surface  of  the  ieaves  covered  with  a  dense  velvety  pubescence  composed 
of  simple  hairs.  The  hairs  are  not  so  numerous  on  the  leaves  and 
lower  part  of  the  stems,  but  appear  to  be  singularly  persistent,  as  they 
mav  be  found  on  the  bark  for  a  considerable  distance  down  the  stem 
when  it  is  examined  wich  a  lens.  In  shape  and  size  the  leaves  resem- 
ble those  above  described,  but  are  rather  thinner  in  texture,  and  have  a 
somewhat  different  and  less  pungent  taste.  The  lowest  pair  of  leaflets 
in  the  specimens  I  have  examined  are. only  two  to  three  inches  from  the 
base  of  the  rachis.  I  have  not  succeeded  in  finding  entirely  glabrous 
leaves  on  the  stems  which  have  hairy  leaves,  nor  hairy  leaves  on  the 
stems  which  have  smooth  leaves,  and  therefore  consider  that  the  plant 
with  hairy  leaves  is  probably  a  distinct  variety. 
The  inflorescence  is  a  raceme,  six  or  eight  inches  long,  judging  from 
the  peduncle  figured  on  p.  175.  The  base  of  the  peduncle  there  rep- 
resented is  entire,  but  the  top  is  evidently  broken  off,  so  that  it  may 
have  been  one  or  two  inches  longer.  The  pedicels,  so  far  as  can  be 
learned  from  the  scars  on  the  peduncle,  are  numerous  and  about  three^ 
eighths  of  an  inch  apart.  Whether  they  are  horizontal  or  not  when 
flowering  it  is  impossible  to  say.  The  only  two  specimens  I  have  seen 
are  in  fruit  and  have  the  pedicel  deflexed  and  about  half  an  inch  long,, 
The  fruit,  fig.  3,  closely  resembles  in  external  appearance  that  of  a 
specimen  of  a  Cuban  plant  in  the  British  Museum,  *  referred  by  Asa 
Gray  to  Pilocarpus  heterophyllus  (PL  Wrightianae,  p.  170  ;  Wright,  1 129.) 
When  perfect  it  consists  of  five  carpels,  of  which  not  more  than 
two  or  three  are  usuallv  developed  to  maturity.  When  ripe  the  carpek 
dehisce  into  two  valves,  as  in  fig.  5,  and  then  remind  one  strongly  of 
miniature  cockle  shells,  fig.  4,  with  the  valves  open  exposing  the  ani- 
mals. 
This  appearance  is  owing  to  the  fact  that,  as  in  two  or  three  other 
closely  allied  genera,  the  endocarp  separates  at  a  very  early  stage,  and 
thus  forms  an  inner  case  for  the  seed,  as  represented  in  figs.  5  and  7. 
The  outer  portion  of  the  carpel,  consisting  of  the  united  epicarp  and 
mesocarp,  is  in  most  of  the  specimens  of  a  pale  brown  or  buff  color, 
coriaceous,  convex  on  both  sides,  of  a  somewhat  circular  form,  but 
with  the  inner  edge  (/'.  f.,  that  nearest  to  the  stigma)  nearly  straight, 
marked  both  inside  (fig.  6)  and  outside  (fig.  4)  with  curved  ridges,  which 
*  The  genus  Galipea^  to  which  P.  heterophyllus  has  been  referred,  is  distinguished 
IVom  Pilocarpus  by  the  convolute  cotyledons,  tubular  flowers,  and  anthers  not  vers- 
atile.
