Question: Which of these is in the Apiaceae family, Ostrowskia or Selinum?

Context paragraphs:
Falcarindiol: Falcarindiol is a polyacetylene found in carrot roots which has antifungal activity.  Falcarindiol is the main compound responsible for bitterness in carrots.  Falcarindiol and other falcarindiol-type polyacetylenes are also found in many other plants of the Apiaceae family, including some commonly used seasonings such as dill and parsley.  A variety of bioactivities have been reported so far for falcaridiol and the falcarindiol-type polyacetylenes, and because of potential health-promoting metabolic effects these compounds are studied as potential nutraceuticals.  It is the most-active among several polyynes with potential anticancer activity found in Devil's Club ("Oplopanax horridus"), a medicinal plant used by many indigenous peoples in Alaska and the Pacific Northwest.

Bupleurum: Bupleurum is a large genus of annual or perennial herbs or woody shrubs, with about one hundred and ninety species, belonging to the Apiaceae family.  The full size of its species may vary between a few cm to up to 3 m high.  Their compound umbels of small flowers are adorned with bracteoles that are sometimes large and may play a role in attracting pollinators.  Rare among Apiaceae are the simple leaves, bracts (if present) and bracteoles.  The genus is almost exclusively native in the Old World Northern Hemisphere, with one species native to North America and one species native to southern Africa.

Perideridia gairdneri: Perideridia gairdneri is a species of flowering plant in the carrot family known by the common names common yampah and Gardner's yampah.  It is native to western North America from southwestern Canada to California to New Mexico, where it grows in many types of habitat.  It is a perennial herb which may approach 1.5 meters in maximum height, its slender, erect stem growing from cylindrical tubers measuring up to 8 centimeters long.  Leaves near the base of the plant have blades up to 35 centimeters long which are divided into many narrow, subdivided lobes.  Leaves higher on the plant are smaller and less divided.  The inflorescence is a compound umbel of many spherical clusters of small white flowers.  These yield ribbed, rounded fruits each a few millimeters long.  This was an important food plant, even a staple food, for many Native American groups, including the Blackfoot, Paiute, Cheyenne and Comanche It would seem certain that the term "yampa" would be a version on the Comanche name for the tuber, variously yap, and yampa.  One of the main divisions of the Comanche, the Yapainuu, were named the yap eaters, whose chief was the famous Ten Bears.  More commonly referred to as the Yamparikas, this division roamed in the Northern Oklahoma area in historic times. .  The tuberous roots could be eaten like potatoes, roasted, steamed, eaten fresh or dried, made into mush or pinole, used as flour and flavoring, and were also used medicinally.  The danger of collecting and eating wild members of the carrot family (Apiaceae family, also known as Umbelliferae family) can not be overstressed.  The deadly plants water hemlock and poisonous hemlock are in this family and have a similar appearance to the edible species.

Selinum: Selinum is a genus of flowering plant in the family Apiaceae.

Selinum carvifolia: Selinum carvifolia is a flowering plant of the genus "Selinum" in the family Apiaceae.  The specific name "carvifolia" signifies 'having leaves resembling those of Caraway'.

Conioselinum: Conioselinum is a genus of flowering plant in the Apiaceae family, native to Eurasia and North America.  It has 10 species.  These are erect perennial plants with deeply toothed compound leaves and umbels of white flowers.  Plants of this genus are known commonly as hemlock-parsley.

Angelica archangelica: Angelica archangelica, commonly known as garden angelica, wild celery, and Norwegian angelica, is a biennial plant from the Apiaceae family, a subspecies of which is cultivated for its sweetly scented edible stems and roots.  Like several other species in Apiaceae, its appearance is similar to several poisonous species ("Conium", "Heracleum", and others), and should not be consumed unless it has been identified with absolute certainty.  Synonyms include "Archangelica officinalis" Hoffm., and "Archangelica officinalis" "var."  "himalaica" C.B.Clarke.

Selinum tenuifolium: Selinum tenuifolium is a flowering plant of the genus "Selinum" in the family Apiaceae.

Eryngium giganteum: Eryngium giganteum, with the common name Miss Willmott's ghost, is a species of flowering plant in the Apiaceae family.

Ostrowskia: Ostrowskia is a genus of plants in the Campanulaceae.  There is only one known species, Ostrowskia magnifica, native to the Central Asian nations of Afghanistan, Kyrgyzstan and Tajikistan.
