RANUNCULACEAE - Buttercup Family
Flowers of Clematis; the right one is more mature. Only the calyx is present, a common feature of the Ranunculaceae family; ie. the perianth is composed of entirely sepals.
A cross section through the flower with parts labeled.
A pistil under the microscope. The tip is the stigma, the furry bits are the style and the oval structure at the end is the ovary.
When the fruit ripens, it will look like this. Each individual pistil matures into an achene.
The zygomorphic flowers of Aconitum and again, the petal-like structures are actually the sepals.
The pair of elongated structures hidden beneath the 'hood' are the modified petals. The petals are comprised of 3 parts: claws, spur and blade
Check out the spirally arranged stamens. How many pistils are present? I forgot to count during the lab, but my guess is 3?
The fruit of Aconitum is a follicle. It is characterized by its single carpel and dehiscing to release its seeds.
