Professor Jones erklärte, dass die von Herrn Goodman gegebene Beschreibung genau mit der des GleditscJiia triacanthos entsprach; Aber daß der Tränendecke-Baum lokal auf verschiedene stachelige Bäume und Sträucher, hauptsächlich Texan und Arizonian, und dasjenige der Akazie (Vachellia) weit?iesiana, das entlang der Missis-sippi wächst, zwischen Baton Rouge und New Orleans angewendet wurde; daß er nie den Namen Tränendecke gehört hatte, der auf irgendeinen Baum angewendet wurde, der in Louisiana heimisch ist. Er erklärte jedoch, dass die Acacia farnesiana nevergrew über sieben oder acht Meter hoch in

. Gaillard's medical journal. 2 SELECTIONS. Professor Jones stated that the description given by Mr. Goodmanexactly tallied with that of the GleditscJiia triacanthos ; but that thename Tear-blanket-Tree was applied locally to various pricklytrees and shrubs, chiefly Texan and Arizonian, and that one of thesewas the Acacia (Vachellia) far?iesiana, which grows along the Missis-sippi, between Baton Rouge and New Orleans; that he had neverheard the name Tear-blanket applied to any tree indigenous toLouisiana. He stated, however, that the Acacia farnesiana nevergrew over seven or eight feet high in Louisiana, possessed white spinesthat were straight and unbranched, and bore a pod that correspondedin no respect with the one described in my article. He would, however, make inquiries if I requested. This was earn-estly suggested immediately by letter. The last link in the chain of indisputable evidence was furnished bya telegram from Prof. Joseph Jones, stating that Gleditschia tria-canthos is correct beyond peradventure.. Fig. i. At the dictation of Dr. H. H. Rusby I wrote the following:Gleditschia, Genus; Natural Order, Leguminosae ; occurs in tem-perate and subtropical Asia and North America. Consists of four or SELECTIONS. 443 five species; there are two in this country, which are quite readily dis-tinguishable one from the other. Gleditschia triacanthos Linn, has a long pod with a number ofseeds in it. The pod may be straight, sickle-curved, or even twistedspirally. Gleditschia monosperma Walt, has a short pod containing but asingle seed, or very rarely two. In this section leaves are deciduous, the tree being bare in winter.It is said that along the Gulf the leaves persist during the winter. Inasmuch as it has been stated (by Dr. Seward) that the winterleaves in Louisiana contain a larger amount of the alkaloid than thesummer ones, it is possible that in this section, where the leaves neverreach the winter stage, they may be much less rich in alkaloidal proper-ties.
