Leone  copal,  and  is  produced  by  Guibourtia  copallifera,  Bennett,  Kobo  of 
the  natives  ;  specimens  of  this  tree,  including  the  ripe  pods,  are  requested  ; 
it  grows  at  Goderich  and  in  other  localities  near  Sierra  Leone. 
Grains  of  Paradise. — Although  Amomum  Melegueta,  Roscoe,  the  plant 
which  yields  this  drug,  is  now  well  known,  there  are  some  other  interest- 
ing species  nearly  allied,  with  which  botanists  are  very  imperfectly  ac- 
quainted. It  is,  therefore,  desirable  to  procure  specimens  of  such  plants 
from  various  parts  of  the  West  Coast  of  Africa.  These  specimens  should 
comprise  the  flowers  and  fruits,  as  well  as  the  foliage.  As  the  flowers 
are  very  delicate,  it  is  necessary  to  preserve  some  specimens  in  spirit  of 
wine  or  in  dilute  acetic  acid.  Some  specimens  of  the  fruits  should  also  be 
preserved  in.  the  same  manner.  As  the  species  often  grow  intermixed,  and 
as  flowers  and  fruits  are  produced  at  different  seasons,  special  care  is  re- 
quisite to  avoid  confusion. 
Korarima  Cardamom  is  the  name  under  which  the  late  Dr.  Pereira  has 
described  an  Abyssinian  cardamom,  having  the  shape  and  size  of  a  small 
fig,  which  is  exported  from  Mussowah,  a  port  at  the  southern  end  of  the 
Red  Sea.  This  drug,  which  has  long  been  known  in  medicine,  is  perfora- 
ted at  the  smaller  end,  and,  when  strung  upon  a  cord,  is  commonly  used 
by  the  Arabs  and  Abyssinians  as  beads  for  their  mesbehas  or  rosaries.  It  is 
said  to  be  brought  to  the  market  of  Baso,  in  Southern  Abyssinia,  from 
Tumhe,  a  country  situated  in  about  9°  N.  lat.  and  35°  E.  long. 
The  plant  for  which  the  name  Amomum  Korarima  has  been  proposed,  is 
entirely  unknown. 
Olibanum. — The  Olibanum  found  in  European  commerce  is  believed  to 
be  produced  partly  on  the  African  coast,  near  Cape  Gardafui,  and  partly 
on  the  southern  coast  of  Arabia,  whence  it  is  shipped  to  Bombay. 
Olibanum  is  also  produced  in  India  by  certain  species  of  Boswellia,  called 
Salai  or  Saleh,  one  of  which  is  B.  glabra,  Roxb.,  another  B.  thurifera, 
Colebr.  It  is  extremely  doubtful  if  the  Olibanum,  afforded  in  India  by 
these  trees,  finds  its  way  to  Europe,  but  information  on  this  point  is  desired. 
African  Olibanum  is  yielded  by  a  tree  called  Plosslea  floribunda,  Endl. 
[Boswellia,  Royle;)  but  as  the  drug  varies  considerably  in  appearance,  it  is 
highly  probable  that  it  is  obtained  from  more  than  one  species.  The  varie- 
ty called  Lubdn  Mattee,  from  its  being  shipped  at  Bunder  Mattee,  is,  for 
instance,  a  very  different  drug  from  ordinary  olibanum. 
A  resident  at  Aden  may  be  able  to  gather  some  information  upon  this 
subject  as  well  as  upon  the  next. 
Myrrh.—  This  celebrated  drug  is  collected  in  great  quantities  by  the 
Somali  tribes  on  the  African  coast,  near  the  southern  extremity  of  the  Red 
Sea,  whence  it  is  brought  to  Aden  for  shipment  to  Bombay. 
A  variety  of  myrrh,  which  is  probably  yielded  by  another  species,  is  also 
produced  (according  to  Vaughan)  in  a  district  lying  forty  miles  to  the  east 
of  Aden,  to  which  place  it  is  brought  for  sale.
