A phylogeny of Cariniana (Lecythidaceae) based on morphological and anatomical data.
Cariniana as previously circumscribed is a genus of 16 species restricted to neotropical forest habitats on well-drained sites. A phylogenetic analysis of the genus based on 33 morphological and anatomical characters was undertaken. The results show that Cariniana consists of two clades: the Allantoma/Cariniana decandra clade includes Allantoma lineata and seven species of actinomorphic-flowered Cariniana characterized by 5-merous flowers, carnose petals, incurved petal apex, flat calyxes, eucamptodromous secondary viens, percurrent tertiary venation, and not well developed areolation; and the C. legalis clade is made up of nine species characterized by an obliquely zygomorphic androecium, reticulate tertiary venation, and anomocytic stomata. The actinomorphic-flowered Cariniana are more closely related to the monotypic Allantoma lineata than they are to the species of C. legalis clade. In order to reflect these relationships, Cariniana is divided into two genera: species in C. legalis clade, which includes the generic type C. legalis, remain as Cariniana while species of Cariniana in the Allantoma/Cariniana decandra clade are transferred to Allantoma. The following new combinations are proposed: Allantoma decandra (Ducke) S. A. Mori, Y.-Y. Huang, & Prance, A. integrifolia (Ducke) S. A. Mori, Y.-Y. Huang, & Prance, A. kuhlmannii (Ducke) S. A. Mori, Y.-Y. Huang, & Prance, A. pluriflora S. A. Mori, Y.-Y. Huange & Prance, a nomen novum is coined for Cariniana multiflora Ducke because Allantoma multiflora is a synonym of Couratari multiflora (Sm.) Eyma, A. pachyantha (A. C. Sm.) S. A. Mori, Y.-Y. Huang, & Prance, A. pauciramosa (W. A. Rodr.) S. A. Mori, Y.-Y. Huang, & Prance, and A. uaupensis (Spruce ex O. Berg) S. A. Mori, Y.-Y. Huang, & Prance.
