BignoniaceaeLamiales version of Asterids with•opposite, compound leaves•seeds with wings of hair
Catalpa - North American Bignoniaceae
BIGNONIACEAE (LAMIALES, EUASTERIDS I)
NUMBERS: 100 Genera, 800 species
GEOGRAPHY: mainly tropical, best developed in tropical America
HABITAT: various; commonest in drier, lower forests
ASTERIDAE CHARACTERS: fused petals, two carpellate gynoecium, stamens equal to
or fewer than petals, adnate to petals, disk present
LAMIALES CHARACTERS: leaves opposite, bilaterally symmetrical flowers with
stamens fewer than corolla lobes, superior ovary, fruit a capsule
CHARACTERS DIAGNOSTIC OF FAMILY:
Habit woody: trees or lianas (there are an awful lot of lianas)
Leaves compound (or rarely simple) and usually opposite; tendrils when present aretransformed leaf tips
Flowers large and colorful (or poorly colored in bat-pollinated Crescentia, Enallagma)
Gynoecium stigmas, sensitive to touch, close together to conceal receptive portion;
ovules many per carpel
Fruit usually an elongate capsule dehiscing to yield seeds with hairs matted into a wing;
anomalous spherical, indehiscent fruits in Crescentia and Enallagma have fleshy
hairs
Tabebuia - common in drier neotropics
Spathodea - ubiquitous ornamental
Lianas area common in the Bignoniaceae.
Cydistus
Anisostichus
anomalous wood in the lianas
Crescentia - the calabash
Kigelia - the sausage tree of Africa
