mention the plant either as a species or variety. The material now 
available shows that 2. leptophyllum was well grounded and is read- 
ily distinguishable from the related species. Among these, it most 
nearly approaches /. capillifolium (Lam.) Small (£. jfoeniculaceum 
Willd.), and has similar very fine filiform-linear entire, pinnate, or dis- 
sected leaves, but it differs in the long simple recurved-spreading 
secund-racemose branches of its inflorescence, the heads of E. capilli- 
Jolium being borne in compound somewhat fastigiate leafy panicles. 
In E. capillifolium, furthermore, the involucral scales are green and 
oblong, rather abruptly pointed and but slightly scarious at the mar- 
gins, while in £. leptophyllum 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. leptophyllum have 
been examined :— Georgia: near Savannah, Herbemont (hb. DC.). 
Sour Caroxina: damp pine land, Santee Canal, September, Ravenel 
(hb. Gray). Fxorrpa: without locality, Leavenworth ; Braidentown, 
Tracy, n. 7099 (hb. Gray), distributed as E. capillifolium. 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 2. leptophyl-

Eupatorium loxense Klatt, Aun. k. k. Naturh. Hofmus. Wien, ix. 357 
(1894). This species, founded ona plant collected by Jameson at Loxa, 
Ecuador, has been examined both as to its type 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. BerBERIroLiA HBK. Nov. Gen. et Spec. iv. 57 
(1820), may well belong to that species. -
