amongst Eastern peoples, known .as ‘‘jujubes,’’ so the .— 
tree is sometimes called a ‘“‘Jujube Tree,” though that — 
name rightly belongs to a closely related species also found 
in Palestine, though not hereabouts. 
Note—Mr. A. A. Hamilton contributes the following 
note on the above plants :— 
“The Tamarisks are species of Zamarix, and that 
i: mentioned by Mr. Carne as timber is 7’. gallica var arborea, 
a common shrub in Sydney gardens. The Sycamore Fig i is 
Ficus sycamorus. The Christ Thorn is Zizyphus spina- 
Christi, and the jujube tree is Z. jujuba. It may be 
added one of the plants credited with the production of 
manna is ZJ'amarix manntfera,

NOTES AND COMMENTS. 
ANTS AND FLOWERS.—In seconding a vote of thanks 
to Mr. Hamilton at the meeting on 5th November, Mr. 
- Froggatt described an extremely interesting relationship 
which had come under his notice. When the “‘Bumble 
Tree’? or “‘Wild Pomegranite’’ (Capparis mitchellt) is 
in blossom, it is, during the day, frequented by large num- 
bers of the common mound ant (Iridomyrmex detectus), 
which prevent. access to the flowers by the native bee 
(Anthophora preisst), with the result that the latter has 
aequired the habit of working at night when the ants are 
absent.
