W. H. Harvey on two New Species of Rhizantheae. 387 



keel, more than half as long (generally f rds) as the anterior, 

 dark purplish-red at the apex, pale below ; the anterior red 

 with yellow margins. Perianth, segments united at base into 

 a cup, the anterior nearly as long as the posterior, limb lanceo- 

 late obtuse, somewhat concave, dark brown-red ; claws yel- 

 low, flat or slightly channeled. Filaments subulate, robust ; 

 anthers distinct ; pollen cubical, with fluted angles. 



Females : Anterior bractea as in the male ; lateral (in 

 anthesis) rather longer than it, boat-shaped, acute, with a 

 sharp ciliate keel, distinct; in fruit very much enlarged, and 

 much longer than the anterior, yellow with red tips. Limb 

 of the perianth subglobose or ellipsoidal, obtusely trifid or tri- 

 crenate, red. Style much exserted, filiform. Ovary oval-ob- 

 long, seated in a white, fleshy, cup-like torus, to whose centre 

 it is attached by the attenuated base, dark red, minutely hispi- 

 dulous, containing a fleshy mass, in the centre of which is a 

 white body, of whose nature I cannot satisfy myself. In some 

 ovaries it is very obscure. Ripe fruit deciduous, with the 

 torus (which surrounds its base very much like the arillus of 

 a seed) resembling the ovary, and but little enlarged, dark 

 vinous red, slightly fleshy, with a thin but hard crustaceous 

 endocarp. Contents, myriads of minute, white, cellular bodies, 

 into which the fleshy mass of the ovary is dissolved.

 XX.).
