Ibis species ia some measure connects Ponwderris with Trpnaliim, but both the in- 

 floreseence and llowcrs are much more those of the former genus than of Trymalium, espeei:i]]y 

 "they are really apetalons, as I find them in all the specimens I have examined, althou-h 

 l^eissek describes broadly hood-sLapcd petals with slender claws.
