A composite stem is made up from two or more recognised stem forms, e.g. plain stem & opaque twist stem, opaque twist stem & air twist stem or knops, air twist stem or knops & plain stem etc.
You can see various composite stem glasses in Bickerton starting on page 188. Composite Stems form a very small section of the overall 18th cen glass forms. Production levels were small and as such they are highly desirable and difficult to source.
Many composite stems are often misdescribed and a small 1-2cm plain stem section just below the bowl (required for joining the bowl to the stem) on a knopped air twist, most certainly does not make it a composite stem.
