Diagnosis

Reference	Diagnosis
J. M. Anderson et al. 2007	Gymnospermous plants bearing ovules with a flask-shaped pollen chamber terminated by an elongate neck (salpinx/lagenostome/ nucellar-beak) and that are supplied by a single vascular system. Foliage: Frond-like with proximal dichotomy of primary rachis.
