Question: which genus contains more species, Silene or Pimelea?

full_context: Document 1: Melaleuca: Melaleuca is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of "Leptospermum"). They range in size from small shrubs that rarely grow to more than 1 m (3 ft) high, to trees up to 35 m (100 ft). Their flowers generally occur in groups, forming a “head” or “spike” resembling a brush used for cleaning bottles, containing up to 80 individual flowers. They are superficially like "Banksia" species, which also have their flowers in a spike, but the structures of individual flowers in the two genera are very different.
Document 2: 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 3: Cerastium: Cerastium is a genus of annual, winter annual, or perennial plants belonging to the family Caryophyllaceae. They are commonly called mouse-ear chickweed. Species are found nearly worldwide but the greatest concentration is in the northern temperate regions. There are about 200 species. A number are common weeds in fields and on disturbed ground.
Document 4: Cichorieae: The Cichorieae (also called Lactuceae) are a tribe in the plant family Asteraceae that includes 93 genera and more than 1600 sexually reproductive species and more than 7000 apomictic species. They are found primarily in temperate regions of the Eastern Hemisphere. Cichorieae all have milky latex and flowerheads that only contain one type of floret. The genera "Gundelia" and "Warionia" only have disk florets, while all other genera only have ligulate florets. The genera that contain most species are "Taraxacum" (Crepidinae subtribe) with about 1600 apomictic species, "Hieracium" with about 770 sexually reproducing and 5200 apomictic species, and "Pilosella" with 110 sexually reproducing and 700 apomictic species (both Hieraciinae). Well known members include lettuce, chicory, dandelion, and salsify.
Document 5: Psylliodes chrysocephala: Psylliodes chrysocephala or Psylliodes chrysocephalus, common name cabbage-stem flea beetle, is native to the United Kingdom, in particular the southern part of Britain. It is a pest that eats plants in the cabbage family, rapeseed plants, watercress, mustard and other crops.
Document 6: Mimulus: Mimulus is a plant genus in the family Phrymaceae, which was traditionally placed in family Scrophulariaceae. The genus now contains only seven species, two native to eastern North America and the other five native to Asia, Australia, Africa, or Madagascar. In the past, about 150 species were placed in this genus, most of which have since been assigned to other genera, the majority to genus "Erythranthe". "Mimulus
Document 7: Pimelea: Pimelea (often seen spelled "Pimelia", which is the name of a genus of beetles) is a genus of plants belonging to the family Thymelaeaceae. There are about 80 species in the genus, which is native to Australia and New Zealand. Many of the species are poisonous to cattle and horses.
Document 8: Silene menziesii: Silene menziesii is a species of flowering plant in the pink family known by the common names Menzies' campion and Menzies' catchfly. It is native to western North America from Alaska through the western half of Canada to the southwestern United States. It can be found in many types of habitat and it is quite common in much of its range. It is variable in morphology and there are a number of varied subtaxa. In general, it is a perennial herb growing from a caudex, appearing matlike, decumbent, or erect, with stems a few centimeters to over half a meter long. It is usually hairy in texture, with upper parts bearing sticky glandular hairs. The leaves are lance-shaped, oppositely arranged in pairs, and a few centimeters in length, upper leaves usually smaller than lower. Flowers may occur in a cyme at the top of the stem, or in leaf axils, or both. Each is encapsulated in a hairy, veined calyx of fused sepals. The petals are white with two lobes at the tips. The plant is dioecious with male and female plants producing different flowers. The male and female flower types look the same externally; the stamens are reduced in female plants and the stigmas are reduced in the male.
Document 9: Silene: Silene is a genus of flowering plants in the family Caryophyllaceae. Containing approximately 700 species, it is the largest genus in the family. Common names include campion (which is shared with the related genus "Lychnis") and catchfly. Many "Silene" species are widely distributed, particularly in the northern hemisphere.
Document 10: Sagina: Sagina (like "Colobanthus" called "pearlworts") is a genus of 20–30 species of flowering plants in the pink or carnation family, Caryophyllaceae. These are flowering herbs native to temperate regions of the Northern Hemisphere extending south to tropical mountain areas at high altitudes, reaching just south of the equator in Africa. They are small annual or perennial herbaceous plants, growing to 5–15 cm. The leaves are opposite, often in tight whorl-like clusters, simple linear, typically 5–20 mm long. The flowers are solitary or in small cymes, with four or five green sepals and an equal number of white petals; the petal size relative to the sepal size is useful in species identification. The fruit is a small capsule containing several seeds.
Document 11: Leucospermum: Leucospermum (Pincushion, Pincushion Protea or Leucospermum) is a genus of about 50 species of flowering plants in the family Proteaceae, native to Zimbabwe and South Africa, where they occupy a variety of habitats, including scrub, forest, and mountain slopes.
Document 12: Cyperaceae: The Cyperaceae are a family of monocotyledonous graminoid flowering plants known as sedges, which superficially resemble grasses and rushes. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "Carex" genus of "true sedges" with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands.
Document 13: 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 14: Pimpinella: Pimpinella is a plant genus in the carrot family; it includes the aromatic herb anise "(P. anisum)".
Document 15: Centaurea: Centaurea ( ) is a genus of between 350 and 600 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich. Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads" (common knapweed). The "Plectocephalus" group – possibly a distinct genus – is known as basketflowers. "Cornflowers" is used for a few species, but that term more often specifically means "C. cyanus" (sometimes also called "basket flower"). The common name "centaury" is sometimes used, although this also refers to the unrelated plant genus "Centaurium".
