Xyris] XIII. xyride^. 71 



bud orange-yellow, linear-oblong, exceeding the 2-armed hairy 

 staminodes. The rather stout root-fibres stain the paper on which 

 they are mounted a pale crimson. 



The new leaves which are shooting out above the closely 

 sheathing bases of last season reach 3^ in. long including the 

 sheath (|^ in.) by barely ^ line broad. Peduncles to 5 in. long by 

 a little over \ line thick, spike 21 to 2i by 1 to 1^ lines. Bracts 

 1§ to 2 by I to 1^ lines ; sepals about 2 lines long by between i 

 and ^ line broad. Anthers f line long in bud. 



Comes perhaps nearest to A", affinis but is distinguished by its 

 smaller size, very rigid habit, crowded regularly distichous shoots, 

 terete scape, and smaller spikes.
