B. Rhizanthece. Root-parasites without chlorophyll or foliage-leaves, generally 

 with stunted vegetative organs and very large solitary flowers or small flowers on 

 a dense inflorescence (i) ; whorls dimerous to octamerous (i), trimerous (2), or 

 pentamerous and decamerous (3); ovary with one or eight (i) loculi ; the placentae 

 and anthers of very peculiar form ; a very great number of small seeds with rudi- 

 mentary embryo. 



Families: i. Cytinese, 



2. Hydnoreae, 



3. Rafflesiaceae, 



III. Aphanocycl^. 



Flowers hemicyclic or cyclic, or the parts arranged spirally ; the members of each 

 whorl usually free, not coherent with one another, or only in the gynapceum ; perianth 

 generally distinctly separated into calyx and corolla ; the numbers of the parts in the 

 four whorls very variable ; stamens usually more in number than perianth-leaves ; carpels 

 forming generally one, several, or a large number of monocarpellary ovaries ; in G the 

 ovary is superior and bi- or quadri-locular. Ovules springing occasionally in all the 

 sections from the inner surface of the carpels. 



A. Hydropeltiditiecp. Water-plants with solitary lateral and usually large flowers, 

 the perianth-leaves and stamens variable in number and arranged spirally ; ovaries 

 several and monocarpellary (i, 2), or one only polycarpellary and multilocular ; 

 embryo small, surrounded by a small endosperm in a hollow of the perisperm. 



Families; i. Nelumbiaceae, 



2. Cabombeae, 



3. Nymphaeaceae. 



B. Polycarpee. Parts of the flowers arranged spirally or in whorls, when in 

 whorls usually dimerous or trimerous, each organ generally consisting of more than 

 one whorl, rarely in four pentamerous whorls (2); gynasceum consisting of one, 

 several, or a larger number of monocarpellary ovaries, which are one- or many- 

 seeded ; embryo small ; endosperm none (8), abundant, or very large (9).

C. Crucljiorcp. Perianth-whorls dimerous; in (3) and (4) corolla of four petals 

 placed diagonally ; staminal whorls two or more, each consisting of two stamens or
