1. Olearia Crosby-Smithiana sp. nov. 



Frutex humilis, ramosa, compacta, 4-6 dcm. alta. Folia anguste linearia, 

 4-9 cm. longa, 2 mm. lata, marginibus forte revolutis ; costa media in- 

 feriore valde prominente. 



Paniculae summos ramulos versus dispositae ; capitula parva, pauca, 

 floras paucos gerentia. 



A low compact shrub, 4-6 dcm. high, with numerous short erect or 

 suberect branches, marked by the scars of fallen leaves ; the higher part of 

 the branches alone leafy. 



Leaves crowded, alternate, coriaceous, acute, entire, vemless, narrow- 

 linear, 4-9 cm. long, 2 mm. broad, shortly petioled ; margins strongly 

 revolute ; upper surface with a deep longitudinal groove, more or less lacu- 

 nose ; mider-surface marked by a stout midrib that is fringed by a delicate 

 line of whitish tomentum ; the petiole ending below in a broad thickened 

 callosity, above which the leaves become detached. 



Panicles towards the tops of the branchlets, and springing from a 

 cluster of short acute squamiform leaves having white tomentose margins. 

 Peduncles filiform, + 2 cm. long, divided into 2-3 branches that are again 

 subdivided. 



Heads few, small, of few florets ; involucre turbinate ; scales in 2-3 

 series, dark brown, the lower ovate-lanceolate, the upper linear, glabrous 

 or slightly pubescent at the tips. 



Achenes very narrow, glabrous, 1 mm. long ; pappus very slender, 

 spreading, longer than the achenes. 



^rt6.— The Hump (3,500 ft.), south of Lake Hauroko. 



I am indebted to Mr. J. Crosby Smith, F.L.S., of Invercargill, for a 

 number of fruiting specimens of this most distinct species. The narrow- 

 linear strongly ribbed leaves and the small slender inflorescence are very 

 different from those of any other native species. Its nearest ally is 0. lacu- 

 nosa Hook. f. It was collected long ago at Dusky Sound by Mr. Reischek, 

 who gave Mr. T. F. Cheeseman some pieces not in flower or fruit, and I 

 have seen flowerless specimens from the neighbourhood of Puysegur Light- 

 house. 



2. Aciphylla pinnatifida sp. nov. 



Caulis 15-20 cm. altus, gracilis, sulcatus. Folia 5-8 cm. longa, trifolio- 

 lata, usque ad svimmam vaginam divisa ; segmenta linearia, pinnatisecta ; 

 pinnis linearibus, brevibus, integris, subremotis ; vaginae baud in spinas 

 laterales productae. 



Stem 15-20 cm. high, slender, grooved. 



Leaves numerous, radical, 5-8 cm. long, flaccid, trifoliolate, divided 

 to the top of the sheath ; segments linear, pinnatisect, the middle one
