1. X. macronema (stamens long), F. r. M. Fragm. iv. 112 ; Benth. Fl. 

 Austr. vii. 113; Leaves narrow nearly flat or acutely triquetrous, 2 to 3ft. long. 

 Scapes above 1ft. long. Spike 4 to Sin. long, thick and very dense, the flowers 

 much flattened and larger with longer stamens than in any other species. 

 Bracts linear-spathulate, quite glabrous, nearly as long as the outer perianth- 

 segments. Outer segments oblong, shortly acuminate, about 3 lines long, 

 concave, quite glabrous, inner segments fully 5 lines long, with white obovate- 

 spreading laminae. Stamens nearly twice as long'as the perianth ; anthers ovate- 

 oblong.

 1 to 2£t. long and from 1 to nearly 2 lines wide, flat but. thick or more or less 

 triquetrous. Scape when full grown often longer than the leaves, the spike 3 to- 

 Sin. long, 7 to 8 lines diameter when fully out. Spathulate bracts and outer 

 perianth- segments shortly acuminate, about 2 lines long, quite glabrous or 

 minutely ciliate at the end ; inner segments with white . obovate spreading 

 laminae scarcely 1 line broad. Stamens about twice as long as the perianth, 

 very spreading ; anthers ovate-oblong, much smaller than in most species. 

 Capsule acuminate and 7 to 8 lines long in some of the northern specimens, 

 shorter and more obtuse in the southern ones. — Hook. f. Fl. Tasm. ii. 59 ;.
