 Shoots erect, 30 cm. more or less long, simple, angular and grooved in 



the lower Y s /s, branched upwards, with the branches and leaves liable to 

 curl up in drought; pinnae not copious, 2-pinnate, with the branchlets simple 

 or forked; ultimate branchlets to 2 cm. long, 23 mm. broad including the 

 lateral leaves. Leaves of the stipe and lower part of the main rachis 

 isomorphous, erect, triangular-subulate, the margin spinuloso-ciliate, the 

 base cordate; leaves of the branches heteromorphous ; lateral leaves 

 somewhat remote and subspreading on the rachises, more or less contiguous 

 and erecto-patent or slightly remote and subspreading on the branchlets, 

 those of the ultimate branchlets falcate, to IVa mm. long, to nearly 1 mm. 

 broad, firm, the apex very acute or sharply acuminate, both edges con- 

 spicuously and more or less remotely setulose or spinuloso-ciliate towards 

 the base, gradually more or less sharply dentate or denticulate towards 

 the apex, the base broadly adnate, with the free corners narrowly rounded 

 or the lower one narrowly truncate; intermedial leaves lanceolate, 

 those of the branchlets 1'A IVa mm. long, J /2 3 A mm. broad, sharply 

 acuminate, the margin remotely setulose or spinuloso-ciliate towards the 

 base, more or less sharply dentate or denticulate towards the apex, the 

 base very oblique, cuneate on the inner side, produced and cuneate to 

 cordate on the outer side. Spikes to 2 cm. long, square or nearly so, 

 2 mm. diam.; sporophylla isomorphous, ovate, VU mm. long, acuminate, 

 keeled, remotely setulose or spinuloso-ciliate towards the base, more or 

 less denticulate or dentate towards the apex; macrospores yellowish-white, 



densely and finely verruculose to rugulose; microspores Very 



distinct by its conspicuously acute and spinuloso-ciliate leaves, which give 

 the whole plant, when seen under the lens, a thorny appearance.
