Contest 75 : Dicussion and related Pictures

[Steve Johnson]

I have some more yellow flowers in Summer for you. Here's my Copiapoa hypogaea:

Started blooming at the beginning of June, and it didn't stop until its last flower of the year on October 24. Next, here's my Turbinicarpus pseudomacrochele. Little pale yellow flowers that usually come in "single file", but this time it was a twofer:

And finally -- another one of my prolific bloomers. Astrophytum myriostigma:

Paler than other flowers I've seen out of the same plant, but yellow enough.

Isn´t it a joy to see all those cacti in their summer dress?!
Here is another one

Steve, that's a great shot of A. capricorne you put in the contest! I was really thinking of putting in my shot of mine, but the pictures I took just weren't as nice as that even when I tried to crop it a bit. So I put in a shot of a stapeliad instead just to make sure non-cacti were represented.

Turbinicarpus pseudomacrochele ssp pseudomacrochele has pink flowers. Or at least white with a pink stripe, usually a very strong pink strip. Such as this:

Ssp krainzianus can have yellow flowers, although it tends to be taller and less wiry. Can't think of anything else it would be, although your plant is very old so hard to compare with my youngsters.

[Jens]

I think so too Steve, but it´s quite a nice plant you are showing.

Maybe it's a krainzianus, then? Here's the Turb I've been calling pseudomacrochele (no ssp ID'd), when the flowers were bigger and opened more in September and October:

I also notice that the flowers were paler than the ones in my photo from 7/7. Whatever the species, it is definitely an old Turb. Plus it comes with a youngster! Don't know if it's a pup or a seedling volunteer, but I first spotted the tiny guy about 18 months ago. Likes to hide in the spines, but it'll pop out a little more when I water. Here we are a week after those Turbs got their last watering of the 2012 season:

So we don't go too far OT here, I'll give you another shot of my A. myriostigma with a darker yellow flower back in June:

Thanks, everyone!

Certainly not P. pseudomacrochele ssp pseudomacrochele. I'd guess that is a seedling. Turbinicarpus tend to pup from quite high on the body rather than from the roots, and that looks like it has its own root going down.

T. macrochele can appear very similar, with slightly thicker flattened spines than T. pseudomacrochele, and the flowers can be almost white but not really yellow like yours.

Based on other photos I've seen, I think you're right -- this Turb pseudomacrochele ssp lausseri from Cactuspedia:

2 seedlings and a pup -- I like that plant! As for mine, I'll take the seedling. Unless someone can give me a more accurate ID, I'll label it as pseudomacrochele ssp krainzianus. But regardless of whether or not I have the name right, it's a wonderful old Turb, and the volunteer is bonus -- I'm so glad to have it in my collection!

[Jens]

It really is a big and well grown plant with all those wavy spines, Steve.
Here is a picture of what grows under the name T. macrochele in my place (but I got it second hand too and am not completely sure of the name either)

Wish I could take credit for the photo from Cactuspedia, but that was someone else. If you're talking about the ones I posted up before that, then thanks!

By the way, I have 3 Turb polaskii seedlings that flowered constantly over the Summer. It's fun to see when the flowers are as big as the plant!

[Jens]

Yes one of the nice things about Turbinicarpus is their handyness....

Here is another yellow flowering one from last summer

Fantastic variety of different species in the entries ! Way to go.

There are yellow flowering species in all kinds of cactus genera... e.g. Eriosyce

Vote for one not all????? But they are all winners!

[John C]

Great selection of photos this time! This is going to be a hard decision!

[Saxicola]

Agreed! This is the first time in a year that the number of entries has been enough to go onto a second page. It will be interesting to see how the voting plays out.
