Which genus of plants contains a larger variety of species, Paulownia or Dendromecon?
Paulownia Paulownia is a genus of six to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, related to and sometimes included in the Scrophulariaceae. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. They are deciduous trees 12 – tall, with large, heart-shaped leaves 15–40 cm across, arranged in opposite pairs on the stem. The flowers are produced in early spring on panicles 10–30 cm long, with a tubular purple corolla resembling a foxglove flower. The fruit is a dry capsule, containing thousands of minute seeds.
Sinningia speciosa Sinningia speciosa, commonly known in the horticultural trade as Gloxinia, is a tuberous member of the flowering plant family Gesneriaceae. The common name has persisted since its original introduction to cultivation from Brazil in 1817 as "Gloxinia speciosa". The name florist's gloxinia is sometimes used to distinguish it from the rhizomatous species now included in the genus "Gloxinia". Another common name is Brazilian gloxinia. The plants produce large, velvety, brightly colored flowers and are popular houseplants. Cultural requirements are similar to those of African violets except that "S. speciosa" generally requires more light and often has a dormant period, when the tuber should be kept cool and dry until it resprouts.
