===Fronds: === The number of fronds per plant averages about 6-8; with some plants having as few as 2 fronds, ranging up to a maximum (that we have seen) of 17 fronds. The above ground height level of the fronds ranges from an average of approximately 60 cm to a maximum of approximately 90 cm. This cycad (along with most other Section Parazamia species) produces new fronds irregularly in the wild, except after a bushfire, when most plants produce new fronds. At the stand near Richmond, new fronds are normally a distinctive blue-grey colour with vivid pinkish-red callouses where the pinnae join the rhachis. Very rarely, new fronds with an albino-like golden-bronze colour are produced. Over time, however, the frond colour changes from blue/grey to green; and, likewise, the callouses also undergo a colour transformation and change from pinkish-red to a yellowish or creamy-white colour. Plants in this habitat location are extremely attractive when new fronds are produced; though they become less attractive as the frond colour changes with the passage of time and, also, as a consequence of deterioration in the condition of the fronds that sometimes occurs because of damage caused by leaf-rolling insects. In other locations, the frond colour varies, in adult plants, from grey-green to dark green.
