THE VEGETATION OF THE DISTRICTS OF

Phoenix sylvestris\ Cocos nucifera y Areca Catechu , Bambusa Tulda , 
Z?. vulgaris , Balcooa and * Z?. arundinacea . 
Perhaps the most striking facts in connection with this list are 
that, although the species as a class belong to plants that one would 
expect to be readily naturalized in our area, hardly more than 
20 per cent, readily reproduce themselves without human assistance ; 
and that in spite of what is so often said to the contrary, over 
50 per cent, of these species must have been introduced on purely 
aesthetic grounds, as there is no obvious economic quality associated 
with fully one-half of the plants in this list. About 25 per cent, 
have edible fruits or foliage, other 25 per cent, have useful timbers 
or are valuable as hedge-plants. 
Herbaceous species, natives of South-Eastern Asia that have been 
deliberately introduced, include the following:-—* Wissadula ros - 
trata , Hibiscus radiatus, * Imp a tie ns Balsamina } * Clitoria Terna - 
tea } * Bryophyllum calycinum } * Plumbago rosea and * P . zeylanica y 
* Datura fastuosa , * Torenia Fournieri } Crossandra undulaefolia } 
Justicia Betonica ) Rhinacanthus communis } * Peristrophe tinctona> 
* Ocimum sanctum , * O. gratissimum and * O. Basilicum , Coleus 
aromaticus and C. scutellarioides , * Celosia argentea and *C. cris - 
tata } * Globba sessiliflora ) * Canna indica , Crinum latifolium , 
* Typhonium Roxburghii ) * Selaginella tenera. The high propor- 
tion of species in this list that readily reproduce themselves means 
very little, because, as regards species of this kind, only those have 
been admitted into the systematic census which show a tendency to 
perpetuate themselves in our districts, or which are of economic 
interest or both. 
The number of species purposely introduced from China or Japan 
is not very great ; it includes the following, those that show a tendency 
to naturalise themselves being again distinguished by an asterisk ; in 
this case it is not necessary to distinguish herbaceous from woody 
plants :— •* Hibiscus Manihot and IT. Rosa-sinensis, * Triphasia 
Aurantiola ) Nephelium Litchi \ Rosa indica ) Eriobotrya- japomca. 
Gardenia fiori.da ) lx or a. strict a ) Diospyros Kaki ) Nemum odorum, 
* Clerodendron fragrans , Cinnajnomum Camphor a, * Sapium sebi - 
Brum, * B rous onetia papyrifera ) Ficus pumila , Thuja onentahs , ,
