 N a t.  name,  “ Mako-Mako,”   Cunn.  (Cultivated  in  England.) 
 A  handsome  small tree, with large leaves,  generally red or purplish beneath,  and racemes  of small rosy flowers.  
 Leaves  variable in  form,  membranous,  pubescent,  as  are  the  branchlets  and  panicles,  becoming  glabrous when  old ; 
 3 -5   inches  long,  ovate,  cordate  or  oblong  lanceolate,  deeply  and  irregularly  serrate,  acuminate,  on  long  petioles.  
 Panicles,  (though  called  racemosa,  the  inflorescence is  not a  simple raceme) half  as  long as  the  leaves,  from  whose  
 axils  they arise.  Peduncles and pedicels  slender.  Flowers  small,  2 -4   lines across ; males largest.  Petals  rosy, three-  
 lobed ;  those  of  the  female  flowers  very  small.  Stamens many,  bright  yellow,  covered  with  microscopic  hairs ;  
 anthers  longer than  the filaments.  Ovary usually four-celled.  Berry  as large as  a pea,  eaten by  the natives,  acid.

 A very variable plant,  growing freely  as  a bush,  4 -6   feet high,  in  damp woods,  becoming  small  and  prostrate  
 in  more  alpine  and  exposed  localities,  and  more  rigid  and  straggling on  a drier  soil lower  down.  Some  of  Mr.  
 Colenso’s  specimens  of var. /3 have  the  leaves more  membranous,  sharply serrate,  and  occasionally  very irregularly  
 lobed, resembling those of a  starved plant  of A . racemosa.  The  flowers  and frait  are, however, the  same in  all  these  
 locaUties,  varjdiig  but little in  size,  and not  at  all in  s tm c tm e .S tem s   and branches woody,  covered with  red-brown  
 b a rk ;  upper  and  petioles  pubescent.  Leaves  on  short  petioles,  generally  very  coriaceous,  3  lines to  1  inch  long,  
 ovate,  obovate,  or  linear-oblong,  blunt,  crenate,  or  serrate.  Flowers  veiy  minute,  red,  solitary,  on  short  simple  
 peduncles,  almost  buried  in  sheathing  coriaceous  bracts,  rarely  two  or  three  together,  and  forming  a  raceme.  
 Berries  red,  fleshy,  1 -2   lines  across,  four-celled,  three- to  five-seeded.  SeedrS with  a bony more or  less  tuberculated  
 testa,  covered with  a fleshy  cellular coat, which  is not  separable,  and in which  the  nutrient  vessels  of  the  growing  
 seed  partly ramify.—Two  species  are  perhaps  confounded under A.fruticosa.

 Small trees,  branching freely from below,  40  feet  high, with  whitish  bark  and  brittle wood;  young branches  
 and racemes  pubescent.  Leaves  alternate,  on  short  petioles,  1 -3   inches  long,  rather  membranous,  ovate,  obovate,  
 or oblong,  blunt,  sinuate-repand  or  toothed,  rarely entire,  turning  blackish  in  diying.  Flowers  white,  fragrant,  in  
 terminal panicles,  of  which  the males  are  the  largest.  Calyx  a very minute  cup,  obscurely  five-toothed, jointed  on  
 the  top  of  the  pedicel.  Petals  valvate,  linear-oblong,  1 -2   lines lo n g ;  males  largest,  reflexed.  Stamens  alternate  
 with  the  petals;  those of  the male flowers  with  flexuose  filaments,  longer  than  the  p etals;  anthers  linear-oblong,  
 orange;  those  of  the  female  shorter,  without pollen.  Ovarium,  in  the  male flower  reduced  to  a  conical  central  
 tubercle;  in  the  female,  linear-oblong,  bluntly  tbi-ee-angled,  crowned with  three  diverging  sessile  stigmata,  one-  
 celled,  with  one pendulous  ovule  at  the top  of the  cell,  hanging  from  a short  swollen funiculus.  Berries  oval,  black,  
 shining,  fleshy, with  a  dark purple  juice,  about i  inch  long,  enclosing  a trigonous  hard nut,  with  three fiat  faces;  a  
 flat  cord runs up  one  of  the  outer  faces  of  this  nut,  and  passes  through  a  small round  hole just  below  the apex ;  
 by this  cord  the seed is  suspended.  Seed filling  the  cavity  of the n u t ;  albumen firm  and  fleshy, oily;  embryo  small,  
 axile  at  the upper  end  of the  seed.—Only  three  species  of  this  curious  genus  are  known,—the  present,  one  from  
 Norfolk  Island,  and  one  from  the  West  Coast  of  Australia;  it  is  allied  io Icacina.  (Name  in  honour  of Thomas  
 Pennant,  an eminent  Scottish naturalist.)

 A very  graceful flowering tree,  2 0-30  feet  high, which may  be  recognized  by the  characters  given  under  the  
 genus.  The wood  is  considered  the  best  for  producing fire  by friction.  The  economy of  the  ovary  and  fruit  is  
 extremely curious, as  is  often  the case with Olacineee,  and its nearly  allied  natiual orders, Santalacea and Loranthacea,  
 etc.  The fruit  of many  species  of these presents  very  anomalous  appearances,  from  such important  changes  taking  
 place in  the  youngest  state  of  the  ovarium,  as  obliteration  of  cavities  and  absorption  of  dissepiments,  and  even  of  
 unimpregnated  ovules.  This  occurs when these  organs  ai-e  still  so  rudimentary  as  only to  be recognized  by  careful  
 examination  of  the  ovary  iu  fresh  specimens,  and  from  their  very  earliest period  of  growth.  The  thi-ee  stigmata  
 aud trigonous  form  of the  ovary indicate  tlie germen  to  be  composed  of three carpellaiy leaves, and to  have  had three  
 ovules  at  some period:  these  ovules  are  in  allied  plants  suspended  from the  top  of  an  erect  column,  arising from  
 the bottom of tbe  ovary,  or  are  pendulous from  the  top  of the cell.  I  can  nowhere trace  such  a  column in  the  fleshy  
 ovary  of Pennantia,  wliich turns black when  d ry ;  but  it is  very  evident  in  the fruit,  as  the  cord passing up  the  outside  
 of  the  nut,  fig.  ],3,  and  14  (a).  The  position  of  the  two  deficient  ovules  may possibly  be recognized  in  
 the  ovary  as the  swelling of the  umbilicus,  fig.  5  and  7  (a).  The  development of a  crustaceous  nut round the  seed,  
 between it  and  the  cord,  is  not  so  readily  accounted  for,  and  1  can  only  suggest  its  being  owing to  the inner  walls  
 of the cavity  of the  ovarium  gradually becoming  thickened;  and  1  offer,  in  corroboration  of tbis  opinion, the  structure  
 of Marlea.  In  that  genus  the pendulous  ovules  are lodged iu  cavities  of the  fleshy  ovary,  which  thus  presents  
 as  many  cells  as  ovules,  the  cells  communicating  over  the  top  of  the  erect  column  from  which  the  ovules  are  
 suspended.  These  cells  harden  round  the  ripening seeds,  and  a  beiTy  (with three  nuts  or  a  three-cellcd  nut)  is  
 the result,  each  nut  perforated  at its  upper  inner  angle,  opposite  the  position  of the  apex  of the  column.  I t is  not  
 surprising  that  the  central  column  of Pennantia should,  in  its  i-ndimcntary  state,  be  included  iu  the wall  of  the  
 ovarmm.  nor that  two  cells should  be  absorbed,  nor  that two  orales  sliould  be wanting;  but  it  is  curious  (though
