being  that  the  pedicels  of  the  flowers  are  half  as  long  again  (15 
mm.),  and  that  the  leaflets  are  always  glabrous ;  but  the  fruits  met 
with  in  the  Paraguay  jaborandi  of  commerce  never  have  pedicels  so 
long.  The  Paraguay  jaborandi  of  commerce  is,  however,  not  uni- 
form. There  appears  also  to  be  two  species  cultivated  at  Kew  under 
the  name  of  P.  pennatifolius.  The  several  species  found  in  Paraguay, 
and  bearing  purple  flowers,  require  a  more  careful  examination  at 
the  hands  of  local  botanists. 
(4)  Maranham,  or  Small  Jaborandi. — In  1893,  Mr.  T.  Wardle- 
worth  described  another  kind  of  jaborandi,  which  had  been  im- 
ported into  Liverpool.  This  proved  to  be  a  new  species,  and  was 
appropriately  named  by  Dr.  Stapf,  Pilocarpus  microphyllus,  as  it  has 
the  smallest  leaves  of  any  known  pilocarpus.  The  leaflets  yielded 
to  Mr.  Conroy  an  alkaloid  possessing  all  the  chemical  properties  of 
pilocarpine.  Mons.  A.  Petit  obtained  0-5  per  cent,  of  nitrate  of 
pilocarpine. 
(5)  Ceara  Jaborandi. — In  1894,  specimens  of  a  new  jaborandi 
were  received.  The  upper  surface  of  the  leaflets  is  a  dark  brownish 
green,  and  the  lower  a  yellowish  tint,  and  covered  with  short  curved 
hairs.  They  are  smaller  than  P.  pennatifolius  and  have  recurved 
margins.  The  fruit  is  short  pedicelled  and  characterized  by  warty 
ridges  on  the  back  of  the  carpels.  The  leaves  have  only  two  pairs 
of  leaflets.  The  leaves  yielded  only  02  per  cent,  of  crystalline 
nitrate.  Mr.  Holmes  has  named  this  species  Pilocarpus  trachylo- 
phus. 
(6)  Aracati  Jaborandi. — This  is  evidently  from  one  of  the  sim- 
ple-leaved species,  probably  from  P.  spicatus,  A.  St.  Hil.,  and  is  the 
first  appearance  of  other  than  the  pinnate-leaved  species  in  com- 
merce. The  leaves  are  about  the  size  and  very  like  in  shape  to 
those  of  Laurus  nobilis.  The  upper  surface  is  polished  and  the 
veins  scarcely  visible ;  on  the  under  surface  they  are  more  visible, 
but  are  very  slender.  The  texture  is  papery,  but  rather  rigid,  brit- 
tle, of  a  dark  brownish  green  above,  and  of  a  rather  pale  hue  be- 
neath. The  purely  lanceolate  outline  and  the  short  twisted  petiole 
readily  distinguish  it,  whilst  the  pieces  of  twig  attached  show  that 
it  is  a  simple-leaved  species.  Mons.  A.  Petit  was  unable  to  find 
pilocarpine  in  them,  although  he  found  a  small  quantity  of  another 
alkaloid.
