South .'Africa- Locality and collector unknov/n. In cultivation 

 in 1714 according to Alton. 



Although this is one of the oldest known species of the genus 

 and still in cultivation, there anpears to be no record of its re- 

 discovery since the time when ^ilJ.enius described and figured it in 

 1732. It is nearly allied ton G. fragrans, but is easily distinguished 

 from that and all others by the very sharp, knife-like urper edge 

 of the leaves, esi^ecially o-f the larger leaf of each pair, and the 

 absence o-f* raised, transversely-elongated surface cells, such as ex- 

 ist on Gr. -^ra grans as seen when viewed with a strong lens. ^^ig. 8 

 is made from a living plant,

14 of its life, sometimes on South African plants only 9-20 lines long, 

 6-11 lines broad and 4|--6 lines thick, ovate or roundish- vate,

 beneath, nerrov^ring from about an inch belov/ the aoex to a rounded 



or blunt point, v/hich in the longer of each pair is produced beyond 

 the flat or concave face; sometimes v/here the flattened part ends
