 Foerste states in the Botanical Gazette for 1892 that vas- 

 cular strands are found beneath the usual position of the 

 larger prickles of Xanthoxylum even when these are aborted. 

 Specialized outgrowths from a plant member are sometimes 

 distinguished under the name emergences, particularly when 

 they contain vascular elements.
