M a t e r i a l. Oriolo MSF 675, 631, n.n.

D e s c r i p t i o n. Leaf, simple, petiolate, petiole> 20 mm long, lamina rhombic, 5-lobed, with three main and two smaller lobes, lamina 55–60 mm long, 70–75 mm wide, base truncate-shallowly cordate, lobes triangular, with a blunt acuminate apex, margin entire or with few hook-like teeth approaching small lobes, primary venation actinodromous, 5 primary veins, secondary venation brochidodromous.

R e m a r k s. Acer lobelii belongs to a clade of maples (several subspp. of A. cappadocicum ranging from Italy to Asia Minor, the Himalayas and East Asia). Within western Eurasia, modern species (subspecies) of A. cappadocicum is thought to have appeared in the Pleistocene, based on the inferred divergence time for A. campestre and A. platanoides L., 1753 ( Renner et al. 2008).
