502 NOTES ON XYRIS. 
7. X. suncea R. Br. Prodr. 256. ; 
’ ‘This species, placed by Bentham under X. gracilis (l.c. 79), 18, 
I think, quite distinct. The habit is by no means ‘“ gracilis,” the 
plants being of a shorter sturdy growth, 15-25 cm. in height, or 
less than half that of X. gracilis, with leaves of only 5-10 cm. 
length. The spikes are broader and rounder, with concolorous 
chestnut-brown bracts carinulate above the middle. The lateral 
sepals are also shorter, with a well-marked scabridulous keel.

ar. tenuior R. Br. MS. Leaves and peduncles slenderer than 
in the type, the former 8-20 cm. long, -25—-7 mm. broad, the latter 
‘5-35 em. long by -5 mm. or less in diameter; spikes smaller, but 
otherwise similar, 8-5 mm. long and broad.

regular five-rowed arrangement of the bracts. Thus the spikes in 
Labillardiere’s type are ellipsoid-lanceolate, 8 by 8 mm., and com- 
prise three rows of barren scales followed by three perfect flowers ; 
those in Brown’s plant are broadly ellipsoid from a turbinate base, 
may have as many as seven rows of barren scales, increasing very 
size, and greater or less regularity of the five rows of bracts. The 
specimens, that is to say, bear out Brown's view. Kunth, in his
