A novelty of the section Aspidoghssum (E. Mey.) Schltr., which 

 seems to be nearest allied to 8. fasciculare Schltr., but may be 

 recognized by the stronger growtli, broader leaves, different indu- 

 mentum of the stem, leaves, and flowers, and a distinct corona ; 

 remarkable in the genus for the presence of a second row of scales, 

 which, although very small, are distinctly alternate to the outer 

 corona. The first specimens of this species were sent to me by 

 Mr. Wood, but, as they are not at present at hand, I am unable to 

 mention a more exact locality or Mr. Wood's number. The 

 description was made from a specimen collected by myself near 

 Ixopo, also in Natal.
