These specimens, in colour and habit, agree very 

 nearly with J. ddvaricata, described by Dr. Taylor as 

 J. exiliflora. May be distinguished by the braided 

 appearance of the leaves, and the margins everywhere 

 recurved. At the base at the outer side they are some- 

 times spiruloso-papillose, but the small teetli of the 

 edges, from their downward direction, often present the 

 same appearance when the papillse are absent. FI. Tas.
