HALECIID^E. 



Fig. 27. 



capsules should be absent. Its mode of growth is lax and 

 irregular, and contrasts strongly with the stiff and erect 

 habit of its ally ; its stems are not so stout, and the 

 texture is more delicate. The annulation of the branches 

 which is often very strongly marked, and the form of the 

 deep, somewhat campanulate calycle, with its elegantly 

 everted margin, are good distinctive signs. The purplish 

 colour, too, seems to be a constant character in fresh speci- 

 mens. 



The male capsules only have been described by Mr. 

 Alder. I am indebted to Mr. Peach 

 for very fine specimens from Wick, 

 bearing the females in abundance. 

 (Woodcut, fig. 27.) 



As in the other species of this genus, 

 the calycles are often composite, seve- 

 ral cups rising one within the other 

 and registering, as it were, the number 

 of polypites that have budded succes- 

 sively and perished. 



H. labrosum is commonly between 

 3 and 4 inches high, but occasionally 

 reaches 6 inches.
