numerous, 3-1 inch long, very narrow linear-spathulate or linear-obovate, 
obtuse, gradually narrowed below and then suddenly expanded into broad 
membranous sheathing bases, hoary or silky above, beneath covered with 
soft white tomentum, suberect when young, patent or deflexed when old; 
margins strongly revolute. Peduncles 11-8 inches long, solitary and 
axillary, usually one or two near the tips of the branchlets, densely covered 
with a fulvous somewhat glandular tomentum ; bracts 8-4, linear or linear- 
oblong. Heads 3-1 inch in diameter. Involucral scales very numerous, 
linear, erect, pubescent and glandular. Ray florets rather numerous, not 
seen fully expanded. Ripe achenia not seen. 
Hab. Ravines on Mount Peel, Nelson, alt. 5,000 feet. 
A curious and remarkable species, distinct from all others, although 
allied to C. walkeri and C. ramulosa. From the former it is distinguished 
by its smaller size, smaller, narrower, and more woolly leaves with revolute 
margins, and by the smaller flower-heads. It is at once separated from 
the latter by its larger size, more copiously branched habit, and by the 
much larger and very gra shaped leaves. 
- Senecio pachyphyllus, n. sp. 
A small, robust, Mal branched shrub, 8-5 feet high; young branches, 
leaves, and inflorescence extremely viscid. Leaves 1-12 inch long, shortly 
petioled, oblong or oblong-obovate, entire, obtuse, extremely thick and coria- 
ceous, glabrous above, below covered, except the midrib, with dense white 
or pale buff closely appressed tomentum ; margins revolute. Flower-heads 
rather broad, 2 inch in diameter, few (6-20), arranged in terminal laxly 
branched racemes or panicles. Bracts numerous, varying from linear- 
spathulate to oblong. Peduneles slender, nearly glabrous, but excessively 
viscid. Scales of the involucre few, obtuse, rather membranous, nearly 
glabrous, but with a tuft of woolly hairs at the apex. Ray florets-yellow, 
.X inch long, spreading. Pappus hairs white, eee scabrid. Achenes 
glabrate. 
Hab. Mount Arthur and Mount Peel, Nelson, not uncommon from 
3,500 to 5,500 feet alt., T.F.C. 
Allied to S. robustus, Buchanan, but distinguished by its very viscid and 
coriaceous leaves, narrow few-flowered racemes or panicles, and nearly 
glabrous peduncles and scales of the involucre.

** Stem simple (?) " (branched, T.F.C.), ‘striated, internodes strongly 
marked by an irregular annulus. Lower leaves alternate, strap-shaped, 
gradually attenuated into the petiole, less so at the apex, not denticulate,
