Amongst introduced grasses that are widely spreading 

 are : — 



Ktzlaria phleoides, Pers., throughout central districts and 

 islands of Bass Straits. 



JBracleypodium distachyum, JR. et Sch., on the Domain in and 

 about the Botanic Gardens. Referred to in Spicer as a 



Triticum. 



Gastridium lendigerum, Beanv., the common nitgrass of 

 the northern hemisphere, is dispersing itself in the Berriedale 

 neighbourhood. 



Panicum sanguinale, Linn., a fingered grass of world-wide 

 distribution, is appearing in a few districts. 



Polypogon littoralis, Linn., is also becoming common on the 

 river swamps below Bridgewater. 



Lepidosperma falcata, n.s. Densely tufted. Leaves flat, 

 not acute, about \ to f line diameter, spirally curved, about 

 6in. long, stems similar. Panicle simple, few flowered, each 

 pedicel curved. Glumes few, obtuse, inner pair much exceed- 

 ing the rest and widely gaping when the nut is mature. 

 Nut shining, obscurely triquetrous. Hypogynous scales 

 thick and short below the nut as in L. lineare. Common in 

 poor soil, in healthy and stony places in Tasmania. 



Itis with considerable hesitation I describe this as specifically 

 distinct from L. lineare, R. Br.; but it could not be included. 

 in that species without also including both with L. laterals, 

 R. Br., a clubbing hardly justified though natural. 



Carex barbata, Boott. Tufted. Leaves about 1ft. long, 

 rather narrow, without a conspicuous mid-rib, margin scabred. 

 Stems slender, 12-18in. high. Spikelets few, stalked, the 

 upper one male, but often bearing also a few female flowers; 

 the female spikelets often with few male flowers at the apex, 

 about lin. long. Glumes and utricles similar to those of 

 C. gunniana, Boott, but the latter only half the size. 



Common in swamps at Claremont and Longley. 



This species, which I apprehend to be the Carex barbata of 

 Boott referred to in Bentham's Flora Australiensis, lives 

 with 0. gunniana, and though similar in general habit, is 

 most undoubtedly distinct from that species. 



Corysanthes unguiculata, R. Br. This rare and interesting 

 little orchid occurs near Kingston, in damp heaths, and will 

 probably be found in suitable localities.
