What induces me to refer to your paragraph is to ask whether your “following the glacial period,” that is, recent introduction, means in your thought that our species is a direct descendant of Corema alba, which by some chance got wafted across the Atlantic. That is the most probable notion, next to my theory. For consider, we know the genus only on these two opposite shores. Perhaps--so far as I know, there is no more C. alba in the Old World than C. Conradii in the New. And if it were in New England that the former occurs, we could say that the Old World received the genus from the New--via the Gulf Stream. November 6. ... I start farther back than the retreat of the glaciers. I suppose that the common ancestor of both Coremas was in the high north before the glacial period, and that the two, in their limited but dissociated habitats, are what is left after such vicissitudes! In that view it does not matter how long New England coast was under water. Our plant and its companions were then further south or west. Yours ever, A. GRAY. On the approach of Dr. Gray’s seventy-fifth birthday it was suggested among the younger botanists that some tribute of love and respect should be presented to him. Accordingly a letter was sent to all botanists whose addresses could be obtained within the very limited time. A silver vase was decided upon, and designs furnished, which were most happily and beautifully carried out. The description, copied from the “Botanical Gazette,” gives its size and decorations. “It is about eleven inches high exclusive of the ebony pedestal, which is surrounded by a hoop of hammered silver, bearing the inscription ‘1810, November eighteenth, 1885--Asa Gray--in token of the universal esteem of American Botanists.’ “The decoration of one side is Graya polygaloides, surrounded by Aquilegia Canadensis, Centaurea Americana, Jeffersonia diphylla, Rudbeckia speciosa, and Mitchella repens. On the other Shortia galacifolia, Lilium Grayi, Aster Bigelovii, Solidago serotina, and Epigæa repens. The lower part of the handles runs into a cluster of Dionæa leaves, which clasps the body of the vase, and their upper parts are covered with Notholæna Grayi. Adlumia cirrhosa trails over the whole background. The entire surface is oxidized, which gives greater relief to the decorations.” Greetings in the form of cards and letters, sent by those who gave the vase, were placed on a silver salver accompanying the gift, with the inscription, “Bearing the greetings of one hundred and eighty botanists of North America to Asa Gray on his seventy-fifth birthday, November 18th, 1885.” Dr. Gray was exceedingly touched and delighted, as well as overwhelmed with surprise. And the day, with pleasant calls and congratulations from friends and neighbors, gifts of flowers with warm and kindly notes, was made a memorable one indeed. His response to the senders of the vase was printed and sent to all who could be reached.
