growth-analysis of Melocactus

[Tofterigen]

Hi

Since more than 2 years I am the proud owner of a rather imposing Melocactus with a diameter of nearly 6''. It is still my second largest globular cactus but it will soon be beaten by an E. grusonii which is growing considerably faster.

Recently I took a photo from a similar position as more than two years ago to find out if the Melo is growing anyway!

Here are the two comparable pics:

The original pics are much bigger, so I am sure that I have marked the corresponding areaoles! You clearly can see that it did grow! Unfortunately I have no old photo of the profile but it seems that it grew mainly vertically, maintaining ist diameter.

So I have always seen new spines examining the vegetation-point, but never any trace of a cephallium which would help to id this guy.

May be in some years...

Best whishes, Tofterigen

Interesting. I love trying to figure out how much a particular cactus has grown in a season(s). Lots of pics are key!

Thanks for sharing,
