Fraileana ?

Does anybody have positive ID for Sp. RS990.

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.

Thanks Chris, I too have read the other alternative as M. Hutchisoniana as well. Mine is only a baby . 2yrs,came from you actually. As you say we'll have to wait for flowewrs.

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.

is possible to have some pictures?

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

i am sorry....
i have read the whole message, but maybe there is something that i have not translated well....

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

Hi, hope picture comes out. Derek.

fiuuuuuuuuuu....
i thought i had written something stupid.

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

Its 8 years since this thread started, and as I have been checking on my Baja plants, I realised that this one, largely ignored by me in the meantime, deserved some further discussion. From the flowers, I certainly can now rule out fraileana as an ID.

Here is one of my plants, now with 3 heads, the other is still single headed but identical, but still in a 2.75 inch (7 cm) pot. It doesn't look like hutchisoniana to me, though the flowers are similar.



Its size might suggest louisae, though the spine colour and numbers aren't quite right, and anyway louisae is a coast plant, I believe. Is it within the variance of hutchisoniana or is it something else??

If anyone has grown this, do please post here.
