I got in december thorelii (d) x truncata (c). It's in my lowland terrarium where I've got temperatures of 30°C at daytime and 23°C at nighttime.

EP sells this plant as small. I've got no idea what they would consider as big because in my sense this plant is big. It thrives excellent under the hot conditions. Here is a photo of it:
