Snapdragon, genus Antirrhinum, commonly called dragon flowers

Inside a snapdragon flower

It has been said that these flowers resemble a dragon’s face.  The ‘mouth’ of the dragon opens and closes.  The flower is actually ‘bilabiate’, or two-lipped, and the lower lip is used as a landing pad for pollinators who visit the flowers.  These flowers also have what is called, ‘personate’ floral shape.  Snapdragons used to be placed in the Scrophulariaceae family, but have now been grouped into the Plantaginaceae family.

When one opens the flower, one can plainly see four distinct stamens with yellow anthers (pollen), at two different heights.  These are called ‘didynamous stamens’, and they’re a common diagnostic characteristic for this family.  If you look closely, you can see a greenish ‘stigma’, or female part of the flower located in the center of the four stamens.

Several snapdragons are now blooming at the south end of the Tucker Greenhouse, making it feel much more like spring.

The most dangerous job on campus

When a pane of glass breaks on the walls or the roof of the Tucker greenhouse, it is the job of a Campus Facilities carpenter to fix it.  On Monday, the crew showed up to replace three broken panes that were about 30 feet in the air.
