20 lY. ANONACE^. 



Order IV. ANONACE^. 



Sepals usually 3, distinct, or more or less united in a 3-lobed or 3-toothed 

 calyx (in Eupomatia united in one mass with the petals). Petals usually 6, hypo- 

 gynous, in two rows, 3 outer ones alternating with the sepals, 8 inner ones alter- 

 nating with the outer, sometimes all united in a ring at the base, those of each 

 row valvate or imbricate in the bud. Stamens indefinite, usually very numerous, 

 closely packed on the thickened torus, roiind or under the carpels, linear or wedge- 

 . shaped, with 2 adnate anther-cells on the back or edges, often concealed by the 

 more or less dilated summit of the connectivum. Gynoecium of several, often 

 very many carpels, distinct (except in Eupomatia), closely packed on the centre of 

 the torus, terminating each in a capitate stigma, or in a thick oblong or rarely 

 more slender style, stigmatic on the top or inner side. Ovules in each carpel 

 either 1 or 2, ascending from the base, or two or more attached to the inner angle 

 of the cavity, anatropous. Fruit either of several distinct carpels, sessile or 

 stalked, indehiscent and fleshy or pulpy, sometimes opening along the inner edge, 

 or the carpels more or less united in a single mass. Seeds with or without an 

 arillus. Albumen copious, always ruminate. Embryo very small, near the 

 hilum. — Trees, shrubs or woody climbers. Leaves alternate, simple, and quite 

 entire, without stipules. Flowers sessile, or on 1-flowered pedicels, solitary, or 

 few together, terminal, lateral, or axillary, usually of a greenish-yellow or purple 

 colour.
