Question: Which genus has more species, Brunfelsia or Alocasia?

Context paragraphs:
Brunfelsia plowmaniana: Brunfelsia plowmaniana is a species of flowering plant of the nightshade family that is native to the cloud forests of the Bolivian and Argentinian Andes.  It was first described in 2012 on the basis of systematic DNA barcoding of specimens from the genus "Brunfelsia".  Specimens belonging to the new species had previously been placed in the polymorphic species "B. uniflora", which a molecular phylogeny revealed as polyphyletic.

Alocasia: Alocasia is a genus of broad-leaved rhizomatous or tuberous perennials from the family Araceae.  There are 79 species native to tropical and subtropical Asia to Eastern Australia, and widely cultivated elsewhere.

Brunfelsia: Brunfelsia is a genus of flowering plants in the family Solanaceae, the nightshades.  There are about 50 species described.  Linnaeus named the genus for the early German herbalist Otto Brunfels (1488–1534).  Common names for the genus include raintree.

Xanthosoma: Xanthosoma is a genus of flowering plants in the arum family, Araceae.  The genus is native to tropical America but widely cultivated and naturalized in other tropical regions.  Several are grown for their starchy corms, an important food staple of tropical regions, known variously as "malanga", "otoy", "otoe", cocoyam (or new cocoyam), "tannia", "tannier", "yautía", "macabo", "ocumo", "macal", "taioba", "dasheen", "quequisque", "ʻ ape" and (in Papua New Guinea) as Singapore taro ("taro kongkong").  Many other species (including especially "X. roseum") are used as ornamental plants, and in popular horticultural literature are known as ‘ape or elephant ear (from the purported resemblance of the leaf to an elephant's ear), although the latter name is sometimes also applied to members with similar appearance and uses in the closely related genera "Caladium", "Colocasia" (i.e., taro), and "Alocasia".
