Division Magnoliophyta (formerly Phylum Tracheophyta)
Class Magnoliopsida (formerly Class Angiospermae)
Subclass Asteridae (formerly Subclass Dicotyledonae)
Convolvulaceae, the morning-glory
family, contains about 55 genera and 1700 species (600 of which appear
in a single genus, Ipomoea).
Convolvulaceae are distinctive because of their funnel-shaped flowers
made from five fused petals. The flowers have five stamens fused
to the petals. Most have a vine-like habit.
The division of this family into subfamilies and tribes appears to be
a bit confused at the moment; certainly there was little on the Web to
guide me. Adding to the confusion was that the tribe Convolvuleae,
which originally contained most of the family's genera, was recently elevated into
a subfamily (Convolvuloideae) with a much smaller tribe Convolvuleae
underneath it. For this reason, you will find may of the genera of
Convolvulaceae listed under tribe Convolvuleae where
they have been moved to a different tribe of Convolvuloideae.
- Tribe Argyreieae:
- Tribe Dichranostylidae:
- Tribe Erycibeae:
- Tribe Lepistemoneae:
I began this writeup a long time ago, and gave up after I discovered
how difficult the family's subdivision was. I have given up trying to make
this classification "perfect" and will make corrections when people suggest them
(references would be nice). Many of the sources are lost; however,
L. Watson and M. J. Dallwitz (1992 onwards). The Families of Flowering

was certainly one of them.
