374 NOTES FROM THE BOTANIC GARDENS, NO. XL, 



CYPERACE^. 



Lepidosperma lineare R.Br. 



Warialda (J. L. Boorman; Aug. '05). 



Most northern locality of a plant common in the southern parts 

 of Australia, from Tasmania upwards. 



RHIZOSPEEM^. 

 Marsilea angustifolia R.Br. — New for New South Wales. 



Gilgunnia (W. Bauerlen; No. 3175; Jan. '04). 



Small plants with a filiform rhizome. Barren fronds glabrous, 

 on filiform stalks from 1 to rarely above 2 inches long, the 

 leaflets narrow-cuneate, 2 to rarely 3 lines long and f to 1 line 

 broad at the top, entire or obscurely crenate. Sporocarp solitary, 

 shortly stalked or almost sessile, covered with very short appressed 

 hairs, nearly horizontal, about 1 line broad and IJ lines long, 

 only the lower tooth developed, obtuse. 



Previously recorded by R. Brown, Bentham, and A. Braun 

 only from North Australia. Mueller unites all Australian species 

 under one name, so that his ' Census ' is no guide to the distribu- 

 tion of the various species. 



It is not possible to identify M. angustifolia from R. Brown's 

 original brief description of six words : " foliolis lanceolatis apice 

 subdentatis; adultis glabris " without type-specimens, but from 

 Bentham's description in the 'Flora Australiensis,' and Alexander 

 Braun's description in his classical paper ' Neuere Untersuchungen 

 iiber die Gattungen Marsilea und Pilularia " (1870), we have no 

 doubt that Mr. Bauerlen's Gilgunnia specimens are the dwarf 

 narrow-leaved form mentioned in both papers. F. M. Bailey 

 figures M. angustifolia with lanceolate acute leaves ('Queensland 

 Flora,' Part vi. p. 1929, t.87) but describes the leaflets in the 

 same place as truncate, copying literally Bentham's description 

 in the ' Flora Australiensis.' 



The most striking feature in the Gilgunnia specimens is the 

 distinctly pinnate arrangement of the leaflets, in contradiction 

 to the erroneous but quite popular conception that Marsilea has
