mention the plant either as a species or variety. The material now 

 available shows that E. leptophyllum was well grounded and is read- 

 ily distinguishable from the related species. Among these, it most 

 nearly approaches E. capilUfoUum (Lam.) Small {E. foeniculaceum 

 Willd.), and has similar very fine filiform-linear entire, pinnate, or dis- 

 sected leaves, but it difters in the long simple recurved-spreading 

 secund -racemose branches of its inflorescence, the heads of E. capilU- 

 foUum being borne in compound somewhat fastigiate leafy panicles. 

 In E. capilUfoUuni, furthermore, the involucral scales are green and 

 oblong, rather abruptly pointed and but slightly scarious at the mar- 

 gins, while in E. leptophjUum they are inclined to be brown (in dried 

 specimens) and have strongly contrasting white margins. In form they 

 are linear-oblong or lance-linear and tend to be attenuate, often ending 

 in a very sharp point. The simple recurved racemose branches of the 

 inflorescence are 4-10 cm. long, and as DeCandolle remarks in the 

 original description, the inflorescence suggests strongly that of some of 

 the golden-rods. The following specimens of E. leptophyUum have 

 been examined : — Georgia : near Savannah, Herhemont (hb. DC). 

 South Carolina : damp pine land, San tee Canal, September, Ravenel 

 (hb. Gray). Florida : without locality, Leavenworth ; Braidentown, 

 Tract/, n. 7099 (hb. Gray), distributed as E. capUUfoUum. The species 

 shows some variation in its leaves. They are described as entire by 

 DeCandolle, and this is true in the upper parts of the specimens at 

 hand, but the lowermost leaves when shown are pinnately divided into 

 filiform or narrowly linear segments. In a second specimen collected 

 on the Santee Canal by Ravenel (October), the leaves are not only more 

 dissected than in the others, but the segments, although still very nar- 

 row, are distinctly flat rather than filiform. The close correspondence 

 of all these specimens, however, in the more essential characters of in- 

 florescence, involucres, flowers, achenes, and pappus, confirm the belief 

 that they are only individual or formal leaf- variations of E. leptophjl- 

 lum DC. 



Eupatorium loxeme Klatt, Ann. k. k. Naturh. Hofmus. Wien, ix. 357 

 (1894). This species, founded on a plant collected by Jameson at Loxa, 

 Ecuador, has been examined both as to its tj^e preserved in the her- 

 barium of the Imperial Natural History Museum at Vienna and the 

 specimen in the herbarium of the late Dr. Klatt. It is clearly the 

 staminate plant of a Baccharis, and so far as may be judged from 

 the characters of B. berberifolia HBK. Nov. Gen. et Spec. iv. 57 

 (1820), may well belong to that species.
