Qualitative collections were made over an area sufficiently wide to characterize the flora at each site. 

 Samples were identified fresh, or after short-term freezing. Voucher specimens were preserved using various 

 methods, depending on the material: in 4% formaljn/seawater, as dried herbarium mounts, or on micro- 

 scope slides. 



The Millstone quarry study was initiated in 1982. One site at the original quarry cut (site I, Fig. 3) 

 and three sites within the quarry (sites 2-4) were sampled monthly to permit examination of species 

 composition under greater than ambient water temperatures. The quarry samples were processed as 

 described for the qualitative collections from the rocky intertidal stations.
