 uary, 1899, Snodgrass & Heller, no. 910 (bb. Gr.) ; mountain east of 

 Tagus Cove, alt. 770 m., Snodgrass & Heller, no. 2o4 (hb. Gr.). 

 Narborough Isl. : abundant in southern part at 600 m. alt., forming

 last specimen is sterile and somewhat doubtful. It has leaves 7 cm.

S. microcephala is well marked among its congeners by its small and 

 more numerous heads, also by the presence of an abortive pappus. 

 These features, however, in the presence of an otherwise close resem- 

 blance to the genus Scalesia do not appear to form any good ground 

 for generic separation.
