The species belonging to this group develop their fruits, like the Javanici, 

 with protuberances on the keels and sides, for which a disposition can be observed 

 already on the ovaries. As, besides, the styles are also more conspicuous, the 

 ligules stronger, the coriaceous leaves often short-petioled and more roundish-obtuse, 

 and the stem always furnished with numerous cortical strands, but usually no hypo- 

 dermatic layer etc., the group is easily distinguished from the next foregoing. It 

 seems to be a special Australian group, although, interesting enough, a South-American 

 species also, and probably P. mexicanus (= P. montanus Presl?), of Mexico, belong hereto.
