rarely spreading. Flowers 5-6 lines in diameter. Petals obovate, involute
when old. Stamens distinctly polyadelphous. Capsule as long as the sepals:
placentae a little introflexed. Seeds oval, finely striate longitudinally.
20. H. angulosum, (Miehx.) : stem acutely quadrangular, simple below,
corymbosely branched above; leaves oblong-lanceolate or subovate, acute,
closely sessile and somewhat clasping, nearly opaque, very obscurely dotted ;
cymes compound, naked, the ultimate branches bearing alternate distant
flowers; sepals unequal, ovate, acute; petals 3 times as long as the sepals,
obovate, with an angular tooth near the summit; styles distinct, nearly 3
times as long as the ovary; capsule ovate.—Miehx. fl. 2. p. 78 ; Pursh, fl.

Wet places in pine barrens, New Jersey! to Florida ! June-Aug.—Stem
1J-2 feet high, simple the greater part of. its length, often corymbosely
branched above. Leaves 8—12 lines long, rather thick, usually erect, indistinctly
veined, shorter than the internodes ; the upper ones sometimes
linear. Cymes often decompound, (occasionally reduced almost to a solitary
flower); the divisions appearing racemose from the abortion of one of the
forks at each subdivision of the cyme. Petals about half an inch long, cop-
peAcolored:. Capsule shorter than the calyx: placentae somewhat introflexed.
Seeds oval, smooth.—We have not restored Walter’s name to this
species, where it most probably belongs, as there is a H. denticulatum of
Kunth which has been long established.
21. II. ellipticum (Hook.): stem quadrangular, simple below; somewhat
branched at the summit; leaves elliptical, very obtuse, closely sessile, pellucid
punctate ; cyme nearly naked; sepals oblong, very unequal, 'spreading
; styles 3, connate nearly to the summit; capsule ovate-globose.—Hook,
fl. Bor.-Am. 1. p. 110. H. sphaerocarpon, Bart.! Jl. Philad. 2. p. 14; Nutt.!

Leaves an inch long, marked with obscure brownish dots, somewhat clasping
or a little narrowed at the base. Cyme usually few-flowered. Flowers
pale orange. Petals obovate, one-third longer than the sepals. Styles as
long as the ovary, separating when old : stigmas minute, subcapitate. Capsule
shorter than the calyx; the placentae somewhat introflexed. Seeds
oval, minutely striate and rugulose.
§4. Stamens 5-20, distinct: capsule 1-celled, with 3 strictly parietal
placentae: styles 3, distinct, short. Annual.
* Stem simple belaw, dichotomouslycymose above, with a (lichotomal (terminal) flower
■ in each division.
22. H. mutilum (Linn.): stem quadrangular, usually much branched;
leaves ovate-oblong, obtuse, clasping, 5-nerved, pellucid-punctate; cymes
leafv; sepals lanceolate, rather longer than the oblong petals ; stamens 6-12 ;
capsule ovate-conieal.—Linn. syst. 2. p. 511. H. quinquenervium, Halt.

Low grounds Canada! to Florida! and west to Arkansas! Texas,
Drummond! July-Sept.—Stem 6-12 inches high, slender, sometime?
nearly or quite simple. Leaves about § of an inch long, thin; lateral veins
obscure. Flowers very small; those in the forks of the cyme pedicellate.
Styles somewhat spreading: stigmas capitate. Capsule a little longer
than the calyx. Seeds cylindrical-oblong.—In specimens from Maryland
and Arkansas, the stem is nearly simple, the leaves more remote, and the
(iyme few-flowered; but they appear to be mere variations from the ordinary
form of the plant.
23. H. Canadense (Linn.): stem quadrangular, with erect branches;
leaves linear or linear-lanceolate, narrowed at the base, pellucid-punctate and
with black dots beneath ; sepals lanceolate, very acute, longer than the petals
and shorter than the oblong-conical capsule ; stamens 5-10. Willd. sp.

Wet places, particularly in sandy soils, Canada ! and Newfoundland, to
Georgia! June-Aug.—Stem 6-12 inches high, slender. Leaves usually
about an inch long and 1-2 lines wide; sometimes nearly lanceolate, obscurely
3-nerved. Sepals unequal. Petals oblong, orange. Styles shorter
than the ovary, (rarely 4 or 5) somewhat clavate: stigmas capitate. Capsule
very acute, usually about twice as long as the sepals. Seeds cylindrical,
yellow.
* * Stems rather rigid, dichotomously or irregularly much branched from near the
base: flowers distant and somewhat racemose on the branches: leaves subulate
or narrowly linear, oppressed. (Sarothra, Linn.)
24. H. Sarothra (Miehx.): stem and branches filiform, quadrangular;
leaves very minute, subulate, carinate ; flowers sessile; stamens 5—10; capsule
conical, elongated, twice the length of the linear-lanceolate sepals.

Sandy fields and road sides, Canada ! to Florida! and west to the Mississippi
! June-Aug.—Stem 4-10 inches high, appearing naked from the very
minute appressed leaves; branches slender and wiry, at first diverging, at
length nearly erect. Leaves 1-2 lines long, resembling stipules. Flowers
very minute. Petals oblong-linear, longer than the calyx. Styles spreading:
stigmas capitate. Capsule dark purple, very acute. Seeds extremely minute
oblong, yellowish; inner integument thick and slightly fleshy.—This plant is
without doubt a genuine Hypericum, although it is excluded from the genus
and from the order Hypericacea: by most botanists. The inner integument
is mostly thicker than usual, in this and the following species, so that it has
been mistaken by Gaertner and others for albumen.
25. H. Drummondii: stem and branches rather stout, terete below, quadrangular
above; leaves narrowly linear, longer than the internodes; flowers
pedicellate ; stamens 10-2 0 ; capsule ovate; shorter than the lanceolate sepals.
—Sarothra Drummondii, Grev. fl- Hook. 1. c. t. 107. f

! Arkansas, Dr. Pitcher! Dr. Leavenworth! Milledgeville, G or-
gia, Dr. Boykin! July-Sept.—Stem 10-18 inches high: the branches
almost always alternate. Leaves 6-S lines long, acute, marked with opaque
dots. Flowers 3 times as large as in the preceding species : pedicels 2-4 lines
long. S .pals unequal, shorter than the oblong petals. Capsule 2 4 lines
long. Seed 30-40, oval, about 10-ribbed, and transversely lacunose, 5 or 6
times as large as in H. Sarothra.
