The material for tests {a) and {b) was collected at Sunny- 

 "bank in May and November, 1919, respectively. As some 

 doubt existed as to whether the positive reaction with the 

 pistil was due to the pollen adhering to it, a further test 

 c) was carried out with the stigmatic surface cleaned of 

 pollen with the above results. This last material was 

 collected in the Glass House Mountains district in February, 

 1920. 



The anthers of Lomatia flowers are strongly cyan- 

 ogenetic. There is stiU some doubt in regard to the stigma 

 owing to the difficulty of completely freeing the stigmatic 

 surface of poUen grains, many of which are in a state of 

 germination. The possibility of Lomatia flowers proving 

 dangerous to bees owing to the cyanophoric properties of 

 the pollen seems to us worthy of consideration by entom- 

 ologists and apiarists. 



Lomatia silaifolia R.Br. var. induta F. v. M. 

 This variety jdelded in all its parts reactions identical 

 with those recorded for the normal form. 



Both fohage and flowers of the following species have 

 been tested with negative results : — 



Conospermum taxifolium, Sm. ; Strangea linearis 

 Meissn. ; Grevillea Hilliana F.v.M. ; Grevillea pinna- 

 tifida Bail ; Stenocarpus sinuatus Endl. ; Banksia integ- 

 rifolia Linn. f. ; Buckinghamia celsisnma F.v.M.
