1. S Triandra, Dalz. in Hook. Jour. Bot. ii, 144. — Root 

 fibrous ; leaves long-petioled, linear-spathulate, 3-nerved, much 

 longer than the scape, obtusely keeled on the back ; scape erect, 

 simple, round, obtusely trigonal at the apex ; flowers triandrous, 

 verticelled, shortly-pedicelled, inconspicuous ; female flowers on the 

 lower part of the spike. In water-holes, Malwan Talooka ; flowers 

 in August.
