318 NOTES FROM THE BOTANIC GARDENS, SYDNEY, No. 13, 



Scirpus Kochii, n.sp. 



Cowcowing, Australia Occidentalis (Max Koch; September 

 mensis mdcccciv). 



Planta annua caespitosa caulibus fere filiformibus et 

 costatis, maxima altitudo sex uncise. Folia setacea, brevissima, 

 vagina brevis et coloris badii. Spiculae sesquilineam usque ad 

 plus quam duas lineas longae, plerumque tres usque ad quinque 

 in racemo terminali. Bractea foralium plerumque una sola, quae 

 expandit vel erecta est, et variat a breviore quam spiculae usque 

 ad fere unam unciam longa. Bracteae florigerae irregulariter in 

 quinque ordinibus ordinatae, fere ovatae, carina firma et fusca 

 continuata in acumine brevi et recto vel curvatiore, latera pallida, 

 pellucida, omnino nervis carentes, sigillatim rugosa. Setae hypo- 

 gynae absunt. Stamina non vidimus. Stylus tribus ramis. 

 Caryopsis ovata, lsevis, tribus angulis distinctis coloris schistacei, 

 circiter tertia pars tarn longae quam bracteae florigerae. 



A small tufted annual at the most 6 inches high, with slender 

 almost filiform ribbed stems and shorter setaceous leaves; the 

 short sheath at the base of the stems reddish-brown. Spikelets 

 1J to above 2 lines long, generally 3 to 5 together in a terminal 

 cluster. Involucral bracts mostly 1 only, spreading or erect, 

 generally somewhat longer than the cluster of spikelets, but 

 occasionally shorter, or nearly 1 inch long. Glumes numerous, 

 irregularly arranged in five rows, almost ovoid, strongly keeled, 

 the brownish keel produced into a short straight or slightly 

 recurved point, the sides pale and quite nerveless, transparent, 

 minutely rugose. No hypogynous bristles. Stamens not seen. 

 Style-branches 3. Nut ovoid, smooth, prominently 3-angled, 

 about ^ as long as the glumes, of a pale slate colour. 



This graceful Scirjms is nearly allied to S. cartilagineus, but 

 the small nuts and the transparent glumes without any side-nerves 

 distinguish it sufficiently from this species and all its forms. 



Rhynchospora aurea Vahl. New for New South Wales. 

 Connungra, near Mt. Lindsay (J. L. Boorman; March, 1904).
