NORTH AMERICAN SPECIES OF JUNCUS. 278 
peduncle is really terminal and bears the earliest flowers, the lowest axillary one is the next in the progress of develop- 
ment, and then follow the others in ascending order, so that the one next to the terminal one bears the latest flowers ; 
in the smaller specimens the leaves of the main stem, and consequently the peduncles, are alternating, or in 4 order. 
a. is the largest one with a remarkably long style, about 3 times as long as the ovary, and much exceeding 
the sepals and the very long anthers ; its seeds, however, are among the smallest of the species. Var. 8. is inter- 
mediate in size between both others; when the heads bear 2 flowers, these are arranged exactly like those of J. pelo- 
carpus, with 2 lower bracts, bearing the flowers in their axils, and a third sterile one at a inner base of the upper 
flower ; sometimes this upper flower is dimerous. Var. y. is the smallest one, only 3-1 inch high ; its single flowers 
have 2 bracts at their base, just as those of any other meena poner Juncus, and eiehiibties ane - exterior sepals, 
the stamens, carpels, and stigmas ; the inner sepals and the valves of the capsule are opposed to

Sandy soil in San Francisco, in flower and fruit in April, Dr. Albert Kellogg, for whom as the — = modern 
Californian botany, which he investigated and elucidated, at first unaided and struggling with numerous imp 
ments, this plant has been named. — Nearly allied to the last but differing in many striking spe this ile [495] 
species represents a glomerule of a few lines in diameter, pushing out in all directions a number read-] 
leaves ; these are 6-10 lines long, and }~-} line wide ; the short terminal heads are quite loose, Stila on such 
distinct peduncles that one would be inclined to consider them as single, if the pair of bracts were not wanting which 
always surround the base of single flowers in this genus ; the lowest axils of a branch often produce longer peduncles, 
elevated above the glomerate mass, but shorter than the leaves, and bearing small heads, usually of two flowers only. 
Flowers pale green and whitish, and, especially the capsule, of very delicate structure, 13-2 lines long ; seeds 0,25 line 
long, 15 diameters equal to the length, similar to the seeds of the last species, but with much more prominent dark 
ribs, 4 of which are visible on the side.

J. aie Add : capsula sepala subeequante ; seminibus lanceolato-ovatis epidermide plus minus producta sub- 
caudatis irregulariter costato-reticulatis, areis elongatis levibus. — Sandy soil near San Francisco, Kellogg, Bolander, 
Hb. norm. a _— . seeds 0.35-0.40 line long, length equal to 2 or 24 diameters; tips slightly or rarely considerably 
elongated, or the upper one wanting; surface | palis ish and mt with a thick ‘rather loose epidermis, the cells of 
which erable with the reticulation of the seed.— A form from the mouth of the Columbia, Douglas, communi- 
eated by Dr. Hooker, has an obtuse capsule and thick ovdid seeds. — The differences between this and what I have 
named J. Tasmanicus (p. 453, note) seem to be almost too slight to be of specific value. 
Mr. Bolander sends from sphagnous swamps near Mendocino, California, a form which may be distinguished as 
var. paniculatus ; analogous to the paniculate forms of J. pheocephalus and others ; the heads of the simple or some- 
. what compound panicle are about 5-flowered ; Hb. norm. 41, not yet in bloom in May; no stipular appendages at the 
base of the leaves. Maturer specimens would be desirable.

Near the Big Tree Grove, Mariposa, California, growing in large tufts, 2-3 feet in diameter, on the ‘ted [496] 
banks of streamlets, alt. 6,500 feet, H. Bolander, flowers in July. — In many respects intermediate betw he 
Pipe and the following species, this plant is distinguished from both by its small obtuse flowers, 2s with light 
| margins (1}, or in fruit nearly 2 lines long), the elongated obtuse capsule, and above all by the distinctly 
se re almost obtuse seeds, which in both others are more or less pointed or even tailed and differently marked ; 
the seeds I could examine, not quite mature, are 0.25 line long and half as much in diameter, and exhibit 8 ribs on 
one side ; their arez are apparently smooth. 
J. longistylis, also on the Red River of the North, Hubbard in Hb. Lapham; Huerfano hdaagy of the Rocky 
Mountains, Parry; on the banks of Mono lake in the Californian mountains, Bolander, Hb. norm. 43. — Stem with 
several short leaves, always considerably exceeding the linear foliage ; seeds apiculate or uae pa ees with a 
distinct white rhaphe, strongly ribbed, when not a mature like those of J. marginatus; fully ripe seeds with 
very slight cross-bars and a faint transverse lineolati
