A few annuals occur, such as Silono antlrrhlna L*, (sleepy 
catchfly), KrIgoron canadensis L. (horse-weed), and Poly ¬ 
gonum Pouglasll Greene. These annuals lead a precarious 
existence, as their seeds must, in tho main, bo washed 
over the cliff each year* The distribution of the above 
herbaooous species varies considerably from one point of 
the ridge to another. Their presence results in the 
accumulation of humus, especially in depressions or in 
connection with dead mats of Solaginella* 
Accompanying the herbaceous vegetation are a few 
speoies of low shrubs, the commonest being species of 
blueberry ( Yaceiniun ponnsylvanioura Lam. var. angustl - 
folium (idt«) Gray and Vaooiniuci nigrum Britton). These 
often form largo patches slightly bach of the summit, 
where more soil has accumulated. Other spocios found 
along the summit are:- Juniporus oonmunis L. var. nontana 
Ait., Bosa aclcularis Lindl., Sails humulls Marsh., Dior -
