NORTH AMERICAN SPECIES OF JUNCUS. 247 
mucronatis ; antheris sex late linearibus filamento ter quaterve longioribus demum deciduis ; stylo ovario ovato multo 
reviore ; capsula ovata obtusa mucronulata sepala exteriora equante placentis tumidis triloculari; seminibus late 
obovatis obtusis vix apiculatis tenuissime (sub lente) costato lineolatis (J. maritimus, auct. Amer.). 
Atlantic coast of the United States from New Jersey to Florida and Texas. io Glonly allied to the European 
J. maritimus, for which it has eae been taken, until Scheele, without discovering its distinctive seesaw gave it 
anew name. It is well marked by an open epieadinig panicle ste slender flexible branches; deciduous anthers; a very 
short style, which is not half as long as the obtuse ovary ; an obtuse, short, deep brown capsule ; remarkably large, 
spongy placente, which fill the greater space of the capsular a and the like of which I have not seen in any other 
species ; and obtuse, tailless seeds, marked with very slight wavy ribs and slighter cross lines. — J. maritimus bears a 
rigid, fastigiate panicle, persistent anthers, an ovary attenuated into a style of nearly its own length, a greenish, ne 
capsule which usually exceeds the sepals, placente of ordinary size, and seeds with distinct tails and stronger 
The light brownish flowers are 1.5 lines, and the seeds 0.3 line long, and nearly 0.2 line thick. 
This is the only Juncus in which occasionally unisexual specimens occur (Georgia, Le Conte, in Hb. Acad, 
Philad., and Florida, Chapman, in Hb. A. Gray); these plants, pistillate by abortion of ea stamens, have a stricter 
but fewer flowered panicle, and thus present a very unusual aspect ; our southern botanists ought to find out under 
which conditions this form occurs, and whether any corresponding staminate plants grow with them. 
3. J. compressus, H. B. K. nov. gen. 1, 235; Kunth, Enum. 3, 317: rhizomate repente, gaa: saree [440] 
maribus sesquipedalibus) compressis farctis siccis tenuiter striatis ; vaginis aphyllis muticis seu 
rune simillima breviora gerentibus; spatha paniculam compositam seu decompositam ad ultimos ramos ipeeer era 
gequante seu superante ; sepalis eae a neers acutis seu subulato-a acutatis, interioribus paulo brevioribus 
Seedsals stamina sex dimida seu tertia parte superantibus ; antheris late linearibus filamento brevi multo (quad- 
ruplo quintuplo) longioribus ; stigmatibus ovarium cum stylo 0 fere equilongo subequantibus; capsula ovata acuta 
(inclusa ?) conte ; seminibus ovatis obtusis vix barge leviusculis, 
alin sscicge in sandy river bottoms, May 1, in flower; Calif. State Survey No. 529, the only locality in our 
flora ee to me. Dr. J. Gregg collected the same species in northern Mexico ; smaller forms, eight inches high, 
with very short ie and a stouter one, 12-18 inches high, with longer spathe and larger panicle. The Califor- 
nian specimens are 10-15 inches high, with a spathe 2-4 inches long; panicle small, rather simple, only the extreme 
branchlets with one-sided flowers ; the reddish streaks on the sepals very pale; the only capsule seen (not ripe) was 
shorter than the sepals and aE a few large seeds, 0.37 line long and apparently nd slightly lineolate. — This 
plant is evidently closely allied to J. Balticus ; it bears very similar but paler flowers, with the same stout anthers on 
very short filaments ; but the flattened stem and the frequent occurrence of leaves tale it. Among Fendler’s 
Sante Fé plants, however, I find under No. 860, with the legitimate J. Ba/ticus, var. montanus, small specimens 6-7 
inches high, with the darker flowers of the former, but with a slightly compressed stem, and occasionally with a leaf 
from the vagine. Is that a form intermediate between and connecting both species 
. BREWERI, n. sp. : rhizomate perpendiculari; caulibus exspitosis (pedalibus) compressis levibus farctis ; 
vaginis nervosis muticis ; spatha paniculam paucifloram in ultimis ramis secundam longe superante ; sepalis subequali- 
bus ovatis late marginatis abrupte acuminatis ; antheris late linearibus filamento brevi multo (quadruplo quintuplo) 
longioribus ; stigmatibus ovarium cum stylo equilongo equantibus exsertis ; capsula . ... 
sandy soil, near Monterey, California, the same unfortunate locality that has so often heen confounded by 
botanical writers with Monterey in Nuevo Leon, Real del Monte in Mexico, and even Montreal in Canada; Calif. 
State Survey No. 651, in flower in the latter part of May. — The perpendicular rhizoma (if a constant character) 
and the strongly compressed stem, together with the broad and abruptly acuminate sepals, distinguish it from [441] 
the smaller forms of J. Balticus, the absence of leaves and the form of the sepals from J. compressus, with both 
of which it is closely allied by the form of the stamens, so different from those of any other American or European 
Juncus of this section. — Stems a foot high, four or five inches of which belong to the spathe ; inflorescence small, 
rather compact ; flowers 2} lines long ; sepals dark brown, greenish in the middle, membranaceous on margin. — I 
have named this plant for Prof. Wm. H. Brewer, in acknowledgment of his services in the cause of science in 
California. 
5. J. Baurrous, Dethard. ap. willa, is well characterized by its long and large anthers, which it has in common 
only with the two last-mentioned species, aid its terete stem and leafless vagine. Originally found on the shores of 
the Baltic, it has been traced to those of northwestern Europe and to our northeastern coasts from Newfoundland to 
Massachusetts ; but here it leaves its seaside home and appears in several swamps in Lancaster county in the interior 
of Pennsylvania ; all along the great lakes it is a common plant, not unexpected, to be sure, as on their shores we mee 
with many other marine plants, such as Cakile, Lathyrus maritimus, Euphorbia ia en and others, while they 
are quite free from saline matter. Is it the ocean-like spray of the waves of these immense bodies of fresh water, is it 
the ever-varying sand-formation of the downs, which invites sea-strand plants, or are las the remnants of an ocean-
