or subspii'ally marked. Outside of each wedge is a bundle of liber-cells, wbicb are 

 long sclerogen-tubes. This arrangement accords with that of Selosis, and is essentially 



exogenous. 



The young peduncle and capituliim are wholly concealed by the imbricating scales and 

 bracts, which are hexastichously arranged in my specimens, but pentastichously as 

 described by Swartz. As the peduncle elongates the bracts fall away from the lower 

 part of the capitulum, leaving an areolated surface ; the uppermost are persistent for a 

 considerable period. The upper part of the peduncle or base of the capitulum is rough 

 with conical papiUse, which become fusiform and slenderer upwards as they mix with the 

 articulated threads and female flowers, of which they appear to be arrested states. 



The female flowers protrude their styles, wliich are bent down under the bracts, as 

 soon as the latter faU away, and the evolution of the flowers follows the same law as in 

 Selosis. The ovary resembles that of Scybaliuni more than of Selosis, being broader, with 

 larger semicircular lips to the calyx and short stout diverging styles. The fruit is broadly 

 ovoid, tnmcate at both ends, striate, sulcate towards the apex, and more tui'gid than usual 

 amongst the Selosiclece. On a transverse section the style is found to consist of about 

 eight large cells surrounding a few smaller ones that enclose a soft conducting tissue. 

 The seed is broadly oblong, compressed, very oily, of the same structure as Selosis. 



The articiUated threads of the capitulum are (like the ovaries) much broader in this 

 genus than in its allies, and are often fusiform and geminate. The apical cells turn black, 

 and their cell-walls become minutely wrinkled soon after the bracts fall away. 



The male flowers have often a 4-lobed perianth, and the odd lobe is as often the lower 

 as the upper ; there being no constant arrangement of the lobes with reference to the 

 axis of the capitulum. The anthers are 2-celled, narrow oblong, and the pollen escapes 

 through an u-regular opening at the apices of the loculi : the filaments are free just below 

 the insertion of the anthers. PoUen globose, with four minute papDlse on the surface.
