Some seedling observations.

AfM seedlist 2006...

HP 24/45, these appear to be M.formosa.

List number 457, Speices La purisma. These look very similar to Rog 314, aff picta, from the same list. But they could also be nana/duwei has La purisma is in the state of Queretaro. A state in which picta is not found in.

lolita = barbata

AfM seedlist 2007..

ESP 11/102, priessnitzi, Jalpan, Qro. This is a form of magnimamma but the germinated seedlings are not. They look to be something in the Ancistracanthae, red hooked spines.

If anyone has information on any others from the lists then please let us know.

Can't help here Tam, as I only bought seed last year. Mix ups do happen unfortunately. I germinated some M. carrettii once which turned out to be a magnimamma form, but not from AfM seed.

AfM 2007. M. standleyi E/Sp 10/30 La Aduana, Son. These seem to be mixed up with what appears to be M.prolifera/multiceps.

M.supraflumen ML 302 :- From the Piltz 2009 seedlist. M.supraflumen is a form of M.nunezii. ML 302 is a collection M.jaliscana.

M.scrippsiana SB 717 :- From the Piltz 2008 seedlist. SB 717 is a collection of M.bocensis (neoschwarzeana). Has far as I can tell Steven Brack never made a collection of M.scrippsiana.

M.zublerae H.O. 587 :- From the AfM 2009 seedlist. These seedlings have produced standard prolifera type plants, long spines, fast growing and freely offsetting.

Regarding Rogozinski's M. sp. La Purisma, could this be a M. crinita form (a bit tezontle like)? Rogozinski has been near La Purisma in the state of San Luis Potosi (it lies about 30 km north of the city of SLP) and he found there M. bocasana multilanata and a M. tezontle like plant.
Near there, at La Tinaja, I found M. bocasana multilanata (WTH 605) and M. crinita aff. (WTH 604). The latter sometimes lack the hooked central spine.

I no longer have these plants, has a rule I do not keep any plant without a field collection number. I cannot recall enought to say if it could have been a bit M.tezontle like but I am certain it was not a M.bocasana type plant. I have grown a number of collections of M.bocasana from seed to know what they look like. Is there anything else that grows around there.

Mark.

Another mistaken field number which has just come to light.

On this years, 2010, Piltz seed list was listed M.senilis WK 490. This in fact, should be WK 440 and has been confrimed by Wolfgang Plein.

From last year's AFM ( 2010 ) seed list I sowed item 110d, M.elegans v longicaudata Rog 168. The resulting seedlings look to be something like M.densispina.

Did anyone else sow this seed and if so, what do your seedlings look like ?

Sorry, Tam, I didn't sow that one. There were 6 different seed of M. densispina offered last year, so its going to be difficult to match it back to one of these, unfortunately.
