subacutis vix coriaceis sublonge petiolatis ; rhachj. puberulo, pedunculis 

 + pubescentibus. 



Hab. — Low flat rocky bars across the Ngakawau River near its mouth, 

 south-west Nelson. The habitat is but little above sea -level, and is 

 frequently submerged during floods. Collected 25th February, 1913. 



8. Euphrasia diversifolia sp. nov. 



Annua : caules gracillimi atro-rubri 8-10 cm. alti, ramos paucos basim 

 juxta emittentes. Folia parva + sessilia obovata v. obovato-cuneata 

 (raro sublanceolata), glabra obtusa integra v. sub apice bidentata, + 2*5 mm. 

 longa, tenuia, subfloralia majora multo latiora coriacea valde obtusata, 

 marginibus manifeste recurvis. Flores in racemis 2 - 5-5 cm. longis dispositi ; 

 pedunculis gracillimis bracteas duplo v. ter superantibus ; calyce obconico 

 pedunculis -| breviore glabro, segmentis obtusis conspicue inaequalibus ac a 

 marginibus recurvatis ; capsula oblanceolata glabra vix emarginata calycem 

 \ superante. 



Annual : stems very slender, erect or arcuate below, 3-A in. high, deep- 

 brown marked by two faint pubescent lines running down from the base 

 of the petioles, giving off a few filiform branches mostly near the base. 



Leaves small, the lower T V in. long or less, sessile or almost so, obovate 

 or obovate-cuneate (rarely sublanceolate), spreading, entire or with a shallow 

 notch on either side near the tips, thin, distant, more or less recurved at the 

 margins ; the subfloral larger much broader and thicker, mostly appressed, 

 margins obviously recurved. 



Flowers in a raceme 1-2 in. long, solitary or more commonly in opposite 

 pairs, in the axils of the bracts ; peduncles two to three times as long as the 

 bracts (+ fin. long), slender, erect, marked by 2 pubescent lines; calyx 

 obconic, about half as long as the peduncles, glabrous, margins recurved, 

 cut about half-way down into 2 principal segments that are again shortly 

 notched at the top, segments obtuse ; corolla not seen ; capsules one and 

 a half times as long as the calyx, oblanceolate, obtuse, glabrous, the top 

 entire or very shortly and obliquely emarginate. 



Hab.— Wet ground on Mount Hector, Tararua Range ; about 3,500 ft. : 

 B. C. Aston ! 



The present species is allied to E. tricolor Colenso. In the latter the 

 •calyx-segments are often more or less unequal, but never so conspicuously 

 so as in Mr. Aston's plant, which is, moreover, annual, and has quite different 

 leaves. Colenso's E. tricolor appears to me to be a valid species. 



9. Pimelea Poppelwellii sp. nov. 



Frutex subrobustus ramosus glaber ad 15 dcm. altus. Folia conferta 

 imbricata crassa coriacea brevia, late ovata v. elliptico-ovata, 8-10 mm. 

 longa + 6 mm. lata, obtusa v. subacuta, vix appressa glabra, supra ^ con- 

 cava, evenosa carinata, breviter petiolata ; floralia longiora ac latiora 

 tenuiora + venosa plana flavo-viridia. Flores terminales in capitulis 

 8-15-floris aggregati, + 1 cm. longi sessiles pallide rosei dioici v. polygamo- 

 dioici, sericeo-villosi ; antheris vix exsertis ; stylis elongatis gracillimis 

 delicate capitatis. Fructus ignotus. 



A rather robust much-branched erect shrub 5 ft. high or less. 

 Branches moderately stout, leafy towards the tops, glabrous. 

 Leaves very dark green, close-set, overlapping, more or less appressed, 

 thick and coriaceous, broadly ovate or elliptic-ovate, about fin. long and
