off and even if stumps are left standing, Hedychium makes its 
appearance everywhere. This at first sight is difficult to account 
for, but on penetrating into the uncleared jungle one can see 
that H mente is already there waiting to make itself evident. 
saw how it taken possession of lands cleared for sugar- 
cane and how it had taken possession of any piece of cleared 
and. The next thing after clearing for sugar is to clear from 
Hedychium. It is quite evident therefore that in this district 
particularly the growth of Hedychiwm can be stimulated almost 
illimitably. The soil is rich, the rainfall heavy and the land 
is interspersed with small streams. It is not necessary that the 
land should be flat, in fact, it grows abundantly on slopes and 
on the a of steep yal cuttings, ete

This is ie had port ne Paranagua, and likely in time to 
become an important port for Curityba. Here, again, stems

I Rectacled the fibre from the green plant by mechanical 
means, imitating methods that would be employed for the pre- 
paration of the fibre for textile purposes, and came to the con- 
clusion that a far whiter fibre may be extracted than has hitherto 
been employed by taking fairly simple nome; 
I visited’ various localities until we reached Rio Grande in 
the most southerly part of Brazil, ska Uruguay, across the 
Argentine, up the Chilian and Peruvian Coasts, and y came 
through the Panama Canal, and although I eeaied pis Ast 
I did not see any H edychium after leaving the State of Parana. 
which Hedychium may be expected to flourish in those parts of 
the British Empire where favourable conditions prevail.

The present contribution is the outcome of further collections made 
by Mr. C C. O. Farquharson in South Nigeria during the period age oe 
viously recorded forms. Six species new to science were obtained ; 
two of these, Polystictus pyrophilus ar Lee pulverulentus, have 
already been described (Kew Bull. No. 3,

in 1914 to be causing a distinct disease of Para rubber in Niger.
