cles. Conceptacles sessile, truncato-conical, crowned with about four short 

 horns or tubercles. Teti'aspores cruciate, abundant in the periphery of the 

 subulate rarauli. The colour is a pale, sometimes a very pale, rather dull 

 red, somewhat brownish in the stronger specimens. Substance at first ra- 

 ther crisp, soon becoming flaccid in the air, soft and juicy. In drying the 

 frond adheres closely to paper. 



At Plate LXVII. is figured the original species on wliich the 

 genus Horca was founded : and two others are figured in the 

 ' Mora of Tasmania.' Our present Plate represents still another, 

 and the only other known species. It is the least expanded, and 

 the most shrub-like of the genus, but agrees with all the rest in 

 fruit and structure. 



There is greater diversity between the individuals that bear 

 the different fruits in this than in the other species : those that 

 bear conceptacles having a stunted growth, and much more ir- 

 regular and more divided ramification.
