366 NOTES FROM THE BOTANIC GARDENS, NO. XL, 



describes the leaves as "narrow-linear with revolute margins," and 

 so they are in all the southern specimens; but in the northern 

 localities the leaves have a tendency to flatten out, though both 

 narrow- and broad-leaved forms may occur together. The flower- 

 heads also vary much in size, colour and number of flowers. 

 White is the predominant colour; the not uncommon pinkish tint 

 is already mentioned by Bentham, but the pale yellowish tint 

 seems to be rare. Small white sterile heads, either empty or 

 with a very few flowers, are of common occurrence in this species. 



Helichrysum Boormanii, sp.nov. 



Atherton, N. Queensland (E. Betche; Aug. '01); Boonoo Boonoo, 

 N.S.W. (J. L. Boorman, Nov. '04). 



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 claw^ed; 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 innermost ones reduced to the 

 long claw, with a lamina hardly 1 line long. 



The New South Wales specimens differ only slightly from the 

 Queensland 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 Xerochlsena. 



We were first inclined to regard the Queensland specimens as 

 a form of H. elatum A. Cunn. (in F. v. Mueller's 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. colli7ium 

 DC.
