WE desire to invite attention to three interesting plants 
described by us some years ago’ as Suggestive of hybridism, 
and we offer some notes upon them. The direct evidence 
of hybridism in Eucalyptus is usually a matter of inference 
and not of direct experiment; it seems to us that in two 
oi the plants referred to, it is desirable to attach names 
to them. 
A. (op. cit., p. 199). We have no further evidence to 
ofier in this case, and consider that it is one for further 
investigation. We have since found a few additional trees 
belonging to this form, but they were only about a quarter 
of a mile from the original tree. 
B. (op. cit., p. 200). Many small mallee-like forms are 
very puzzling, partly because they are so small that cer- 
tain characters are not obvious as in the case of large trees, 
and partly because the Renanthere, to which class this 
particular plant belongs, present many points of resem- 
blance. 
As regards B. it appears to be identical with EH. he- 
mastoma, Sm. var. montana, Deane and Maiden,’ from 
Mount Victoria about four miles from Blackheath. 
Since then, one of us has suggested* the close resemblance 
of the Mount Victorian specimens to EH. amygdalina, Labill. 
var. nitida, Benth. (HE. nitida, Hook. f.) of Tasmania.
