“You will see then that two of the three species are recogniza- 
ble as marine forms, while the third, in my opinion now, is at 
least not to be referred to a known marine form. As a rule, the 
Alga: found in saline regions belong to species found in brackish 
waters on the coast. One might expect to find a large variety of 
Ulveze and Confervez in Salt Lake, and it would be of interest to 
see how closely these inland forms approximate to the littoral 
forms of the eastern and western coasts.” —A. S. Packard, Fr. 
Botanica, News —The Botanical Gazette for September prints 
an article by Prof. J. T. Rothrock on the staining and double 
staining of vegetable tissue. Grevillea for September contains 
an account, by W. L. Lindsay, of experiments on the colorific 
properties of lichens. In Trimen’s Journal of Botany for Sep- 
tember, Mr. S. LeM. Moore discusses in an interesting way the 
mimicry of seeds and fruits, and the functions of seminal append- 
ages, pointing out the resemblance of certain seeds to insects, 
spiders and shells. He concludes that “the insect-mimicing 
fruit or seed may escape from its seminivorous enemies by being 
passed over as an insect; moreover, insectivorous ones seizing it 
and finding out their mistake would be almost certain to fling it 
some distance away, by which means the species would stand a 
better chance of dispersion.”
