For • :d work it is convenient I 1 ise a small form which is charac- 



terized by slender spinelets typically fairly evenly spared without arrangement in 

 longiseries, or with this arrangement rather vaguely indicated. Then' are usually 

 only two ..r three slender mot Bhort, obovate) carina! spinelets to a plate, mid - 

 feu specimens (including the largest, B ".1 mm., r s mm.) have rather num.
