1905, and put away in a drawer for a year and in September, 1906, 
were found to have germinated and produced a perfectly healthy 
green shoot. 
Few of the other species of the genus have set seeds, even the 
pasture land C. defixwm seems to fruit very seldom. C. northianum , 
a tidal mud species from Sarawak fruits successfully, but none of 
the other species have ever set fruit. 
The tidal mud climber, Tristellateia australasica, is cultivated in 
all gardens, and flowers and fruits easily. Though never seen wild 
except in salt mud, it is a much more free flowerer in the dry clay 
soil of the gardens. It grows readily from seed but has never 
spread. 
* Casuarina equiseti folia is a sea-shore tree which has the peculiar 
habit of growing in a single line on sandy beaches just above the 
loose sand where the ground is firmer. It is not uncommon to see 
a line of these trees some distance from the sea where the sea has 
receded, the line of trees marking out the former edge of the sea 
beach. Planted inland in swampy ground it grows to a fair size, 
but usually never flowers. In drier soil it often flowers and fruits 
profusely but does not spread of itself. 
C. snmatrana which inhabits rocky and sandy spots close to the 
sea and tidal river in Borneo grows well in the stiff clay of the 
Botanic Gardens, fruiting regularly, but quite old trees have still 
retained the cone-shaped form of the young plant, and show no 
signs of taking on the characteristic adult form resembling a Scotch 
Fir with a tall straight stem and small rounded crown. 
Flagellaria indica is a sea-shore plant, which grows very strongly 
and rapidly in the gardens especially however in damp spots by 
the lake. It flowers and fruits abundantly and has spread itself 
to some distance across the gardens. 
Acrostichu?n aureum , typically a tidal mud fern, when isolated 
by the silting up of the tidal river by which it grows, remains for 
a long time, but does not apparently spread. A large clump grows 
in the Economic Gardens, on ground formerly a tidal river bed, 
as Nipa fruits have been found in it, but there is nothing to show' 
that there has been a tidal river here since the founding of 
Singapore. It shows no sign of spreading. 
I have also seen Pluchea indica , a tidal mud plant far inland and 
faraway from any river in Tanglin, but it has not spread and I 
have failed to cultivate it at Tanglin. 
These tidal mud plants often persist long ■ after the locality has 
ceased to be near a river or the sea, but they fail to propagate 
themselves. 
Most of our mountain .plants fail to accommodate themselves to 
the low country and perish soon after being brought down, 
curiously the Conifers , Dammar a, Dacrydium and Podocarpus 
Cupressinus , although never seen below 2,000 feet elevation do 
very well in the Botanic Gardens. The first has flowered more
