Fruits and Seeds of Annonaceae. Morphology and its Significance for Classification and Identification. 1992.(Bibliotheca Botanica,142). 50 plates. 4 figs. 2 tabs. 101 p.4to. Paper bd.

This paper offers a worldwide survey of the morphology of fruits andseeds of Annonaceae. Of all genera except two a description is given.All descriptions but one are illustrated by line-drawings. Preceedingthe descriptions, a synoptical key based on fruit- and seed charactersis included. In the discussion, the variation of the characters and their distribution among the genera is reviewed. The resulting pheneticgrouping of the genera is compared with the classification on grossmorphological characters by Fries (1959), and with phenetic surveysbased on pollen morphology by Walker (1971 a,b; 1972), and on flowermorphology by van Heusden (in press), respectively. There appear to bediscrepancies between Fries's classification on one side, and thephenetic groupings (including ours) on the other side. In contrast, thethree phenetic groupings support each other to a considerable extent.(Abstract).
