| Species which have not fallen under our observation.
* Shriibby.
26. 77. elatum (Ait.) : trigynous; sepals lanceolate-ovate, acute ; stamens
longer than the corolla; stem shrubby ; leaves ovate-oblong. Ait, Kew. (ed.
1.) 3. p. 104.
The H. elatum figured by Jussieu (in ann. mus. 3. t. 17.), is probably different
from Aiton’s plant, and is doubtless not a native of North America.
27. 17. fastigiatum (Ell.).: branches somewhat compressed; leaves narrowly
lanceolate, very acute ; corymbs terminal, many-flowered, fastigiate
styles united. Ell. sk- 2. p. 31, not of 77. B. <$■ K.
Pine barrens of Scriven county, Georgia. May-July.—Shrub 3 feet high.
Leaves about 3 inches long, tapering yet connate at the base. Corymbs
with solitary flowers nearly sessile in the lower divisions. Styles not separating
as the pod matures. Elliott.—We have no specimens which agree
with this description.
, * * Herbaceous.
28. 77. Icevigatum (Ait.) : trigynous; leaves ovate, somewhat clasping; sepals
ovate, acute; panicle trichotomous, the intermediate flower sessile. Ait.
Kew. (e<Z. 1.) 3. p. 106.
Referred by Willdenow and most succeeding authors to H. nudiflorum;
but the dichotomal flowers in that species are not sessile. Perhaps H. angu-
losum, or H. ellipticum.
29. 77. sessiliforum (Spreng.): trigynous; branches terete; leaves half-
clasping, cordate-oblong, veinless, punctate ; corymb terminal, with the flowers
nearly sessile; sepals oblong, acute, foliaceous, much longer than the corolla
; styles united. Spreng. syst. 3. p. 346.
Described from a specimen in Willdenow’s herbarium. Probably H. myr-
tifolium.
30. 77. virgatum (Lam.): stem straight, 4-angled; leaves ovate-lanceolate
slightly clasping, punctate with black dots, revolute on the margins ; panicle
dichotomous, few-flowered ; sepals lanceolate; styles 2-3; stigmas capitate.
D C—Lam. diet. 4. p. 158; DC. prodr. 1. p, 547.
31. 77. cistifolium (Lam.): stem angular; leaves ovate-oblong, rather
acute somewhat clasping, punctate with black dots beneath, revolute on the
margins ; flowers in dichotomous corymbs; sepals ovate ; styles united. DC.
1. c.—Lam. diet. 4. p. 158.
32. 77. hedyotifolium (Poir.): stem straight, 4-angled; leaves sessile, decussate
lanceolate, rather acute, appressed, not pellucid-punctate, but with
black dots beneath; sepals linear-lanceolate, with black dots; styles 3-4;
stigmas capitate. DC. 1. c.—Poir. diet. 7. p. 700.
Doubtless H. angulosum.
33. 77. triplinerve (Vent.): stem herbaceous, 3-angled, decumbent at the
base - leaves linear, much spreading, obtuse, with revolute margins; sepals
ovate acute; petals unequal. DC.— Vent.hort. Cels. t. 58; DC. prodr. 1.
^ On the banks of the Ohio, Michaux, ex Vent.—We have not seen the
fionre and original description of this species ; but the character given by
Pursh which Is apparently taken from Ventenat, includes several important
particulars not mentioned by Choisy; whose elaboration of the' species of
Hypericum in De Candolle’s Prodromus is far from satisfactory. The stem
is said by Pursh to be erect, the leaves triplinerved, the flowers as large as in
H. perforatum, and the sepals and petals glandulose-serrate.
34. 77. anagalloides (Cham. & Schlecht.) : stem herbaceous, procumbent
and creeping; leaves ovate, obtuse, 5- 7-nerved, very minutely pellucid-punctate;
cyme terminal, leafy, few-flowered, not glandulose; sepals obovate,
shorter than the corolla; capsule..........; stamens 15-20, distinct; styles 3,
distinct. Cham. <§■ Schlecht. in Linncea, 3. p. 127.
St. Francisco, California.—Leaves membranaceous, 5-7-nerved ; the largest
about 6 lines long ; the lower ones much smaller. Dichotomal flowers pe-
duncled. Cham. <f- Schlecht— Allied to H. humifusum, according to the
authors cited; and apparently also to H. mutiium.
35. 77. acutifolium (Ell.) : stem herbaceous?, branching, glabrous; leaves
narrowly lanceolate, acute; panicle many-flowered; capsules scarcely longer
than the calyx. Ell. sk. 2. p. 26.
Milledgeville, Georgia, Dr. Boykin.—Resembles most the H. Canadense,
but larger in every respect: it differs also in its acute leaves, proportionally
short capsule, and much more compact panicle. Elliott.
H. rostratum, Raf. fl. Ludov.
II. fulgidum, Raf. fl. Ludov.
3. ELODEA. Adans.; Nutt. gen. 2. p. 17; Spach, in ann. sci. not.
(ser. 2.) 5. p. 165, not of Michx.
Triadenium, Raf. Species of Hypericum, Linn. tpc.
Sepals 5, equal, somewhat united at the base. Petals 5, deciduous, equilateral.
Stamens 9 (rarely 12—15)j triadelphous; the parcels alternating with
3 hypogynous glands. Styles 3, distinct. Capsule oblong, membranaceous,
3-celled: the placeritee somewhat cohering in the axis, at length separating
from the valves.—Perennial glabrous or slightly glaucous herbs. Leaves
membranaceous, pellucid-punctate, and often with a few black dots (the axils
never leafy). Cymules few-flowered, terminal and in the axils of the
upper leaves, pedunculate or subsessile : flowers dull orange-purple.
Spach has very well characterized this genus; but we have been obliged to reduce
his seven species to two.
1. E. Virginica (Nutt.) : leaves sessile, clasping; stamens united below
the middle.—Nutt. ! gen. 2. p. 17 ; Ell. sk. 2. p. 33 ; Spach, l. c. E. cam-
panulata, Pursh, fl. 2. p. 379. E. Drummondii & Fraseri, Spach, l. c.
Hypericum Virginicum, Linn. ; Michx. fl. 2. p. 81; Andr. bot. rep. t. 552;
DC. prodr. 1. p. 546 ; Bigel. fl. BoSt. p. 281; Darlingt. fl. Cest.p. 322.
H. campanulatum, Walt. Car. p. 191.
Swamps, Canada to Florida 1 and Louisiana! July-Aug.—Plant 1-2
feet high, often of a purplish hue. Stem nearly terete, branching. Leaves
oblong, 1-2 inches or a little more in length, somewhat glaucous underneath.
Axillary cymes mostly about 3-flowered ; the terminal one often compound.
Petals obovate-oblong, nearly twice the length of the calyx, marked with
reddish veins. Stamens rarely 12 or more, always triadelphous; the filaments
seldom united more than one-third of their length, shorter them the petals.
Glands ovate, orange, secreting a copious sweetish fluid. Capsule obscurely
triangular, nearly twiee the length of the calyx when mature, rather
acute. Seeds oblong, very numerous.
