ENGELMANN—NORTH AM. SPECIES OF JUNCUS. 491 
which otherwise exhibits the same structure, always marked 
with regular transverse reticulation. 
Pag. 443. J. effusus . Several forms are distributed in 
Herb. norm.; the common one from Michigan, 7, and South 
Carolina, 8, and an unusually slender one, 9, from the Cali¬ 
fornian mountains, where the common one also grows. The 
western botanists find in the saltmarshes near San Francisco 
a brown flowered variety, which may be distinguished as var. 
bruneus; inflorescence somewhat looser and fastigiate, Herb, 
n. 10, or more compact, ib.ll ; other differences, if they ex¬ 
ist, have escaped me. J 
J. patens was distributed by Dr. Kellogg in Herb. norm, 
in two forms ; 12 is a tall plant with loose panicles of green 
flowers, 13 a low (8-15 inches high) rigid form with a more 
compact darker colored inflorescence. 
Pag. 444. J. Smithii : rhizomate longe repente ; caulibus 
(lf-2-pedalibus) gracilibus teretibus farctis siccis striulatis 
basi vaginis fusco-rufis breviter aristatis instructs; paniculai 
laxse vix composite pauciflorm spatha longissima; sepalis 
sequilongis, exterioribus laneeolatis acutatis, interioribus obtu- 
sis stamina 6 fere duplo superantibus; antheris oblongis fila- 
mentum aequantibus; ovario ovato in stylum brevem attenu¬ 
ate cum stigmatibus eo sequilongis fere incluso; cetera vide

Found abundantly by Messrs. Smith, Porter and Leidy on 
Broadmountain, Pennsylvania (Herb. norm. 15) where it 
had been discovered by the former the year before ; also in 
Bausch s Gap, Lebanon county.—The very complete speci¬ 
mens sent by these gentlemen enable me to complete the 
history of this, thus far, very rare plant, which proves to be 
intermediate befween J. Balticus and J. filiformis , with the 
rootstock of the former and the inflorescence of the latter 
and with almost the seeds of J. arcticus. Seeds 0.32-0 38 line’ 
long, with short and broad appendages and a distinct rhaphe, 
distinctly but somewhat irregularly reticulate and partly also 
lineolate; epidermis easily removed after soaking 
B setaceus; a larger and a smaller form from South Caro¬ 
lina have been distributed in Herb. norm. 14 by Mr Ravenel* 
mternodes of the creeping rhizom short, stems cespitose. ’ 
Pag. 445. J. arcticus is more closely allied with J. Balti¬ 
cus and Mw than with J. Drummondii; more specimens 
obtained from the coasts of the north Pacific show that the 
var. Sitchensis is not rare there, and extends to Kamschatka: 
its characters hold their own well. 
J. Drummondii, Californian Alps, Bolander, Hb. norm. 16. 
1 ag, 446. J. Parryi ; a form with the interior sepals ob¬ 
tuse and much shorter than the exterior ones, which are as 
long as the capsule, was found by Mr. Bolander on alpine 
meadows, California.
