Gnaphaliwm. |] COMPOSITH. 327 
10. G. collinum, Lab. Pl. Nov. Holl. ii. 44, t. 189.--A tufted 
perennial herb 3-12in. high, usually with creeping and rooting 
stolons and slender erect cottony stems. Leaves mostly radical, 
very variable in size, 4-3 in. long, lanceolate-spathulate or oblong- 
spathulate, acute or obtuse, petiolate, white and cottony on both 
surfaces or glabrate above; cauline leaves much smaller and nar- 
rower, linear - spathulate, sessile. Heads small, compacted into 
dense clusters or compound heads similar to those of G. japonicum, 
but smaller and not so compact, and with fewer smaller subtending 
floral leaves. Involucres broader than in G. japonicum; bracts 
linear-oblong, obtuse, scarious and hyaline. Florets and achenes 
as in G. japonicum.—Hook. f. Fl. Nov. Zel. i. 189; Handb. N.Z. 
Fl. 155; Benth. Fl. Austral. ii. 654; Kirk, Students’ Fl. 300. 
G. simplex, A. Rich. Fl. Nouv. Zel. 237; A. Cunn. Precur. n. 451. 
Var. obscurum, Kirk, Students’ Fl. 300.—Forming grey matted patches 
seldom more than lin. high. Leaves 4-3 in., linear, glabrate above, grey with 
appressed tomentum beneath. Scape leafy or almost wanting. Heads in 
terminal fascicles of 2-4 or solitary. Involucral bracts 3-10, linear, obtuse. 
Var. monocephalum, Kirk, 1.c.—Very small. Leaves all radical, 4in. 
long, linear, obtuse or acute. Head solitary, sessile or on a slender filiform 
scape 3-1 in. high. 
KERMADEC IsLANDS, NorTtTH AND SoutTH Ispanps, SteEwarr ISLAND, 
CHATHAM JsnANDS: Plentiful from sea-level to 4500 ft. November—March. 
The two varieties not uncommon on the mountains of the South Island. 
Luxuriant forms of this are best distinguished from G. japonicum by being 
perennial, by the creeping stolons, smaller glomerules with fewer floral leaves, 
and by the broader inyolucres. It is also a native of Australia and Tasmania. 
10. RAOULTA, Hook. f. 
Perennial herbs, usually of small size, either densely tufted and 
compacted or creeping and matted. Leaves small, alternate, entire, 
often closely imbricated. Heads small, solitary, terminal, sessile or 
nearly so, heterogamous and discoid. Involucre oblong, campanu- 
late or hemispherical ; bracts imbricated in 2-3 series, the inner ones 
often with white radiating tips. Receptacle narrow, flat or convex, 
naked. Florets of the circumference in 1 or 2 rows, female, 
filiform, 2—3-toothed. Disc-florets hermaphrodite, tubular with a 
funnel-shaped 5-toothed mouth. Anthers sagittate at the base, 
produced into fine tails. Style-branches nearly terete, truncate or 
subeapitate. Achenes oblong. Pappus-hairs in one or several 
series, slender or thickened at the tip. 
A genus founded more upon habit than upon really good and distinctive 
characters. It may be said to be intermediate between the Hugnaphaliee and 
Helichrysee, the female and disc florets being often nearly equal in number. It 
is easily divided into two sections by the remarkable differences between the 
pappus-hairs, which may ultimately, when the Gnaphalioid Composite are 
thoroughly worked out, be found sufficient to constitute separate genera. Several 
of the species are difficult of discrimination, and require further examination,
