He  continued  to  work  thoroughly  till  the  autumn  of 
1911,  when  an  unusually  severe  heart  attack  kept  him 
in  bed  many  weeks.  He  recovered  sufficiently  in  the 
following  spring  to  do  what  proved  to  be  his  last  field 
work,  namely,  a  study  of  the  Potentillce  growing  near  his 
house.  This  interval  was,  however,  only  a  temporary 
respite,  for  in  July  of  1912  he  was  laid  low  with  an  attack 
of  apoplexy.  This  cleared  up  sufficiently  to  enable  him 
to  converse  fairly  well,  but  left  him  unable  to  write, 
and  only  to  read  occasionally.  But,  though  practically 
confined  to  bed,  he  still  retained  his  accustomed  cheer¬ 
fulness,  and  was  as  keen  as  ever  to  hear  the  botanical 
news.  The  end  came  suddenly  on  the  28rd  of  September, 
1915,  when  he  was  only  47  years  of  age. 
Besides  the  “Flora  of  Cornwall”  a  large  amount  of 
his  work  has  been  published.  From  1891  onwards  he 
contributed  many  papers  to  the  Royal  Cornwall  Poly¬ 
technic  Society  on  botanical  subjects,  other  nature 
subjects,  and  on  Cornish  worthies.  To  the  Royal 
Cornwall  Institution  he  supplied  many  annual  botanical 
reports,  for  which,  in  1905,  he  was  awarded  its  Hen  wood 
triennial  gold  medal.  He  contributed  many  notes  and 
papers  to  the  “  Journal  of  Botany,”  including  his  chief 
paper  on  the  new  Euphrasia  he  discovered  in  1906.  He 
also  wrote  the  article  on  Botany  for  the  “Victoria  History 
of  Cornwall,”  many  notes  in  the  Reports  of  the  Watson 
Exchange  Club,  numerous  popular  articles  in  the  local 
press,  and  other  papers.  His  name  is  perpetuated  in 
Ulmus  major  Sm.,  var.  Daveyi  Henry.
