1. A. Colensoi, Hook. /., Handbk. 92. Erect, glaucous when young. 

 Stem 2ft.— 4ft. high, 2in.— Sin. in diameter, furrowed. Leaves 1ft.— 2ft. long, 

 with a pair of simple or divided spines lin.— 4in. long at the mouth of the 

 sheath, pinnate or rarely the leaflets 2-pinnate ; segments excessively coriaceous, 

 thick and rigid, narrow-linear, 5in.— 9in. long, 4in.— fin. broad or more, acumi- 

 nate, forming a mass of bayonet-like spikes 2ft.— 3ft. across ; margins rough, 

 scarcely serrulate. Umbels in the axils of dilated 3— 5-partite spinous bracts. 

 Male: 2in.— 6in. long; umbellules numerous, whorled ; calyx-teeth minute, 

 very acute. Female : less crowded ; peduncles 2in.— Sin. long, with 3-5 short 

 simple umbels at the base; rays unequal, iin.— fin. long, with a few pedicellate 

 flowers in their axils; pedicels short, slender; calyx-teeth acute. Fruit ^gin. 

 long, broadly oblong. Carpels usually with 4 wings, or one 3-winged with 

 2 intermediate ridges ; vittae 5 on the commissural face and 1 beneath each

 lules more lax and pedicels longer than in the type. 



SOUTH Island : frequent in the mountains of Nelson and Canterbury. Greater-spaniard. 

 Probably a distinct species. 



Distinguished from all other species by its robust habit, broad leaf-segments, and large fruit. 

 It yields a semi-transparent gum-resin. The spines at the mouth of the sheath are sometimes 

 produced into leaflets.
