Helipterum Guilfoylei, n. sp. (Compositae) (named after the 

 Director of the Melbourne Botanical Gardens). 



An annual prostate or ascending, rarely exceeding 4 to 5 cm. in 

 height, covered with long loosely woolly hairs, and with one or 

 more stems branching to form clusters of small ovoid heads. 

 Leaves sessile, narrow, Ihiear, mostly obtusely pointed, and 4 to 

 5 mm. long, channelled on the upper surface, alternate or opposite. 

 Heads partly within the upper leaves, mostly 5 mm. long by 3 

 broad, the outer bracts 2 mm., the inner 4 or 5, and with small 

 yellow or brown laminas, the innermost smaller again without 

 any lamina and very thin. All with various entire margins, and 

 twenty or more in number. Flowers all tubular and hermaphro- 

 dite, usually ten, the corolla, with five blunt points, the style 

 swollen at the base, the pappus about the length of the corolla, 

 of usually 8 plumose scales flattened at their bases and united to 

 form a sessile ring easily separated entire. Achenes 1.5 to 2 mm. 

 long, and quite twice as long as broad, reddish-brown, glabrous, 

 the outer layers becoming mucilaginous in water, but with a 

 reticulate surface before swelling. Style l)ifurcate with papillose 

 ends; it and the stamens barely projecting l)eyoiid the tliroat of 

 the corolla. 



The plant has a close e.\teriial resemblance to H. exiguum, F. 

 V. M., Imt appears to be allied to H. pygmaeum, Benth., and 

 of recently described species. H. verecundum (8. Moore, Journ. 

 Linn. Hoc, vol. xxxiv., 1899, p. 200) is distinguished by its min- 

 ute size, and H. Zacchaeus (S. Moore, Journ. of Bot., 1897, p. 

 166), by its pappus, achenes nearly as broad as long, and green 

 tips to the involucral scales. The latter species also has presum- 

 ably not the mucilaginous seed coat or peculiar style of H. Guil- 

 foylei. Owing to the former fact the whole cluster of ripe 

 achenes adheres and comes out in one mass, usually with the 

 florets and pappus attached, two or three of the florets lieing 

 usually sterile.
