66 CARYOPHYLLE. [Colobanthus. 
Colobanthus repens, Col. in Trans. N.Z. Inst. xix. 261, and C. caspitosus, 
Col. /.c. xxvii. 384, are respectively Sagina procumbens, Linn., and S. apetala, 
Linn., as proved by the type specimens in Mr. Colenso’s herbarium. It is 
curious that such an acute observer as Mr. Colenso should have overlooked that 
the stamens are opposite to the sepals in both these plants, and not alternate, as 
is the case in all true Colobanthi. Both the above species of Sagina are now 
copiously naturalised throughout the colony.
