Uvaria.l Aizonaceis. ly 



connective prolonged beyond anth.; carp, numerous or few, 

 distinct, very rarely solitary, ovules i to numerous ; ripe carp, 

 often stalked, indehiscent (very rarely follicular), few- or 

 I -seeded ; seeds large, embryo small, in copious ruminated 

 endosperm. 



The genera are difficult of definition, and good flowering and fruiting 

 specimens are required to identify the plants. 



Stam. indefinite (over 30), anther-cells concealed by the connectives. 

 One or both rows of pet. imbricate . . .1. Uvaria. 

 Both rows of pet. valvate. 



Pet. similar, or inner row smaller. 



Inner row of pet. coherent at concave bases. 



Tree ; no hooked peduncles . . 2. Cyathocalyx. 

 Climbing by hooked peduncles . . 3. Artabotrys. 

 All pet. flat or slightly concave. 

 Carp, indehiscent. 

 Ovules 2-6. Seeds 1-3 . . . 4. Unona. 

 Ovules I or 2. Seed solitary . . 5. Polyalthia. 



Carp, dehiscent 6. Anaxagorea. 



Inner row of pet. connivent (not coherent 



at concave bases) . . . .7. Xylopia. 

 Pet. dissimilar, inner row coherent into a cone. 



Carp, generally I -seeded . . .8. Goniothalamus. 



Carp. 2-3-seeded 9. MiTREPHORA. 



Stam. definite (6-30), anther-cells not concealed. 



One or both rows of pet. imbricate . . .10. Bocagea. 

 Both rows of pet. valvate. 



Inner row of pet. much larger. 



Stam. 20-30 II. MiLiusA. 



Stam. 6 12, Orophea. 



Pet. all equal 13. Alphonsea. 



A completely tropical family. Of the 39 Ceylon species by far the 

 greater number (32) inhabit the moist low region, and 23 are confined to 

 it, whilst 6 others extend upwards into the lower montane zone, which has 

 also two species, Afiaxagorea and Bocagea coriacea, restricted to it. 

 None reach the upper montane zone. In the dry region 9 species 

 are found, 5 confined to its bounds, and 4 also found in the moist 

 region. 



A large proportion, no less than 18, of our species are endemic, but 

 we have no endemic genus. These for the most part show Malayan 

 rather than Peninsular- Indian affinities. 



I. UVARIA, L. 



Climbing or straggling shrubs ; fl. solitary or in few-fld. 

 inflor., terminal or leaf-opposed ; sep. usually combined into 

 a cup-shaped calyx ; pet. in 2 rows, i or both rows imbricate, 

 or all connate at base ; stam. indef., cuneate or nearly truncate ; 

 carp, indef ; ov. linear, with numerous ovules in i or 2 rows,
