Question: Which genus contains roughly 75 species of trees and shrubs, Berberidopsis or Bunchosia?

Context paragraphs:
Bunchosia: Bunchosia is a genus in the Malpighiaceae, a family of about 75 genera of flowering plants in the order Malpighiales.  It contains roughly 75 species of trees and shrubs, which are native to dry woodlands, savannas, and wet forests.  Their range extends from Mexico and the Caribbean to southeastern Brazil and adjacent Argentina.  "Bunchosia" is one of three arborescent genera of Malpighiaceae with fleshy, bird-dispersed fruits.

Berberidopsis: Berberidopsis is a genus of flowering plants in the small family Berberidopsidaceae.

Theobroma: Theobroma is a genus of flowering plants in the mallow family, Malvaceae, that is sometimes classified as a member of Sterculiaceae.  It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America.  The generic name is derived from the Greek words θεός ("theos"), meaning "god," and βρῶμα ("broma"), meaning "food".  It translates to "food of the gods."

Hydrangea: Hydrangea ( ; common names hydrangea or hortensia) is a genus of 70–75 species of flowering plants native to southern and eastern Asia (China, Japan, Korea, the Himalayas, and Indonesia) and the Americas.  By far the greatest species diversity is in eastern Asia, notably China, Japan, and Korea.  Most are shrubs 1 to 3 meters tall, but some are small trees, and others lianas reaching up to 30 m by climbing up trees.  They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous.

Asteropeia: Asteropeia is a genus of flowering plants.  The genus contains 8 known species of shrubs and small trees, all endemic to Madagascar.  It is the sole genus in family Asteropeiaceae.  Members of the family are evergreen trees or shrubs.

Cinnamomum: Cinnamomum is a genus of evergreen aromatic trees and shrubs belonging to the laurel family, Lauraceae.  The species of "Cinnamomum" have aromatic oils in their leaves and bark.  The genus contains over 300 species, distributed in tropical and subtropical regions of North America, Central America, South America, Asia, Oceania, and Australasia.  The genus includes a great number of economically important trees.

Junonia: Junonia is a genus of nymphalid butterflies, described by Jacob Hübner in 1819.  They are commonly known as buckeyes, pansies or commodores.  This genus flies on every continent except Antarctica.  The genus contains roughly 30 to 35 species.

Privet: A privet is a flowering plant in the genus Ligustrum.  The genus contains about 50 species of erect, deciduous or evergreen shrubs, sometimes forming small or medium-sized trees, native to Europe, north Africa, Asia, many introduced and naturalised in Australasia, where only one species extends as a native into Queensland.  Some species have become widely naturalized or invasive where introduced.  "Privet" was originally the name for the European semi-evergreen shrub "Ligustrum vulgare", and later also for the more reliably evergreen "Ligustrum ovalifolium" used extensively for privacy hedging, though now the name is applied to all members of the genus.  The generic name was applied by Pliny the Elder (23–79 CE) to "L. vulgare".  It is often suggested that the name "privet" is related to "private", but the OED states that there is no evidence to support this.

Lippia: Lippia is a genus of flowering plants in the verbena family, Verbenaceae.  It was named after Augustus Lippi, (1678-1705), a French naturalist and botanist (with Italian origins).  He was killed in Abyssinia.  The genus contains roughly 200 species of tropical shrubs that are found around the world.  Plants are fragrant due to their essential oils, which vary between species but may include estragole, carvacrol, linalool, or limonene.  The leaves of certain species, such as "L. graveolens", can be used as a culinary herb similar to oregano.

Riedelia (plant): Riedelia is a genus of plants in the Zingiberaceae family.  The genus contains approximately 75 species that are distributed among New Guinea, the Solomon Islands, and Maluku Province in eastern Indonesia.  Among the described species is "Riedelia charontis", which was formally described in 2010.
