29. Leda, C. B. Clarke [Leptostachya, Nees, partim] . 

 Herbs. Panicle loose ; branches long, linear, with distant flowers 

 solitary or in clusters in the typical form ; bracts inconspicuous. 

 Stamens 2 ; anther-cells 2, the lower without a tail, at equal height 

 parallel, or one lower somewhat divaricate ; pollen ellipsoid, with 2 

 stopples, the longitudinal rows of patches on either side of each stopple 

 prominent or obsolete. Otherwise as Justicia, Sect. Gendarussa. — • 

 DisTRiB. Species 12, in South-east Asia. 



The seventy American species, among which stands Dianthera, Linn., differ 

 greatly in habit among themselves and from the Indian. The genus Dianthera is 

 sunk in Justicia by Lindau in Engl. & Prantl Pflanzenfam. IV. 3 b, 346, which 

 then has three hundred species and is inconveniently large. But the Indian 

 Dianthera only differs from Justicia vasctdosa, Wallich, and its neighbours by the 

 absence of a white tail to the lower anther-cell.
