As explained in No. 1 of tlieae papers, I was unable to take np the 
Natural Family of Anonacete in its natural sequence. Having now 
been able to work it out, I present my account of it to the Society. 
Another of the Tkalamijloral families (Dipterocarpeai) still remains to be 
worked out before beginning the I}isciJlorce. In the present paper 
I have followed, for the most part, tlie arrangement of tribes and the 
limitations of genera adopted by Sir J. D. Hooker in his Flora of 
British India ; and in most of the instances where I have not done 
80 the fact has been noted. 
Ordbr IV. ANONACEyE. 
Trees or shrubs, often climbing and aromatic. Leaves alternate, 
exstipulate, simple, quite entire. Flowers 2- rarely 1 -sexual. Sepals 3, 
free or connate, usually valvate, rarely imbricate. Petals 6, hypogynous, 
2-seriate, or the inner absent. {Flowers dimerous in Disepalum). Stamens 
many, rarely definite, hypogynous, closely packed on the torus, filaments 
short or 0 ; anthers adnate cells extrorse or sublateral, connective pro- 
duced into an oblong dilated or truncate head. Ovaries 1 or more, apo- 
carpous, very rarely (Anona) syncarpous with distinct or agglutinated 
stigmas, style short or 0 ; ovules 1 or more. Fruit of 1 or more, sessile 
or stalked, 1- or many-seeded, usually indehiscent carpels. Seeds 
large; testa crustaceous or coriaceous ; albumen dense, ruminate, often 
divided almost to the axis into several series of horizontal plates ; 
embryo small or minute, cotyledons divaiicating. — Disti ih. Tropics of 
the Old World chiefly ; genera about 45 with 500 or 600 species. 
Tribe I. UvARi-B. Petals 2-seriate, one or both 
series imbricate in bud. Stamens many, close- 
packed ; their anther-cells concealed by the 
overlapping connectives. Ovaries indefinite. 
Sepals imbricate ; trees or shrubs. 
Flowers small, globular, scarcely open- 
ing ; often uni-sexual and from the
