is found there ; a curious kind of gall-like excrescence, the work, 

 doubtless, of some insect. A very similar one is also to be met 

 with at the tips of the brauchlets of Hydrocotyle concinna, Col., 

 mentioned bv me in my description of that plant. ("Trans. 

 N.Z. Inst.," vol. xvii., p. 239.) 



2. C. heterophylla, sp. no v. 



Plant a small, slender, erect shrub 4-5 feet high, of irregular 

 and diffuse growth ; bark pale-greyish-brown. Branches long, 

 loose, and very slender, thickly pubescent (as are also branchlets, 

 stipules, and petioles,) with short white hairs ; branchlets oppo- 

 site, long, almost filiform, arcuate, few-leaved. Leaves few, 

 scattered, usually in pairs about 1 inch apart, membranaceous, 

 glabrous, light-green above, paler below, spreading, of various 

 shapes and sizes — rhomboidal, sub-orbicular, lanceolate, and 

 narrowly linear, 3-4 lines long, ^ - 3 lines broad, tips acute, 

 veins red and reticulated, margined ; margins red and a little 

 recurved, entire and slightly sinuate-crenulate, gradually nar- 

 rowed into the petiole ; petiole short, slender, under 1 line long ; 

 stipules very short but broad with a point, sub-ciliated. Drupe 

 lateral, solitary on a short peduncle, generally on the under side 

 of branches opposite to leaves on the upper, and at the outer 

 angles of branchlets, globose, 2 lines diameter, purple-black, 

 glossy, juicy, sweet ; calycine lobes at base of drupe persistent, 

 small, aeltoid, pubescent, spreading. Nuts very small, elliptic, 

 1 line long, gibbous, very flat on their sides of junction. 



Hab. In thick, dry woods near Norsewood, County of Wai- 

 pawa ; 1885 : W.V. 



Obs. A species having affinity with C. rhamnoides and C. 

 divaricate, A. Cunn., also with 0. concinna. Col.,* but very 

 distinct. It is a curious and striking plant in its foliage, from 

 their extreme diversity ; all the shapes mentioned above being 

 often found on one branchlet. Its long, drooping branches are 

 by far the most slender of all the species of the genus known to 

 me ; their being also so very bare of leaves helps to show their 

 extreme tenuity. Flowers not seen ; fruit plenty. 



Order XXXIX. COMPOSITE. 

 Genus 1. Olearia, Mcench. 



1. 0. snborbiculata, sp. nov. 



Leaves sub-coriaceous, alternate, about £ inch apart, broadly 

 elliptic, 1^-2 J inches long, obtuse and sub-acute, base rounded 

 and regular, margin entire in the lower half, slightly sinuate in 

 the upper, with a few very small (scarcely developed) blunt 

 teeth, glabrous, green and shining on the upper surface (but
