Many American botanists believe that this is the same as one collected by Jeffrey, in California, and named by Mr. Murray P. Balfouriana, and if so, the name of P. aristata will have to be dropped, in accordance with the recognized botanical law of priority. It must be confessed, however, that no trees of P. aristata have been found that have the cones quite so much narrowed out as those figured from Jeffrey's collection as P. Balfouriana. Neither, so far as we know, have any more of this form been collected since Jeffrey's time, though California has been pretty well explored. We would thank any of our readers who may live in those districts, and may find very narrow-coned forms of Pinus aristata, to send us specimens. Mr. Jeffrey's cones came from near Mount Shasta, in Northern California.
