Pterigeron cylindriceps, si>- n. (tab. Ixix.). Herha 

 ^recta, pilis glandalosis consjJ^rsa, foliis obovatis vel ohlongis 

 in petiolum hrevem angustatis crenato-dentatis 6-10 mm. 

 longis, involucro ante floritioneni ohlongo-cylindrico circiter 

 20 mm. longo inter folia floralia sessili, hracteis herbaceis 

 acutis sursum purpurascentibus interioribus glabris lanceo- 

 latis 18 mm,, longis, floribus exterioribus fJiformibus 

 numerosis brevissime ligulatis (ligidd vix 1 inm. longd), 

 interioribus circiter 15, pappi sefis barbelhdatis, achaeniis 

 tenuibus pubescentibus. Fifty miles west of Oodnadatta and 

 at Moorilyanna Waterhole. Nearest to P. adscendens, but 

 differs in the longer and cylindrical head, the almost glabrous 

 involucre, and the much more numerous flowers in each head. 

 A similar specimen from Mount Parry is placed in the Tate 

 Herbarium under P. lintroides. 



P. adscendens, Benth. Fifty miles west of Oodnadatta. 

 Dwarf specimens 2-5 cm. high. Minuria leptophylla, DC. 

 F^verard Range and Wantapella Swamp. [A not uncommon 

 flower of a bright-blue colour.] J/, denticidata, Benth. 

 Moorilyanna Native Well. [Found growing at the foot of 

 the granite rocks and boulders.] Podocoma nana, Ewart and 

 White. Glen Ferdinand and Everard Range. The ripe 

 achenes have a beak 5 mm. long; pappus 9 mm. long, con- 

 sisting of about 15 long unequal bristles and an outer row 

 of several short bristles. Recorded also from Mount Lynd- 

 hurst (M. Koch) and Torrens Plain (R. Tate). Professor 

 Ewart kindly confirmed the determination. [A very common 

 plant which varied much in size, no doubt according to the 

 amount of moisture in the locality where it grew. Found on 

 sandy soil, also around claypans.] Bracjiycome ciliaris. Less., 

 var. glandulosa, Benth. Glen Ferdinand. I feel some doubt 

 about this determination, the achenes not being quite ripe. 

 The specimens are perennial, the leaves with narrow, distant 

 teeth, and the involucral bracts very blunt, with scarious, 

 purplish, jagged margins. I have a similar specimen from 

 Miss Staer, gathered near Oodnadatta. Calofis Kempei, 

 F.v. M. Twenty miles west of Lambinna Soakage ; Tietkens' 

 Birthday Creek; also from near Oodnadatta (Miss Staer). 

 Leaves vary from obovate-cuneate to lanceolate. Some of 

 the ripe achenes on one specimen bear a single barbed awn 

 in addition to the inrolled pappus-crown, thus showing a 

 tendency towards C. dentex, R. Br. [Not a common plant; 

 -only observed once or twice during the trip.] Calotis 

 latiuscula, F. v. M. et Tate. Moorilyanna Native Well and 

 50 miles west of Oodnadatta. [Not a common plant ; rarely 

 seen.] C. cymbacantha, F. v. M., var. pumila, Benth. Glen 

 Jferdinand and clay pan between Flat Rock Hole and
