Species novae in Horto Botanico Sydneyano (II). 85 
These characters seen to be constant, but the general appearance, 
habit, leaves and inflorescence of the specimens are so much like the 
typical A. Gibbonsii, that we do not share Mr. Báuerlen's view, who regards 
it as a new species. 
16. Helichrysum Boormanii Maiden and Betche, l. c., p. 366. 
The Queensland specimens are upright shrubs 3 to 4 feet high, 
without any trace of woolly hairs. Stems and leaves glutinous with 
short glandular hairs, especially dense on the branches. Leaves 
lanceolate, acuminate, sessile, 2 to 3 inches long, the upper leaves 
reduced, but the stems generally leafy to near the large solitary flower- 
head. Involucral bracts all clawed; pure white, narrow and acuminate; 
the outermost ones short and shortly clawed; the intermediate ones 
nearly an inch long, with a narrow claw 2—3 lines long; the inner- 
most ones reduced to the long claw, with a lamina hardly 1 line long. 
N. Queensland: Atherton (E. Betche, Aug. 1900): New South 
Wales Boonoo Boonoo, (J. L. Boorman, Nov. 1904). 
The New South Wales specimens differ only slightly from the Queens- 
land ones. The claws of the outer involucral bracts are woolly-hairy and 
broader and less sharply distinguished from the lamina, and the stalk 
under the flower-heads is woolly-hairy as well as the floral-leaves, thus 
approaching closer to H. elatum of the Section Xerochlaena. 
We were first inclined to regard the Queensland specimens. as a 
form of H. elatum A. Cunn. (in F. v.-Muellers wider sense of this 
species, including H. glutinosum Hook.), but Mr. Boorman’s discovery of 
the same plant, almost unchanged, though found about 12 degrees 
of latitude further south, induced us to describe it as a new species. 
In systematic sequence it should be placed near to H. collinum DC. 
17. Stylidium debile F. v. M. var. paniculatum Maiden et Betche, |. c., 
p. 361. : 
A very weak slender plant sometimes nearly 1 foot high, with a 
paniculate inflorescence, the lower paniele-branches often above 1 inch 
long. Leaves and flowers like the type, but the calyx lobes longer and 
narrower, and the capsules shorter and broader. Specimens collected at 
Wardell, Richmond River (E. Betche, Aug. 1884), and Wallangarra (J. L. 
Boorman, Nov. 1904) are intermediate forms between the typical S. debile 
and this variety. 
New South Wales: Boonoo Boonoo, near Tenterfield (J. L. Boor- 
man, Feb. 1905). 
18. Prostanthera granitica Maiden et Betche, 1. c., p. 369. 
A compact, bushy shrub, about 3 feet high, somewhat of the habit of 
Westringia rosmarinifolia, covered all over with white hairs, long and dense 
on the young shoots, on the calyces and on the under side of the leaves, 
short and scanty on the upper side of the leaves and on the old branches. 
Leaves very shortly petiolate or almost sessile, ovate-lanceolate, with 
occasionally a slightly cordate base, 3 to 5 lines long, the margins 
recurved or revolute, leaving frequently the under side exposed only on
