BOTANICAL INFORMATION. 483 
help thinking is my old Brazilian acquaintance, Polystachia 
luteola. Mr. Newman had once found Ophioglossum pendu- 
lum at this place, but could not again meet with it. Itis a 
rare plant, but I have a specimen of it among the ferns I 
received from M. Bojer. Among the flowering plants I 
met with here, I may mention the beautiful Ochna Mauri- 
tiana, Hugonia serrata, a Mussenda, a Gertnera, two spe- 
cies of Memecylon, several species of Jossinia, and a few 
Rubiacee. Near Pamplemousses I found all the ponds 
covered with the floating leaves and beautiful blue flowers 
of the Nymphea stellata. 
My second excursion was, however, by far the most inte- 
resting. This was to the summit of the mountain called La 
Pouce, which stands at the head of a valley which runs 
inland from Port Louis a few miles, and which rises to the 
height of two thousand six hundred feet above the level of 
the sea, The vegetation on this mountain may very natur- 
ally be divided into three regions. The first, which reaches 
tothe height of about one thousand eight hundred, is the 
least interesting portion. The plants which appeared to be 
the most abundant on it, were the following: An Acacia very 
like 4. Farnesiana, but not in flower, Rhamnus lucidus, 
a Celastrus? Clerodendrum heterophyllum, two species of 
Diospyros, Quivisia heterophylla, great abundance of Jas- 
minum Mauritianum, Erythroxylum hypericifolium, Ehretia 
peliolaris, Dodonea salicifolia, a Prockia, an Eugenia, Pteris 
lanuginosa, and Adiantum rhizophorum. The second region 
18 comparatively flat being perhaps about a mile in length, 
It is much better wooded, and is very rich in plants, particu- 
larly ferns, and on the whole reminds me very much of some 
Parts of the Corcovado mountain near Rio, only that they 
are much smaller, I cannot of course, name all the ferns in 
mean time that I met with here; but among others, I 
may mention the following: Davallia tenuifolia, which is a 
Most beautiful plant when growing in a mass. It covered 
Many yards of the banks of a small stream, the latter being 
as common here as it is on the mountains around Rio
