46 



member of the Cistaceae or Rockrose Family, was discovered 

 with its flat rosette of reddish green, quarter inch, persistent 

 leaves. 



Various species of Broom Grasses as Andropogon scoparius 

 and A . virginicus in dry sandy fields and A . corymbosus abbrevi- 

 ates of swamps were still in a condition for identification. The 

 first two cover more or less completely all abandoned fields in 

 the Barrens before they are taken over by the Pitch Pine- 

 scrub oak growth and line all the sand roads for miles on end.

March 24, 1935 — Parker Cabin Mountain, 

 Palisades Interstate Park 



Despite the pessimistic predictions of the weather bureau, 

 the day dawned clear and fine. Eleven members and guests 

 turned up for this trip to observe the lichens of the Highlands 

 of the Hudson. Starting at Tuxedo, the party climbed Black 

 Ash and Parker Cabin mountains, observing many common 

 species as they went. 



The Brownie's Buttons (Biatorella claims) was especially 

 common on the granite-gneisses of the hills. Only the small 

 black disc of the fruit is visible to the naked eye, the rest of the 

 lichen being hidden within the rock. Rock tripes (Umbilicaria 

 pustulata and Gyrophora dillenii) were common, especially on 

 the exposed rocks at the higher levels. Less conspicuous were 

 the crustose Lecidea albocaerulescens and Lecanora cinerea. 



At the tops of the hills was a characteristic lichen flora. 

 Cladonia rangiferina, the reindeer "moss" was intermixed with 

 Cladonia uncialis among the Hairy cap mosses at the edge of 

 the exposed rock surfaces. The former was easily distinguished 

 among the others by its ashy gray color. Here too, especially on 

 the sandstone and quartzite boulders left by the glaciers, was 

 Rhinodina oreina, a crustose yellow-green lichen with lobed 

 thallus. Although fairly common at the higher levels in this 

 vicinity, it is only occasionally found at sea level. Lecanora 

 tartarea, the "cudbear" which the Scotch use in making a dye, 

 was found fruiting abundantly.
