MR. WEIR'S JOURNAL. 235 
Oct, 6th.— Left Fachina after breakfast. Road over eria collected 
n the way specimens of Nos. 287 (Oxalis myriophylla, St. Hil.), a 
small yellow-flowered oxalis; 288 (Diplusodon sp.), a а tect shrub, 
with large white flowers, height 4 to 5 feet; 289 (Mimosa sp.), an acacia, 
with pink or light purple flowers, height 4 to 5 feet; and 290, a small 
creeping coments species from moist places. All these species are 
from the с 
Oct. Tth. pa five more leagues of campo to-day, and halted at the 
river Itararí, which here forms the boundary between the provinces of Sao 
Paulo and Parana. 
The sandstone we saw for the first time at Fachina still continues, and 
the country now presents peculiarities not observable until we entered 
upon this rock. The campos are more beautiful than those we have left 
behind, being covered with a closer He, and a greater variety of 
species. They are not flat, but for the most part consist of gently roll- 
ing ridges, the valleys between them m somtimes swampy, but 
oftener they are occupied by streams of beautiful clear water, running 
often worn into deep canals by the water, and the bottom is full of deep 
holes of all sizes and shapes from the same cause. "These streams are 
Ze by the people here **lageadas " (pavements), Almost all the rivers 
t. Paul's are mud bottomed. 
"Th e rock is often near the surface, and sometimes juts out of the sides 
of the rolling hills, forming rugged naked EM 
Brazilian Araucarias too are becoming much more frequent, the 
сарабз or patches of forest on the campo being now often thickly varie- 
gated by them, and there are many small groups and single trees of them 
scattered over the landscape. 
The river Ttararí runs in a very deep chasm, either worn by the water 
or formed by a crack in the rock. The mouth of this chasm is not more 
than eight or ten yards wide, and its depth cannot be less than eighty feet : 
from its narrowness and darkness, and from the numerous projections in 
its sides, it is only here and there that a glimpse of the river can be had, 
boiling and struggling in its narrow channel at the bottom of the chasm. 
Near the top, the drippings are thickly covered with Sphagnum, Tricho- 
manes, and other ferns, 
Of the following species I collected specimens to-day: — No. 290, 
from damp rocks; No. 291 (Manettia, n. sp.), from campo; No. 292 
(Iethyothere, n. sp), а true Solanum, from а сараб we assed ; No. 293 
(Petunia thymifolia, Miers), a pretty and very dwarf-growing Petunia, 
with rose or light purple flowers; and No. 294 (Coffea sp.), a shrub from 
E 9th.—Still wet, but there have been a few fair intervals in the 
afternoon. During the fairer part of the day I went out to look about the 
brink of the chasm, in the hopes of finding some plants in flower, and 
collected specimens of the following :— №. 296 (Leucothoe nummularia, 
D. С.), а shrub 6 feet high; No. 297 (Hedyotis muscosa, "St. Hil), 
from damp places among the grass; No. 298 (Anacardium t St.
