involute. Stamens spreading, nearly twice as long as the perianth, filaments 

 broad ; anther oblong. Style erect, thick, about as long as the perianth ; stigma 

 minute. Capsule protruding, but not matured on the specimen examined. • 



Hab.: Port Curtis, John Wheatlroft, M.A. 



The clisoovery again p£ this plant is of interest on account o£ its not having been met with, so 

 far as I am aware, since it was first found by Dr. Robert Brown in about 1802 near about the 

 same locality. 



4. X. hastilis (flower spike pike-like), R. Br. Prod. 288 ; Benth. Fl. Austr. 

 vii. 115. " Tchuckah," Bundaberg, Keys. " Goona-ngulla," Mackay, Macartney. 

 ■Caudex very short or often scarcely prominent. Leaves 8 to 4ft. long, 2 to 3 

 lines broad, flat in front, but with the dorsal angle more or less prominent. 

 Scape usually 3 to 4ft. long below the spike, which attains from 1| to 2ft. but is 

 not so thick as that of A', arborea, and readily known by the dense rusty tomen- 

 tum covering the ends of the bracts and outer perianth-segments, especially 

 conspicuous before the flowers expand. Bracts linear-spathulate, mostly very 

 narrow. Outer perianth-segments about 2 lines long, oblong, 3 or 5-nerved, 

 opaque, concave, scarcely acuminate, pubescent outside ; inner ones very little 

 longer ; dilated hyaline and somewhat spreading at the end. Filaments only 

 shortly exceeding the perianth. Full-grown fruiting spikes under lin. diameter 

 without the capsules, which are about fin. long, obtuse, protruding from the 

 spike.— F. v. M. Fragm. iv. 113 ; Bot. Mag. t. 4722. 



Hab.: A swamp species in southern localities, extending to Mackay. 



Analysis of resin : Eesin soluble in alcohol 82 %, Benzoic acid, 9'4 %. — Laiiterer. 



5. X. arborea (tree-like), R. Br. Prod. 288; Benth. Fl. Attstr. vii. 

 115. " Dackowar," Taromeo, Shirley. Caudex growing out to several feet in 

 height with a diameter of 6 to 9in. Leaves as in X. hastilis, flat or triquetrous, 

 •3 to 4ffc. long, and 2 to 3 lines broad. Scape under the spike attaining 5 or 6ft. 

 -and the spike itself 3 to 4ft. long, 1 to If in. in diameter when full grown without 

 the capsules. Bracts linear-spathulate, nearly as long as the perianth, quite 

 glabrous or slightly ciliate at the tips. Perianth- segments about 3 lines long, 

 -3-nerved, the outer ones concave at the end with a very short obtuse point, either 

 quite glabrous or shortly and sparingly pubescent ; inner ones scarcely longer, 

 the dilated ends hyaline and slightly spreading. Stamens not much longer than 

 the perianth. Capsule 7 to 8 lines long, more acuminate than in A', hastilis. 



The common large species in southern localities. 



Analysis of resin: Eesin soluble in alcohol, 93'5 %, Benzoic acid, 5 6 %. — Lauterer. 



The resin if given as a powder of 1 drachme or more, stops diarrhoea. Is also an excellent 

 antiseptic for wounds and ulcers; also recommended for external application on chronic ulcers.: 

 ■ — Lauterer. 



6. X. bracteata (bracts prominent), K. Br. Prod. 288 ; Benth. Fl. A ustr. 

 vii. 116. Caudex very short. Leaves about 2ft. long, 1 to 1| line broad, 

 concave on the upper side, the dorsal angle slightly projecting in the lower 

 part, tapering upwards into a narrow triquetrous point. Scape 2 to 3ft. 

 high, the spike usually 4 to 6in. long and little more than fin. diameter, but in 

 some larger specimens twice that length and fin. diameter. Subtending bracts 

 subululate and very conspicuous in the young spike, but most of them fallen 

 away at the time of flowering or concealed by the outgrowing perianths. Bracts 

 or bracteoles surrounding the flowers linear or linear-spathulate, distinctly 

 acuminate, glabrous or with a tuft of a few hairs on their apex, all shorter than 

 the perianth. Outer perianth-segments oblong, almost hoodshaped and acuminate 

 at the top, scarcely 2| lines long; inner segments rather longer, their dilated 

 hyaline ends slightly spreading but much less conspicuous than in X minor. 

 Fruit small. 



Hab.: Mr. Bentham considered that some specimens in Baron Mueller's Herbarium which 

 were obtained from near Sjringsure might belong to this species.
