BOTANICAL EXCURSION TO NORTH CAROLINA. 51: 
with C. canescens, Linn. ex Boott (C. Buxbaumii, Wahl.) 
and C. conoidea, Schk., on the moist grassy brow of a preci- 
pice of the Bluff ; and towards the base of the Negro Moun- 
tain we observed C. virescens and C. digitalis, Willd. 
In a cool, sequestered brook, we found the true Carda- 
mine rotundifolia, Michx., growing like the Water-cress (for 
which it might be substituted, as its leaves have exactly the 
same taste), but producing numerous stolons two or three or 
spicis angustioribus et laxifloris erectis, superioribus brevissime peduncu- 
latis ; acheniis oblongo-ovoideis magis stipitatis. 
The figure of C. gracillima, in Professor Kunze’s Supplement to 
Schkuhr’s Carices, is excellent, except that the immature perigynia are 
represented with more distinct beaks than I have ever seen. To this 
genus, already perhaps the most extensive in the vegetable kingdom, 
after Senecio, Mr. Sullivant has recently added another species, an ac- 
count of which may be appended to this note. As Dr. Boott had already 
dedicated it to the zealous discoverer, without being aware that he had 
distributed it under another name, I trust I may be allowed to publish the 
notes of this sedulous caricographer unchanged : 
“C. Sullivantii (Boott): spica mascula solitaria cylindrica, femineis 
3-5 cylindricis erectis gracilibus pedunculatis laxifloris, superioribus con- 
tiguis, infima remota longe pedunculata basi attenuata, stigmatibus tribus, 
perigyniis ellipticis brevi-rostratis emarginatis pellucido-punctatis apice 
marginibusque piloso-hispidis squaamam ovatam ciliatam hispido-mucrona- 
tam subzquantibus. 
* Culmus bipedalis, gracilis, triqueter, pilis albis sparsis longis scabrius- 
culus, pars spicas gerens 2—9-uncialis. Folia 2 lin. lata, culmo breviora, 
marginibus nervisque scabris. Bractea infima vaginans, foliacea, culmum 
adequans, relique sensim breviores, superiores evaginatee demum seta- 
cee. Spica mascula uncialis, vix lineam lata, sessilis vel brevi-peduncu- 
lata: squame, mutice, obtuse, apice ciliolate, nervo scabro, pallide 
castanee. Spice feeminez 3-5, laxiflore, 1-14 uncias long, 1-1} lineas 
late; superiores contigue; infima remota (uno exemplo basi composita) ; 
squame pellucide ciliolate, nervo viridi scabro, hispido-mucronate. Pe- 
dunculi scabri, superiores sensim breviores. Perigynium (vix maturum) 
13 lin. longum, ¢ lin. latum, viride, enervium ? apice hispidulum, ciliatum, 
brevistipitatum, squamam subequans vel eo paululum longius. Achenium 
immaturum.” (Boott in litt.) 
Hab. in sylvaticis prope Columbum, Ohionis, ubi detexit W. S. Sulli- 
vant, cum C. pubescente, C. gracillima, ete. vigens. Affinis C. arctate (C. 
sylvatice, auct. Amer.) ex cl. Boott.— In exemplis nuperrime receptis, 
perigynia satis matura sunt ovato-elliptica, lata, compresso-plana, ener- 
via (marginibus exceptis), apice vix rostrata.
