 Lrptospermum, Jsachne, Drosera, Patersonia, etc. 



While the above specimens differ slightly from the description and fifjiire given 

 1)V S1(ipl\ still 1 can detect no constant characters by which the I'iiilippine form 

 can be distinguished from the Bornean, and without comparison with the type 

 material 1 do not care to describe the Halcon ])lant as a new species. The genus 

 is new lo tlic Pliilipi)ine flora, and its discovery is another link in the chain of 

 evidence regarding possible previous land connections with Borneo on the one 

 hand, and with Australia on the other. Didiscus saniculnefolius was previously 

 known only from iSIount Kinabalu. North Borneo, being related to the Australian 

 D. hum His. Of the genus, about fourteen species are recognized, twelve in Aus-
