description
D e r i v a t i o n o m i n i s. From the Taimyr Peninsula.
diagnosis
D i a g n o s i s. Long racemose aggregation forming cone or megastrobilus consisting of axis with peltate seed-bearing discs (which also can be interpreted as seed-bearing semiclosed capsules) with margins curved adaxially; disc round to ovoid, with short stalk connected at central adaxial part and attached to cone axis nearly perpendicularly in dense spiral pattern. Six to eight seeds concentrically displayed around stalk on adaxial surface of disc. Seeds platyspermic, ovoid, narrower at their apical micropylar end orientated toward disc stipe. C o m p a r i s o n. The new genus differs from other closely related angaropeltian peltasperms (the genera Angaropeltum DOWELD, Sylvocarpus NAUGOLNYKH, Permoxylocarpus NAUGOLNYKH) in the ovoid shape of the disc orientated across the megastrobilus / cone axis.
