CONSPECTUS OF THE SECTIONS OF THE GENUS 



same receptacles as the gall flowers : fertile female flowers alone in another set of receptacles : 

 perianth of fertile females usually gamophyllous, 4 or 5-cleft (of separate pieces in gibbosa 

 and Decaisneana) ; small trees, erect or sub-scandent shrubs. 



II. 



Urostigma- 



Male, fertile female, and gall flowers in the same receptacle ; stamen 1 ; 



(stamens 2 in callosa and vasculosa) ; stigma elongate, usually acute ; receptacles in the axils of 

 the leaves or of the scars of fallen leaves, tribracteate at the base (except in Kurzii, nervosa 

 and pubinervis ) ; leaves alternate, entire, coriaceous or sub-coriaceous, rarely membranous ; 

 usually trees or powerful climbers ; epiphytal at least in early life. 



III. 



Syncecia. 



Flowers unisexual or neuter: male flowers with 1 stamen : male and gall 



flowers in one set of receptacles, fertile female and neuter flowers in another set (neuters absent 



in 



apiocarpa) ; climbers with large coloured receptacles, the leaves tesselate beneath. 



IV. 



Sycidium. — Flowers unisexual : male and gall flowers in one set of receptacles ; 

 fertile female flowers in a distinct set of receptacles; male flowers with 1 stamen (stamens 

 sometimes 2 in copiosa and cuspidata). Leaves alternate ; receptacles small, axillary, more 

 or less scabrid (a few have receptacles in fascicles from the stem) ; shrubs, small trees or 

 climbers ; rarely epiphytal. 



V. 



CoveUia*— Flowers unisexual; male flowers in the same receptacles as the gall flowers, 



monandrous, the perianth of 3 or 4 distinct pieces : female flowers in separate receptacles 

 from the males and galls, pedunculate or sessile, the perianth gamophyllous, much shorter 

 than the ovary, or wanting (rarely consisting of 4 or 5 pieces) ; the receptacles on long sub- 

 aphyllous branches issuing from near the base of the stem, often sub-hypogseal ; or on shortened 



branchlets 



(tubercles) from the stem and larger branches ; or axillary : shrubs or trees, never 



epiphytes or climbers.
