P. camjohorata seems to be a polymorphic species as regards the 

 arrangement and the surface-covering of the leaves, varying from 

 opposite to alternate in var. laevigata, alternate in the other forms, and 

 from entirely glabrous in var. laevigata to densely setose all over the 

 surface in var. armata. These differences, however, are not associated 

 with any others, the flower-heads being identical in all. 



19. P. stricta, Ait. Hort. Kew, ed. I. iii. 162. 



A shrub ; branches strigose-pubescent. Leaves dense, clustered or 

 alternate, acicular, acute, subterete, 1-2 cm. long, fleshy, with a few 

 cilia on the lower part or sometimes nearly glabrous. Heads corymbose 

 at the ends of the principal branches, each terminating a short lateral 

 branch, campanulate, about 2 cm. long and about 15 cm. in diameter. 

 Involucral bracts 5-6-seriate, exceeding the flowers, greenish when 

 dry, all linear or linear-lanceolate, conspicuously tailed-acuminate, 

 and very prominently ribbed, very slightly ciliolate, otherwise 

 glabrous. Receptacle honeycombed. Corolla green ? about 1 cm. 

 long, ribbed and sparsely puberulous in the lower part, gradually 

 widened from the middle upwards ; lobes lanceolate, subacute, 

 1'5 mm. long. Achenes glabrous, somewhat flattened and elliptic 

 when ripe, 5 mm. long, smooth and shining, with thickened lighter
