Saturday, went to dine at Mr. Webb’s; a little party,--a bachelors’ party, for Webb is single,--consisting of Dr. Montagne, M. Berthelot, M. and Mme. Ramon de la Sagra, M. Spach and his wife, and a young Spaniard whose name I do not recollect. Webb is quite a polyglot; he speaks French, Spanish, Portuguese, Italian, Modern Greek, and I know not what besides his mother tongue. At half past nine I left, took a cabriolet for Delessert’s, where I had been invited to an evening party; found there several botanists and persons I knew. Delessert received me cordially, introduced me to Madame D., who I was rejoiced to find spoke English very well. The suite of rooms thrown open was very splendid, and communicating with the last was a pretty greenhouse, filled with vigorous plants, all in fine bloom; the whole, carpeted and lighted, presented a most inviting appearance. The brothers Delessert are said to be very rich, and I suppose can well afford such an expensive establishment. The party broke up at eleven. Besides tea, which is quite English, though the French are getting more into the custom of using it we had ices, etc., but nothing else. The whole affair was conducted without any parade and in quiet good taste.... Notabilia varia.--Ellimia, Nutt., was described a little before us by two authors under two different names: First by Cambessides in Jacquemont’s Travels, under the name of Oligomeris; second by Webb and Berthollet, “Histoire Naturelle des Iles Canaries,” under the name of Resedella; Webb has Jacquemont’s plant from the Himalaya and his own growing together; they are absolutely the same. I am to examine them soon, but have scarce a doubt they are even the same species as ours. Webb has promised me a specimen. It is also the Reseda glauca of Delile ex Egypto. It is curious that the plant should at the same time be described from almost every part of the world, and not less so that the three names hit upon should have all meant the same thing, namely, a reduced reseda. I have just spent the evening with Gay. He is publishing Carices in “Annales des Sciences Naturelles:” has hit upon some of Boott’s notions; but not all. He is a laboriously minute observer, and will do pretty well, but like Boott inclines to make too many species. He insists upon describing the small form of C. Hitchcockiana from Dr. Sartwell and Kentucky as a distinct species, in which he may be right. He wished to name it after me, but I declined the honor, and have transferred it to Dr. Sartwell, the discoverer, whose name it is to bear....
