I have seen it referred to as both hutchisoniana and also fraileana. My seedlings are only a couple of years old, and haven't yet flowered so I can't be sure - the colour of the stamens should sort it - purple-red for fraileana and yellow-green-brown for hutchisoniana.

However, the location at which it was found by Roman Stanek makes me believe that it shouldn't be M. fraileana, and M. hutchisoniana is much, much more likely.

Hi,

Finally managed to get the flowers to open on Mamm. Sp. RS 990. Outer petals white with dark maroon midstripes. Inner petals white, with yellow-green stigmas. I would deduce from this that my plant is possibly M. Hutchisoniana. Any comments please.

It certainly sounds more like hutchisoniana than fraileana. Did you check the colour of the stigma? that of fraileana is very distinctive as I expect you know.

I'll check my seedling to morrow to see if it also has obliged while I have been away.

Hi Chris,

Yes, as stated stigmas are yellow-green. Not as M. Fraileana, which are dark pink, I believe.

Whoops, that'll teach me to read the whole message first before answering - or maybe I'll blame jetlag.

No, Maurillio, I was answering Delandmo's messgae, as he does say there that the stigmas are yellow-green.

Derek,
I have checked my two plants, and one must have flowered while I have been away, so during the last 3 weeks. Unfortunately it is just a dried up remains now.

The flower on your plant doesn't immediately say to me M. hutchisoniana though. On my plants of M. hutchisoniana, the petals are longer and curl outwards a little, giving a star shape to the flower, and the stigma is more olive green on most of my plants. This flower reminds me more of M. goodrichii in its rectispina form.

BUT....I believe that there is a lot of uncertaintly as to where M. goodridgei (or goodrichii) fits in, and apparently plants looking like the island plants have been found on the mainland, but close to the Pacific coast. Jaraguay, which is where RS990 comes from, is mid-way between coasts.

I suspect that it is a form of M. hutchisoniana but an interesting one for sure. You should write some of these discussions up into an article for the Mammillaria Spciety journal! I'm sure Bill Maddams would welcome it.

Hi Chris,

The photo wasn't the best, but the stigma was more greener than it appears. Not a dark green but more lime colour. It wasn't open fully today when I took the snap, but hope the remaining buds may produce more flowers to allow for some more shots. Camera not the greatest!


Looking at the photographs in John Pilbeam's Mammillaria of M. Goodridgei (page 113) and M. Hutchisoniani (page 145) I tend to favour the latter. Derek
