D. laciniata. W. Stem is scarcely as high as the other, and
sends off 3 ternate leaves, or 3 leaves divided into 3 segments,
linear, and somewhat toothed, with reddish white flowers in a
raceme ; grows in woods, and flowers in May.
Both these are rather beautiful plants.
L unaria. L . 14. 1.
Two species are cultivated for their flowers ; one bears its fruit
in a flat, oval, or roundish pod,, of singular appearance, and an
inch in diameter ; flowers bluish and purple.
I b e r is . L. 14. 1. Candy Tuft.
A species wfith whitish flowers has been long cultivated as edging
for aisles in gardens and walks. Another beautiful variety,
with purple flowers, is becoming common. Native of Spain,
Tuscany, &c. So called from Iberia, the ancient name of Spain.
A rabis. L. 14. 2.
Five species are credited to this State.
A. falcata, M i., which is A. Canadensis, L ., is named from
the shape of its pod, flat and curved like a scythe, and called
Sicklepod. Stem 2 or more feet high, round and small, with
sessile leaves ; flowers in woods, in June.
A. rhomboidea. Ph., has fine rhomboid leaves on the stem,
and heart-shaped ones at the root ; flowers white ; grows on wet
meadows, Roxbury. Blossoms in May ; root tuberous and farinaceous.
Big.
A. hastata. L. Hairy Tower Mustard ; has the general appearance
of common mustard, though it is a much smaller plant.
A. thaliana. L. Wall Cress; is a small plant about six
inches high, branched; radical leaves on petioles; stem leaves
sessile and few ; flowers white in a corymb ; on hills, and blossoms
in May.
Of the other species, A. hirsuta, Sm., there is some doubt,
which cannot be solved at present.
I satis. L . 14. 1.
I. tinctoria. L. Woad, so valuable for its blue coloring
matter ; is supposed to be little cultivated in this State, The
leaves at the root are crenate, on the stem arrow-form. Named
from the Greek, to render equal, from its supposed power to
smooth the roughness of the skin. Used to color the skin of the
ancient Britons and Piets, from which they were named. Loudon.
H e s p er is . L . 14. 2.
II. matronalis. L. Garden Rocket. A fine plant in the
gardens, and, when its flowers become double, it is thought quite
handsome ; a native of Lake Huron, and sometimes called
Dame’s Violet.
H. tristis. L. Yellow Rocket, is less cultivated than the
other ; stem hispid and branched ; flowers handsome.
The genus is named from the Greek for evening, as the flowers
are then more fragrant. Loudon.
ORDER 10. FUMARIACEÆ. F umitory T r ib e .
Two deciduous sepals ; 4 cruciate petals, sometimes so united
as to appear one, or only 2 united, cohering at the apex, and.
inclosing the anthers_and stigma ; stamens 6, often in 2 sets,
rarely separate ; ovarium superior, and one-celled ; leaves much-
divided, often having tendrils, commonly alternate ; herbaceous.
The plants have not much odor, but a watery and not milky
juice, and are said to be diaphoretic and aperient ; but they are
not used for thèse properties. Only a few genera, and not numerous
species, belong to this order, and these are scattered over the
northern temperate zone.
The fecundation of the Fumariaceæ shows special contrivance.
While the anthers are confined by the corolla, and the pollen seems
unable to reach the style, the stigma projects two blunt horns,
one of which passes to each of the two sets of anthers, so as to
secure the pollen as it exudes from the anther, or is forced out by
the contractions of the anther.
