"short notes on the plants of the cave hill 

 and neighbourhood." 



On Saturday, 9th April, Mr. N. Carrothers, Secretary of the 

 Botanical Section, read a very interesting paper entitled "Short 

 Notes on the Plants of the Cave Hill and Neighbourhood." The 

 paper, which was illustrated by a particularly fine collection of 

 plants from the vicinity of Cave Hill, contained much useful 

 information regarding the economic and medicinal values of many 

 of the plants, as well as many quaint allusions to old-world beliefs 

 in their magical properties. 



A description of the types of vegetation, found at varying 

 altitudes on the hill, contained many valuable hints as to local 

 opportunities for ecological studies. Among the plants discussed 

 were Lathrim squamaria, Petasites fragrans, AIIiu?n ursinum, 

 Habenaria albida, H. viridis, Pyrola minor, P. media, Orobanche 

 rubra, Sisymbrium Thalianum, Lithospermum officinale, Orchis 

 pyramidalis, and Botrychium Lunaria.
