It's been about 13 months since I sowed this next group. This was the most disappointing group because of all the seeds that refused to germinate.
Ariocarpus trigonus 'elongatus' [MG43]. I think these are getting overexposed to the light, so I have put them under some parchment paper (the kind bakers use) to help them go green again.
Echinocereus fitchii ‘reichenbachii’ subs. bergmannii L 1061 Las Crucitas 100m, Zaragoza, Tamaulipas, Mexico [MG247.75]. I wasn't sure what to label this, since it seems there is some contention on whether "fitchii" is a good species or if it should be brought down to subspecies? The Lau number returns "E. reichenbachii fma." and E. fitchii subs. bergmannii doesn't show up much and isn't listed as a synonym in
Lodé's index of taxa, so I went with
Echinocereus reichenbachii subs. fitchii 'bergmannii'.
Anyway, I noticed these guys have stayed somewhat wrinkly despite watering a week ago, and stayed sun-stressed despite being put under shade longer than that, so I pulled them out to see what was going on. Sure enough, all of them had root rot.
I cut off the rotted end and left them to dry for a week. I don't have much hope for these since there isn't much stem left to root, but we'll see. I'm not so sure why they rotted, but they did get rained on a couple weeks ago when the weather was cooler, so I'm hoping it was that rather than overwatering by me!
Geohintonia mexicana. Slow, but at least not Aztekium slow.
Gymnocalycium spegazzinii 'recii' JO 820 Quilmes, Tucuman, Argentina [MG489.75]. Mesa has kept the varietal name as 'Gymnocalycium spegazzinii var. recii'. These guys aren't in a hurry either, but they are coming along nicely.
Mammillaria lasiacantha SB 1063 Hipolito, Coahuila, Mexico [MG725.1]. The seedlings, very feathery, almost like M. plumosa, are dwarfed (can you see all 4?) by the very obvious hitchhikers.
The one in the back may be M. spinosissima? There's another, smaller seedling on the right that may be the same, but could be something else. Not sure what the other 2 mystery Mammillaria seedlings are, but one has two heads!
Recent picture below, some time after I put them in their own pot and in probably too much sun.
Sclerocactus mesae-verdae SB 1010 South-West of San Juan County, New Mexico, USA [MG1220.1]. The only two seedlings that germinated, joined by two P. knowltonii seedlings. I really like this cactus. Claimed to be difficult on it own roots so it will be a test for me to keep alive long enough for it to grow into its mature stem.
Kadenicarpus pseudomacrochele subs. minimus FO 259 Santa Teresa Devoxtha, Ixmiquilpan, Hidalgo, Mexico [MG1288.8]. Mesa still has it under Turbinicarpus as 'Turbinicarpus pseudomacrochele subs. krainzianus var. minimus'. This one also leans to show thirst.
I failed to keep the following alive (or on their own roots) up to this point:
Ariocarpus scaphirostris SB 829 Rayones, Nuevo Leon [MG39.3]. No germination
Copiapoa longistaminea KK 194 Cifuncho 200m [MG85.7124]. No germination
Copiapoa uhligiana KK 1398 Esmeraldana [MG85.95]. No germination
Lophophora diffusa [MG548]. No germination
Pyrrhocactus villicumensis DJF 362 La Laja, San Juan, Argentina [MG1187.82]. Yes germination
but I killed them by overheating
Gymnocalycium mix, a free gift that came with the Geohintonia seeds. Only a couple germinated, but they soon damped off.
