Drosera rotundifolia – sundew

Drosera rotundifolia or sundew is a carnivorous plant that is often found in bogs or marshes. This 30cm model represents a leaf only 4-10mm in size. The leaves grow on a long peitiole with club shaped hairs on the surface and secrete a clear sticky fluid which attacts and traps insects. When an insect is caught the hairs bend inward and the leaf curls around the insect. Enzymes secreted by the hairs as well as bacteria digest the insects and nutrients released from the prey are then absorbed by the glands that secrete the digestive enzymes.

Nepenthes destillatoria – pitcher plant

The pitcher plant is a carnivorous plant which traps prey in a pitcher shaped leaf modification growing from an extension of the leaf midrib called the tendril. The cup shaped trap contains fluid secreted by the plant in which the prey (usually insect) are trapped and drown. The lid or operculum over the pitcher may keep rain from diuting the fluid. Nutrients are absorbed by glands in the lower part of the cup.

Pisum sativum – pod and peas

The pea is a member of the legume family Fabaceae in the order Fabales. This is the 3rd largest family of flowering plants and contains many commercially valuable species.

This model shows the structure of the pea seed pod, also called legume. The model opens to show the arrangement of the seeds (peas) inside.

The collection also contains a model of the flower of this species.

Pisum sativum – Pea flower

The pea is a member of the legume family Fabaceae in the order Fabales. This is the 3rd largest family of flowering plants and contains many commercially valuable species.

This model shows the specialised structure of the pea flower with its combination of fused petals and interesting arrangement.
The collection also includes a model of the legume (pod) containing seeds (peas).

Brassica napus – rape

The Brassica genus, also known as mustard or cabbage family of plants contains an enormous number of commercially valuable species.  Brassica napus, also known as rape or rapeseed (one of the more recent cultivars is canola) was of value in the 19th century as a source of lubricant for steam engines.

This model is designed to come apart to show detail of the internal flower structure. The attention to detail of form is beautiful right down to venation of the petals.
