Female inflorescence sessile and solitary in the axils, altogether about 4 cm. in diam- 

 eter. Receptacle at first convex, then ovoid, covered outside with 2 or 3 concentric 

 rows of thick, ovate-lanceolate bracts, 8 to 15 mm. long, the basal ones broader (about 

 8 mm.), the marginal ones rather narrow (1 to 2 mm.), all brownish and squamulose; 

 upper face of receptacle densely covered with erect, stiff bractlets, about 7 mm. 

 long, claviform and attenuate at both ends, longitudinally 

 plicate at the base, minutely hairy or squamulose (lepidote), 

 enlarging later to 10 mm. or more long with an increased thick- 

 ness. Flowers interspersed among the bractlets, 5 or 6 of the 

 latter forming a kind of pseudoperianth around each style. 

 Ovary deeply immersed in the receptacle, ovoid, the ovule 

 hanging from the top of the cell; style 6 to 8 mm. long, the 

 lower part (2 to 4 mm. long) filiform, glabrous, inclosed in 

 the receptacle, the upper part, also glabrous, gradually thick- 

 ening and then dividing into two diverging stigmas, 4 to 4.5 

 mm. long, thick, arcuate and with a verruculose, revolute 

 stigmatic surface. 



Fructiferous receptacle woody, shaped into an ovoid head; 

 bracta and bractlets enlarged; styles persistent. Nutlets 

 ovoid, about 4 mm. long, with a brown testa.
