Mammillaria plumosa

This cactus (Mammillaria plumosa) is just beginning to flower again. My yellow lithops flowers are looking bedraggled now, and do not close properly at night.

It is just as well that I have some indoor material at present because it has been raining all day, and looks to be the same tomorrow.

I've backblipped a couple of other images from the Otematata field trip, here and here.
