 A perennial herb with a very short rhizome crowning 

 the long fleshy roots and producing a close rosette, con- 

 spicuous at the flower-period, of linear somewhat fleshy 

 leaves as much as 2*5 cm. long and 2 mm. broad, acute at 

 the apex and expanding at base into a wide vagina connate 

 with that of the opposite leaf to form a sheath. From the 

 rosette radiate many prostrate short branches (at most 

 about 5 cm. long) which ascend at the point and end in a 

 solitary sessile flower. Stem of the shoots thin about 



1 mm. in diameter, longest internodes about the middle and 

 there about 0'5 cm. long, slightly tinted red. Leaves at 

 base of shoots with an oval lamina about 4 mm. long and 



2 mm. broad somewhat fleshy, obtuse or acute, slightly 

 cartilaginous and obscurely scaberulous at the margin, 

 at the base contracted into a short parallel-sided petiolar 

 portion about 1 mm. long, which expands into a vagina con- 

 nate with that of the opposite leaf to form a membranous 

 (when dry) sheath about 2 mm. long open at the mouth ; 

 leaves at the top of the shoot with a linear-lanceolate 

 lamina about 1'2 cm. long and 3 mm. broad shortly 

 mucronulate, margin thinly cartilaginous and obscurely 

 scaberulous, contracted at base into a petiolar portion 

 about 1'5 mm. long, vaginal sheath of the leaf -pair about 



3 mm. long membranous and open at top. Flower sessile
