Subgenus iv. — Junci aeptati^ Fr. Buch. 



This group contains all the Australian species the leaves of 

 which are more or less distinctly jointed from internal cross par- 

 titions of the pith. 



12. ./. jmsillus^ Fr. Buch., Abh. Nat. Ver. Brem. vi. p. 395 

 (1879); J. capillaceus, Hook, f., Fl. Nov. Zel. i. 264 (1853), B.Fl. 

 vii. 132. — New South Wales, Victoria, Tasmania. 



Hooker's name capillaceus has to give way to Buchenau's name 

 piisiUus, because the former name has been previously bestowed 

 by Lamarck on a South American species of Juncus. Mueller 

 united it in his Census with the Chilian species J. stipulatus, 

 Meyen and Nees, a union which is not followed in the latest Kew 

 publication, nor by Prof. Buchenau. 



Bentham's description of J. jyrismatocarpus includes J. holo- 

 schoemis, an unnatural union, as Mr. E. Cheel has pointed out 

 (these Proceedings, 1902, p. 210), a view fully approved of by 

 Prof. Buchenau. 



Buchenau describes four species in this group (besides J. 

 pusillus), viz., J. prismatocarpus^ holoschcenus, Fockii and lampo- 

 carpus, which are all common in the Port Jackson district, and 

 are doubtless mixed up in most Australian herbaria with J. pris- 

 matocarpus. To clear up the confusion, we give here a short 

 description of the four species, extracted from Buchenau's 

 ' Monograph,' and a short key of the most conspicuous though 

 not always most important characters : — 



1. Stamens 3. Leaves indistinctly septate, pluri- 



tabulose 13. J. prismatocarpus. 



1*. Stamens 6. Leaves distinctly septate, uni- 

 tubulose.
