are grave differential characters ; besides, the reticulated vena- 

 tion of the leaves of the two species is very dissimilar. 



Order LXVII.— THYMELE/E. 

 Genus 1. Pimelea, Banks and Sol. 



1. P. rugulosa, sp. nov. 



Plant shrubby, prostrate, spreading, forming small com- 

 pact low bushes; main stems rather stout, 1ft. -2ft. long, much 

 branched; branches ascending and erect, 8in.-12in. long, 

 stoutish, straight, sparingly hairy ; hairs greyish, short, ad- 

 pressed in small detached patches between the leaves, but 

 never near their bases ; bark pale reddish-brown. Leaves 

 decussate, not close, about 1 line (sometimes 2) apart, patent, 

 decurved, thickish, glabrous, sub-glaucous-green, minutely and 

 regularly marked with light-grey scurf, sub-papillose on under 

 surface, narrow oblong, obtuse, 2-3 lines long, margined ; 

 margins (and petioles) bright-red ; midrib indistinct ; floral 

 leaves slightly larger and broader; petioles short, stout, 

 glabrous, transversely wrinkled below. Elowers sub-terminal, 

 capitate 3-5 together, sessile, closely compacted, with a thick 

 bunch of erect white hairs at their bases. Perianth hairy, 3i 

 lines long, the lower half of tube rose-coloured turgid and 

 rugulose, the upper portion slender and (with the limb) white ; 

 lobes broadly ovate, obtuse, spreading, recurved, longer than 

 the white portion of the tube, their lateral margins slightly 

 incurved. Stamens rather long, exserted ; style much longer.

 of Waipawa ; 1885-88 : W. G. 



Obs. A species having pretty close affinity with P. pros- 

 trata, Vahl., of which species Hook. f. gives no less than three 

 indigenous varieties ; but this plant possesses characters dif- 

 fering from them all. 



Order XI.— CYPEEACE^. 

 Genus 6. Isolepis, Br. 



1. I. novcB-zealandicB, sp. nov. 



Plant very small, densely tufted, sub-erect, slightly branched 

 at base; roots numerous, short, fine, wiry, red; culms and 

 leaves green above, reddish below. Culms about lin. long, 

 leafy (3-4) below spikelet, semi-terete, channelled on upper 

 surface, tips sub-acute. Leaves a little longer than culms, 

 filiform, linear, much dilated and clasping at bases ; tips very 

 obtuse, drooping ; leaf-sheaths (2 or more) loose, truncate, 

 with a short erect obtuse point. Spikelet solitary, sub-sessile, 

 lateral at or below middle of culm, small, ovate, about 1 line 

 long (rarely 1|-) , few-flowered, elongating after flowering ; and
