Question: Which genus includes more plants that produces flowers, Zanthoxylum or Legousia?

Context paragraphs:
Early Girl: The Early Girl tomato is a medium-sized globe-type F1 hybrid popular with home gardeners because of its early ripening fruit.  Early Girl is a cultivar of tomato with indeterminate growth, which means it produces flowers and fruit until it is killed by frost or another external factor (contrast with a "determinate" cultivar, which would grow to a limited, predefined shape and be most productive for one large harvest before dying or tapering off with minimal new growth or fruit).  It grows tall, therefore it needs support as the plant grows.  Fruit maturity ranges from 50 to 62 days after transplanting, depending on the source, which appeals to growers in climates with shorter growing seasons.  Early Girl can tolerate temperatures as low as 40 F and is well-suited to hot, dry climates.  Early girl is reliable and prolific.

Legousia: Legousia (Venus' looking glass) is a genus of flowering plants in the Campanulaceae (bellflower) family.

Zanthoxylum: Zanthoxylum (including genus "Fagara") is a genus of about 250 species of deciduous and evergreen trees and shrubs in the citrus or rue family, Rutaceae, native to warm temperate and subtropical areas worldwide.  Several of the species have yellow heartwood, to which their generic name alludes.

Chylismiella: Chylismiella pterosperma is a species of evening primrose known by the common name wingfruit suncup and is the only species in the monotypic genus Chylismiella.  It is native to the western United States, where it grows in several habitat types, including sagebrush.  It is a slender annual herb producing an erect stem up to about 14 centimeters in height.  The leaves are up to 3 centimeters long and densely coated in bristly hairs.  The nodding inflorescence produces flowers with white petals each less than 3 millimeters long.  They are sometimes yellow near the bases and fade to a purple color as they wither.  The fruit is a straight capsule about 1 to 3 centimeters long with a thick wing down the middle.

Anadenanthera colubrina: Anadenanthera colubrina (also known as vilca, huilco, huilca, wilco, willka, curupay, cebil, or angico) is a South American tree closely related to Yopo, or "Anadenanthera peregrina".  It grows to 5-20 m tall and the trunk is very thorny.  The leaves are mimosa-like, up to 30 cm in length and they fold up at night.  In Chile, "A. colubrina" produces flowers from September to December and bean pods from September to July.  In Brazil "A. colubrina" has been given "high priority" conservation status.

Gastrodia kuroshimensis: Gastrodia kuroshimensis is an unusual species of plant that was discovered in April, 2016.  It is mycoheterotrophic, meaning that it does not engage in photosynthesis like most plants but obtains energy from its host fungi.  It is also cleistogamous, meaning that it produces flowers that never bloom.  Since its flowers never bloom, it is self-fertilizing.

Indeterminate growth: In biology and botany, indeterminate growth is growth that is not terminated in contrast to determinate growth that stops once a genetically pre-determined structure has completely formed.  Thus, a plant that grows and produces flowers and fruit until killed by frost or some other external factor is called indeterminate.  For example, the term is applied to tomato varieties that grow in a rather gangly fashion, producing fruit throughout the growing season, and in contrast to a determinate tomato plant, which grows in a more bushy shape and is most productive for a single, larger harvest, then either tapers off with minimal new growth/fruit, or dies.

Zanthoxylum psammophilum: Zanthoxylum psammophilum (synonym Fagara psammophila Aké Assi) is a species of shrub or small tree in the Rutaceae family.  It is a large liana endemic to Côte d'Ivoire, although in 2005 it was found in Liberia as well.  "Zanthoxylum psammophilum", a new combination created in 1975 to subsume the genus "Fagara" into the genus "Zanthoxylum" based on morphology and secondary metabolites, is the preferred name according to the Conservatoire et Jardin botaniques de la Ville de Genève which has a section that specializes in the conservation and biodiversity of flowering plants of Côte d'Ivoire.  However, the International Plant Names Index lists "Fagara" as the genus, and "Zanthoxylum" as the synonym.  The type specimen for the plant was collected in the ecotone between the lowland Eastern Guinean forests (tropical rainforest) and the inland Guinean forest-savanna mosaic in the Lagunes District.

Saltugilia caruifolia: Saltugilia caruifolia (syn.  "Gilia caruifolia") is a species of flowering plant in the phlox family known by the common names carawayleaf gilia and caraway-leaved woodland-gilia.  It is native to the Peninsular Ranges of southern California and northern Baja California, where it grows in local habitat types such as chaparral.  This herb produces a thin stem 12 centimeters to about a meter long.  The leaves are up to 8 centimeters long at the base of the plant and divided into many finely subdivided lobes.  The top of the stem branches into an inflorescence dotted with many glands.  It produces flowers with lavender lobes dotted with darker purple near the bases.

Spartina alterniflora: Spartina alterniflora, the smooth cordgrass, saltmarsh cordgrass, or salt-water cord grass, is a perennial deciduous grass which is found in intertidal wetlands, especially estuarine salt marshes.  It grows 1 - tall and has smooth, hollow stems which bear leaves up to 20-60 cm long and 1.5 cm wide at their base, which are sharply tapered and bend down at their tips.  Like its relative saltmeadow cordgrass "S. patens", it produces flowers and seeds on only one side of the stalk.  The flowers are a yellowish-green, turning brown by the winter.  It has rhizoidial roots, which, when broken off, can result in vegetative asexual growth.  The roots are an important food resource for snow geese.  It can grow in low marsh (frequently inundated by the tide) as well as high marsh (less frequently inundated), but it is usually restricted to low marsh because it is outcompeted by saltmeadow cordgrass in the high marsh.  It grows in a wide range of salinities, from about 5 psu to marine (32 psu), and has been described as the "single most important marsh plant species in the estuary" of Chesapeake Bay.  It is described as intolerant of shade.
