ANATOMY OF CORTEX AND SECONDARY PHLOEM OF ROSACEAE. 14. COLEOGYNE AND KAGENECKIA

摘要

The bark anatomy of Coleogyne ramosissima shows its remote affinity to Kerrieae, though some common characters especially with bark of Rhodotypos are revealed. It does nbi confirm erecting subfamily Coleogyno-ideae because shared characters are numerous to arrange Coleogyne nearby Cercocarpus Kageneckia sharply contrasts with Quillaja in its bark pattern and bears similarities to Vauquelinia species of tribe Lindleyeue from subfamily Maloideae. It differs, however, from all members of the subfamily in casual simple sieve plates. The difference interferes with its inclusion into anyone recognised maloid's tribe and makes the genus to be held as aberrant member of the subfamily.
