The specimens you sent to me are this, larger and later than any I got. But, as you directed me to the base of the mountain for Diamorpha, you must have got this too. Your specimens have full-grown fruit. Look at them and see if the larger ones have not the regular dehiscence down the side of Sedum, and let me know. May 12, 1875. Thanks for your letter and the Sedum. Now for another find. The moment I set eyes on the Arenaria of Stone Mountain, I said, Ho! here is A. brevifolia, Nuttall, of which I had only a single stalk in herbarium. Comparing now, I was right, and Nuttall says his specimen is from Tatnall County (which is strange, that being in southeast Georgia). The question remains, Is it only a low-country form of Arenaria glabra? Your specimen--with fruit--and M. A. Curtis’s[96] from the mountains of Carolina, being in the same state, compare pretty well. I should unite them, only the seeds are different, Stone Mountain plant half the size, and shape rather different. But please rattle me out some real ripe seeds of your plant, for further comparison. At Stone Mountain I looked rather for small specimens to match with A. brevifolia. I send you a bit. I have sent the Sedum and Diamorpha yesterday to Paris, to compare and see if both are in Herbarium Michaux. I am proud of my little discovery! Ever yours, ASA GRAY. TO R. W. CHURCH. CAMBRIDGE, June 22, 1875. I must indulge, on its rising, the impulse to communicate with you, which a letter from Miss P. to my wife, just received, has awakened. If I go on as I have been going, we shall come to know nothing of each other.... She will have told you of our loss in the death of Mrs. Loring. I never knew a woman fuller of charity, humility, and good works. If there were time for a gossiping letter I or Mrs. Gray would give you some account of a trip which we made to Florida this spring. An annoying cough, and a chronic catarrh,--the consequence of a trying winter, acting upon old susceptibilities,--distressed my friends more than it did me. So, yielding to their solicitations, off we went, about the middle of March, to Washington, visiting old friends; to Augusta and Savannah, Georgia; and thence Apalachicola, a now almost deserted, but once flourishing town, on the Gulf of Mexico. We met the spring in Georgia; in Florida we were in early summer, about like our own middle June.
