one way more than another. The cauline leaves all 
tend to become vertical (as in several other Compo- 
site), but present neither face nor edge north. 
But three years ago Lapham of Wisconsin wrote 
me that, though the plant near Milwaukee showed no 
“ polarity ” (and so he never believed in it), yet on 
going farther west, on the prairies, he found it did 
generally turn all to the north there. 
If I remember aright, though, he said the surfaces 
of the leaf look north and south. You say the edges? 
How is this? Compare notes with Lapham. . . . 
What do you think I am about now? Revising gen- 
era of Myrtaceze for Exploring Expedition collection. 
In these exotic orders I frequently find the genera 
so at loose ends that I cannot make the plants of our 
collection lie comfortably till I have given the genera 
a good shaking up. I should be tempted to do much 
more of this if I could work at Hooker’s, or in Paris. 
It is quite as well not, as it would cost no end of 
time. . . 
I have fodca some Fouquiera seedlings up in the 
Garden. I am right about it; not Thier The leaf 
is not axillary and its petiole inclosed in the spine ; 
but the spine is a hardened inferior portion of the 
petiole that a and from which the rest falls 
away clean. . .
