6. Abrotanella filiformis sp. nov. 



Minuta glabra breviter l'epens. 



Folia pauca erecta v. ascendentia 8-12 mm. longa peranguste linearia 

 enervia basi in vaginam striatam expansa. 



Scapi gracillimi solitarii (raro bini) florigeri 5 mm. fructiferi 12 mm. 

 longi ; bracteis 4-5 brevibus peranguste linearibus. 



Capitula solitaria parva 1 mm. longa ac lata ; involueri squamae 8-1 ; 

 flores minuti 5-6, squamas baud excedentes. 



Achenia anguste fusiformia squamis fere aequilonga. 



A minute shortly and loosely creeping glabrous plant giving off at 

 intervals scattered few-leaved flowering-stems. 



Leaves few, very narrow linear, 8-12 mm. long, nerveless, expanded 

 below into a striate sheath. 



Scapes solitary (rarely in twos), very slender, 5 mm. long when in flower, 

 lengthening to 12 mm. in fruit ; bracts 4-5, short, very narrow linear. 



Heads solitary, small, 1 mm. long, and broad ; involucral scales 8-10, 

 shortly oblong, obtuse or sometimes subacute, greenish at the middle, with 

 broad hyaline margins, obscurely 3-nerved ; flowers minute, 5-6, not ex- 

 ceeding the scales. 



Achenes narrow, spindle-shaped, distantly but not deeply ribbed, almost 

 as Ions: as the scales. 



Hob. — Wet peaty puddles in open lowland moor near the head of 

 Paterson Inlet, Stewart Island. 



7. Abrotanella Christenseni sp. nov. 



Folia rosulata 15-18 mm. longa 4 mm. juxta apicem lata anguste 

 cuneata tenuia obtusa apice ac a parte superiore breviter dentata pilis 

 gracillimis ex una cellularum serie constructis + vestita ; costa subtus 

 conspicua. 



Scapi complures maequaliter provenientes erecti simplices sparse pilosi 

 prope basim bibracteati in fructu ad 20 mm. elongati. 



Capitula solitaria parva (1J mm. in diam.) ; flores numerosi minuti 

 involucrum haud excedentes. 



Achenia ad 20 1 mm. longa lineari-oblonga compressa margine + in- 

 crassata. 



Leaves radical, rosulate, 15-18 mm. long, 4 mm. broad, narrow-cuneate, 

 thin, obtuse, shortly toothed at and near the tip, above sparsely clad with 

 rather long slender hairs composed of a single row of cells, under-surface 

 more glabrous except on the evident midrib. 



Scapes several, erect, simple, slender, sparsely pilose, with 2 usually 

 opposite linear bracts near the base, maturing irregularly and in fruit 

 elongating to 15-20 mm. 



Heads solitary, small (1J mm. in diameter); involucral bracts in two 

 series, shortly oblong, obtuse, thin, crenately wavy at the top, the inner 

 narrower ; flowers numerous, minute, not exceeding the involucre. 



Achenes 20 or fewer, 1 mm. long, linear-oblong, compressed, slightly 

 thickened along the margin. 



Hab. — Bare spots in dry fescue tussock steppe, Hanmer Plains. I have 

 great pleasure in dedicating this curious species to its discoverer, Mr. C. 

 Christensen, who is doing valuable work in botanical research in the Amuri 

 district.
