110 THE JOURNAL OF BOTANY 



De Wildeman {I. c.) publishes this as " Gnidia Bucliananil 

 Gilg," a plant which it resembles superficially. The smaller heads 

 and tiny flowers enable one to distinguish the new plant at first 

 sight, irrespective of the absence of scales from the mouth of the 

 calyx. The affinity is with A. polycephala C. A. Mey.

To be inserted in the genus next to A. pleiirocephola H. H. W. 

 Pearson, a species not represented in this country, but described as 

 having ovate-lanceolate involucral bracts and heads with 5-6 brown 

 flowers.

Planta trispitharaea habitu scopario. Folia ±10 X "5 mm., in 

 sicco viridi-brunnea. Capitula pansa modo 5x3 mm. ; horum

Like the last, this is allied to A. pletiroccpliala : it differs from 

 A. microcepliala mainly in the involucres and the flowers.
