The spines of a cactus are an obvious threat. They are generally sharp, smooth, and stiff; as soon as you are stabbed by one, it is immediately clear that you’ve gotten too close. Sitting at the base of the spines – or in place of spines – on many species of cacti is a less obvious, but significantly more heinous threat. Unless you’re looking closely, this hazard is practically invisible, and the…

The result of my 'Mammillaria compressa' hybridization experiment. I crossed two varieties with each other: The long thorn variety with 4 spines on one areole and the short thorn variety with 5 spines on one areole.

It's too early to see exactly what the results are, but I got viable seeds that germinated and so far it's good enough for me.

From this batch of seedlings, I will select the Mammillarias with the most spine growth and cross them with my batch of 'Mammillaria bombycina' seedlings of which the same experiment has been done. The results will (hopefully) be cacti that display a large amount of spines that curl outwards (characteristic from the Mammillaria bombycina).

According to Wiki, while they can certainly be tree-like, most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of leaves, enlarged stems carry out photosynthesis.

Areoles are growth hubs on cacti where spines, flowers, and branches emerge. Unique to cacti, they aid survival in arid environments and help distinguish true cacti from similar-looking succulents.
