Botany picture #71: Calotis glandulosa
Calotis glandulosa (Asteraceae), Australian National Botanic Garden, 2013. The genus Calotis has very characteristic spiny and/or winged fruits which provide the major characters for identification. The spinier species are known as "bindi", and it is very unpleasant to step on them or to get them into your boots during field work, as I know from experience. Unfortunately, many of them are very hard to tell apart without the fruits. This is one of the prettier species and also fairly easy to recognize due to its strikingly glandular indumentum. Others often have smaller flowerheads, either also in purple or often in yellow.
