MR. SPENCER MOOUE : A CONTIUBUTION 



a Cambodian plant, not reaching Australia*. It is interesting to note that 

 our gonusis closely related to the also almost exclusively Australian Loyanm^ 

 the two fijenera contributing more than 90 per cent, of the Natural Order as 

 represented in Australia. Since vol. iv. of the 'Flora Australiensis* 

 appeared in 1809, only three Australian si^ecles seem to have been described, 

 viz, AL palustris^ Fitzg. and two others by the same author; to these may 

 now be added the two which follow.

 gracili spargim ramoso (ramis ascendentibus) subter(iti glabro ; foliu (radi- 

 calibus carentibusj usque ad squamas caulinas minimas ovatas vel ^Liibulatas

 often the case with thie writer, being too fragmentary to bo of any service.
