444 - TRANS. OF THE ACAD. OF SCIENCE. 
American specimens are in nowise different from the Euro- 
pean ones; the seeds are obovate, strongly apiculate, with a 
very distinct raphe, and are irregularly and rather indistinetly 
reticulated. 
10. J. Smiran, n. sp.: rhizomate? vaginis? foliis? caulibus 
bipedalibus teretibus farctis siccis striulatis; panicule laxze 
subsimplicis pauciflore spatha longissima ; sepalis zequilongis, 
exterioribus acutatis, interioribus obtusis ; staminibus 6; cap- 
sulz exsertz subglobose acute mucronate (fuscate) trilocu-

obovato-oblongis obtusis vix apiculatis irregulariter reticu-

Pennsylvania, in a sphagnous swamp on Broad Mountain 
near Pottsvillle, Schuylkill county, where Mr. Charles £E. 
Smith, of Philadelphia, for whom this species is named (J. 
Smithii, Kunth, is the English J. tenwis), discovered it in 
June, 1865, with nearly ripe fruit, and where he expects to 
obtain more complete specimens in the coming season, as it 
grows in a very accessible, but, thus far, little explored part of 
Pennsylvania. We will then learn whether I am correct in 
my surmise that it is a leaf-bearing species, closely allied to 
J. setaceus. The question may even arise, whether our plant 
is not the true J. setacews of Rostkovius, as he eredits it to 
Pennsylvania, and, so far as I know, the plant we take to be 
setaceus has not lately been found so far north. The figure 
of Rostkovius is too poor to decide the question, but his 
description is full enough to point to our setaceus; the “three- 
leaved calyx”—t. e., the three bracts under the flower by 
which he distinguishes his species from J. filiformis—are 
found in most flowers of both J. Smithii and J. setacews, and 
also in some other species, e. g., J. tenuis, but not in J. filt- 
Sormis; the lowest of those three bracts generally bears an 
abortive bud in its axil, and has, therefore, another morpho- 
logical value than the two upper ones.—The thin and wiry 
stems before me are two feet high, eight or nine inches of 
which belong to the spathe; the flowers are scarcely more 
than one line long, not much more than half as long as those 
of J. setaceus; the anthers had fallen off and only the six 
filaments remained ; the thick but sharply angled and pointed 
eapsule is light brown and shining; its valves seem to tear 
away from the dissepiments when it opens. The seeds are 
few and of large size, 0.4 line long, and irregularly ribbed 
and reticulated.—The small flower, the form of the sepals, 
the exsert, angular capsule, and the more elongated and 
differently marked seeds distinguish it abundantly from the 
next. 
11. J. seraceus, Rostk. Mon. June. 15, t.1, f. 2, is a reg- 
ularly leaf-bearing species, though neither its author nor
