at different times of the year. Eria densa has the flowers nearly 
white in the lower part of the hills, but above 2000 feet alt. they 
are vinous purple.

Sarawak (Bishop Hose. V.v.). 
A very remarkable plant, allied to Z. floribunda, Lindl., with 
the stems narrow and slender at base, suddenly dilated for the 
uppermost three internodes, which are much enlarged laterally 
and vertically, and bear each a dark green terete leaf. In drying 
the fleshy internodes shrink, so that dried specimens do not give 
the exact appearance. The flowers resemble those of Z. flori- 
bunda, Lindl. I have twice received this alive from Sarawak. 
There is a figure among Scortechini’s drawings of Malay orchids 
which I suspect is meant for this, but I have not myself seen it 
in the peninsula.
