a lost art, owing to photographic processes for illustration. The Boxes of Australia 
are mostly Eucalypts. 
This species is sometimes known as " Mock Orange," because of its white, sweetly- 
scented flowers, which remind one of orange-blossom. It is sometimes called " Native 
Laurel " because of the appearance of its foliage, but the use of such names is purely 
imitative, and should not be encouraged.

Flowers. The morphology and the physiology of the flowers, and particularly 
of the stamens, have formed the subjects of investigation for many years. Following 
are the principal papers, and they are given at some length to interest our young people 
(and, indeed, others) in Nature Study. 
The reproductive organs in this species. 
J. C. Bidwill (who was Director of the Botanic Gardens, Sydney, for a short 
period in 1847) seems to have been the first botanist who drew attention to the subject. 
Writing to Captain P. P. King, R.N., F.R.S., of Sydney, on 27th September, 1847, he 
says, " I am inclined to think that your Pittosporum is only the female plant of P. 
undulatum. They are sometimes hermaphrodite, sometimes male, and sometimes 
female by abortion of the stamens ; if you examine further, I think you will find this 
to be the case." (J.H.M., in Journ. Roy. Soc. N.S.W., xlii, 90, 1908.) 
The subject appears then to have been lost sight of for a number of years. 
Following are some references.

Recently, in examining some flowers of this plant, I found the anthers very slightly developed, 
and the stigma mature, suggesting that the plant was strongly proterogynous. In flowers from another 
tree, however, the anthers were found to be well developed, while the stigma was immature. Further 
examination of similar specimens has led me to the opinion that in this species a differentiation of the 
sexes is going on. The short stamens contain pollen in an undeveloped state ; and honey is freely 
secreted. I have been unable to find any record of this fact, or any figure of the flowers with short 
stamens. Trees with flowers bearing short stamens are very plentiful here at Mt. Kembla, and Mr. E. 
Bctche, to whom I pointed out the facts, informs me that trees about Sydney also exhibit the same 
peculiarity.

Pittosporum undulatum Andr. In the majority of trees the flowers are proterandrous, the anthers 
being well developed and full of good pollen. The flowers are very attractive to insects, from their 
powerful sweet scent and free secretion of nectar. But in a small proportion of trees the anthers are small 
and short, and the pollen does not appear to be functional, in addition to which the anthers do not dehisce. 
They are very closely appressed to the base of the ovulary, and secrete nectar. The flowers of this form 
are also sweet-scented. These short anthers vary much in size, even in the same flower, and I think it
