Informal group Debeya sensu Krassilov, Lewy, Nevo, and Silantieva, 2005

Genera included: Debeya Miquel, 1853 ; Eudebeya Krassilov, 2005; Platydebeya Krassilov, 2005; Retrodewalquea Krassilov, 2005.

Species excluded from the Debeya group: Debeya pentaphylla (Velenovský, 1884) Knobloch, 1964 ; Debeya coriacea (Velenovský, 1884) Knobloch, 1964 .

Remarks.—The genus Debeya s.l. is probably heterogenous ( Krassilov 1979; Kvaček et al. 2001; Krassilov et al. 2005). A eudicotyledonous affinity of the Debeya group (with Debeya as restricted here) is inferred on account of compound architecture of the leaves.

The Cenomanian species Dewalquea pentaphylla Velenovský, 1884 and Aralia coriacea Velenovský, 1889 (both transferred to Debeya by Knobloch 1964) differ from the true Debeya (incl. Dewalquea ) in having “leaflets” of equal size, often inflated “petiolules” and in frequent occurrence of single “leaflets” ( Velenovský 1889; this is rather rare in the entire material described here). Probably they do not belong to the Debeya group.
