Colla's plant is certainly this rather than Cyperus vegetus, which Gay says it resembles ; 

 in fact, Bertero's specimens in the Kew Herbarium agree very well with Colla's rude figure.

1 Mr "W. Mitten sends cultivated specimens of a Juncus "raised from seeds shaken out of Juan Fernandez 

 mosses." It is a very slender form of Juncus effusus, Linn., or a closely allied species. Dr Buchenau, to whom 

 an imperfect specimen was sent, suggests that it may bo Juncus pauciflorus, R. Br., a common Australian species ; 

 but, in the absence of more complete specimens, the species is indeterminable.
