LL— ECHIUMS FROM THE ATLANTIC 



ISLANDS : IL 



T. A. Sphague, 



(with plates.) 



The Echiuins of the Canary Islands and Madeira were arranged 

 by Christ* in four Series, SimpUcia, Virescentiaj Gigantea^ 

 Strictay according to whether the stem was simple or branched, 

 and to the nature of the inflorescence. De Coincy^t on the other 

 hand, used the annulus inside the corolla and the indumentum as 

 the basis of his classification, and placed side by side species which 

 differ greatly in habit. 



Christ's divisions seem to be more natural, and are adopted as 

 the basis of the provisional classification given below. E, calli- 

 thyrsum has a branched stem, J and is therefore transferred from 

 the Simplicia to the Virescentta.
