The summit of one of the highest mountains, which I visited this day, for the first time, was formed of calcareous stone disposed in strata almost horizontal, similar to those which I had before met with on those heights. It was of a very fine grain, with some few small cavities. I did not there observe any shells. It may be presumed, that that conformation was the effect of a flow deposition of calcareous matter in a state of solution.
The change of the soil presented me with some plants, which I had not yet found.
I gathered a new species of very tall (saillante) eucalyptus, of which the following is a description:
The most elevated twigs of that shrub, are not above thirteen feet in height. They are smooth, are furnished, chiefly towards the extremity, with leaves, alternate, oval, elongated, slightly bent, and about four inches in length.
The flowers are sessile, and generally eight or ten in number, at the extremity of a common peduncle, about an inch and one-fifth in length, having all the characters of the genus eucalyptus. Their stamina, which are very numerous, have long filaments of a yellow colour. The style projects a little over the stamina.
The calix is very much elongated, and is
pushed
