In  ]\Iartinique  the  young  bark  is  used  to  clarify  sugar,  for  which  the  copious  mucilage
it  yields  when  macerated  quahfies  it.  In  the  same  island  the  infusion  of  the  old  bark  is
esteemed  as  a  sudorific,  and  useful  in  cutaneous  diseases.  The  bark  of  Kydia  calycina  is
applied  in  India  to  the  same  purpose.  The  fibrous  tissue  of  the  bark  of  many  species
is  so  tough  as  to  be  well  adapted  for  manufacturing  into  cordage  ;  tins  is  more  especially
the  case^mth  ]\Iicrol£ena  spectabiUs,  and  Abroma  augustum.  The  bark  of  Dombeya
spectabihs  is  made  into  ropes  in  Madagascar.    The  Pterospermums  are  all  mucilaginous.
