A\  coccinea^  Lour.  Native  of  Cochin  China  and  China. 
R.  imschootiana,  Rolfe.  Native  of  Assaiu. 
The  only  others  are  R.  biliiiouis,  Rchb.  f.  of  Horneo,  R.  sulingi, 
of  Java  and  R.  tr ichoglottis,  Ridl.  of  ]>orneo. 
. The  plant  coiiimonly  called  Reiianthcni  Lowii,  does  not  really 
belong  to  this  genus. 
R.  a7'achiiitcs^  Lind,  is  the  largest  and  strongest  grower  and  a 
very  regular  flowerer.  The  flower  sprays  are  large  and  the  flowers 
3 inches  across,  the  largest  in  the  genus,  the  sepals  and  petals  are 
green  with  blotches  of  brown,  the  lip  white. 
F'rom  its  curved  lateral  sepals  and  straight  upper  one,  it  has  ob- 
tained the  name  of  scorpion  orchid,  as  it  vaguely  re-calls  the  ap- 
pearance of  that  creature.  It  has  a strong  scent  of  musk  emitted 
from  the  tip  of  the  upper  sepal,  whic  h is  curved  back.  It  flowers 
twice  or  oftener  a year,  January  and  July,  and  occasionally  fruits. 
R.  Maingayi,  Hook.  iil.  is  nearly  as  big  a plant,  but  the  leaves 
are  more  flaccid.  The  panicles  are  usually  large  and  loose  and  the 
flowers  distant,  quite  scentless  of  a similar  shape  to  those  of  the 
previous  species,  and  nearly  as  large,  the  ground  colour  white  or 
pinkish  white,  with  numerous  blotches  of  shrimp-pink.  In  some 
forms  the  flowers  are  almost  suffused  entirely  with  dark  pink.  It 
is  a very  beautiful  species,  but  a much  shyer  flowerer.  Very  line 
sprays  however  are  often  to  be  seen  in  Singapore  Gardens. 
R.  alba,  Ridl.  was  fl'^st  met  with  by  myself  climbing  over 
bushes  in  hot  open  sandy  country  in  Pahang.  It  occurs  in  many 
places  in  the  Peninsula  especially  near  the  sea  I have  seen  it  in 
immense  abundance  climbing  over  low  trees  in  an  island  near 
Singapore,  and  emitting  so  many  of  its  long  roots  that  they  formed 
a curtain  that  had  to  be  cut  through  before  one  could  get  through 
the  bushes.  It  is  rather  shorter  in  the  stem  than  the  preceding 
species,  and  somewliat  brittle,  ddie  leaves  are  more  fleshy  and 
rigid  and  often  minutely  toothed  at  the  base,  especially  in  plants 
grown  in  full  sun.  The  flowers  are  smaller  than  those  of  R.  7nain- 
gayl,  in  a loose  panicle,  or  a spike  in  small  plants.  They  are  white. 
R.  matiituia,  Lindl.  is  a plant  of  much  lower  habit  one  or  two 
feet  tall  with  speckled  stems  and  narrow  ligulate  leaves,  rather  stiff. 
The  sprays  about  8 or  9 inches  long,  the  flowers  about  20  scattered 
rather  narrow,  red  or  orange  spotted  with  darker  colour,  the  lip 
white  with  a central  red  spot.  It  grows  usually  on  rocks,  and  does 
not  seem  to  be  a very  easy  plant  to  cultivate.  It  appears  to  be 
rare  in  the  Peninsula,  but  has  been  found  by  Wray,  in  Perak,  and 
by  myself  also  on  rocks  in  forest  on  Bujong  Malacca.  It  seems  to 
be  commoner  in  Borneo. 
R.  micranthn y Lindl.  is  often  to  be  found  on  rocks  overhang- 
ing the  sea,  all  over  the  Peninsula.  The  stems  are  tolerably  stout 
about  10  or  i2  feet  long,  the  leaves  short  and  !; road  usually  blotched 
with  red  tlu!  flower  sprays  are  about  a fool  or  more  long,  with  hori- 
zontal l^rancluas  densely  covered  ^\•ith  vcr\-  small  deej)  red  flowers
