ACACIA SEEDLINGS. 151 



Many of these glands, especially those which occur on 

 leaves of seedlings of the Uninerves section, secrete a 

 honey-like substance, chiefly during the spring and summer 

 months, on which insects, especially ants, evidently feed; 

 two species which commonly visit them have been kindly 

 identified by Mr. W. W. Froggatt as Iridomyrmex rufo- 

 niger and Ectatomma metallicum. 



In addition to the honey-like matter, the glands on young 

 phyllodes of advanced seedlings of A. Westoni, A. penni- 

 nervis, and to a slight extent of A. pycnantha, often exude 

 a white substance which looks to be somewhat of the tex- 

 ture of cream, and although these white spots are scarcely 

 1 mm. in diameter, they may be seen distinctly on the first 

 two species from distances up to five yards from the plant. 



Flowering Seedlings. 

 In Part V, (p. 146), several examples were quoted of 

 Acacia seedlings having flowered while growing in pots, 

 and the following, which are growing in 4, 5 or 6-inch pots, 

 are now added to the list : — A. amblygona, A. asparagoides 

 (one dwarf plant eleven months old and four inches high 

 bore two flowers), A. continua (fairly freely at 21 months 

 old), A. Howittii, A. juniperina (sparsely at 17 months), 

 A. lineata, A. obtusata and A, verticillata. A plant of 

 A. venulosa four years old, and grown in a four inch pot, 

 flowered for the second time. 



Fertile Seeds from Pot Plants. 

 Many seeds ripened on a young plant of Acacia crassi- 

 uscula, grown in a six-inch pot, and, of thirteen planted, 

 twelve germinated readily.
