-cottony on under- surface, their lateral margins incurved, often 

 twisted. Scape single, fin.-lin. long, slender, almost seta- 

 ceous, finely cottony, with 1-2 narrow acuminate cauline 

 bracts. Head 2^ lines diameter. Involucral scales about 10, 

 spreading, sub-ovate-lanceolate acuminate, the inner series 

 narrower linear acuminate, thin, light-brown (old), scarious, 

 -glabrous. Keceptacle sub-papillose. Pappus sub 20, rather 

 long for plant, white, spreading, flexuous, 2-nerved, scabrid 

 below, upper portion smooth, flattish, tip obtuse. Achene 

 Tj^^in. long, terete, slightly tuberculate ; tubercles linear, 

 patent. 



Hab. In boggy ground, near eastern l)ase of Mount Tonga- 

 riro, County of East Taupo ; 1889 : il/r. H. Hill. 



Obs. This is a remarkable little tiny plant, yet, though 

 very minute, attracting attention at first siglit from its pure- 

 white hair-like leaves, when closely incurved, contrasting so 

 strongly on the black soil. Its pappus, on examination, re- 

 veals the most curious structure (as described), which is also 

 constant, and (to me) unique. Although I have received 

 several whole plants (in a little mass), yet only one possessed 

 a floral head, and that old and imperfect, containing only its 

 involucral scales with oie seed ! It may piove to be a species 

 of Senecio, or of some other allied genus ; yet, for the sake of 

 its peculiar pappus, also of its filiform hair-like leaves, I have 

 ventured to describe it. 



Order XLI. Campanulace.e. 



(Including Goodeniacece.) 

 Genus 5. Selliera, Cavanilles. 



1. S. mlcrophylla, sp. nov. 



Plant very small, creeping, twiggy; mam stems hypo- 

 gffious, a few inches long, nnich branched, spreading, implexed, 

 slender, woody, wiry, very flexuous, rooting at nodes, red- 

 dish-brown ; branchlets very short, sub |-in. long, yellowish, 

 their tips only appearing above soil, procumbent, matted. 

 Leaves few, small, much scattered, sometimes 3-4 at nodes, 

 spreading, broadly lanceolate or sub-obovate-lanceolate, about 

 1 line long (some much smaller), thickish, entire, glabrous ; 

 petioles long flexuous, twice the length of leaf. Peduncle 

 terminal solitary, 1-flowered, 1 line long; bracteoles small. 

 Calyx-lobes rather large for plant, long, sub-acute, appressed, 

 thickish, glabrous, shining. Corolla 2 lines long, glabrous, 

 dull-purple, lobes 5 (sometimes 6), rather large, sub-acute, 

 spreading, with dark veins regularly reticulated. Stamens 5 ; 

 anthers elliptic, pale-yellow. Style longer than stamens, 

 very stout, dark-brown, with dilated orbicular cup-like indvi-
