Mesemb seed capsules Derek Tribble's informative and detailed display showed the seed capsules of various mesembs. Nearby was a water sprayer to mist and open the fruits. In habitat rain opens the fruits and raindrops distribute the seeds at a time when germination is more likely. Also available was a hand lens to enable visitors to see the intricate mechanism of the capsules. Differences in these structures are important in distinguishing the genera in the family. |
Right: This
detail of the display illustrates the variation in size of the fruits,
even between species in the same genus, (Cheiridopsis).
On the far right is a closeup of the capsule of Cheiridopsis peculiaris, one of the biggest on display. Some idea of the complexity of the capsule structure is visible in this open fruit. Thanks Derek. |
