MOSQUITO LARVA: IN THE PITCHERS: 
OF NEPENTHES. 
Towards the end of last year, on examining the contents of 
a pitcher of the common pitcher plant (Vepenthes ampullacea, 
Jack) which was growing in the jungle in the Botanic Gardens, 
I was surprised to find three larve of one of the mosquitos 
living and apparently thriving in the water of the pitcher. 
Carefully cutting off the pitcher and keeping it in a bottle, I 
succeeded, in two or three days, in rearing two of the larve 
to maturity. That mosquito larve are not very particular as 
to the water they live in is known to every one who has ever 
watched them, but it is certainly very remarkable to find them 
living and thriving in the liquid in the Nepenthes, which is so 
speedily fatal to any other insect which chances to fall in.

MATONIA PECTINATA IN THE KARIMON 
ISLANDS. | 
During a short trip recently made to the Karimon islands, 
I came across a great quantity of Watonia pectinata, growing 
with Dipteris Lobbiana and D. Horsfieldit, near the waterfall, 
which is certainly not more than 500 feet above sea level. 
This rare fern is not known to grow elsewhere at a lower 
altitude than 2,000 feet. Yipterts Horsfieldii, itself so abundant 
on the shores here near Kranji, in Johor, Toas, Pasir Panjang, 
etc.,is an alpine or subalpine plant only in Java growing 
at about 4,000 feet altitude.
