"10471.  Sev11-  specimens  of  the  Pareira  Brava,  from  Lisbon, 
accounted  a  great  remedy  in  suppression  of  water  and  the  stone, — 
according  to  Monsr-  Geoffroy,  the  Ambitua  or  Butua  of  Zanoni. — 
From  Dr.  Fuller,  Sevenoaks." 
In  1866,  I  applied  to  my  friend  Theodor  Peckolt,  druggist,  of  Rio 
de  Janeiro,  then  residing  at  Cantagallo,  in  the  same  province,  on  the 
subject  of  Pareira  Brava,  in  consequence  of  which  I  received  from 
him  specimens  of  two  plants,  the  one  marked  Butua  or  Pareira  Brava 
legitima,  the  other  Butinha  or  Pareira  Brava  miuda  (literally  small 
Pareira  Brava),  together  with  a  large  dried  entire  plant  of  the  former. 
The  herbarium  specimens  of  these  plants  presented  no  characters  by 
which  I  could  distinguish  them  as  two  species;  and  Mr.  Peckolt  sub- 
sequently informed  me  that  their  difference  consists  chiefly  in  habit, 
and  that  the  first  or  legitimate  Pareira  Brava  is  found  in  much  drier 
situations  than  the  small  sort,  or  Pareira  Brava  miuda. 
I  have  also  received  specimens  from  my  friend  Mr.  J.  Correa  de 
Mello  of  Campinas,  marked  Parreira  Brava  pequena  (small  Pareira 
Brava)  or  Abuta  pequena,  and  others  labelled  .Leaves  of  the  plant 
producing  Pareira  Brava,  all  of  which  seem  referable  to  Mr.  Peckolt's 
plant.  Mr.  Correa  de  Mello  has  likewise  sent  me  the  dried  root,  and 
I  have  also  received  the  root  as  supplied  by  a  drug  house  of  Rio  de 
Janeiro. 
Within  the  last  few  weeks  two  specimens  of  roots  bearing  some 
leaves,  marked  respectively  Pareira  Brava,  large  leaf,  and  Pareira 
Brava,  small  leaf,  have  been  presented  to  the  Pharmaceutical  Society 
as  well  as  to  myself  by  Mr.  G.  B.  Francis,  of  the  firm  of  Hearon, 
Squire  and  Francis.  Between  these  two  sorts  I  fail  to  recognize  any 
difference. 
The  roots  of  Mr.  Peckolt's  Pareira  Brava  legitima,  those  sent  me 
by  Mr.  Correa  de  Mello,  and  those  received  from  Mr.  Francis,  com- 
pletely agree  with  Sloane's  specimens,  as  well  as  with  Pomet's  figure. 
As  to  the  plant,  I  identify  it  with  Chondodendron*  tomentosum  of 
Ruiz  et  Pavon,  with  an  authentic  specimen  of  which  in  the  herbarium 
of  the  British  Museum  I  have  compared  it.  It  is  the  Oocculus  Chon- 
dodendron of  De  Candolle  (Prod.  I.  98),  and  has  been  figured  as  Coo- 
*  Mr.  Miers  (Contributions  to  Botany,  III.,  307)  contends  for  this  name  be- 
ing written  Chondrodendron  as  more  in  accordance  with  its  derivation  from 
X<rvfy°<.  But  I  think  it  safer  to  retain  the  original  spelling  as  accepted  by  all 
botanists.
