This species, which was included in the earlier editions of 

 Gray's Manual, but omitted in the 6th edition, is represented in 

 the Kew Herbarium by abundant specimens collected by Drum- 

 mond years ago at Philadelphia, and in the Torrey Herbarium 

 by specimens from Baltimore. It does not appear to have been 

 recently found in the United States. 



RJius typJiina, L. Amoen. Acad. iv. 311 (1760). 

 Datisca hirta, L. Sp. PI. 1037 (1753). 



The type of Datisca Jiirta preserved in the Linnsean Herba- 

 rium is a specimen of the Stag-horn Sumach in the condition of 

 the inflorescence reverting to leaves, a phenomenon which fre- 

 quently occurs in this and related species. Linnaeus had the 

 plant from Kalm, and it was collected at Philadelphia. Although 

 hirta is thus the oldest specific name associated with the plant, 

 we are, I think, debarred from using it by the publication of 

 RJuis hirta, Harv., as a synonym by Engler in DC. Monog. 

 Phan. iv. 425 (1883), where this is referred to R. tridcntata, 

 Sond.

 Wisteria, Nutt. Gen. ii. 115 (18 18). 

 RafineSque cites Glycine frutescens, L., as an equivalent for 

 his proposed genus KraiinJiia, so there is no question of the plant 

 intended. 



Cruminium, Desv. Ann. Sci. Nat. (I) ix. 423 (1826). 

 Centroseuia, Benth. Ann. Mus. Wien. ii. 117 (1840). 

 Clitoria § Centroseuia, DC. Prodr. ii. 234 (1825). 

 The genus is founded on the plant commonly known as Cen- 

 troseuia Pluuiieri, Benth. {Ci uuiininui giganteuui, Desv.). 

 The North American species is Cruminium Virginianum (L). 

 Clitoria Virginiana, L. Sp. PI. 753 (1753). Centroseuia Vir- 

 giniana, Benth. Ann. Mus. Wein. ii. 120 (1840). 



Gleditsehia aqnatica^ Marsh Arb. Amer. 54 (1785). 

 This, I believe, is the oldest available name for the Water 

 Locust of the Southern States. To be sure, as pointed out by
