SERIES II. SYMPETALAE. Perianth in higher stage of 
development, always originally in 2 whorls, the inner gamophyllous 
(in a few’’ cases polyphyllous or absent, though normal in closely 
related forms). 
A. Polypetalous corollas, as well as sympetalous, occur, 2 whorls 
of sta. or one. Hypogyny the rule, rarely epigyny. 
Cohort 1. Ericales (fir. 5 — 4-merous, obdiplostemonous, or the sta. 
before the petals absent, $, usually regular; C or (C); sta. hypo- or
