But wait, is not the "tuber" of tuberous Drosera more like a potato than an
onion?
A bulb usually consists of a rather small amount of stem tissue, with an
apical meristem. Bulbs often are encased in many layers of leaves,
dried and papery to the exterior, but the inner leaves being thicker and
fleshy, acting as the primary storage organ. In a tuber the stem itself
is the primary food storage organ. I have never noticed tubers on tuberous
drosera to be ensheathed by leaves. Perhaps the tuber of the tuberous
Drosera would be better described as a CORM?
