Carex Nuttallii, 3ch\v., for C. crus-corvi, ShLittle\vorth._ This 
name was first published in 1824, by Schweinitz, in his preliminary- 
Analytical Table, a list containing no descriptions, and intended as a 
temporary affair to precede his monograph. The plant was credited 
to Arkansas. It had spikes " corymbosely ramose," with a habit 
"near C Indicar The name may have referred to theplant now 
called crus-corvi, but it is entirely uncertain, and Schweinitz did not 
again use it. 
C albo-lutescens, Schw., for C. aditshi, Boott. This name was 
also published in the Analytical Table, and was probably founded 
upon an immature specimen. So uncertain was the species that in 
the subsequent monograph of Schweinitz and Torrey the name was not 
mentioned. Dr. Boott, III, iii., 120, makes it a synonym for C. 
stramitiea, var. festucacea. 
C. Muskin^umensis, Schw., for C. arida, Schw. and Torr. Under 
rigid rules of priority this name will hold. It was made by 
Schweinitz in his Table, but, disliking it, he and Torrey substituted 
arida in their Monograph, under which name it was first described. 
Rules of nomenclature in those days of comparatively few narnes 
were less rigid than now, and no breach was made in suppressing 
a little-known and unwieldy name. It is no service to science to 
unearth a pame buried by common consent in its infancy, when its 
unearthing but increases confusion. 
C. niicrodonta, Torr., for C. Crawei, Dew.— This name was made 
by Torrey and Hooker and published in Torrey's Monograph of the 
Cyperacese in 1836. It was given to a Texas plant. No. 439 of 
Drummond's collection, It refers to a plant differing from Carex 
Crawei in its toothed perigynlum and laxer habit. It may prove to 
be an older name for C. alveata, Boott. Texas specimens referred to 
C. niicrodonta in the Gray Herbarium approach C. gratiularis in ap- 
pearance. When sufficient material accumulates, C. Crataei :ind C. 
microdonta may be found to be the extremes of the same species, but 
at present they must be kept distinct.

Concerning Abutilon.-On further consideration, I am convinced 
that Professor Macloskie and myself are wrong in our morphology 
—a little confused as to facts. In Abutiloti Avicenncs there sometimes 
occurs a bract like that which I noticed in another species, and also one 
or two smaller ones; but they are below the joint in the peduncle or 
pedicel, and I think that the small bracts are axillary to the larger 
one. However that may be, it seems plain that this is an attempt 
toward the two-flowered peduncle, which is quite common in that 
species. Now the " involucel," as botanists are particular to call it, 
of mallow and hibiscus is always close to the calyx, above the 
articulation when there is any, and never has a sign of any second 
flower within it. It is so strictly connected with the fiower that some 
botanists have called it epicalyx. Hypocalyx would be a better term 
^ a special name were needed. I have not yet found any bract on 
the peduncle of A. vcxiliarium, but I do find what appears to be a 
five-lobed involucel, close pressed to the base of the calyx and wholly
