Genus 17. Senecio, Linn. 

 1. S. tripetaloides, sp. nov. 



A small, neat, upright shrub, 2|-ft.-3ft. high, bushy 

 above, main stem l^in. diameter; bark grey. Branchlets — 

 peduncles and involucres — greenish, very slightly scurfy and 

 glutinous. Leaves alternate, rather distant and" conlined to 

 ends of branchlets, petiolate, broadly lanceolate or narrow- 

 oblong, obtuse, slightly tapering, l-|-in.-2in. long, 9-11 lines 

 broad (some smaller), coarsely and irregularly serrate, mem- 

 branaceous, glabrous, light-green, paler below with scanty 

 line white scurf ; veins white, largely anastomosing on upper 

 surface ; petioles ^ in. long, subterete, canaliculate, stoutish, 

 pale-green. Flowers rather numerous, terminal, subcorym- 

 bose, loose, on long axillary slender peduncles 1 in. -2 in. 

 long, each usually containing 5 (rarely 4-6) heads of florets 

 on long slender pedicels ^in.-lin. long, each having a leaf- 

 like bract at base and a small linear appressed bracteole 

 (sometimes 2-3) at base of involucre. Heads small, h in. 

 diameter, bright-yellow. Involucre erect, cylindrical, 3 lines 

 long ; scales 5, linear-oblong, 3-nerved, margins membranous, 

 broad ; tips obtuse, ciliolate. Eay-florets 3, spreading, equi- 

 distant ; ligulee broadly elliptic, Jin. long, tip obtuse, slightly 

 3-notched, smooth, subconcave, obsoletely many - nerved ; 

 style short, one-third length of ray, slender, curved, ob- 

 tuse. Disk-florets 5, 5-lobed ; lobes 3-ribbed, largely revolute ;

 from Povertv Bay ; also (earlier) north of East Cape : Mr. H. 

 Hill. 



Obs. I. The affinities of this plant are with S. glastifolius, 

 Hook., though very distinct. The heads present a peculiar 

 appearance from each having only three spreading divergent 

 ray ligulge. 



II. The description is taken from living specimens in Mr. 

 Hill's garden, Napier, flowering November, 1897.

 succulent, dark-reddish, forked; 2 branches, one 3 in. and one 

 2 in. long, stout, each having 2 branchlets of 2 in. -3 in. in
