Question: Which genus contains more species, Hippeastrum or Pittosporum?

full_context: Document 1: Pittosporum patulum: Pittosporum patulum is plant species endemic to New Zealand where it has a restricted distribution on South Island only ranging from Nelson, New Zealand in the north with occurrences in inland Marlborough down to Wanaka in the south. It is unusual amongst the genus in having deep red and scented flowers.
Document 2: 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.
Document 3: Leptospermum: Leptospermum is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of "Melaleuca". Most species are endemic to Australia, with the greatest diversity in the south of the continent but some are native to other parts of the world, including New Zealand and Southeast Asia. Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals. There is a single style in the centre of the flower and the fruit is a woody capsule. The first formal description of a leptospermum was published in 1776 by the German botanists Johann Reinhold Forster and his son Johann Georg Adam Forster, but an unambiguous definition of individual species in the genus was not achieved until 1979. Leptospermums grow in a wide range of habitats but are most commonly found in moist, low-nutrient soils. They have important uses in horticulture, in the production of honey and in floristry.
Document 4: Amaryllis: Amaryllis ( ) is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae). It is a small genus of flowering bulbs, with two species. The better known of the two, "Amaryllis belladonna", is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley to Knysna. For many years there was confusion among botanists over the generic names "Amaryllis" and "Hippeastrum", one result of which is that the common name "amaryllis" is mainly used for cultivars of the genus "Hippeastrum", widely sold in the winter months for their ability to bloom indoors. Plants of the genus "Amaryllis" are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name "lily" due to their flower shape and growth habit. However, they are only distantly related to the true lily, "Lilium".
Document 5: Pittosporum: Pittosporum ( or ) is a genus of about 200 species of flowering plants in the family Pittosporaceae. The genus is probably Gondwanan in origin; its present range extends from Australasia, Oceania, eastern Asia and some parts of Africa. "Citriobatus" is usually included here, but might be a distinct (though closely related) genus. They are commonly known as pittosporums or, more ambiguously, "cheesewoods".
Document 6: Metrosideros: Metrosideros is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the Myrtaceae family. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek "metra" or "heartwood" and "sideron" or "iron". Perhaps the best-known species are the pōhutukawa ("M. excelsa"), northern rātā ("M. robusta"), and southern rātā ("M. umbellata") of New Zealand, and "ʻ ōhiʻ a lehua", ("M. polymorpha"), from the Hawaiian Islands.
Document 7: Hibiscus: Hibiscus ( or ) is a genus of flowering plants in the mallow family, Malvaceae. The genus is quite large, comprising several hundred species that are native to warm-temperate, subtropical and tropical regions throughout the world. Member species are renowned for their large, showy flowers and are commonly known simply as hibiscus, or less widely known as rose mallow. The genus includes both annual and perennial herbaceous plants, as well as woody shrubs and small trees. The generic name is derived from the Greek word ἱβίσκος ("hibískos"), which was the name Pedanius Dioscorides ( 40–90) gave to "Althaea officinalis".
Document 8: Ceratopetalum: Ceratopetalum is a genus of nine species of shrub and tree in the family Cunoniaceae. They are found along the eastern coast of Australia and extend north to New Guinea. Two Australian species are among the best known, one being "C. apetalum" or coachwood, renowned as a timber tree, and "C. gummiferum", the New South Wales Christmas bush, so named as it flowers in December.
Document 9: Hippeastrum: Hippeastrum is a genus of about 90 species and over 600 hybrids and cultivars of perennial herbaceous bulbous plants. They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and large red or purple flowers.
Document 10: Bulbophyllum: Bulbophyllum is the largest genus in the orchid family Orchidaceae. With more than 2,000 species, it is also one of the largest genera of flowering plants, exceeded only by "Astragalus". This genus is abbreviated in the trade journals as Bulb. It is found throughout most of the warmer parts of the world: Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans.
Document 11: Boronia: Boronia is a genus of about 160 species of flowering plants in the citrus family Rutaceae, most are endemic in Australia with a few species in New Caledonia, which were previously placed in the genus "Boronella". They occur in all Australian states but the genus is under review and a number of species are yet to be described or the description published. Boronias are similar to familiar plants in the genera "Zieria", "Eriostemon" and "Correa" but can be distinguished from them by the number of petals or stamens. Some species have a distinctive fragrance and are popular garden plants.
Document 12: Cunonia: Cunonia is a genus of shrubs and trees in the family Cunoniaceae. The genus has a disjunct distribution, with 24 species endemic to New Caledonia in the Pacific, and one species (Cunonia capensis) in Southern Africa. Leaves are opposite, simple or pinnate with a margin entire to serrate. Interpetiolar stipules are often conspicuous and generally enclose buds to form a spoon-like shape (hence the common name "Butterspoon Tree" for "Cunonia capensis"). Flowers are bisexual, white, red (pink to purple), or green, arranged in racemes. The fruit is a capsule opening first around the base then vertically, seeds are winged.
Document 13: Pittosporum angustifolium: Pittosporum angustifolium (formerly Pittosporum phillyreoides) is a shrub or small tree growing in inland Australia. A slow growing plant, usually seen between two and six metres high, though exceptional specimens may exceed ten metres. Common names include Weeping Pittosporum, Butterbush, Cattle Bush, Native Apricot, Gumbi Gumbi, Cumby Cumby, Meemeei and Berrigan. It is drought and frost resistant. It can survive in areas with rainfall as low as 150 mm per year. A resilient desert species, individuals may live for over a hundred years. A revision of the genus "Pittosporum" re-instated this species the year 2000.
Document 14: Griffineae: The tribe Griffineae (in the family Amaryllidaceae, subfamily Amaryllidoideae) includes 2 genera with 22 species from South America which are actually endemic to Brazil. A typical character of the representatives of the tribe are the flowers - They are with blue or lilac color collected into an umbel. Only the members of this tribe and the genus "Lycoris" are able to form flowers with such color in the whole Amaryllidaceae family. The plants in this group are typical perennial flowers which are producing bulbs. The leaves are green, with elliptical form in the most of the cases but in some members as in "Worsleya" they are sword-shaped.
Document 15: Lilium: Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics. Many other plants have "lily" in their common name but are not related to true lilies.
