| Examples of this are furnished by the cardiac muscle of the animal, the pulvinus of Mimosa, and the stamen of berberis. |
| The pistil and the stamen of the flowers are the specialized organs responsible for the reproductive processes. |
| Penstemons are sometimes commonly called beardtongues because the sterile stamen has a tuft of small hairs. |
| The stamen primordia differentiate from globular primordia into elliptic appendages of differing size. |
| In some species the ten stamens are all united by their filaments or one stamen is free and the other nine are united. |
| We also have the species Astrantia major with green flowers filled with pinkish stamen which quiver in the slightest of breezes. |
