Question: Of the genera Indigofera and Dasylirion, which has more species?
Context: Dasylirion is a genus of North American plants in the asparagus family, all native to Mexico, with the ranges of three species also extending into the southwestern United States.  In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Dasylirion leiophyllum is a species of flowering plant in the asparagus family known by the common names green sotol, smooth-leaf sotol, and smooth sotol.  It is native to North America, where it occurs in Chihuahua and Coahuila in Mexico and New Mexico and western Texas in the United States. Vogesella indigofera is a strictly aerobic, Gram-negative bacterium.  It is the sole species of the genus "Vogesella".  "V. indigofera" produces a blue pigment (indigoidine)and the colonies develop a metallic copper sheen upon extended incubation (greater than 24 hours).  This organism is not known to be pathogenic and is commonly found in freshwater. Indigofera is a large genus of over 750 species of flowering plants belonging to the family Fabaceae.  They are widely distributed throughout the tropical and subtropical regions of the world. Indigofera australis, known as Australian Indigo, is an attractive species of leguminous shrub in the genus "Indigofera" (Fabaceae family).  The genus name ""Indigofera"" is Neo-Latin for "bearing Indigo" (Indigo is a purple dye originally obtained from some "Indigofera" species), while "australis" from the Latin, means "southern", referring to the geographical distribution of the species. The Fabaceae or Papilionoideae, commonly known as the legume, pea, or bean family, is a large and economically important family of flowering plants.  It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit (legume) and their compound, stipulated leaves.  Many legumes have characteristics of flowers and fruits.  The family is widely distributed, and is the third-largest land plant family in terms of number of species, behind only the Orchidaceae and Asteraceae, with about 751 genera and some 19,000 known species.  The five largest of the genera are "Astragalus" (over 3,000 species), "Acacia" (over 1000 species), "Indigofera" (around 700 species), "Crotalaria" (around 700 species) and "Mimosa" (around 500 species), which constitute about a quarter of all legume species.  The ca. 19,000 known legume species amount to about 7% of flowering plant species.  Fabaceae is the most common family found in tropical rainforests and in dry forests in the Americas and Africa. Dipterocarpaceae are a family of 16 genera and approximately 695 known species of mainly tropical lowland rainforest trees.  The family name, from the type genus "Dipterocarpus", is derived from Greek ("di" = two, "pteron" = wing and "karpos" = fruit) and refers to the two-winged fruit.  The largest genera are "Shorea" (196 species), "Hopea" (104 species), "Dipterocarpus" (70 species), and "Vatica" (65 species).  Many are large forest emergent species, typically reaching heights of 40–70 m, some even over 80 m (in the genera "Dryobalanops", "Hopea" and "Shorea"), with the tallest known living specimen ("Shorea faguetiana") 93.0 m tall.  The species of this family are of major importance in the timber trade.  Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina, Indonesia and Malaysia.  The greatest diversity of Dipterocarpaceae occurs in Borneo.  Some species are now endangered as a result of overcutting, extensive illegal logging and habitat conversion.  They provide valuable woods, aromatic essential oils, balsam, resins and are a source for plywood. Indigofera heterantha (syn.  "Indigofera gerardiana"), commonly known as Himalayan indigo, is a species of flowering plant in the family Fabaceae.  It is native to the northwestern Himalayas of Tibet, in Asia. 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. Dasylirion longissimum, the Mexican Grass Tree, is a species of flowering plant native to the Chihuahuan Desert and other xeric habitats in Northeastern Mexico.
