Of the typical A.filiformis T have seen no tropical .si)ecinien.s, but it is nieutioni-d 

 by Schinz as occurring in Hereroland, It would seem likely to be useful as a 

 tibre-plant, as Mrs. Barber states on a note sent with some South African specimens 

 " This species ougl.t to be useful as a fibre-plant, it is exceedingly tough, grow.s 4-6 

 ft. liigh, and h)S upwards of two hundred almost leafless slender steins on a single 

 plant." 



Tlie variety buchenaviana seems only to differ in its stouter, branched stems, as 



1 doubt if the coronal characters are constant, since tliere are specinuns at Kew 

 collected in Great Namaqnaland by Schinz (19), that have tlie stout branched .stems 

 of this variety, but with coronal-lobes as in the type.
