new plant establishing in 

 the same place as the old one.
