Wow, the first does look like a Mammillaria. Those huge centrals are wild. The second may be an Oreocereus.

2nd plant is definitely a Mam as well, you can tell by the flower growing in the fuzz between the 'nipples'. On other cacti the flowers only grow from the areoles. I have a similar one, sorry I can't tell you the species.

hey David,

i know i'm not being helpful, but i just wanted to say; you always present the most amazing photos! kudos.

Bri.

Hey David , I'm in san diego too ... I didnt know they sold cactus at farmer's market ... I need to go there sometime ... Although I get alittle annoyed with all the hippies in OB . I have some Mamm's I've collected here and there ... I keep thinking I should sell them but then I go out to look at them and I end up keeping them .

Thanks Bri for the photo compliment. I don't use a fancy expensive camera. It's a Canon Powershot SD630 which I got for FREE after my previous older model crapped out. When I asked the guy at the camera shop if he could fix it, he suggested I send it back to Canon, who sent me a WHOLE NEW CAMERA. It's only 3.5" x 2.25" x 0.75" and I often wear it on my belt in a small case. Not much bigger than a cell phone. It has a nice "close-up" feature which really puts things in focus as close as 1 inch from the lens.

hey David,

sounds like you got a pretty good replacement camera. i am a Canon man. have had many a' Canons. the macro (close-up) standard on yours is really good. keep the photos coming. love seeing sharp photos of people's plants. i will start posting some of mine soon as i figure out how to.

Bri.

Posting photos is easy if you use photobucket.com. First figure that out (it's FREE, not difficult, but the ads can be annoying). Each of their thumbnail presentations has automatic popup. Choose the one labeled HTML CODE, copy and paste into your message. Let me know if you need more help. I want to see your photos.

Here is a link that might be useful: Photobucket

For the first one, maybe M. muehlenpfordtii and maybe M. polyedra for the second?

thanks for the help with posting, David. it's too dark to take pics today and i'm workiing a long day tomorrow. but will take some pics on monday and post!

Bri.

here are pics of some of my cacti that i don't have names for. hopefully someone can please help me ID them.

David: hopefully this works! let me know what you think?

this is one of my favorite cacti. it stays this brown color consistently through the seasons and sun exposures.

thanks in advance for any ID help!

Bri.

just in case the pics don't come out, i'm attaching a link to the photobucket alhum.

The first one looks like a Rebutia I had decades ago. It didn't live long enough for me to find out exactly what species it was--that was the year that I discovered that not all cactus like full sun in the desert summer!

The others are mostly mysterious Mammillarias, except for plant #5, which looks like a Parodia.

Hope that narrows it down some.
Kevin : )

Hadrian, you should have numbered the photos ...

Some suggestions:

1. Lobivia arachnacantha
5. Oroya neoperuviana
8. Mammillaria albata
9. Mammillaria matudae

Kevin, tjicken:

thanks for the help! that was very useful. and i will number the photos next time i post.

Bri.

Well, 6 & 7 are Sulcorebutia mentosa. I have it and have ID'd it as that... If it is wrong, please someone let me know. Also I have numbers 1, 3 & 9. No. 1 is Lobivia arachnacantha and No. 9 is M. matudae as tjicken stated. I have never been able to ID number 3. Hopefully someone can.

Sorry paulzie32, but neither 6 nor 7 are S. mentosa (and for once I can say that I am 100% sure), they are two different Mammillaria species. I have known what species no. 6 is, but it doesn't come up right now.

thanks for all the help guys! my plants are appreciative of their newfound recognition.

Bri.

A have thought more about no. 4 and 6. They both resemble forms of Mammillaria spinosissima, but I have not found a perfect match.

And don't take the species name for the one I think is an Oroya too seriously, they are variable. It was just the first that struck me.

Well, I thought it was a sulcorebutia as that's what mine was labeled as but maybe it is Oroya neoperuviana

Here is a link that might be useful: http://www.cactus-art.biz/schede/OROYA/Oroya_neoperuviana/Oroya_neoperuviana/Oroya_neoperuviana.htm

The areoles and spines on Oroya and Sulcorebutia look similar, but the body of this plant is different from a S. mentosa, which has more defined tubercles, and the look and arrangement of the spines doesn't fit mentosa very well either.

Considering the huge variability within Sulcorebutia I cannot swear that this plant isn't one (odd-looking, and I have no idea of what species it would be), but my bet is still on Oroya. A flower, or at least a bud, would probably rule out one of the genera as they look different and appear closer to the apex in Oroya.

I'm leaning heavily toward Oroya; either the O. peruviana or the O. borchersii. Only flowers will let me know which one for certain. I hope I get some this year.
