fertile extrorse 2-glandular; fourth whorl sterile. Fruit superior, 
naked or surrounded at base by the receptacle, not enclosed in its 
cavity. Trees with persistent leaves. Buds with incomplete scales. 
II. Cryprocaryez.—Flowers usually hermaphrodite. Androceum 
generally similar to that of Cinnamomee, rarely reduced to 3-6 
stamens. Fruit wholly or nearly enclosed in sacciform cavity of 
acerescent receptacle. Trees; leaves and buds as in Cinnamomee. 
III. . Ocorz#.—Flowers usually diclinous, often dicecious (very 
rarely bisexual), with three verticils of fertile stamens ; stamens of 
the third whorl extrorse, 2-glandular sterile stamens of the fourth 
whorl ill-developed sessile, or 0. Fruit superior, naked or surrounded 
at base (but not included) by wholly or partially persistent recep- 
tacle. Trees with alternate, rarely caducous leaves. 
IV. Terranturres.—Flowers usually diclinous dicecious (rarely 
bisexual), in umbelliform inflorescences or glomeruli protected at first 
by an involucre of imbricated bracts or pluriseriate bud-scales. Sta- 
mens of male flowers usually all fertile; valves introrse. Woody 
plants with persistent or caducous leaves. 
V. Cassytuea.—Flowers hermaphrodite or polygamous; receptacle 
very concave, persistent, and becoming fleshy around included fruit. 
Androceum of three whorls of fertile stamens, the innermost introrse 
2-glandular. Leafless parasitic herbs ; stems filiform twining, cling- 
ing by suckers. Flowers spicate or racemose. 
VI. Grrocarpe#.—Flowers polygamous ; receptacle concave per- 
sistent. Fruit inferior induviate. Cotyledons folded or rolled into 
a spiral around the tigellum. Woody plants erect or climbing ; 
leaves digitiveined, entire or lobed. 
VII. Itticurza#.—Flowers usually hermaphrodite ; receptacle 
usually saccate, with a narrow mouth. Androceum isostemonous. 
Fruit induviate by receptacle which possesses vertical wings. Embryo 
fleshy thick non-convolute. Woody climbers with digitate leaves. 
VIII. Hurnanpiza.—Flowers moncecious ; perianth double. 
Male flower isostemonous. Female flower with an inferior ovary 
surrounded by a proper involucre, which is accrescent to form an 
induvium. Flowers united in threes (one female and two male) in a 
common involucre of four imbricated bracts. Trees with simple 
alternate leaves.
