The antirrhinum is, so to speak, a closed box, of which the Humble Bees alone possess the key. |
However, an extra element of patterning is required in the Antirrhinum flower, which has a bilateral symmetry imposed on the basic radial pattern common to all flowers. |
In contrast to the advances in genetic and molecular studies, little is known about Antirrhinum cytogenetics. |
The colourful, fat tubular flowers of the Antirrhinum, with their snapping 'dragon mouths', have long held a fascination for small children. |
The phenomenon is not confined to woody plants, but has been met with in chicory, in antirrhinum, and other herbaceous species. |
There's Tutti Frutti, a new lupin with bicoloured flower spikes, Tequila Sunrise, a bronze foliaged antirrhinum, and Creme Brulee, a new phlox, all from Thompson and Morgan. |
