ROOT-SHOOTS IN CASUAR1NA GLAVGA. 
The are a considerable number of species of the genus Casuarina, 
chiefly natives of Australia, of which many have been introduce 
into the Botanic Gardens, but except in the cases of the indigenous 
Ru tree, Casuarina equisetifolia and C. sumatrana of the Malay 7* 1an< j 
none have as yet adapted themselves to our flora wi 
exception of Casuarina glauca Sieb, a native of Queensland ^hichwas 
introduced here a few years ago and has grown vigorous & 
a valuable addition to our ornamental and curious trees. Ris P 
has been planted out on the grass plots and as it roofs i 0 » 1 
have here and there got cut or wounded by the grass cutters, 
these cases the Casuarina has thrown up shoots from e '7 ° ' , 
root, from which it will be probably easy to propagate it. ih 
emission of shoots from roofs of trees is by no means uncommon 1 
in this country. The Spathodea is commonly so propagated in this 
country and most, at least of the trees of this plant in Singapore, at 
least have been so obtained, as it seldom fruits here ( ave in 
only seen it fruiting in Kuala Lumpur). Albizzia Moluccana is 
another plant which produces strong plants from the roots, an 
Tembusu, Fagraea fragrans, also produces shoots on wounded 
roots, but these never seem to develop into trees. The mos curio 
instance which I have met with was in the case o a rat cm 
(G. globulosa Ridl) which threw up from its root a stem about a toot 
tall which bore not only leaves but flowers. 
I have, however, never seen a case of the production of shoots 
from roots in any of the Casuarinas and our^pecies here are at least 
very difficult to reproduce from cuttings. It is usual to find thatthe 
trees which throw up shoots from the roots are those with soft w°°d 
and plenty of suppressed buds so that they are easily reproduced 
from cuttings. The Casuarinas, however, have hard wood, are 
difficult or almost impossible to reproduce from cuttings, and indeed 
suffer badly and often die if pruned at all, so that it was 'tot to be 
expected that they would produce root-shoots, and Hhink this action 
in Casuarina glauca to be worth recording. Ed.
