appear furrowed underneath on account of the shrinking of the 

 tissue between the three strongest ribs. New South Wales, 

 Victoria, Tasmania. 



3. J. homalocauHs, F.v.M.; B.Fl. vii. 128. New South Wales, 

 Victoria, South Australia, West Australia. 



4. ./. tenuis, Willd. Not recorded by Bentham and Mueller 

 from Australia. 



A slender perennial allied to J. Broivnii, F.v.M., from which 

 it is most conveniently distinguished by the two long leafy bracts 

 at the base of the inflorescence which generally much exceed the 

 inflorescence, while J. Broivnii has a single leafy bract at the 

 base of the inflorescence scarcely exceeding it. J. te7iuis is so 

 common in the Port Jackson district that it must have been 

 collected frequently, but probably has been mixed up with J. 

 Brownii, a mistake all the more likely as Bentham himself seems 

 to have mixed up the two species in his description oiJ. revolutus. 

 (He writes, B.Fl. vii. 128, "Flowers . . . with one or two 

 leafy bracts at the base of the cyme "). 



It seems to be not ivwXy indigenous to Australia, but this is a 

 very difficult question to decide, especially as so many J unci are 

 almost cosmopolitan; however, we can only say that all our speci- 

 mens are from cultivated ground, and that we have not seen a 

 specimen from beyond the Port Jackson district. 



Subgenus ii. — Junci gemdni, Fr. Buch. 



The chief character of this Section of Junci is the inflorescence, 

 which is terminal, but has quite a lateral appearance on account 

 of the lowest bract being erect, continuous with the stem and 

 completely simulating the stem. Bentham includes four Austra- 

 lian species in this group — J. coyniinutis, E. Mey., J. vayinatiiSy 

 K.Br., J. paucifforu.<; R.Br., J. pa/lidus, R.Br. Fr. Buchenau 

 divides the Australian Junci of this group into five species, to 

 which he now adds J. Jiticaulia as the sixth. 



5. J. filicaulis, Fr. Buch. New South Wales.
