Orchid tubers! Thought I'd share some pics of these wonderful little things. Unfortunately I couldnt find my ruler, but I'll upload some pics with a ruler once I find it.
The largest Pecteilis susannae tuber is about twice as large as the Nervilia punctata tuber which is a bit bigger than the Nervilia plicata tuber.
1. Nervilia punctata, 1 week into dormancy.

2. Nervilia plicata, 1 day into dormancy (4 more plants have yet to go dormant).

3. Pecteilis susannae, 1-1.5 months into dormancy.
Only Nervilia campestris has not become dormant at all.
