This is a strange looking N. fusca that I received from Jack and Jeanie at Hawaiian Botanicals via Borneo Exotics. (If any of you ever end up in Richmond BC, be sure to drop in at their greenhouse/nursery and say hi. They are very friendly folks and have a great little place there. Unfortunately they only ship within Canada though.)
The pitchers have a flared striped peristome on a needle thin wasp waisted waif of a pitcher body.
Here is an older pitcher.
The leaves are also strangely truncated and heart-shaped.
Here is a closer shot of the upper half of the newest pitcher to open. The peristome will darken over the next little while.
This is still a small plant, so it will be interesting to see what it starts to look like as it matures some more.
