Morphology
Monocotyledonous Plants
The family of monocotyledonous plants includes grasses, orchids, lily plants and palms. There are more than 66,000 different species
worldwide.
Wheat (Triticum aestivum)
Model of a spicule magnified
15 times, with removable and
dissectible single flower.
52 cm; 0.8 kg

Grasses
The narrow, sharp and parallel running leaves are typical of the ger-
mineae genus. The air pollinated and generally androgynous flowers
are arranged in heads.
Tulip (Tulipa gesneriana)
The section of stamen and pistils is
removable, 3 times magnification.
51 cm; 0.4 kg

Lily Grasses (Liliaceae)
Lilly grasses are characterized by bulbs and their large, funnel shaped
flowers.
Dicotyledonous Flower
The pollination of the angiosperms can be taught using this magnified
model of an idealized flower with, torus, ovary, and style.
Removable are:
• 3 petals
• 4 sepals
• 4 filaments
2 anthers and the ovary
are cut partly to
show the inner
structures. 6 pollen
grains that are mount-
ed on the style can be
easily identified.

Dicotyledonous Plants
The family of dicotyledonous plants includes the majority of angiosperms and all woody plants. There are more than 174,000 species
world-wide.
Sunflower
(Helianthus annuus)
The model shows the inner tubular
corolla magnified 10 times and the
outer ray flower magnified 3 times.
The tubular corolla can be dissect-
ed into 2 halves. 24 cm; 0.5 kg

Composite Flowers (Asteroideae)
Typical of the asteroideae species is the torus mostly featuring many
single flowers, which are surrounded by a mutual involucre. Asteroi-
deaes are often useful or medicinal plants.
