numerous, ^-1 inch long, very narrow linear-spatliulate or linear-obovate, 

 obtuse, gradually narrowed below aud 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 1^—3 inches long, solitary and 

 axillary, usually one or two near the tips of the branchlets, densely covered 

 with a fulvous somewhat glandular tomentum ; bracts 3-4, linear or linear- 

 oblong. Heads f-1 inch in diameter. Involucral scales very numerous, 

 linear, erect, pubescent and glandular. Eay florets rather numerous, not 

 seen fully expanded. Eipe achenia not seen. 



Hab. Eavines on Mount Peel, Nelson, alt. 5,000 feet. 



A curious and remarkable species, distinct from all others, although 

 allied to C. ivalkeri 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 differently shaped leaves. 



2. Senecio pachyphyllus, n. sp. 



A small, robust, densely branched shrub, 3-5 feet high; young branches, 

 leaves, and inflorescence extremely viscid. Leaves 1-1 f 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, •§ inch in diameter, few (6-20), arranged in terminal laxly 

 branched racemes or panicles. Bracts numerous, varying from linear- 

 spathulate to oblong. Peduncles 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. Eay florets yellow, 

 £ inch long, spreading. Pappus hairs white, slender, 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. 



3. Potamogeton cheesemanii, A. Bennett. 

 (" Journal of Botany," March, 1883, p. 66.) 



" 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, 

 5-7 veined, connected with few cross veins, semi-translucent ; upper leaves
