 Stigma 2-fid. Ovary of Rudgea. Berry ovoid, smooth, 2-celled : seeds flat on the inner 

 side. — Shrubs; leaves large, arch-veined: stipules subulate; flowers glomerate in the axils. 



110. R. latifolia, Aubl. Glabrous or pubescent ; leaves elliptical or oblong, pointleted, 

 cuneate at the base : stipules short, with a long, subpersistent mucro ; clusters equalling the 

 petiole or exceeded by it ; corolla-lobes oblong, bluntish, pilose within, one-third as long as
