| This paper follows upon an earlier paper in the series “Studies in Annonaceae” (Maas et al. 1986). Twelve new species are described, viz. 2 in Duguetia, 1 in Ephedranthus, 5 in Guatteria, 2 in Hornschuchia, 1 in Tetrameranthus, and 1 in Unonopsis. A new combination is made in Enicosanthellum. Some amendments and additions to the revision of Tetrameranthus (Westra 1985), including an updated key, are given. Monocarpia euneura Miq. appears to have priority over M. marginalis (R. Scheffer) James Sincl. Additional collections have been made of the rare species Bocagea longepedunculata Martius, Xylopia crinita R.E. Fries, and Xylopia excellens R.E. Fries. Attention is drawn to several recent collections from Bahia, Brazil, which are perhaps referable to... |

| Several species in neotropical genera are described, viz. 1 in Bocageopsis, 2 in Cremastosperma, 1 in Hornschuchia, 1 in Oxandra, 4 in Pseudoxandra, and 2 in Unonopsis. Cremastosperma anomalum R.E. Fries is transferred to Malmea. Cremastosperma pacificum R.E. Fries is recorded for Panama for the first time. Xylopia ulei Diels, X. neglecta (O. Kuntze) R.E. Fries, and X. intermedia R.E. Fries are brought into synonymy with X. benthamii R.E. Fries, X. parviflora Spruce, and X. sericea A. St.Hil. respectively. The African Xylopia parviflora (A. Rich.) Benth., non Spruce, now has to bear the name X. longipetala De Wild, et T. Durand. |

| SETTEN, A. K. van & KOEK-NOORMAN, J.: Studies in Annonaceae. VI. A leafanatomical survey of genera of Annonaceae in the Neotropics. — Bot. Jahrb. Syst. 108: 17—50. 1986. — ISSN 0006-8152. Within the scope of the multidisciplinary research project on systematics of Annonaceae, a survey of the leafanatomical features and their distribution in the neotropical Annonaceae is presented. The studied specimens form a rather homogeneous group, as may appear from the family description given here. A detailed study of the leafanatomical features reveals, that differences are mainly found in the indument, the position and contents of the idioblasts, the structure of the primary vein, the type of crystals in the epidermal cells, and the type of sclereids. Based on... |
