 A   considerable  number  o f   plants  o f  th is  Order  inhabit Australia,  bu t  ow in g   to   the  rapid  fading  o f  the  
 corolla  o f   many  o f  the   tropical  species,  th ey  have  been  either  n eg le cted   or  preserved  in   a   state  unfit  for  
 e x amination;  thu s,  o f  fifty-three  species  described  in   Brown’s  ‘ Prodromus,’  many,  especially o f  Ipomoea  and  
 Convolvulus,  are  unknown  to  us ;  and  o f  about an  equal  number  o f wbich we   have  specimens,  there  are  not  
 a  few  that  are  undeterminable,  partly  owing  to  the  briefness  o f  the   diagnoses  in   th e   ‘ P rodromus,’  and  
 partly to  the specimens  b e in g   in  an imperfect  state.  Probably there are about six ty  known Australian species,  
 by  far  the   greater  majority  o f  which  are  tropical,  and  some  o f  them  common  to   many  parts  o f  th e   globe.  
 Am on gst  the   most  conspicuous  o f  these  are  th e   C a ly steg ia   Sepium  and  S oldan e lla,  which  are  found  in   
 almost  all  temperate  r egions  o f  both  th e   northern and  southern hemispheres ;  Ci-essa  Crética, D ichondra  re p 
 e n s ,  and  several  species  o f E vo lvu lu s,  which  inhabit mauy  tropical  countries  o f  th e  Old  and  N ew   YYorld;  
 aud  lastly,  various  species  o f  P h a rb itis ,  Ipomoea,  and  B a ta ta s ,  which  are  common  E a s t  In d ian   and  P o ly nesian  
 plants.  Altoge th e r,  fully  one-third  o f  th e  Australian  Convolvulaceæ  are  fouud  in   other  parts  o f  the  
 g lo b e ;  and  one  genus  alone,  W ilsonia,  is  confined  to   th a t  con tin en t  and  Tasmania,  and  to  th e   south  
 and  especially  south-we st  coast.
