CALISAYA-YIELDING DISTRICTS OF EASTERN BOLIVIA. 323 
On the European continent, Scirpus parvulus occurs in several scat- 
tered localities—on the shores of the Baltic and German Ocean, and on 
the Atlantic and Mediterranean coasts of France, extending to Sardi- 
nia and Italy; but though its range is wide, it appears to be a very 
local and rare species. Godet, in his * Flore du Jura,’ mentions a lo- 
cality on one of the lakes; but as Godet compares his plant to Scirpus 
pauciflorus, and as all the other stations are upon the coast or along 
tidal estuaries, it would appear safer to consider this inland habitat as 
uncertain for the present. It may well be expected that S. parvulus 
will be found in other parts of Britain; for instance, in some of the 
muddy estuaries along the mouth of the Thames, in Poole harbour, and 
other places in the south and south-west coasts of England, and in the 
south of Ireland. I presume that Mr. Watson would treat it as a 
member of his ** Atlantic type " among British plants. 
I have not succeeded in finding ripe fruit on the Irish plant, which 
appears to propagate itself by means of the little tubers.

FRESH EXPLORATION OF THE CALISAYA-YIELDING 
DISTRICTS OF EASTERN BOLIVIA, BY SENOR PEDRO 
RADA. 
By J. E. Howarp, ESQ., ELS: 
The European market has hitherto been supplied with the precious 
quinine-yielding barks of Bolivia, solely by the ports on the western 
t ica, Iquique, and others which have suf- 
fered in the late calamitous earthquake, were the terminal points to 
which the serons (or packages of bark covered with the hides of oxen) 
were brought after a long, expensive, and difficult overland journey, 
over radi too often a ndoned to neglect by the administrators of 
Bolivian affairs. The result was, that on the eastern side of the 
that furthest from the sea, large tracts of 
country, and, consequently, 9
