After leaving the convent, I hired a boat in order to proceed a few miles further up the bay, and landed on a peninsula called Bomfim, across which I walked, accompanied by one of the two blacks belonging to the boat, the distance being rather less than two miles. After leaving the shore, on which grew _Sophora tomentosa_ and _Eugenia Michelii_, two shrubs common all along the coast of Brazil, I passed through a marsh containing several species of plants that were new to me. Beyond this, the road passed through a dry sandy hollow, in which not a breath of air was to be felt, and the rays of the mid-day sun, reflected from the white sand, had so heated the atmosphere, that I was almost suffocated before I could reach a little eminence at the other end of it. Here, also, I enriched my collections, and still further on I found the thistle-like _Ampherephis aristata_ growing commonly by the road-sides; and some large pools in a marsh, under the shade of a thicket of giant palms, were quite covered over with _Pistia stratiotes_, a plant nearly related to the Duck-weeds of England, but of a much larger size; other pools were gay with the yellow flowers of _Limnanthemum Humboldtianum_. After reaching the shore I walked along it a little way, and then returned to the boat by a different route. In passing through a swampy place at the foot of a hill, on which a large church stands, I found a few specimens of the beautiful _Angelonia hirsuta_, with its long spikes of large blue flowers. I afterwards met with several new species of this fine genus, some of which, raised from seeds sent home by me, are now common in hot-houses.
