Diplachne loliiformis, F. v. M. Glen Ferdinand. Stunted 

 specimens under 10 cm. high. Fajjpo'phorum nigricans, R. Br. 

 Moorilyanna Native Well : Musgrave Ranges and 10 miles 

 east thereof. [A common grass, west of Wantapella Swamp; 

 stock seem to like this grass when it is young.] P. avenacetiin, 

 Lindl. Wantapella Swamp. [Not a common grass; only 

 found in this one locality.] AntJiistiria ciliata, L. "Kangaroa 

 Grass." Musgrave and Everard Ranges. [No doubt 

 owing to the long drought, this grass was very stunted ; in 

 places and where the rain had fallen it was 2 to 3 feet high ; 

 sometimes found on very stony ground.] Aristida arenaria,. 

 Gaud. Moorilyanna Native Well. 



Triodia aristata, sp. n. (tab. Ixx.). Gramen caespitostnn 

 fllnhrum rigid um, foliorum lamina involutd pungente^ 

 vagina subturgidd striata, liguld in circtdo hrevissinio pilorum 

 conversd, panicidd angustd, glumis vacuis 12-13 mm. longis- 

 carinatis 3-o-nerviis longe acuminatis, spiculis compressis- 

 d-6-floris, glumd fioriferd 9 mm. longd hifldd et inter lohos 

 acutos aristam 2-3 mm. longam gerente deorsum 9-nervid, 

 nervis ternatim congregatis villosis. "Porcupine Grass." 

 Nearest to T. irrifans, R. Br., but differs in the longer, almost 

 awned outer glumes and in the acute lobes of the flowering 

 glume with the midnerve excurrent in an awn which is twice 

 as long as the lobes. An exactly similar specimen is in the 

 Tate Herbarium, placed under Schedonorus littoralis, Beauv., 

 to which it bears considerable resemblance, especially as this 

 Triodia, at least when dried, is straw-coloured. Tate's speci- 

 men is unlabelled, but a loose label in the folio is marked 

 "Mt. Aroona, 30/8/83." This place is near the eastern shore 

 of Lake Torrens, and very probably the specimen was gathered 

 there. [Grew in very large bushes on the sandy flats between 

 the ranges.] 



Eragrostis eriopoda, Benth. Everard Range and sur- 

 rounding country. [A very common grass all over the granite 

 country; too hard and wiry to be of much good.] E. falcata. 

 Gaud. Forty miles west of Oodnadatta. A starved specimen 

 with panicle only 15 mm. long. E. chaetophylla, Steud. 

 Tietkens' Birthday Creek. [Seems to be a common grass in 

 the Musgrave Ranges.] E. Brownii, Nees. Wantapella 

 Swamp. Spikelets 10-25 mm. long, flowers 20 to over 50. 

 [This pretty little grass was seen growing on the hard soil near 

 claypans.] E. pilosa, Beauv. Flat Rock Hole and Mooril- 

 yanna Well. [Only saw this plant growing in one locality on 

 a large claypan, which must be a small lake after rain. J 

 E. lacunaria, F. v." M. Moorilyanna Native Well. [A 

 common grass amongst the granite rocks; a good fodder 

 grass.] Stipa scahra, Lindl. Musgrave Ranges. Leafblades:
