No. 4. 



As explained in No. 1 of these papers, I was unable to take up the 

 Natural Family of Anonaceae in its natural sequence. Having now 

 been able to work it out, I present my account of it to the Society. 

 Another of the Thalamifioral families (Dipterocarpece) still remains to be 

 worked out before beginning the Bisciflorce. In the present paper 

 I have followed, for the most part, the 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 

 so the fact has been noted. 



Order IV. ANONACPJ^. 



Trees or shrubs, often climbing and aromatic. Leaves altei'nate, 

 exstipulate, simple, quite entire. Floivers 2- rarely 1-sexual. Sepals 3, 

 free or connate, usually valvate, rarely imbricate. Petals 6, hypogynous, 

 2-seriate, or the inner absent. {Floivers dimerous in Bisepahtm) . Stamens 

 many, rarely definite, hypogynous, closely packed on the torus, filaments 

 short or ; 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 ; ovules I 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 divaricating. — Distrib. Tropics of 

 the Old World chiefly ; genera about 45 with 500 or 600 species. 



Tribe I. Uvarij;. 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-
