the narrowness of the fruit, the calyx is attenuated between the aristae, and the mouth of its tube generally terminates in four recurved points ; the petals are longer and narrower and the stamens very small, with filaments even shorter than the anthers ; the latter were invariably full of pollen and quite perfect.

I have not met with this small and very distinct species either in flower or fruit, nor does it exist in any other collection of Fuegian plants than my own and that of the late Mr. Menzies.
Below[1] are descriptions of two additional Acana, which, with the above and four others in De Candolle's Prodronius, include all the South American plants of this genus, known to me.
